COMMON PROBLEMS OF EXISTING PUBLIC APARTMENT BUILDINGS IN VIETNAMIAEME Publication
The aim of this study was to investigate the current condition of existing public apartment buildings in Vietnam. In the old apartment buildings, problems included structural failure, aging, impact of outdoor environment, poor indoor and outdoor living conditions, and lack of service facilities. In the newly-built high-rise buildings, poor outdoor living conditions, lacking of natural lighting, polluted air, inconvenience access and high level of traffic noise are observed due to high density of buildings constructed in a land area. In addition, there are high risk at fire and difficulties in firefighting and emergency evacuation where hundreds of residential buildings were found not to comply with fire safety standards. Improvements are recommended at the end of this research for minimizing, even totally eliminating current shortcomings of existing public apartment buildings. Throughout the study, relevant parties and authorities enable to fully understand quality conditions of existing condominium buildings and to propose proper corrective actions
Readjusting the current trend in Electrical Power Engineeringvivatechijri
In this paper, the electrical power education curriculum is analysed from the viewpoint of the electrical power industry and from the viewpoint of young people that contemplate their future academic study. From the perspective of young people in industrialized countries contemplating their future and the possibilities of an academic study, the current curriculum in (power) engineering lacks attraction. The number of freshmen still shows a decreasing trend. This paper is aimed to be a contribution towards readjusting this trend.

Strategic Issue That Universities Must Deal With In The Next Decadenoblex1
Some strategic issues will shape the university's future for the next decade. Indeed, all of higher education will be changed in the next ten years by the developments we have in mind. Among these strategic concerns, two appear to be the most important. The first is resource availability and government oversight. The second concerns academic programs. Let's begin with resource availability and government oversight, where four sub-matters will dictate the way our campuses develop.
- One, we will continue to deal with cost containment, productivity, and accountability at state and federal levels.
- Two, federal policy will continue to determine funding levels for student aid, research and health care.
- Three, state funding policies and priorities will continue to have significant impact on us.
- And lastly, market-driven changes in health-care delivery will greatly influence all universities, particularly those institutions with medical schools.
The second strategic issue involves academic programs. In this category, six major subsets should concern us. They are:
- The basic matter of access to higher education.
- The quality of teaching, learning, research, and scholarship.
- The increasing need for life-long learning.
- The internationalization of education and commerce.
- The responsiveness of our public service outreach to societal issues.
- The threat of increasing competition from for-profit higher education organizations.
Now, which technologies will affect higher education most dramatically in the next decade? I feel confident that five are likely to challenge us the most. The first of these five is the Internet and the related telecommunications and computer technologies. The remaining four are genetics, materials, nano-structures, and molecular biology.
Of all of those, I think the most important technology in terms of its effect on academic issues, and also on the other technologies I mentioned, is the Internet. That includes telecommunications and computers.
Look at the six issues we face. Access to higher education will be dramatically affected by telecommunications and computer technologies. So will the quality of teaching, learning, and research. I don't know whether the coming changes will be positive or negative, but there will be changes.
It also seems obvious to me that telecommunications and computers and the Internet will increase the need for lifelong learning. Continuous education will be needed for people to advance - or even just to stay current - in most fields. And how will we meet that need? I believe it will be through the Internet. It will be at once the catalyst for great change and the tool by which we respond to the challenge.

Integration of Advanced Protocols for Detection and CommunicationSachin Mehta
Collision Communication System 2.4 (or CCS 2.4) detects any sudden change in a vehicle’s mobility and then wirelessly exchanges information such as Vehicle Identification Numbers (VIN) and license plates—revolutionizing hit and run detection. Advanced technologies and protocols were adapted to develop this revolutionary System that includes everything from Xbee Microcontrollers, 3-Axis Accelerometers, DigiMesh Network Protocol, and Data loggers. Once a collision is detected, the DigiMesh module activates and searches for a nearby module that has also been activated in order to compare accelerometer data. If the accelerometer data matches between the systems, Vehicle Information Numbers (VIN) are traded. These systems are all enveloped in a way that yields a potential for major hit and run deterrence that will assist law enforcement, insurance companies, and consumers themselves.

Geological Investigation of the Mono Basing using ArcGISSachin Mehta
The various geological activity taking place around the Mono Basin Region is extraordinary—and it being the oldest lake in North America, our analysis in this paper makes it even more astounding. Determining the relationships among the geologic points in the region and whether they had effects on one another answered a major question that could help in later studies, research, and work in the area. The particular toolsets used from ArcGIS, such as the ‘Generate Near Table’ analysis was just one of the many incredible and useful ways to gather such important data. Finding that the lake levels of Mono Lake fluctuate a great deal was another important output that occurred from our analyses with ArcGIS. With the Mono-Inyo and volcanic craters occurring in and around the region, our analysis on these particular geological features could possibly help future studies take place.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Introduction to Electrical Circuits for K-12 in Reno, Nevada
1. Universityof Nevada,Reno
Abstract
By: Paul Waite
Edited by: Sachin Mehta
The lack of student interest in engineering has increased at an alarming rate over the past years.
While other world nations are maturing into more technologically advanced countries, American
jobs are being outsourced and the United States economy is being threatened. For the United
States to remain both competitive and innovative, science and engineering principles need to be
taught on a much higher frequency.
The Simple Electrical Circuits demonstration is designed to increase adolescents’ interest in STEM
education. STEM, a United States government acronym, refers to fields of study in the categories
of science, technology, engineering, and mathematics. A short lecture introducing simple circuits
and the fundamentals of electricity was given. Next, students were given the opportunity to create
standard parallel and series light bulb circuits. The combination of an informative lecture and
hands-on project is intended to produce an increased interest in engineering and mathematics.
This project design is expected to procure at least a 20% increase in STEM interest for sixth
graders. The Simple Circuits demonstration will be a broad approach to increasing student interest
in science and engineering. The youth who become more intrigued in science after completing this
project will likely perform better in technical classes and hopefully choose to pursue a STEM
career.
Introduction
By: Kevin Vees
The problem statement revolves around the problem with the current school curriculum and how
those issues can be addressed. The design concept for the project is then discussed. This section
details the group’s plans for the project and what materials are required. Following this, the
literature search section looks into what previous experiments have been done and what the
outcome of those experiments was. The methods of project implementation will detail specifics
of the Simple Circuits project. The instruction manual will then be discussed. This will
demonstrate how the experiment is done from start to finish. Finally, the project management
reveals information about the team which will help meet all overall goals, deadlines, individual
tasks, as well as the team charter. The marketing section will be discussed next. Marketing explains
how the Simple Electrical Circuit project can be marketed to any school system. The experimental
analysis will then delve into the aftermath of the project, and will determine what went well as
well as what can be worked on.

Problem Statement
By: Kevin Vees
Technology is quickly taking over the world. Whether it is a new cell phone upgrade every year
or a simple computer upgrade, technology drives nearly everything in the modern world.
Unfortunately, this technology does not invent itself. There will always be a need for engineers to
develop new technologies in the world. Whether it is that new sophisticated computer that just
came out, or simply heating up some leftover food in a microwave, electrical equipment affects
everyone. Anything that is plugged into a wall socket or runs off batteries has some sort of circuit
in it that was designed by an electrical engineer. Since engineers are so important in today and
tomorrow’s world, it is odd that they are so rare. According to the Bureau of Labor Statistics, “of
the 3.2 million youth age 16 to 24 who graduated from high school between January and October
2010, about 2.2 million (68.1 percent) were enrolled in college in October 2010” [Bureau of Labor
Statistics, website]. Out of those 2.2 million students that continue their education, the United
States only contributes about 70,000 new engineers a year [CS Monitor, website]. That means that
out of those 2.2 million students that go to a college, an unbelievable 3.18% turn out to be
engineers. In order to put this number in perspective, Fig. 1 visually shows how small that
percentage is.
Fig. 1: United States College Undergraduates.
The reason for the low level of engineering graduates is debatable, but the K-12 curriculum
suggests that this is due to the lack of engineering experience that these students actually get. An
adolescent student could likely graduate from high school without knowing that engineering is a
possible career path, let alone which engineering field would best suit that person. The fact that a

high school graduate might not know about engineering as a possibility impacts that student’s
future directly, and it affects the whole society. There is no doubt that engineering is an in-demand
field, and is necessary to further the world’s technology. Without having these engineers to
develop new technology, it simply does not get invented.
Another primary issue with the world is the fact that other countries such as China and India are
taking the market for higher level education jobs such as engineering. Table 1, provided by Times
Higher Education, shows that the top five universities in the world for engineering and technology
are located in the United States. These leading universities show that the United States has an
excellent understanding of engineering; therefore there is no reason why U.S. citizens should not
be able to pursue a career in engineering.
Table 1: Top five engineering universities in the world.
The easiest way to solve this problem is to involve the students with more engineering projects.
These students need to get hands-on experience with different types of experiments that will let
them explore the possibilities of their future. This is what the simple electrical circuit project aims
to do. Using the simplest form of electrical engineering, the students will be introduced to not only
electrical engineering itself, but to engineering as a whole. The objective is to get the students
interested in engineering due to the extensive hands-on experiments that will be performed. These
experiments, though at times are difficult, can prove to be very fun and rewarding. An attempt to
make a fun and immersive experience for these students will be made so that they will pass this
information on to their friends or parents and will overall be influenced to look into the engineering
field.

DesignConcept
By: Sachin Mehta
The planned visit to Ms. Lenesha Marbury’s classroom is intended to create a fondness for
engineering amongst the younger generation. With a project in mind that entails intermediate
math, conceptual ideas, and the use of somewhat sophisticated equipment not just any audience
could have been selected. With careful consideration, the team chose to present to the young sixth
grade scholars who attend Anderson Elementary School in Reno, NV. Recognizing that young
students can be easily distracted, an exciting and intriguing lesson plan is formulated in order to
hold their attention. However, amusement cannot be unaccompanied during the visit to the
classroom. An underpinning of engineering and the sciences will be introduced, studied, and
practiced. Table 2 displays the approximate amount of time that will be spent discussing various
principles related to electricity and circuitry.
With a limited amount of time and a great many students with which to work with, only underlying
electric phenomena with basic applications can be selected for the curriculum. Learning how to
construct a simple circuit and illuminate a light bulb while understanding the theory behind the
procedure is the main purpose of the classroom visit. In order for younger generations to be
interested in math and science, their curiosity has to be stimulated at a very young age. In fact,
America’s competitive edge depends on an educational system able to provide younger citizens
with a background in mathematics and science [National Science Foundation, website]. These
types of articles give light to the realization that certain measures need to be taken in order to keep
that competitive edge in the United States. The hope for the classroom visit is that discussing
electricity—a fundamental building block of this planet—can and will help in captivating the
young students.
Table 2: Original Lesson Plan and Essential Concepts
5. 5
The main demonstration will involve a comparison between parallel and series circuit networks.
By connecting a bulb (of yet to be determined power) to the batteries, the students will see firsthand
how the voltage and current in an electric circuit can vary so greatly by a change in the arrangement
of those same batteries. By arranging two nine volt (V) batteries in series the voltage rating will
double, while the amp hours (current) will not change. When connecting two of the batteries in
parallel the voltage will not change, however, the amp hours (current) will double. A diagram
comparing these two principles is shown in Fig. 2 [Electric Circuits, website]. Common
terminology such as: “load”, “source”, “path”, and their respective definitions will be described to
the students in order to familiarize them with these everyday phenomena. Additionally, the
application of Kirchhoff’s laws will be portrayed because of their relative simplicity. Kirchhoff’s
voltage law states: the sum of the voltages around a closed loop equal zero. On the other hand,
Kirchhoff’s current law is defined as the sum of the currents entering a specific node is equivalent
to the sum of currents leaving that same node. Although these two fundamental theorems are
usually taught to students at the high school and university level, their application to simple circuits
is substantial. For example, after the students construct their very own circuits and a voltmeter
measures the actual voltage, they will be able to analyze their circuit with Kirchhoff’s voltage law
and compare the two numerical values. By doing this, students can grasp another topic engineers
cope with every day: experimental error.
Fig. 2: Batteries connected in series versus parallel.
Stipulations that will apply when working with the young students include, first and foremost,
acquiring a parent/legal guardian signature that allows the student in question to handle possibly
dangerous equipment. Although injury is highly unlikely during the exercise, precautionary
measures such as obtaining signature forms is imperative for the school’s sake and the instructors
themselves.
The first task on the agenda after arriving at the school will include a brief overview of safety
protocols. For example, a current of only 50 milliamperes (mA) can cause respiratory arrest,
extreme pain, and extremely severe muscle contractions [Princeton University, website]. No
6. 6
material will be handed out until the completion of the safety review. By separating the class into
groups of three, the monitoring and assisting will become a great deal easier. To begin, each group
will be given all the appropriate materials. The students will need to use the concepts discussed
beforehand to engineer their own circuits and apply the voltmeter/ammeter to measure their
respective elements. In order to further demonstrate principles, mathematical formulas relevant to
circuit analysis will be used. Equation (1) describes Ohm’s Law, a fundamental theorem of
electricity.
𝑉 = 𝐼𝑅 (1)
Additionally, important persons who have been influential in the study of electricity will be
examined including Andre Ampere, George Ohm, Thomas Edison, and Albert Einstein. Important
elements will be pointed out, such as the fact that electrical history goes back long before Christ
and individuals such as Ampere were instrumental in improving existing theories and naming
terminology [Electrical Code, website]. Delving in to the history of electricity and the people
behind the principles will be an important and enthralling topic, in the hopes that the students gain
a broader spectrum of knowledge.

Introducing students to engineering fundamentals is routinely accomplished with the study and
implementation of basic electric circuits. Generally, students will build simple circuits using a
battery, wires, and light bulbs. This allows the examination of how electricity is conducted through
a light bulb using a battery as a power source. Students will also able to observe the differences
between a series circuit and parallel circuit by building each type of circuit.
The projects in the past demonstrate the use of parallel and series circuits with only one battery
and multiple lights such as Christmas lights. The procedure starts by connecting a 6V alkaline
battery into a simple circuit made of multiple light bulbs. The light bulbs are configured into
parallel and serial circuits and the students are shown the difference between the two simple
circuits [Teach Engineering, website]. The simple circuit is shown in Fig. 3.
7. 7
Fig. 3: Simple circuits demonstrated with multiple light bulbs [Comparing Parallel Series Circuits,
website].
In the planned lesson, simple circuits will be demonstrated with more than one power source, most
likely 9 V batteries. The students will still use a light bulb in sacrifice of Christmas lights described
in the previous teachings of this lesson; regular incandescent light bulbs will be used. Basic
computer fans will also be included to demonstrate the difference in current and voltage between
circuits in parallel and series. Additionally, the students will be asked to hypothesize on the
outcome of each device used to demonstrate the principle. To allow the students to use their and
develop their reasoning skills, the students will be divided into groups after hearing the lecture that
will be provided. Each group will receive the same materials, schematic, and explanation of the
circuits used as shown in Fig. 4. Students will be asked to commit to one answer with the help of
the equations behind the principle. Moreover, rewards will be given to those that correctly answer
which bulb will stay illuminated the longest.
Fig. 4: Schematic given to the students.
The planned lesson allows for plenty of deviation as well. While the plan is to teach the students
about circuits with multiple batteries, the demonstration of multiple light bulbs arranged in series
and parallel can also be fulfilled. In conclusion, this lesson plan allows the students to be taught
in a more fulfilling manor with multiple demonstrations, interactive approach, and the testing and
forming of deductive reasoning from the students.

Criteria
In order to assure project contrivance, three success points were established: the material chosen
for the demonstration must reinforce the current curriculum of the class, students show interest
and enthusiasm for STEM education, and that all participants have fun.
Students will be using batteries, wires, and bulbs to complete their circuits; they must know, at a
minimum, the role that each component takes in a circuit. Students are introduced to electricity
as early as Kindergarten; by the fifth grade, they should be able to identify the necessary circuit
elements and combine them to make a complete circuit (WCSD, website). The design project is
most suitable for sixth graders in Washoe County because the circuit elements are a review topic
and the circuit layouts are generally new information.
The demonstration is designed for students and
should therefore maintain high levels of student
interest. To keep sixth graders' attention, sufficient
time must be spent interacting with the circuitry
elements. The largest amount of class time is to be
spent building circuits. During this time, it is
important to allow for student creativity; the design
entails that students build their own completed
circuits using the materials combined from two
groups. This portion of the demonstration will
provide students with an experience that builds
confidence. Fig. 5 shows an example circuit that
two groups can make with the materials provided.
Students should be encouraged to experiment with
a number of circuit arrangements as time allows.
Testing Procedure
Student groups will design the assigned circuits in small groups. Student success is assessed by
verifying that the circuit layout is correct and establishing that the circuit is completed.
Throughout the construction phase, student circuits are periodically checked for completion;
once a group has completed the assigned circuits, they are free to build their own circuit design.
To establish success for this phase, the criteria is that circuits can use the supplies of two groups
and that the circuit must be complete and each bulb be lit.
ClassroomSetup
Setup for the demonstration is minimal; however, there are a few important steps to take for
success. The supplies for each group are readied before the start of the demonstration, this will

reduce down time and keep student interest levels high. Appendix A contains a list of the
supplies for needed for each group. During the introduction, students are briefed on circuit
diagrams. When students build series and parallel circuits, Appendix A is used to display the
respective diagrams. Most importantly, before students are allowed to use any of the materials
provided, they must be informed about what general safety precautions to take when handling
these equipments. Appendix A lists these safety precautions for students to review before using
the provided materials. Being prepared for the demonstration requires detailed review of all
information in Appendices A and B.
Instruction Manual
By: Hans Meyer
The detailed instruction manual is in Appendix B. To begin, the required materials for the
instruction of the lesson are shown in Table 3 along with a total projected cost. The budget
projected is for enough materials for 8-10 groups and comes to a total amount of about $45. If the
lesson plan is to be repeated, many parts can be reused, the wire being the most acceptable one.
Therefore, the total cost can be regarded as a nominal fee with few maintenance costs.
Table 3: Shows a budget of the lesson plan.
Item Price
9 Volt Batteries (10) $20
Battery Connectors (10) $6
Light bulbs (22) $11
Wire (20’ spool) $7
Total $44
To begin the lesson, the facilitator must provide an appropriate atmosphere that allows the students
to learn the basics behind simple circuits. If the facilitators are not confident with their competence
of simple circuits, the internet can be used an additional aid [Engineering Interact, website].The
facilitator should provide a sketch of the two different circuits to be built shown in Appendix B.
When providing the sketches, a simple lesson involving voltage should also be provided. It is
suggested that the facilitator should attempt to openly quiz the students by asking questions such
as what will happen to the light bulbs in the different arrangements. At this time, a quick discussion
of safety should be clearly communicated. Once the classroom has a basic understanding of the
circuits and safety, the facilitator should demonstrate the capability of the battery to power a single
bulb. After the demonstration, the materials should be distributed to the groups, and the students
should be given approximately 20 minutes to build the two circuits. A complete timeline of events
is in Table 4 for a time efficient lesson. This lesson will demonstrate an important and fundamental
aspect of electrical engineering if carried out appropriately. The hands-on experience will help to
stimulate and inform the students better.

ProjectManagement

Scheduling
Upon assignment of the proposal project, the group designed an approach that includes four
stages of teamwork leading to a completed avocation: formation, brainstorming, normalizing,
and performance.
In the formation stage, the group was given a task and then converted into a team. After this, the
first team meeting took place; during this meeting group roles were decided upon and relevant
past experience was discussed.
The group's second meeting was where brainstorming began. The goal was to decide upon a
topic for the proposal assignment. However, in order to properly make group designations, it was
first necessary to discuss how decisions will be made. Using an open idea forum, possible
outcomes were discussed and freely elaborated upon. After the time was up, team members
wrote down their top three choices from the earlier forum. The team rejoins and compares lists.
The most frequent responses were taken to a small three item poll and voted upon to obtain a
final decision. Using this method, the team decided on a project that teaches fundamental
electrical concepts and circuitry.
With roles and a clear objective distinguished, the team was able to move forward to the
normalizing stage. Normalizing is where team members produce a single product from many
smaller parts. Each team member has contributed different content to the final proposal, this
content was pieced together and made into a single, cohesive work. This process includes peer
review and team unification for a presentation given which summarizes the group's proposal.
During the performance phase, team members were not in deliberation; the team was focused
and each member completed a given task. The pinnacle of the performance phase was the
11. 11
delivery of the circuits presentation to a class of sixth grade students. This phase receded into
another group presentation summarizing the outcome of the demonstration.
Fig. 6 is the team's Gantt Chart. This plot provides the general time frame of completion for
stages of the project. Formation and brainstorming tasks are connected with a solid line and
circle endpoints, normalizing tasks by the solid arrow tipped lines, and performance tasks have a
dotted line with circle endpoints.

Materials
The proposed project requires one spool of light weight electrical wire, about 15 small lamps,
and 15 9V batteries with connectors. Table 5 demonstrates the approximate total cost of the
materials that need to be purchased. Prices listed are relative to the current market [Radioshack,
website]. The original estimated total in Table 5 was shown to be a great over estimation; the
final cost was significantly less than $100 dollars. Ordering the supplies from the internet
reduced the cost to only $44 dollars.

Resources
During the formation stage, a team charter was designed to help focus the future work of the
team. Before completing any proposal related the task, the team decided upon a few key points:
first and foremost group members agreed to be committed and produce the best work possible,
also the group placed heavy emphasis on promoting engineering to young students, finally the
group agreed that the majority of work will be completed with all group members present or in a
meeting format.
The makeup of this group is complemented by each member's skills, background, and
personality [Holland Personality, website].
Kevin Vees is a junior of Electrical Engineering. Kevin has a social personality which is vital to
group function. Kevin's positive attitude toward problems and assignments has repeatedly shown
to motivate other group members into display the same trait.
Hans Meyer is a senior of Civil and Environmental Engineering. Hans has a realistic personality
type. Being present tense oriented, Hans helps keep the group on track by structuring and
sometimes deciphering group plans into a goal that is attainable.
Sachin Mehta is a junior of Electrical Engineering. Sachin displays an enterprising personality.
He consistently offers new ideas for how to improve and differentiate team stratagem. Sachin has
been known to provide clever solutions to problems that other team members did not know
existed.
Paul Waite is a junior of Civil and Environmental Engineering. Paul is investigative; he typically
will analyze a problem and note each detail that is relevant to solving that problem. When
planning, this is particularly helpful because some ideas proved to be too complicated to
complete.

Acceptability
The Simple Electrical Circuit project is designed for students in the lower end of the K-12spectrum
of school. Introducing this simple engineering concept to students by hands-on experiments will
boost the kinesthetic learner’s interest as well as the understanding for the subject. This experiment
also appeals to the auditory learners because there will be a pre-experiment lecture prior to the
students getting their hands on the materials. Visual learners will also be able to learn from this
experiment because the experiment will be demonstrated using pictures and analogies of physical
objects, such as how a circuit works similarly to a water hose.
The supplies needed are as follows: 20 9-Volt batteries, 20 battery clips, and 10 light bulbs. These
materials can be very expensive if purchased at a local shop; however, if researched properly and
purchased online, the price can be reduced by over half. Ultimately, this brought the cost of this
experiment from very expensive, to very affordable. The cost for this experiment is $44 making it
an affordable experiment when split between group members. If this were done by a single person,
it could prove to be a bit “pricy” depending on that individual’s budget. The operating cost for this
experiment is only time, considering all supplies being used are self-powering.
Adaptability
The Simple Electrical Circuit project was initially implemented for a sixth grade level. This
experiment can be altered to fit any K-12 classroom, and it can even go as far as to be appropriate
for a college level classroom without purchasing any additional supplies. For students below sixth
grade, the experiment would have to be pre-built for the students, and the students would not be
allowed to experiment freely with the batteries. This would remove any possibilities of the students
not getting the experiment to work and allow the students to get a working circuit by simply
plugging in the battery to the holder.
For students above a sixth grade level, the students would be required to use mathematical
equations to calculate the current and voltage in the circuit. Different batteries could also be used
with different light bulbs to see the difference in the circuit. This would allow the students to apply
their current knowledge and get closer to how an engineer would analyze a circuit on the job. For
college level students, the experiment would be relatively the same; however, the students would
be asked to solve for various variables such as the luminance of the light bulb being used.
K-12 Curriculum
The concepts applied in the Simple Electrical Circuit project fit into the K-12 curriculum for all of
Reno, NV and Northern Nevada. Table 6 summarizes what students learn in the K-12 system,
14. 14
going into detail that students of nearly any age will have a basic understanding of how circuits
work. Students are first introduced to the simplest circuit in Grades 3-5. The students will
understand how to organize an electrical circuit using a battery or generator, wire, or complete
loop through which electrical current can pass. In Grades 6-8, the students will have improved the
knowledge of electrical circuits to a level of understanding the means of transferring electrical
energy to produce heat, light, sound, and chemical changes. The next level of electrical circuitry
is taught in Grades 9-12 and teaches the students how electricity is transferred from generating
sources for consumption and practical uses.
The sixth grade students that will be participating in the experiment are at a perfect level for the
subject that will be taught. The students will have a basic understanding of how a circuit loop
works, which will be the foundation for this experiment. Additionally, this experiment allows the
students to take what they have already learned out of the textbooks and apply it to a real world
situation. This experiment will be rewarding for the participants and will “kick start” the student’s
interest in the engineering field, and overall create an interest to enter the field of engineering.

Experimental Analysis

ClassroomObservations
Visiting the sixth grade students at Anderson Elementary in Reno, NV proved to be beneficial
for the students as well as team two-α. The generation and synthesis of the Simple Electrical
Circuits design project involved a considerable amount of preparation. Although, as time
elapsed in the classroom, much of the team’s uncertainty and anxiety diminished. Any
apprehension the team felt prior to the classroom visit faded as the young students became more
intent on learning about electricity and simple circuits.
The presentation was scheduled to begin at 9:30 a.m. It actually commenced at 9:40 a.m.
because the students needed to complete their prior math assignment. Team two-α used this time
to discuss where to setup, where to stand, and the ideal place to situate the materials, as none of
the team members had done a walkthrough of the classroom in advance. The demonstration
began with a quick overview of electricity and the history behind it. Aware of the time
constraints, not a great deal of time was devoted to electricity itself, mainly because it is a
unifying concept that is taught during the third, fourth, and fifth grade [WCSD Core Curriculum,
website]. The principles of circuitry, on the other hand, were the canons that needed to be
defined and illustrated.
As the fundamentals were discussed, most of the sixth grade students seemed to be extremely
engaged and many raised their hands to answer the team’s dictated questions. After sketching a
simple circuit with light bulbs in series on the whiteboard, the class was asked to determine how
many Volts each of the light bulbs used. As expected, most students could not firmly state the
correct answer. Yet, as team two-α explained the theory to the students, heads around the class
started to nod—signifying a sense of understanding.
Before distributing materials to the class, a circuit was quickly constructed on the smart board
projector. In addition, various safety concerns were highlighted, such as the proper handling of
light bulbs and the dangerous effect of touching the positive and negative leads of batteries
together. However, when an individual is explicitly told not to do something, there is usually a
larger urge to do it. Surprisingly enough, all of the students listened to the warnings, and there
were no small fires during the classroom visit.
Each group of three was asked to build two circuits consisting of light bulbs in series and light
bulbs in parallel. The majority of students worked diligently as each member of team two-α
walked around the classroom. The team stopped here and there to talk with the students and
answer any questions. Many students seemed to grasp the concepts that were previously
discussed and had no issues constructing the circuits. When asked to partner up with another
group and combine supplies, the noise level increased two-fold with laughter and smiles being
heard and seen throughout the room. There was a significant amount of creativity amongst the
students when materials and young minds were combined.
16. 16
While the students worked on understanding and constructing larger circuits, a bag of candy was
brought out, causing a frenzy and yet another two-fold increase in the noise level. As the 40
minute mark approached, members of team two-α started to receive an unusual request from
various students in the class. Many of the students wanted to take a battery, wires, and two light
bulbs home with them in order to build circuits in their own free time. This request caught the
members of team two-α “off guard”, but it also marked the classroom visit as a major success.
Survey
The survey created for team two-α’s classroom visit consisted of six questions total. Of these six
questions, there was one free response question where each student was asked to draw a specific
circuit using the correct schematic symbols. The other five questions focused more on the
satisfaction of the students. Two of the poll questions included how much interest each student
had in science and engineering before and after the presentation. This allowed team two-α to
obtain an idea of the change in mind state resulting from the simple circuit presentation. After
the survey was handed out to the class, the students took approximately eight minutes to
complete it. Each team member continued to walk around the classroom, but tried not to help
any students in completing the survey, as this would distort results. A reproduction of the survey
is shown in Appendix D.
Data Analysis
After the classroom visit on simple circuits, each of the 24 surveys was examined. It is
important to note that the class consisted of 15 males and only nine females. This “boy-heavy”
class, as the teacher Ms. Marbury put it, could have been problematic as boys can be more
rambunctious than girls. However, there were absolutely no problems that occurred during the
classroom visit. With nearly a 25% increase in an interest in science, team two-α’s time in the
classroom could be deemed a success. After all, the main basis for the demonstration on simple
circuits was to get the youth involved and focused on an extensive science and engineering based
curricula. With a greater interest in the field, it is more likely that the students will make a
deliberate attempt to learn about the everyday phenomena that occur around them.
The last question of the survey also proved to be of crucial importance. The question asked the
students to draw one of the simple circuits that were previously discussed by team two-α. A total
of 70.8% of the class seemed to have the correct portrayal of two light bulbs in parallel with a
voltage source attached. Although team two-α expected a greater number of students would
correctly depict the circuit, 70.8% is most definitely not a failure. In addition to this question,
the fifth question on the survey also proved an important figure. Lastly, but nonetheless
significant, includes the percentage of students who enjoyed themselves and had fun learning
about simple circuits: 100%. This came as a surprise during data analysis, but reinforced that the
classroom visit was not taken for granted by the students.
17. 17
Error Analysis
During the class visit, there were a few students who seemed to have significantly more trouble
in circuit construction. Some students were detected sitting at their desks with their hands in
their pockets. This seemed to be a result of a lack of instructors. Twenty four students may not
sound like a great deal, but in reality, the elements add up and can cause a bit of disorientation.
In addition, bringing candy to the classroom visit caused a great deal of chaos, with students
grabbing handfuls instead of one piece each. Although the teacher did not object, the students
would have been more focused on the scientific concepts if the sweets had not been brought
along.
Recommendations
Circuit concepts and theory would be more easily taught to students of older age. Sixth grade
students have not learned the advanced math needed to calculate currents and voltages at
different points in a circuit.
Having more animate visual aids, such as a Power Point presentation, would also assist in
grabbing the students’ attention. While the resources necessary to do this were not expected in
an elementary school classroom, the class did have its own dedicated Smart Board. According to
the teacher, this level of technology is now fairly common in elementary classrooms and may be
used to present a variety of visuals.
In terms of organization, placing students into smaller groups (around two students each) would
produce better results. There would not be the “third wheel” that does not get a chance to
participate. Additionally, not enough supplies were distributed amongst the groups, so many
students had to take turns in handling the various material.
Conclusion
By: Hans Meyer
Edited by: Sachin Mehta
With the recent lack of engineering graduates in the U.S., it is apparent that promoting engineering
earlier and to adolescents is imperative. The fundamental sciences have always been required
curricula for K-12 grade levels, but the majority of students and teachers alike, don’t focus greatly
on these topics. This problem has become increasingly evident, in light of the declining number
of engineering graduates in the U.S. The American education system, school teachers, and parents
all need to re-assess this predicament, and take control of the issue before this trend becomes
irreversible.
The goal of this lesson is to create a fun environment for fifth to sixth graders to flex the reasoning
side of their brain. This lesson challenges the students to use basic engineering principles to deduce
the outcomes of simple circuits. The Simple Electrical Circuits demonstration attempts to help in
18. 18
this regard, by providing students with a small, but practical, look into multiple engineering
disciplines. The project is an inexpensive classroom activity which can be easily understood and
implemented by school teachers using the supplied instruction manual. Being easily adaptable to
various grade levels, the project also provides a glimpse into real word phenomena that occur every
day.
The design project provides demonstrations to students, which is aimed at building a greater
understanding of this basic electrical engineering principle. The lesson allows the students to build
and determine the outcomes of simple circuits. This project will be successful with the aids of a
team charter, project schedule, and Gantt chart. The various materials needed for the project total
less than $50, making it a cost efficient and engaging activity. In addition, this activity gives
students a great deal of freedom in circuit construction, and gives students the opportunity to work
with one another—a major underpinning of engineering. With a 25% increase in an interest in
science by the end of the classroom visit, the project proved to be a success.
