For the three students, a major reason for not liking chemistry was the unknowing surrounding the point of each lesson and unit in their lives. I believe
making learning intentions known to students can frame their learning in lessons and help to gain an understanding of the overall picture for the unit.
With my learning intentions in this unit I want to have two specific intentions, and one intention that relates their learning to real–life examples.
Making learning relevant will increase engagement (Hipkins et al.,2002). Sadler (1989) argues that if a teacher and students' ideas surrounding
learning, and quality of the learning are not similar, monitoring of working being produced becomes difficult for teachers and students. I could
introduce learning intentions in two ways. The first is to introduce learning intentions at the beginning of the lesson, which will suit John as it will
reduce his anxiety around expectations on him for the lesson. By knowing what is expected he can work towards these, and enjoy the learning process.
The second way is to complete the learning, then allow students to reflect on the purpose of the class. This will suit Mark and Tim as it will challenge
them to participate in lesson Making learning intentions clear for students it encourages students to reflect against the learning intentions and assess
their progress towards achieving them (Absolum, 2011). Once learning intentions have been shared, it allows students to engage with the lesson

What Chemistry Means to Me
What chemistry means to me and how it impacts upon my life
From the foods we eat and the medicines we take to the products we regularly use, our lives are inextricably linked to chemicals and their operating
principles.
Chemistry is everywhere. The air we breathe, the ground we stand on, the seas we sail, and the variety of living things including our own bodies; all
these are made of substances that we call chemicals. These chemicals interact with one another, and, in many cases, these interactions produce new
substances through processes known as chemical reactions. Over time, in high school I have learned much about chemicals and have mastered
numerous chemical reactions, giving me the ability to modify existing substances and...show more content...
Even the gas and tires in cars we drive, the makeup we put on our faces, the soaps and cleaners used every day, burning wood or other fossil fuels,
chemistry is all around you each and every day. Chemistry is really an amazing subject and works hand in hand with all the other sciences to make
things work. According to Don Showalter he stated that "each of these reactions between substances illustrates a concept of the way matter behaves."
According to Roald Hoffmann "matter is neither created nor destroyed."
Research and deduce from your findings which use of metals came first– was it for weaponry or jewelry
From my research that I have done there is no historical documentation, but the most likely metals are copper and gold because they are both
comparatively easy to find as natural ores, and are both soft enough to use without forging equipment. Both metals were used by many ancient
cultures for jewelry and decorative uses; copper was also used for simple tools. Copper is perhaps one of the most important elements for mankind,
both due to its multiple uses and to its capacity to replace iron in many cases. Starting with making objects out of copper and continuing, as mankind
progressed, with its use as a good electricity conductor and building material, copper was part of everyday life ever since the copper age. Even today's
world, despite new discoveries that brought about artificially made

Introduction
When living in a world such as ours, chemistry plays a large role in how society interacts. Chemistry can be viewed from many different angles because
of its dynamics when dealing with the nouns of life (People, places, and things). With people, chemistry is how he or she connects to their social
conformity. With places, chemistry is the structure and atmosphere that brings about the culture to the arena. With things, chemistry is the accuracy and
measurement that brings the degree of closeness to the true value of its quality. In this paper, one will cover chemistry in terms of accuracy and
precision, the relation to scientific methods, and how...show more content...
What it comes down to is supply and demand and the chance to retain a profit from the precision of the weight and how much to distribute of an item in
most situations. Another angle to which society depends of accuracy and precision of measurement are within the food market. It is important to
understand how to order in quantity that will last from one month to the next. The scientific method
A scientific method is a way to ask questions and answering them by making observations and doing experiments. The steps of the scientific method
are: Ask a question, do background research, construct a hypothesis, test the hypothesis by doing an experiment, analyze your data and draw a
conclusion, communicate your results. When looking at these steps the explanation of them are rather simple. To ask a question means to open the
floor for discussion to gain an answer. Once he or she gains the Intel, he or she will perform a background research to be sure that the information is
credible. From here, one will construct a hypothesis as to why things are the way they are. This will lead to predictions that can be tested in multiple
ways. Then one will test the hypotheses by doing a experiment. The modern interpretation of this test often times will show that the hypotheses must be
falsifiable which means that there are possible ways to identify the outcome of the

Pure water is expensive to produce, is tasteless and lacks in magnesium ions. Magnesium ions reduce the incidence of the hardening of arteries and
therefore are used in the protection against heart disease. The gas chlorine, Cl2, is most useful to purify water. Chlorine kills viruses and bacteria
because it reacts with water to produce hypochlorous acid.

Chemistry Course Analysis
Chemistry is undoubtedly in one's everyday life. Every day, our bodies undergo chemical reactions and our environment that we live in goes through
chemical changes. Completing this course, as challenging as it was, actually taught me so much about important chemical concepts that I didn't even
know or remember learning from previous courses. Our bodies cannot function without chemistry, so it is just as important to learn about the
biological chemical process within because we need to know what is going on in our bodies, as well as in our surroundings.
For example, as a nurse, I use those instant cold packs all the time. However, I didn't know what caused them to turn instantly cold. When ammonium

The first concept or idea that I can use daily is pH levels. The pH of our blood should be about 7.4. If the pH levels increase or decrease, there can be
severe health problems causing the abnormal levels, such as metabolic acidosis (pH level is lower than the normal levels) or alkalosis (pH is
above expected levels). Another concept that I learned about in this course is the purpose of a catalyst in a reaction. A catalyst is used to speed up a
reaction. In the human body, catalysts are enzymes. Enzymes are necessary and crucial to carry out many bodily functions. One of the most
important enzymes, in my opinion, is DNA polymerase. DNA polymerase has the important task of synthesizing DNA molecules. DNA, as we know
from biology, holds all of our genetic material or profile and is what we pass down from generation to generation. Where on earth would we be without
DNA? More importantly, without catalysts, like DNA polymerase, DNA could not be synthesized.
I could go on about how all the concepts we have learned in chemistry have importance in our daily lives. I wish we had more time than the seven
short weeks because there is so much information to absorb. Hopefully, I will be able to carry these concepts with me when I graduate and start my

Essay on The History of Chemistry
Chemistry is the study of the composition, structure, and properties of matter and the changes that matter undergoes (Modern Chemistry, 2010 Holt
McDougal pg. 3). So what if chemistry sounds boring to some people, everyone has their own opinion about a subject that you don't want to talk
about in class or the subject you know so well that if someone asked you a question you could answer in a heartbeat. Well for mechemistry is the
subject I don't know very well at all and is hard for me to learn. It is what most careers are built around now and we are creating more careers for the
future. Chemistry is the way that most of our education is built upon with the careers we have and the careers we will develop over the next couple of

Society has had a lot of different things that involve chemicals now and back in the day such as acids, foods, drinks, and also household cleaners.
These are the things scientists have come up with all of these years and are trying to perfect the products we use in chemicals that have been doing
over the past couple of years. Even when everything we have is trying to help you and be good to you and not just harm you or be bad for you but
everything in this world is either one or the other but never both at the same time. The generation is helping us with the technology we have
advanced because the scientists have made sure they have advanced them for out next generation going in to chemistry and having it so our future
will be able to use it and show their kid's and grandchildren the wonders of chemistry that we have had the chance to use. The stuff we have now
think of all the stuff we wouldn't have, for instance we wouldn't have the medical medicine we have if it weren't for the chemical reactions and the
scientists that helped come up with the ways to use our modern technology we have now. Even when we have all the stuff we still try to advance what
we already know even if it comes out different things to improve what we already know every now and trying to find the concept of science.

How Chemistry Changed My Life
My parents met while working in their town's chemical factory. They never thought much about the side effects of working with chemicals all day
until they had me. When I was born I weighed fifteen pounds and was already able to walk and talk. As soon as my mom and dad realized that I
was different, they took me home and kept me away from the world. They were so afraid that I would be taken away and dissected like a frog in a
lab. My other capabilities did not come all at once. One day, I was playing with my ball in the yard and accidentally threw it into the tree. Before I
realized it, I was floating up into the air to retrieve it without any effort. I could fly! I was so surprised and thrilled at the same time. Another day, my
dad wanted me to guess what he was holding behind his back. I found myself concentrating and discovered that I could see right through him and I
could view the necklace that he was holding in his hands! I was so amazed that I could see things that were hidden from regular eyesight. It was...show

My blonde hair is very long because it grows an inch every week. I have become quite good at disguising my powers, which allows me to blend in
with the outside world. There have been times when I risked being discovered. When I see someone in trouble I always try to help. During these times,
I use my ultra–ego that I named Super Debbie. She is braver than my regular self and has unbelievable strength. Once I was jogging in the park and I
came across two men robbing an elderly woman. I was disgusted that they were not only robbing someone, but had chosen a defenseless senior
citizen. Before I knew it, I had turned into Super Debbie and took those two men in my arms and made them beg for mercy. I do not believe in fatally
injuring the criminals that I encounter, but I like them to feel frightened and uncomfortable just like they make their victims

Chemistry In Chemistry
Chemistry is used in a lot of things in modern day. Chemistry is used to make medicine and drugs and it is used to make food that we consume each
day. Using chemistry these days is vital because drugs are used to cure people and the food we eat should be germ free. Also Chemistry is used for
advancement of technology. Chemistry can be used in physics while our own body is made up of a lot of elements which has to deal with chemistry.
Chemistry is used in making drugs because it is the foundation of medicine. Human beings use chemical reactions to create medication for a broad
spectrum of illness and they utilize medicinal plants and animals. Chemical reactions take place in plants and animals, this result in the formation of
substances in some plants and animals that can be used to treat illness. Chemistry is important to everyday life, because it provides medicine. A lot of
people would be dying right now if chemistry is not used to create medications. Also chemistry can be used to talk about the substances. Like analytical
chemistry which uses instruments and any method used to separate, identify, and quantify matter. It consists of using classical qualitative methods for
separation such as precipitation, distillation, and extraction. After such methods are used the qualities of a given substance may be identified based on
differences in color, the odor it gives, the melting point, the boiling point, and the radioactivity or reactivity of that substance. Classical

Atoms, Molecules, & Elements Essay
Atoms are the smallest entities which resemble the properties of an element and cannot be broken down into smaller parts. Molecules are formed
when two or more atoms are combined. This formation can happen in a variety of ways. When two oxygen atoms join O2 is formed, and when three
oxygen atoms join O3 or ozone is formed. Both of these have different properties. Different atoms can also combine to form molecules. Hydrogen
combines with sulfur to form H2S and hydrogen and oxygen also combine to form H2O. Dmitri Mendeleev's Periodic table is based on atomic weight,
whereas, the modern periodic table keeps the atomic number as the base. An atomic table arranges elements from left to right in a row with the atomic
number and...show more content...
Sodium contains one free electron to donate to form instant bonds like NaCl. Chlorine (Cl) is an example of a halogen. Chlorine requires one single
electron to make eight electrons in its' outer shell. Ultimately the high reactivity of alkali metals and halogens are a result of their unstable electronic
configuration in the outer shell. In contrast, noble gases tend to be non–reactive because these elements have stable electronic configurations in their
outer shell. Helium, for example, has two electrons and neon has eight electrons in the outer shell. These elements do not normally react with other
elements.
Molecules from atoms in similar families, such as H2S and H2O, have the same type of molecular shape and structure. Sulfur is less electronegative
than oxygen making the hydrogen–sulfur bond less polar than the hydrogen–oxygen bond. Due to this difference in polarity, the molecules of H2S tend
to remain in a gaseous state. In contrast, the polarity between hydrogen and oxygen keeps the molecules of H2O together in a liquid state. This
phenomenon is known as electrostatic attraction which is stronger in H2O molecules and weaker in H2S molecules.
The electronic structure of atoms refers to the way electrons are arranged around the nucleus. Four quantum numbers describe this structure and define
the position of an electron in the electronic structure of the atom. These numbers illustrate the structure and arrangement of electrons. This can also

If taken in doses higher than recommended, these may have poisonous effect. Use of chemicals for therapeutic effect is called chemotherapy. Drugs
usually interact with biological macromolecules such as carbohydrates, proteins, lipids and nucleic acids. These are called target molecules. Drugs are
designed to interact with specific targets so that these have the least chance of affecting other targets. This minimizes the side effects and localizes the
action of the drug. Drug chemistry centers on arresting microbes/destroying microbes, preventing the body from various infectious diseases, releasing
mental stress, etc. Thus, drugs like analgesics, antibiotics, antiseptics, disinfectants, antacids and tranquilizers are used for specific purpose. To check
the population explosion, ant fertility drugs have also become prominent in our life. Food additives such as preservatives, sweetening agents, flavors,
antioxidants, edible colors and nutritional supplements are added to the food to make it attractive, palatable and add nutritive value. Preservatives are
added to the food to prevent spoilage due to microbial growth. Artificial sweeteners are used by those who need to check the calorie intake or are
diabetic and want to avoid taking sucrose. These days, detergents are much in vogue and get preference over soaps because they work even in hard
water. Synthetic detergents are classified into three main categories, namely: anionic, cationic and non–ionic, and each

understand all her lessons and I had no problem absorbing the lessons. Butwhen the day after comes, I was already confused on how to do the
Redox. I tried to approach my classmates who are great in Consumer Chemistry. But I always forget it after that and got confused again. And I think,
that's the reason I got a very low score on our summative test. After that test, I promised to myself that I will strive hard for me to get a high score on

Now–a–days chemical effluent treatment plants use chemicals to control or neutralist he hazardous impact of pollutants produced by the industries.
Aviation and shipping industries generate power through power plants which burn fuels. Petrol and diesel emit out green house gases dangerous for
the survival on earth which damage the ozone layer that protects us from UV rays. As a result global warming has taken place which is a destroyer of
the planet earth. But again Chemistry paves the way with bio–fuels. 4. Food Security and Agriculture:
The famous green revolution to increase agricultural produce so as to ensure food security was triggered by the advent of inorganic fertilizers. Since
then fertilizers are extensively used by farmers to restore the fertility of soil in the fields. Pesticides are used to protect the crop during farming and
preserve the grains from pests, rats and mice during storage. Genetically modified seeds which are used to enhance production and earn profits through

Chemistry Effects On Environment Chemistry is "the study of composition properties, and reactions of matter particularly at the level of atoms and
molecules". (dictionary.com) There are many branches to chemistry for example organic and inorganic, physicalchemistry and environmental
chemistry.
Environmental chemistry is the study chemical process that occurs in the environment that are affected by human activities. Chemistry has many
effects on the environment good and bad; from chemicals polluting the environment to chemicals filtering the water to be safe to drink. The study of
environmental chemistry is essentially a way to help better the environment, and use methods that are less toxic to better and understand the
environment.
How chemistry has a big impact on the environment is without chemistry the environment may not thrive as well without out. The amount of impact

Chemistry In Everyday Life Essay
Have you ever wondered about the importance of Chemistry in our daily lives?. To understand why, you first need to know the definiton of Chemistry.
Chemistry is known as the branch of science that deals with the identification of the substances of which matter is composed. Their properties and the
ways in which they interact, combine, and change is the use of these processes to form new substances. As we all know, Matter is the building block of
Chemistry, Matter is a substance which occupies space, and energy. In this essay I will be comparing on how Chemistry can be used throughout our
everyday lives. Chemistry is all around us, all the little substances or manufactured materials that we see all day long is Chemistry.
An example of Chemistry being in our everyday lives is that Chemistry is everywhere in the world around us, It's in the food we eat, clothes we
wear, water we drink, medicines, air, cleaners,you name it. Chemistry is often referred to the "central science" because it connects to other sciences
such as biology, physics, and environmental science. Chemistry is made up of chemicals, and you yourself are made up of chemicals. So is your tv,

The Impact Of Chemistry On Society
Chemistry affects nearly every area of our daily life. Though we may not realize it, chemistry has significant impacts on environmental, economic,
political, and societal aspects of our society. Along with society itself, it also can greatly impact things such as technology and chemical products.
One of the most evident places that we tend to see chemistry's impact is throughout the environment. A big aspect of this that has recently became a
popular controversy is the microbeads found in several skin–care products. These tiny pieces of plastic are rinsed down the drain where they absorb
chemicals, bacteria, and other harmful substances. Eventually they make their way into our lakes and oceans. These are then essentially little poison
pellets waiting to be eaten by a fish who doesn't know any better. And as the food chain works, that poisoned fish is eaten by a bigger fish who is
later eaten by a bigger fish until eventually it ends up on your plate, last only to be eaten by you. When you then eat that fish, you're also eating all of
the toxins along with it. So, where does chemistry come into this? It's the chemists' jobs at the companies to find a solution– a face wash (or other
product) that has the same effect as the microbeads had only without the negative effect on the environment. One solution that has been proven
successful was the invention of microbeads that dissolve after a given amount of time in water. Thanks to the chemists that developed this new and

Fluoride had meanwhile gained application in toothpastes. Colgate took the lead, introducing "stannous fluoride" in 1955. Three years later, the
company launched a memorable advertising campaign with commercials in which a little girl showed her mother a "report card" from the dentist and
announced "Look, Ma! No cavities!" Within a few years, virtually all brands of toothpaste used fluoride; however, the use of fluoride in drinking water
remained controversial.
As late as 1993, in fact, the issue of fluoridation remained heated enough to spawn a study by the U.S. National Research Council. The council found
some improvement in dental health, but not as large as had been claimed by early proponents of fluoridation. Furthermore, this improvement could be
explained by reference to a number of other factors, including fluoride in toothpastes and a generally heightened awareness of dental health among the
U.S. populace.
Chlorofluorocarbons :
Another controversial application of fluorine is its use, along with chlorine and carbon, in chlorofluorocarbons. As noted above, CFCs have been used
in refrigerants and propellants; another application is as a blowing agent for polyurethane foam. This continued for several decades, but in the 1980s,

environmentalists became concerned over depletion of the ozone layer high in Earth's

The pituitary gland sees all of this activity and thinks some sort of emergency must be occurring, so it releases hormones that tell the adrenal glands
to produce adrenaline. Adrenaline is the "fight" hormone, and it makes your heart to beat faster, the breathing tubes to open up, the liver to release
sugar into the bloodstream for extra energy and your muscles to tighten up, ready for action. Because of this, after consuming a big cup of coffee your
muscles tense up, you feel excited and you can feel your heart beat increasing. Moreover, as amphetamines, caffeine also increases the levels of
dopamine, which is associated with the pleasure system of the brain, providing feelings of enjoyment and reinforcement.
Throughout the centuries, there have been many benefits brought by chemistry to our daily living. Two significant contributions made by chemistry
towards our lifestyle is the protection of our health and hygiene. The purification our water by process of chlorination, dental cleanliness from
