properties of materials II
Materials have different properties depending on their flexibility, rigidity, and water resistance. Flexible materials like rubber bands and bicycle tubes can be easily bent or stretched, while rigid materials such as wood, stone, and scales cannot. Waterproof materials do not allow water to pass through them, protecting things from getting wet. Examples include raincoats and aluminum foil. Students are asked to match material types and answer questions about definitions of flexible, rigid, and waterproof.
Origin of names of elements
Elements were originally named after places, countries, continents, scientists, planets, and satellites. For example, polonium was named after Poland, curium was named after Marie Curie, and chromium comes from the Greek word for color. Element symbols are short representations of their names, with the first letter used for many elements like C for carbon and O for oxygen. Some elements use multiple letters from their name like Ca for calcium. A few element symbols come from their Latin names, such as Na for sodium and Fe for iron. Common elements used in daily life include iron, oxygen, carbon, aluminum, copper, nickel, gold, and silver.
Habitats for plants and animals
Habitats for Plants and Animals discusses different environments and how they provide habitats for various species. It defines key terms like habitat, environment, and ecosystem. It describes different land and water habitats like rainforests, deserts, forests, tundra, oceans, rivers and ponds. The document also covers animal adaptations like camouflage, migration, hibernation and how plants and animals depend on each other through food chains and ecosystems.
1 hrly gs ch 02 earth movement
Earth rotates on its axis once every 24 hours, causing day and night. It also revolves around the sun once every 365.25 days, causing seasons. Earth's axis is tilted at an angle of 66.5 degrees, which causes the length of days and nights to vary throughout the year and creates different seasons in each hemisphere simultaneously. The moon's gravitational pull causes high and low ocean tides daily as well as solar and lunar eclipses periodically as the moon passes between the earth and sun or earth passes between the moon and sun.
Force
This document provides information about force and motion. It defines a force as a push or pull and notes that all forces have magnitude and direction. It then gives several examples of the effects of different forces, such as an arrow hitting a target. The document discusses that a force can change an object's shape, size, and motion. It also defines types of motion, speed, velocity, acceleration, and summarizes Newton's Three Laws of Motion.
Forces
This document discusses different types of forces. It explains that gravity, the ground, air, and your own body exert forces on you at all times. Forces can cause objects to move, change speed or direction. Gravity pulls objects down, while surfaces push up. Friction opposes motion and can slow or stop objects. Net force is calculated by adding or subtracting different forces on an object. Balanced forces result in no motion, while unbalanced forces cause motion.
Vertebrates and invertebrates
Vertebrates are animals with backbones and include fish, amphibians, reptiles, birds, and mammals. Invertebrates lack backbones and make up over 98% of animal species, including sponges, jellyfish, worms, starfish, insects, and others. Vertebrates have evolved to live on land and in air and water, while invertebrates mainly live in water and on land without mobility. The document then provides more details on characteristics of different vertebrate and invertebrate groups.
Lab tools powerpoint presentation
This document introduces various lab tools that will be used in a science class this year, including safety goggles to protect eyes, test tubes for heating liquids, microscopes for viewing small objects, beakers for moving, heating or storing liquids, thermometers for measuring temperature, stop watches for timing experiments, funnels for pouring liquids, droppers for precise liquid amounts, graduated cylinders for accurate volume measurements, digital balances for weighing objects, hand lenses for magnification, and conical flasks as another container for liquids.
Parts of the plants and their functions
The document discusses the main parts and functions of plants. It explains that most plants have three main parts: roots, stems, and leaves. The roots hold the plant in the soil and absorb water and minerals. The stem carries water and minerals from the roots to the leaves, supports the plant, and can be thick like a tree trunk, thin like a bush, or soft like grass. The leaves make food for the plant using sunlight, air, and water. Flowers are the reproductive part where seeds form, and fruit protects the seeds so new plants can grow.
Parts of a plant ppt
The document discusses the main parts of a plant including seeds, roots, stems, leaves and flowers. It describes the function of each part, with seeds growing into new plants, roots absorbing water and minerals, stems carrying water and sugar, leaves producing food, and flowers making fruit or being pretty blossoms. It also lists examples of edible plant parts like roots, stems, leaves, flowers, fruits and seeds.
The needs of a plant!
Plants need water, soil, space, sunlight, and air to survive and grow healthily. Water and minerals from the soil are absorbed by the roots and transported throughout the plant. Sunlight provides energy for photosynthesis to convert water and carbon dioxide into oxygen and food. Plants also require adequate space to spread their roots and access nutrients from the soil. Air supplies the oxygen necessary for plant respiration. Without these basic requirements, plants are unable to grow.
Volumelab
This document describes a volume lab with four parts. Part A has students measure the number of drops in 1 mL of water using an eyedropper and graduated cylinder. Part B uses water displacement to find the volume of three marbles. Part C uses a formula to calculate the volume of a box. Part D mixes colored water in test tubes, measuring amounts poured between tubes to create a rainbow of colors. Safety is discussed at the end.
Learning theories PPP
This document provides an overview of learning theories as they relate to adult education. It discusses the two major categories of learning theories - behaviorist/connectionist theories and cognitive/gestalt theories. Specific theories by B.F. Skinner and Edward Tolman are described in more detail. Skinner's operant conditioning theory focuses on how behaviors are shaped through reinforcement or punishment. Tolman's cognitive theory suggests that learning involves developing a mental map and occurs even without reinforcement. The document also discusses how these theories can be applied to adult education programs and analyzes examples of applying Skinner and Tolman's theories to training phlebotomists.

The document discusses several theories of cognitive development and their relevance to teaching, including behaviorism, Piaget's theory of cognitive development, and Vygotsky's sociocultural theory. It notes that behaviorism sees learning as response to external stimuli and conditioning, while Piaget believed development occurs in stages linked to maturation. Vygotsky argued learning is social and occurs through scaffolding within a child's zone of proximal development with help from others. The document concludes that teachers should consider multiple theories to create effective learning environments tailored to different students and contexts, as no single approach fits all situations.

Implication of cognitive development in teaching and learning
This document discusses Piaget's and Vygotsky's theories of cognitive development and their implications for teaching practices. Piaget's theories suggest that teachers should use concrete examples, hands-on activities, and familiar contexts tailored to students' developmental levels. For pre-operational children, instruction should be explicit, involve interactions, and provide a variety of experiences. Concrete operational children benefit from continued hands-on learning and logical problem-solving. Formal operational students can explore concepts and hypotheses. Vygotsky's zone of proximal development theory implies assessment and instruction should start at students' current ability levels and provide support and motivation to progress further. Teachers should encourage collaboration and apply lessons to real-world experiences.
Learning theories and its implication to education
The document discusses different learning theories and their implications for education. It states that people learn in different ways so teachers must use varied teaching strategies. It also emphasizes that developing good study habits through supervision and frequent review is important. Finally, it argues that the real impact of learning theories is seen in whether individuals become well-developed socially, emotionally, politically, economically, and culturally.

Cognitivist learning theory focuses on how people actively construct knowledge through thinking rather than passively receiving it. It differs from behaviorism in that it emphasizes the role of cognitive processes like problem solving, memory, and language processing in learning. Key contributors to cognitivism developed theories about how knowledge is organized and processed in the brain, such as dual coding theory, schema theory, Bloom's taxonomy of cognitive domains. Cognitivism supports the use of interactive tools and visual aids to engage students in applying and building upon their existing knowledge through higher-order thinking.
Learning theories 1
1) The document outlines several theories of learning including classical conditioning by Pavlov involving associating a neutral stimulus with a reflex, operant conditioning by Skinner involving reinforcement of behaviors, social learning by Bandura involving observational learning, and insightful learning involving problem solving.
2) Clinical applications of these theories include the development of fears through classical conditioning, using reinforcement schedules in token economies for behavior modification, and making diagnoses through selectively encoding, comparing, and combining information.
3) Other concepts discussed include latent learning, Vygotsky's zone of proximal development involving learning with guidance, and Lewin's field theory emphasizing the interaction between individuals and their environment in influencing behavior.

This document outlines Bill Aulet's presentation on improving entrepreneurship education. It discusses defining entrepreneurship, assessing student needs through personas, and designing a comprehensive curriculum with modular "tiles" addressing each persona's needs. The goal is to make entrepreneurship education more rigorous, practical, and tailored through open-source sharing of best practices. This will help address the increasing demand for high-quality entrepreneurship training.Can We Assess Creativity?
With the explosion of the maker movement, schools are beginning to embrace creativity. However, what does this mean for assessment? Should we assess the creative process? Should we assess the finished product? Does assessing creativity actually make kids more risk-averse? In this workshop we explore what it means to assess both the creative process and the creative product without leading to risk aversion.

Thermal energy is the energy of moving particles that causes heat. Heat is the transfer of thermal energy between objects when they are at different temperatures. The document discusses conductors and insulators - materials that easily allow heat to pass through them are conductors like metals and materials that do not are insulators like rubber, wood, and paper. Common examples of conductors and insulators are provided.
Air and water resistance
The document discusses different forces exerted by water and air. There are two main forces of water: upthrust force, which causes objects to float, and water resistance, which pushes against moving objects in water. Air also exerts forces, including air resistance, which slows down moving objects by pushing against them, with larger objects experiencing greater resistance. Air resistance can be useful, as seen with parachutes which use the force of air to slow a falling object.
Balanced unbalanced ,gravity ,friction
1) Forces cause objects to move or change their motion. Applying an unbalanced force makes an object start moving, while balanced or cancelled out forces will not cause motion.
2) Friction is a type of force that opposes motion when two surfaces are touching, causing moving objects to slow down and stop. The amount of friction depends on the surfaces and how rough or smooth they are.
3) Mass and gravity determine an object's weight, with heavier objects having greater weight. Weight can be measured using a force meter or spring scale.
Magnetic and non magnetic
The document discusses magnetic and non-magnetic materials. Magnetic materials include metals like iron, nickel, cobalt and steel that are attracted to magnets. Non-magnetic materials include aluminum, silver, gold, paper, glass, plastic, rubber and wood that are not attracted to magnets. It provides examples of different objects and whether they are magnetic or non-magnetic when tested with a magnet.
Magnet use
To safely handle magnets, wear protective eyewear and gloves to avoid injury from breaking or flying pieces. Handle magnets gently by slowly bringing them together and avoiding dropping or banging them, which can reduce their strength. Store magnets away from devices, tapes, cards, and screens where magnetic fields can cause damage or distortion. Also, keep magnets dry and do not heat them.
Magnet type + story
Magnets have been known since ancient times when a shepherd named Magnus discovered that an unusual black rock had the power to pull iron objects like his staff and sandal nails towards it. This became known as the first recorded discovery of a magnet. Different types of magnets exist, with some able to attract or repel other magnets depending on which poles (north or south) are placed close together. Magnets have been studied for centuries but still hold mysterious properties about the forces they exert.
Magnet 3
Magnets are made of iron, nickel, cobalt, or steel. To preserve a bar magnet long term, you should store it with another magnet to maintain its magnetic field. When a magnet breaks, its magnetic field also breaks into smaller fields in each broken piece. An electromagnet generates a magnetic field through a coil of wire when electric current passes through; placing an iron core inside the coil strengthens the magnetic field. Materials can be magnetic, like iron, cobalt, and nickel, or non-magnetic, like aluminum, copper, glass, plastic, and wood.
Magnet 2
The document discusses the properties of iron and magnets at the particle level. It asks questions about what iron particles look like, how iron is attracted to magnets, what magnets are made of, and how to preserve a bar magnet long-term. It prompts the reader to draw diagrams of magnetic fields with arrows and labels to illustrate the alignment of iron particles when brought near a magnet.
Series and parallel
The document discusses series and parallel circuits. It provides examples of series circuits with one path and defines that if one light bulb is removed, the circuit is open and other bulbs will not light. Parallel circuits are defined as having more than one path, and if one light bulb is removed, the current passes through another path and the other bulb will still light. The document draws examples of both series and parallel circuits.
Safety rules
This document provides safety tips for handling electricity, advising to not play with electric sockets or plugs, not to touch electricity with wet hands, and to avoid poking fingers or other objects into electric sockets, toasters, or other appliances.
Conductor and insulator
This document discusses series and parallel circuits and the properties of conductors and insulators. It explains that in a series circuit, if one bulb is removed the other bulb will not light, while in a parallel circuit the other bulbs will still light if one is removed. It provides examples of materials that are conductors, like silver, copper and aluminum, and insulators, like plastic, rubber and glass. It then has questions to determine if examples provided are conductors or insulators.
Circuit (symbols,dimmer and brighter)
This document discusses the basics of electricity and electrical circuits. It explains that electricity is the flow of electric charges through a wire, just as water flows through a river. An electrical circuit needs three main components - a power source like a battery, a load such as a light bulb, and wires or other connectors to complete the circuit. It also discusses concepts like open versus closed circuits, and how changing components like batteries or bulbs affects brightness. Symbols are introduced for common circuit elements. Worksheets are included to have the reader draw sample circuits.
Atom,static electricity
The document discusses the basics of static electricity and atoms. It explains that atoms are made up of positively and negatively charged particles that attract or repel depending on their charges. Static electricity occurs when objects come into contact and transfer electrons, resulting in an imbalance of charges. Examples given include rubbing a balloon or ruler to build up an excess of electrons, causing it to stick to other surfaces. Lightning is also described as a large-scale discharge of built up static charges between storm clouds and the ground.
Reversible and irreversible change
The document discusses reversible and irreversible changes. Reversible changes can go forward and backward, such as folding paper or melting butter. Irreversible changes cannot go backward, like burning wood or rusting iron. Examples are provided of changes that are reversible, like freezing orange juice or dissolving salt in water, and those that are irreversible, including burning a matchstick or toasting bread.
Reversible and Irreversible changes
This document discusses the differences between physical and chemical changes and provides examples of evidence of irreversible chemical changes. Specifically, it notes that physical changes are reversible while chemical changes are irreversible. It then lists four main types of evidence that can indicate an irreversible chemical change has occurred: 1) a change in color, 2) a change in scent, 3) the presence of bubbles or fizzing, and 4) heat being released or absorbed during the change. Examples like iron rusting and silver tarnishing are given as illustrations of changes in color, while toasting marshmallows represents a change in scent.
Food pyramid wiki
The food pyramid outlines the major food groups including carbohydrates, vitamins and minerals, protein, and oils. It recommends filling your plate with fruits, vegetables, dairy, and meat to create a balanced meal and get the necessary nutrients. A balanced meal incorporates foods from all the major food groups.
Teeth wiki
There are three main types of teeth: incisors, canines, and molars. Incisors are flat teeth located at the front of the mouth that cut food. Canines are sharp, pointed teeth on the sides of the mouth after the incisors that hold and tear food. Molars are flat, wide teeth located at the back of the mouth that grind and chew food. Humans have two sets of teeth, milk (baby) teeth and permanent teeth. Milk teeth number 20 total while permanent teeth number 32 total. Bacteria in the mouth feed on sugar from leftover food and produce acid that causes tooth decay if plaque is not removed by brushing.
Matter
Matter is anything that has mass and takes up space. There are three main states of matter: solids, liquids, and gases. The state that matter exists in depends on how closely or loosely packed the particles are and the strength of attraction between the particles. Solids have a definite shape and volume, liquids have a definite volume but take the shape of their container, and gases have indefinite shapes and volumes. Matter can change between states, such as ice melting into water when heat is applied, changing the phase from solid to liquid.
Teeth 2
This document describes the different types of teeth and their functions. It discusses the four types of teeth: incisors, which cut food; canines, which tear and hold food; premolars, which have a grinding function; and molars, which grind and chew food. It also notes that humans have two sets of teeth - milk (primary) teeth when young, which are later replaced by permanent adult teeth starting around age 6 or 7 years old.
Teeth 1
Teeth have the function of breaking down food into pieces small enough to swallow. There are different types of teeth suited to specific functions, such as incisors for biting, canines for tearing, and premolars and molars for grinding food. Teeth break down food through biting, tearing, and grinding motions.

Authoring a personal GPT for your research and practice: How we created the Q...
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.

Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.

The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

Candidate young stellar objects in the S-cluster: Kinematic analysis of a sub...
Context. The observation of several L-band emission sources in the S cluster has led to a rich discussion of their nature. However, a definitive answer to the classification of the dusty objects requires an explanation for the detection of compact Doppler-shifted Brγ emission. The ionized hydrogen in combination with the observation of mid-infrared L-band continuum emission suggests that most of these sources are embedded in a dusty envelope. These embedded sources are part of the S-cluster, and their relationship to the S-stars is still under debate. To date, the question of the origin of these two populations has been vague, although all explanations favor migration processes for the individual cluster members. Aims. This work revisits the S-cluster and its dusty members orbiting the supermassive black hole SgrA* on bound Keplerian orbits from a kinematic perspective. The aim is to explore the Keplerian parameters for patterns that might imply a nonrandom distribution of the sample. Additionally, various analytical aspects are considered to address the nature of the dusty sources. Methods. Based on the photometric analysis, we estimated the individual H−K and K−L colors for the source sample and compared the results to known cluster members. The classification revealed a noticeable contrast between the S-stars and the dusty sources. To fit the flux-density distribution, we utilized the radiative transfer code HYPERION and implemented a young stellar object Class I model. We obtained the position angle from the Keplerian fit results; additionally, we analyzed the distribution of the inclinations and the longitudes of the ascending node. Results. The colors of the dusty sources suggest a stellar nature consistent with the spectral energy distribution in the near and midinfrared domains. Furthermore, the evaporation timescales of dusty and gaseous clumps in the vicinity of SgrA* are much shorter ( 2yr) than the epochs covered by the observations (≈15yr). In addition to the strong evidence for the stellar classification of the D-sources, we also find a clear disk-like pattern following the arrangements of S-stars proposed in the literature. Furthermore, we find a global intrinsic inclination for all dusty sources of 60 ± 20◦, implying a common formation process. Conclusions. The pattern of the dusty sources manifested in the distribution of the position angles, inclinations, and longitudes of the ascending node strongly suggests two different scenarios: the main-sequence stars and the dusty stellar S-cluster sources share a common formation history or migrated with a similar formation channel in the vicinity of SgrA*. Alternatively, the gravitational influence of SgrA* in combination with a massive perturber, such as a putative intermediate mass black hole in the IRS 13 cluster, forces the dusty objects and S-stars to follow a particular orbital arrangement. Key words. stars: black holes– stars: formation– Galaxy: center– galaxies: star formation
