Three states of matter
States of matterjane
This document summarizes the three states of matter - solids, liquids, and gases. It defines their key properties and provides examples of each. Solids maintain a definite shape and size, liquids take the shape of their container but maintain a definite volume, and gases fill both the shape and size of their container. It also explains that molecules in different states behave differently, with solids having slow, close molecules, liquids having farther apart and faster molecules, and gases having very far apart and extremely fast molecules. The document concludes by noting that water is an example of a substance that can exist in all three states as ice, liquid water, and water vapor.
Text: three phases of matter
Matter exists in three phases: solids, liquids, and gases. Solids have a fixed shape and volume, with molecules packed closely together, as seen in pencil. Liquids have a fixed volume but take the shape of their container, like water. Gases easily change their shape and volume, with particles spreading apart, such as air in a balloon. The key difference between the three phases is the arrangement of molecules - closely packed in solids, somewhat free in liquids, and freely moving in gases.
Powerpoint
The document discusses the three states of matter: solids, liquids, and gases. It describes their key properties - solids have a definite shape and volume, liquids have a definite volume but take the shape of their container, and gases have no definite shape or volume. Examples of each state are provided.
Matter
This document discusses the properties and states of matter. It defines matter as anything that takes up space and has mass. Physical properties are characteristics that can be observed or measured without changing the substance, such as mass, volume, density, and state of matter (solid, liquid, gas). A mixture is a combination of two or more substances that keep their own properties, while a solution is a type of mixture where particles are evenly mixed but not easy to separate. The state that matter exists in depends on temperature and pressure - it can change states between solid, liquid and gas through physical processes like melting, freezing, boiling, evaporation and condensation that involve adding or removing heat.
Phases of matter students
The document discusses the different phases of matter - solid, liquid, gas, plasma, and Bose-Einstein condensate. Solids have a definite shape and volume, with particles tightly packed and unable to move freely. Liquids have no definite shape but a definite volume, with particles able to change position and slide past one another. Gases have no definite shape or volume, with particles in constant motion throughout their container. Plasma exists at very high temperatures and pressures and is rare, while Bose-Einstein condensates form at very low temperatures near absolute zero from cooled particles.

1. The document discusses different types of mountain formation including folded mountains formed by plate collisions at convergent boundaries, fault-block mountains formed by uplift along normal faults, and domed mountains formed by uplifting of basement rock.
2. Mountain building occurs through processes like folding, faulting, and metamorphism of rock layers as tectonic plates converge. Different mountain types result from ocean-ocean, ocean-continental, and continental-continental plate collisions.
3. After mountain building, thickened crust undergoes isostatic adjustment through regional uplift to reach a new equilibrium with the mantle.

Chemistry 3.2
The document provides an overview of solubility and solutions. It defines key terms like solvent, solute, solution, saturated solution, and discusses how temperature and concentration affect solubility. Specifically, it explains that water is called the universal solvent because it dissolves many polar solutes due to its polar nature. The document also describes how solubility, boiling point and freezing point are affected by adding solute particles that interfere with solvent molecule arrangement.
Online Solutions
This document provides information about solutions and solubility. It defines key terms like solute, solvent, saturated solution, and solubility. It explains that a solution is a homogeneous mixture of substances where one substance dissolves in another. Water is called the universal solvent because it can dissolve more substances than any other solvent. Not all substances are soluble and solubility depends on temperature, the nature of the solute and solvent, and other factors. The document also discusses different types of solutions and rates of dissolving.
Introduction to Earth Science
1) Earth science studies Earth and its place in the universe, including geology, oceanography, meteorology, and astronomy. It views Earth as an interconnected system.
2) The formation of Earth is explained by the nebular hypothesis where the solar system condensed from a giant cloud of gas and dust. As Earth formed, radioactive decay caused heating and differentiation into layers.
3) Science uses observation, experimentation and hypotheses to build theories that describe patterns in nature. Theories must withstand examination and modification.
Dissolving Sugar in Water
The document describes an experiment to test if heating water increases the amount of sugar it can dissolve. The experiment compares the amount of sugar dissolved in water heated by a kettle, tap water, and fridge water. It finds that the kettle water dissolved the most sugar, confirming that hotter water dissolves more sugar due to increased energy allowing the sugar molecules to separate and dissolve more easily in the water.
Iccs science6 solutionssuspensionsandcolloids 110212065006-phpapp01
This document discusses the classification of mixtures as solutions, suspensions, or colloids based on particle size. Solutions are homogeneous mixtures where particles are too small to scatter light or be filtered out. Suspensions are heterogeneous mixtures where particles are large enough to separate over time by settling or being filtered. Colloids have intermediate particle sizes that do not separate but can scatter light.
Preparation of Soluble Salt
The document outlines an experiment to prepare a soluble salt by reacting an acid with a metal oxide. Specifically, copper(II) oxide powder is reacted with nitric acid solution. Upon heating the reaction mixture, blue-green copper(II) nitrate solution forms. The salt solution is then cooled and filtered to obtain copper(II) nitrate crystals.
Properties of solution
The document describes a procedure where students will predict whether various samples will dissolve in water and then test their predictions. Students will mix 1/2 teaspoon of sugar, salt, mango, juice, oil, or vinegar in 1 cup of water. They will observe and describe the mixtures, identify the number of phases, solute, and solvent. Students will then filter the mixtures and observe which allow separation. The document explains that a solution forms a single, uniform phase where particles are too small to be seen individually or filtered out. It concludes that solutions are homogeneous, solute cannot be separated by filtration, and are often clear.
Solutions and Suspensions
This document defines key terms related to solutions and suspensions. It discusses solutes, solvents, solubility, rate of dissolving, saturated and unsaturated solutions, and properties of solutions and suspensions. Factors that affect solubility and rate of dissolving are also outlined, including type of solute and solvent, temperature, stirring, and surface area. Solutions are homogeneous, clear mixtures where solute particles pass through filters. Suspensions are heterogeneous, cloudy mixtures where undissolved solute particles settle out and are caught by filters.
8.1 (b) Preparation of Soluble salts
This document describes the preparation of soluble salts through various methods including neutralization reactions, titration, evaporation, crystallization, and filtration. Soluble salts can be prepared by reacting an acid with an alkali, metal, metallic oxide, or metallic carbonate. The reaction mixtures are then heated, filtered, and dried to obtain pure salt crystals. Key steps involve neutralization, evaporation to saturate and crystallize the salt, then filtration to separate and dry the pure salt product.
Properties of suspensions
Suspensions are mixtures where insoluble particles are suspended in a liquid or gas. They are created by combining an insoluble solid with a solvent, such as mixing sand and water to form a sand-water suspension. Suspensions are non-homogeneous, leave behind undissolved residue when filtered, and separate over time as the insoluble particles sink, making them unable to transmit light completely. Common examples include milo drink, coffee with milk, and salad dressing.
Concept of Evaporation.
Evaporation is the process where a liquid turns into a gas due to an increase in temperature. It is a key part of the water cycle. Children will be taught that evaporation occurs as some water molecules gain enough heat energy to escape into the air from a glass of water. A practical demonstration will show water molecules entering the air while more leave the water as long as the air is less than 100% relative humidity, transferring water to the air. Evaporation occurs daily in nature and human environments and is important in the oceans and global water cycle.
Properties of Solutions
Solutions are homogeneous mixtures where solute particles are evenly distributed throughout a solvent. A solution is formed when a solute dissolves completely in a solvent such as dissolving salt in water. Solutions are used widely in homes and industries, for example soap dissolving in water for washing and dyes dissolving in water for fabric coloring. Solutions can have solutes and solvents that are solids, liquids or gases.
Solutions
- The document discusses solutions and mixtures, explaining that a solution is a type of mixture where a solid dissolves evenly into a liquid. It provides examples like sugar dissolving in water to form a solution.
- Key properties of solutions are discussed, such as solids breaking apart into particles when dissolved and how solutions can be separated through evaporation.
- An activity is described where students use a diagram to identify items that do or do not dissolve in water to form solutions.
Colloidal disp[1] ppt [compatibility mode]
Colloids can be classified based on particle size as molecular, colloidal, or coarse dispersions. Colloidal dispersions have particle sizes between 1-500 nm. Colloids can also be classified as lyophilic, lyophobic, or association colloids based on particle interactions. Lyophilic particles are solvent-loving, lyophobic are solvent-hating, and association colloids form micelles. Purification of colloids can be done using dialysis, which separates colloidal particles from dissolved impurities based on size, or electrodialysis, which uses an electric field to enhance impurity removal.
Mixtures powerpoint
A mixture is a combination of two or more substances that are physically mixed together without undergoing a chemical reaction. Mixtures can be heterogeneous, with each component clearly visible, or homogeneous, where the components are evenly distributed and not visible individually. Mixtures differ from compounds in that their components can be separated by physical means and do not have a fixed composition.

Colloids
This document discusses colloids, including their definition and classification. Colloids can be classified into different types of mixtures including sols, foams, emulsions, and gels. Sols are solid particles dispersed in a liquid, foams contain gas pockets in a liquid or solid, emulsions involve two immiscible liquids, and gels contain molecules of a liquid dispersed within a solid matrix. The document also provides examples of each type of colloidal mixture and discusses reversible versus irreversible colloid formation.

Cooperative learning
Cooperative learning is an approach to organizing classroom activities into academic and social learning experiences. It differs from group work, and it has been described as "structuring positive interdependence.Students must work in groups to complete tasks collectively toward academic goals. Unlike individual learning, which can be competitive in nature, students learning cooperatively capitalize on one another’s resources and skills (asking one another for information, evaluating one another’s ideas, monitoring one another’s work, etc.).Furthermore, the teacher's role changes from giving information to facilitating students' learning. <http: />
Cooperative learning
The document discusses the structure and properties of water molecules. It explains that a water molecule is made up of two hydrogen atoms bonded to one oxygen atom at an angle of 105 degrees, giving the molecule a slight positive and negative charge. This allows hydrogen bonds to form between water molecules, giving water its unique liquid properties even at room temperature. The document also describes how water can absorb large amounts of heat without much change in temperature, and how its heat capacity helps regulate temperatures in the environment.

Matter Around Us
A PPT based on the Matter Around us. With Reference to NCERT book Class 9 and Obviously with GOOGLE!!!! (Nothings possible without a little bit of googling!)
Webquest
The document describes a science webquest with multiple tasks. The first task involves reading websites about the states of matter and taking quizzes. It provides the scores from the quizzes. The second task involves answering questions about the states of matter. The third task has the student visit a website about solids, liquids and gases. The fourth task has the student observe reversible and irreversible changes. It also describes an activity where different amounts of salt are added to colored water to demonstrate how salt makes water denser.
Matter
This document discusses matter and its properties. It defines the three common states of matter as solid, liquid, and gas. Solids have a definite shape and volume, with particles that are close together. Liquids take the shape of their container but have a definite volume, and their particles can move past one another. Gases spread out to fill their container and do not have a definite volume. The document also distinguishes between physical and chemical properties, and physical and chemical changes. Scientists use tools like balances and measuring cups to measure the mass and volume of matter.
Physical properties kinetic theory me3
Kinetic theory states that all particles of matter are constantly in motion. The state of a substance, such as solid, liquid, or gas, depends on factors like temperature and volume. When energy is added to a substance, its temperature or state can change. Density is a measure of the amount of matter present in a given volume and relates to kinetic theory by describing how closely packed particles are. Physical properties like viscosity, solubility, and malleability also depend on particle motion and interaction as described by kinetic theory.
Particle model
The document discusses the particle theory and the three types of particles: solid, liquid, and gas. It describes how the particles in solids are tightly packed and vibrating, while liquid particles have more space to slide past each other, and gas particles have the most space and move freely in random directions. It also examines how heating and cooling causes materials to expand and contract as the energy and movement of their particles changes.
Matter printouts
This document outlines the learning outcomes and content covered in a Year 9 unit on matter and atoms.

Phenomics assisted breeding in crop improvement
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
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.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.

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.
