The document discusses the properties and types of matter, including the three states of matter (solid, liquid, gas), mixtures and their separation, physical and chemical properties, physical and chemical changes, and the laws of conservation of mass, definite proportions, and multiple proportions as they relate to matter and chemical reactions. Elements are pure substances that cannot be broken down further, while compounds are combinations of two or more elements that have properties different from their component elements. Matter is anything that has mass and takes up space.
Matter can exist in three states - solid, liquid, and gas. Examples of solids are ice and diamonds; examples of liquids are water and mercury. Gases include water vapor and oxygen. Characteristic properties like boiling point and melting point are used to identify substances and do not change, even if the substance changes state. Physical changes alter the substance's form through processes like melting or crushing, but do not change its chemical makeup. Chemical changes form new substances through chemical reactions.

Matter is anything that occupies space and has mass. It can be classified as elements, compounds, or mixtures. Elements are substances that cannot be decomposed, compounds are formed when two or more elements chemically combine, and mixtures maintain the properties of their components. Matter can exist in solid, liquid, or gas states and sometimes as plasma under special conditions. Its state changes with the addition of energy. A substance undergoes physical changes when its appearance changes but not its composition, and chemical changes when its composition changes through chemical reactions.

Chemistry is the study of matter and its properties. The document outlines the core topics covered in a chemistry course including atomic structure, the periodic table, bonding, nomenclature, chemical reactions, stoichiometry, gas laws, solutions, acids and bases, and thermochemistry. It defines matter as anything that has mass and takes up space, and describes the two main types of matter as pure substances and mixtures. Pure substances are either elements, which consist of only one type of atom, or compounds, made of two or more bonded elements. Mixtures can be solutions, mechanical mixtures, suspensions, or colloids depending on whether the parts are evenly mixed or separated.

This document provides an overview of key concepts in matter and changes of state from a chemistry textbook. It defines matter as anything that has mass and takes up space. Properties of matter are classified as either extensive, depending on amount, or intensive, not depending on amount. The three main states of matter are solids, liquids, and gases. Mixtures can be either heterogeneous, with unevenly distributed components, or homogeneous, with uniformly distributed components. During chemical changes, the composition of reactants changes as they are converted into different products.
This document defines key concepts about the three states of matter, physical and chemical properties, and phase changes. It also discusses mixtures, elements, compounds, and the laws of definite and multiple proportions. The periodic table is introduced as organizing all elements. Methods for separating heterogeneous mixtures include filtration, distillation, crystallization, sublimation, and chromatography.
This document discusses the differences between pure substances and mixtures. Pure substances are either elements or compounds, while mixtures contain two or more substances mixed together. Compounds are formed by a chemical change and can be broken down, while elements are simplest forms that cannot be broken down further. Mixtures can be either homogeneous, with substances evenly mixed together like solutions, or heterogeneous with distinct parts like suspensions. Common separation methods for mixtures include distillation, filtration, and evaporation which separate substances based on properties like boiling points or particle size. Chemical changes can be identified by a change in color, production of a gas, or formation of a precipitate.
Water is an example of matter that is made of hydrogen and oxygen atoms. It has no smell, color, or taste and can change between solid, liquid, and gas states through melting, freezing, evaporating, and condensing. A pure substance consists of only one component while a mixture is made of two or more substances that can be either heterogeneous, where the parts can be seen separately, or homogeneous, where the parts cannot be seen individually. Waste comes in organic, recyclable, and non-recyclable forms.
Matter can be summarized as follows:
Matter is anything that occupies space and has mass. It exists in three states - solid, liquid, and gas. Matter changes between these states through processes like fusion, condensation, evaporation, and solidification. Matter can be classified as pure substances or mixtures. Mixtures contain more than one substance and can be separated using methods like evaporation, distillation, filtration, and decantation. Changes to matter can be physical, changing its shape or size, or chemical, changing its composition.

Matter is anything that takes up space and has mass, including invisible substances. It is made of elements, the basic building blocks of atoms, and compounds, which are combinations of two or more elements chemically bonded together. Matter can also exist as mixtures of elements and compounds mixed together without chemical bonds. Physical changes alter the state of matter between solid, liquid and gas, while chemical changes create new substances through chemical reactions.

Physical changes alter the state of matter between solid, liquid and gas, while chemical changes create new substances through chemical reactions.
Matter is anything that takes up space in the universe. It has general properties like mass and volume, and specific properties like color and density. There are two types of changes in matter: physical changes, which do not change the mass or type of matter, like changes in shape or state; and chemical changes, which produce new substances when two or more react. Pure substances are made of one type of matter, while mixtures contain different types that can sometimes be separated.
Matter is everything that occupies space in the universe. It has two fundamental properties - mass, which is a measure of the quantity of matter, and volume, which is the space occupied. Matter can exist in three states - solid, liquid, and gas. It also has specific properties like color and density that differentiate types of matter. Matter undergoes physical changes that alter its shape or state without changing its composition, like melting, freezing, and expansion/contraction. Chemical changes occur during chemical reactions and result in new substances. Pure substances are made of only one type of matter, while mixtures and solutions combine multiple types of matter without chemical bonding.
Matter exists in three states - solid, liquid, and gas. 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 and expand to fill any space. Physical changes alter a substance's shape or state without changing its chemical makeup, like freezing, bending, or the water cycle. Chemical changes produce new substances through processes like burning or exposure to air. Mixtures can be either heterogeneous, where the components are visibly separated, or homogeneous, where the components are evenly distributed and not visible. Natural materials come from plants, animals or minerals while manufactured materials are human-made. It is important to reduce waste, reuse materials, and
This document defines and provides examples of different types of matter including pure substances, mixtures, elements, compounds, and properties. It explains that a pure substance is homogeneous and cannot be separated further, while a mixture contains two or more substances that can be separated. Mixtures are either heterogeneous, with a varying composition, or homogeneous, with an even composition throughout. Elements contain one type of atom, while compounds contain more than one type of element. Chemical and physical properties and changes in states of matter are also defined.

The document provides an overview of classifying and studying matter. It defines matter as anything having mass and volume. It discusses the basic units of matter being atoms and classifies matter as either pure substances (elements or compounds) or mixtures. Elements contain only one type of atom, while compounds are made of two or more different elements that are chemically combined. Mixtures are combinations of substances that are not chemically combined and can be separated physically. Mixtures are either homogeneous, appearing uniform throughout, or heterogeneous, visibly different throughout. Examples and diagrams are provided to illustrate these key concepts.
Matter can be either pure substances or mixtures. Pure substances, like elements and compounds, have consistent properties and a uniform composition throughout. Mixtures, on the other hand, are combinations of two or more substances that are physically blended but retain their individual properties and can be separated. Mixtures can be either homogeneous, where the components are uniformly distributed, or heterogeneous, where the components can be visually distinguished. Common examples of mixtures include saltwater, air, and trail mix.
Matter is classified into pure substances and mixtures. Pure substances are either elements, which are substances that cannot be broken down further, or compounds, which are made of two or more elements chemically bonded together. Mixtures contain two or more substances that are not chemically combined and can be separated physically.

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.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...Leonel Morgado
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.

Immersive Learning That Works: Research Grounding and Paths ForwardLeonel Morgado
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.
The cost of acquiring information by natural selectionCarl Bergstrom
This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:

Classifying Matter.pptx
1.
2. Matter is anything that has mass and takes
up space.
Mass is a measure of the amount of matter in
an object and is measured in units such as
grams and kilograms.
Volume is a measure of the amount of space an
object takes up, and is measured in mL, L, or
cubic units for solids.
All matter is made up of tiny particles.
All matter can be classified as a pure
substance or a mixture.
3.
4. Pure substances have only one type of
particle.
The properties of a pure substance are
always the same.
› Example: colour, boiling point, melting point
5. 1. Element: only one type of particle
Example- Carbon, Hydrogen, Nitrogen (anything on
the periodic table!)
6. 2. Compounds: made from 2 or more elements
that are chemically combined in a fixed ratio.
Examples- sugar, water, carbon dioxide
7. Two or more substance that are not
chemically combined.
Do not have a fixed composition.
Do not have constant properties.
Example- milk, coffee, air
8.
9. Mixtures are a type of matter that are not
pure substances.
There are 3 types of mixtures:
10. The different substances that make up the
mixture are visible.
Also called heterogeneous mixtures.
Example: soil, soup.
11. The different particles that make up the
mixture are not visible.
Will not eventually settle out.
Also called a homogenous mixture.
Example: coffee, tea
12. The tiny particles of one substance are held
within another to create a cloudy mixture.
Can be separated.
Example: tomato juice
15. Chemical property: can only be observed
when a chemical change takes place
› Include flammability, gas being produced, etc.
Physical property: characteristics of a
substance that can be observed without a
change taking place
› Include color, shape, texture
