Learn about the increase or decrease of size of an object due to thermal expansion in this college textbook section. Understand how to calculate linear and volume expansion of an object as well as thermal stress. Section also includes...

This site helps students construct a model of the arrangement of water molecules when present as solid, liquid or gas. Includes background information, lesson plans, links to standards and assessment ideas.

This lesson introduces students to the important concept of density. The focus is on the more easily understood densities of solids, but students can also explore the densities of liquids and gases. Students devise methods to determine...

Many substances are actually mixtures of different things. For example, milk, which looks like it is one substance, is actually a mixture of many different solids and liquids. Chromatography is a technique that is used to separate...

Water can exist in three different phases. This still collage produced for Teachers' Domain features examples of water in liquid, solid, and gas states.

Learn what a Buchner funnel is, how it works to filter solids from liquids, and some of its applications.

This lesson focuses on the states of matter: solids, liquids, and gases. It also discusses the Kinetic Theory of Matter, Thermodynamics, Triple point, Phase Change Graphs and the Heating Curve of Water. It provideds adrawing of a heating...

A Quantitative Transfer simply means that all the material to be transfered from one place to another must make the trip, down to the last particle. Use this site to find out how to correctly transfer a solid and a liquid.

Learn about how greater temperatures increase the solubility of solids in liquids due to a greater velocity of the particles. A chart helps explain the solubility rate of glucose at different temperatures. Also, find links to textbook...

In this lesson students are required to observe a simple model of the water cycle constructed of sand and ice in a plastic shoe box.

Tells the story of how Archimedes discovered the Archimedes Principle and his water displacement method for determining the volume and density of an object. Provides an explanation and several examples of how it is done.

Did you know the ancient Greeks first identified the three states of matter? Read about how the molecules differ in solids, liquids, gases, and plasma. View photographs and watch how the molecules move in each state. If you're really...

An eBook containing information regarding states of matter as it applies to celestial bodies and a universe.

Join a group of middle-school students on a visit to a laboratory at the Massachusetts Institute of Technology, where they experiment with "mystery mud" and learn about the relationships between magnetism, particle motion, and changes in...

Students will witness a fascinating chemical reaction and learn how to identify when a reaction has occurred by combining simple ingredients.

Students observe a molecular dance of bursting colors through exploring states of matter and learning that materials can be characterize by how they respond to water.

Students characterize materials by their state of matter and then combined materials to create a piece of colorful, tie dye-esque paper.

The concepts of melting point and freezing point are explained on this site.

This tutorial helps students understand the Kinetic Theory, which explains the effects of temperature and pressure on matter as it goes through phase changes.

This activity explores the property of density in a variety of liquids and solids.

Learn about the three phases of matter, and how the addition and removal of thermal energy (also known as heat) affects them.

This article tells what specific gravity and how to compute the specific gravity for solids, liquids, and gases.

The question: "What would the triple point of water truly look like?" is discussed and explained. The phases of matter are described.

What is poisoning and how does it affect a person's body? Find the answers to these questions, and learn how to react to poisoning in an emergency situation. Website contents were taken from the pages of the "St. John First Aid Manual."
