Climates vary and understanding that water on earth reacts to the climate is a way to understand why water can be found as both liquid and solid on earth. Included in this lesson is a video of the activity in action, and an image of a...

This lesson focuses on solids, liquids, and gases. It has several review activities and an exciting lab experiment involving ice cream to complete the lesson.

In Beautiful Chemistry, we talk about crystals, quasicrystals and glasses, which are all solids. Here, we see the molecular structure of gases and liquids.

Students observe and describe, on the molecular level, how heating and cooling affect the motion of molecules in a solid.

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

Students are given a variety of materials and asked to identify if each material as a solid, liquid or gas. They use their five senses - sight, sound, smell, texture and taste - to identify the other characteristics of each item.

Description of the factors influencing gas solubility. This site also provides other chemistry related questions. Topics include dissolving solids into liquids, concentration, and stoichiometry.

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

Provides interesting information about the three basic states of matter: solid, liquid, and gas.

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

Discover the concept that energy transfer and molecular motion cause the change in state from a solid to a liquid. Also compare state changes of water to the state changes of other substances.

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.

Learn about matter, its three states, changes of state, how matter behaves, and physical and chemical changes in matter.

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

A collection of lesson plans for helping young scholars understand atomic composition. Site uses work samples, phenomena, assessment templates, and videos to plan lessons to describe the atomic composition of simple molecules.

This interactive allows you to explore the effect that temperature and pressure have on the changes in the states of matter. You can test these variables on carbon dioxide, hydrogen and water.

Students explore how sound waves move through liquids, solids and gases in a series of simple sound energy experiments. Understanding the properties of sound and how sound waves travel helps engineers determine the best room shape and...

Students are introduced to sound energy concepts and how engineers use sound energy. Through hands-on activities and demonstrations, students examine how we know sound exists by listening to and seeing sound waves. They learn to describe...

Explains different sections of the periodic table, and how they are used.

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."

A very descriptive site that allows students to understand the different states of matter at the atomic level. Also discusses the process of phase changes and displays phase change graphs. Thermochemistry is also touched upon for high...

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...

What is a colloid? If you have made Oobleck out of corn starch and water, then you know that a colloid is a mixture that acts like a solid and a liquid at the same time. This activity helps you determine the critical factors that...
