A section in a college textbook exploring the ideal gas law in relation to molecules and in terms of moles. Learn how to calculate the variables in the ideal gas law. Also become familiar with Avogadro's number and how to use it to...

This simulation explores the relationship between the temperature of a gas, the motion of the particles in the gas and the changes in the kinetic energies of particles during collisions.

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.

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

This simulation explores the relationship between particle kinetic energies during particle collisions.

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

Did you know a balloon filled with carbon dioxide can act as an amplifier? In this activity test how sound travels through carbon dioxide molecules.

In this activity, students use pipe cleaners and foam balls to build a model of a hydrocarbon molecule. They then modify it to demonstrate the chemical reaction that happens when the hydrocarbon is burned.

Use this interactive animation to find out about whether or not gases dissolving in water.
