In this interactive object, the learner practices identifying charges on ions.
Solubility of Ionic Compounds in Water
By Dr. Miriam Douglass, Dr. Martin McClinton
Learners view movie clips to determine the solubility of two ionic compounds. They also examine a solubility chart and predict the solubility of compounds.
Gas Volume vs. Pressure (Boyle's Law)
Boyle's Law states that gas volume varies inversely with the pressure at constant temperature and is described by the equation PV = constant. An example of a sample of gas at two conditions of P and V is used to illustrate the law.

In this interactive lesson, students examine the quantitative relationship between chemicals in a balanced mathematical equation.
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Learners assign oxidation numbers to atoms in neutral compounds and in polyatomic ions. Six examples are worked through in detail, and three problems are provided.
Using an Indicator
By Janet Braun, Barbara Anderegg
