Learners use the coefficients in a balanced equation to develop the mole ratios of reactants and products involved in the reaction. Five interactive examples illustrate the method, and students test their knowledge by working four problems.

Students read an explanation of chemical formulas in this animated activity. A quiz completes the object.

Learners examine a table containing the names of common cations and anions.

In this animated activity, learners examine what gases are composed of and how their particles interact. They also consider several assumptions that form the basis for the Kinetic Theory of Gases.

Students read brief descriptions of atoms, molecules, elements, and compounds, and complete a matching exercise that pictures these particles and molecules as pieces of taffy.

Students read about the basic organization and structure of the periodic table of elements. By clicking on the symbol, they can read that element's atomic number and weight. In an exercise, students identify elements as belonging to a group, a period, or neither.

Students read an introduction to the lab equipment used to contain and dispense chemicals. A quiz completes the activity.

Students practice identifying common elements from the periodic table by name or symbol.

In this screencast we are introduced to the lab equipment used to contain and dispense chemicals.
