In this interactive lesson, students examine the quantitative relationship between chemicals in a balanced mathematical equation.

Learners study the effect that pressure has on boiling temperatures. Once a liquid has reached a full boil, additional heat does not raise the liquid’s temperature; however, pressure can vary the boiling point of a liquid. A brief quiz completes the activity.

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.

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