A core principle in all sciences is that atoms and molecules are in constant motion. This motion is determined by the amount of energy in the substance. Substances with little energy have slow moving molecules and are solids, and substances with a lot of energy have fast moving molecules and are gases.
This PowerPoint is designed to teach students the relationship between energy and the motion of molecules. Included are 22 slides, 16 of which have questions that will guide your students through this learning process.
Designed primarily for middle school students, this PowerPoint could also be used for younger and older students.
