Start this mini unit on matter out by demonstrating how food coloring behaves when placed in cold and in hot water. Then have the class experiment with warm water and soap film. Pupils will learn that an increase in thermal energy also...

Spangler invites a teacher in for this segment. She has developed some amazing demonstrations which use liquid nitrogen for elementary schoolers. She drops inflated balloons into a bowl of liquid nitrogen and the results are quite...

In this episode of "Steve Spangler Science" videos, the gas produced by the sublimation of carbon dioxide dry ice creates a nice, fluffy cushion in a bowl of water. Since it is less dense than a soap bubble and cool enough to keep it...

Display the arrangement of molecules in solids, liquids, and gases. Demonstrate how the addition of heat energy results in greater molecular motion and therefore a change of phase. Give examples of heat conductors and insulators, and...

Part of a longer video created by Disney, this segment opens with a history of the telescope and microscope. This old-fashioned video is a sufficient introduction to the topic of atoms. The animations are antiquated, but they are still...

Middle school chemists visit interactive websites in order to discover what happens to molecular motion when heat is added to matter. They conduct an experiment that demonstrates the expansion of matter with the addition of heat. A lab...

Students compare the freezing temperature of two substances by conducting an experiment to freeze liquid ice cream. They vary the amount of salt used in the ice cubes during the freezing procedure to determine the change in the...

Fourth graders define the states of matter and their properties. They demonstrate the air is matter and observe the effect of molecular motion through these activities.

Students experiment with inner tubes, weights, flasks, and pistons to demonstrate the gas laws. In this molecular motion instructional activity, students demonstrate pressure as a force per area. They conduct an experiment to show the...

In this gases worksheet, students review the 3 states of matter, the types of molecular motion, and the characteristics of gases. This worksheet has 30 problems to solve.

Middle schoolers explain the relationship between molecular motion and the slippery properties of ice.
