In this chemistry activity, learners use guar gum to make slime. Use this activity to introduce learners to polymers, viscosity, and colloids.

The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.

Learners observe a sealed test tube containing a small amount of solid stearic acid.

In this demonstration, learners can observe a number of small convection cells generated from a mixture of aluminum powder and silicon oil on a hot plate.

In this activity, learners test what happens when they put baking power on different frozen liquids.

In this activity, learners use gelatin as a lens to investigate the properties of laser light.

Learners mix liquid water with solid cornstarch. They investigate the slime produced, which has properties of both a solid and a liquid.

In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.
