Clear Slime Polymer
Source Institutions
In this chemistry activity, learners use guar gum to make slime. Use this activity to introduce learners to polymers, viscosity, and colloids.
Rocket Reactions
Source Institutions
The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.
Phase Changes
Source Institutions
Learners observe a sealed test tube containing a small amount of solid stearic acid.
What is a “Convection Cell”?
Source Institutions
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.
Laser Jello
Source Institutions
In this activity, learners use gelatin as a lens to investigate the properties of laser light.
Starch Slime
Source Institutions
Learners mix liquid water with solid cornstarch. They investigate the slime produced, which has properties of both a solid and a liquid.
Air Pressure
Source Institutions
In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.
