In this activity, learners investigate the effect of heat on a reaction.

In this activity on page 4 of the PDF (Water in Our World), learners conduct some quick and easy tests to determine the differences between water and other liquids that look very similar to water.

In this activity about molecular diffusion (located on page 2 of the PDF under Nanosilver Activity), learners will make predictions and move molecules of iodine through a seemingly solid plastic sandw

This fun video explains how to make a batch of oobleck (or slime) and why this special substance is known as a "non-Newtonian" fluid. Watch as Mr.

In this activity, learners construct and launch rockets using simple materials and their understanding of chemical reactions.

Learners discover that soap can be used to power a boat. Learners make a simple, flat boat model, put it in water, and then add a drop of detergent at the back of the boat.

In this activity, learners use gumdrops and toothpicks to model the composition and molecular structure of three greenhouse gases: carbon dioxide (CO2), water vapor (H2O) and methane (CH4).

Learn about dyes and mordants (fixatives) when you tie-dye fabric with Kool-Aid™ and vinegar. The colored molecules in Kool-Aid™ form a chemical bond between the fiber and dye molecules.

In this three-part activity, learners play a game and conduct two simple experiments to explore water and surface tension. Learners will have fun discovering how water "sticks" together.

In this physics activity (page 4 of the PDF), learners will construct their own spiral "snake" and use it to explore the relationship between heat and kinetic energy.
