In this chemistry activity (page 1 of PDF SciGirls Activity: Milk Carton Boat), learners will create a blob of stretchable funny putty out of a water, borax, and glue mixture.

In this activity, learners explore how ordinary marshmallows expand when heated in a microwave.

In this activity, learners investigate diffusion by creating underwater "fireworks" using food coloring, oil and water.

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

In this activity, learners follow a recipe to make hollandaise sauce. Learners discover how cooks use egg yolks to blend oil and water together into a smooth mix.

In this activity, learners add food coloring to hot and cold water to see whether heating or cooling affects the speed of water molecules.

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.

Using two baby food jars, food coloring, and an index card, you'll 'marry' the jars to see how hot water and cold water mix.

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 quick activity, learners break the tension that happens when water develops a "skin." Learners use water, pepper and some soap to discover the wonders of surface tension—the force that attract

In this activity (page 12), learners explore how molecules self-assemble and how molecules must fit together, like a lock and key, in order to identify each other and initiate a new function as a comb

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).

In this quick activity, learners drink Avogadro's number worth of molecules - 6.02x10^23 molecules!

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 activity, learners conduct an oxidation experiment that turns old pennies bright and shiny. Learners soak 20 dull, dirty pennies in a bowl of salt and vinegar for five minutes.

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 activity, learners explore how molecules must fit together, like a lock and key, in order to identify each other and initiate a new function as a combined unit.
