Create a chemical reaction that makes cheese! This hands-on activity demonstrates that molecules and atoms are tiny particles that make up everything around us.

In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

Learners add drops of four liquids (water, alcohol, salt water, and detergent solution) to different surfaces and observe the liquids' behavior.

In this activity, learners cut out a fish and then "paint" it using universal indicator and acids and bases.

In this chemistry demonstration, learners will discover that phenolphthalein is a chemical that displays different colors depending on the acidity or basicity of the environment.

In this activity (on page 2 of the PDF), the learner places a golf ball between salt water and colored fresh water. The golf ball is not as dense as the saltwater.

In this activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.

Learners design their own experiment to investigate whether the temperature of the surrounding water affects the rate at which the colored coating dissolves from an M&M.

Learners create hard water by mixing Epsom salt and water. Then they compare what happens when soap solution is mixed with hard water and regular water.

Learners apply their knowledge from a previous study to identify different liquids--water, corn syrup, and vegetable oil.

In this activity, learners mix white craft glue and borax solution together to produce a surprising new material: GOOP!

In this activity, learners make a paper model of a polymer, then make Silly Putty, an actual polymer.

In this activity, learners will discover what colors are in different markers, and may be surprised at the results.

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

In this combination chemistry and physics activity, learners explore water absorption in dried beans or peas and learn how this affects their physical properties.

Can you think of ways to collect and dispose of spilled oil without causing further harm to the environment?

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

Eggs are placed in vinegar for one or two days to dissolve the shells. Then, learners place the eggs in water or corn syrup and observe them over a period of days.

In this playful, goopy activity, learners mix two liquids to create a solid (that sometimes acts like a liquid ), using basic household materials such as borax and glue.

In this activity, learners will create beautiful greeting cards by marbling with shaving cream and food dye. They will explore the chemistry behind the art of marbling.
