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 activity, young learners will explore light and darkness through flashlight play.

This is a simple and fun activity for learners to explore water and colors.

In this activity, learners of all ages can enjoy experimenting with ice. Try this experiment at the kitchen table or in the great outdoors to encourage budding scientists to experiment with ice.

In this activity, learners will investigate air and gravity through the use of various fabrics by through them in the air. Activity includes step-by-step instructions and extension ideas.

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

In this activity about ramps, learners explore and measure the rate at which spherical objects roll down a ramp.

In this activity (7th activity on the page), learners use their sense of hearing to find a "sound match." Learners shake containers filled with items like dry seeds, sand, beans, etc.

In this activity, learners investigate how different materials repel or absorb water. Learners use spray bottles to explore how everyday items like sponges, cardboard, feathers, etc.

In this activity, kids make and play with Ooze before testing the material in an egg drop!

In this activity, learners discover how bats use echolocation to get information about objects in their environment. During the activity, one learner whispers into a tube.

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.

In this experiment, learners separate different types of molecules in marker inks (using a technique called "thin layer chromatography").

This open-ended art project allows learners to create their own colorful ice sculpture by using rock salt and food coloring on a solid block of ice.

Learners observe and record what happens when they manipulate bottles containing a liquid (water or corn syrup) and one or more objects (screw, nail, paper clip).

In this up-cycling activity, learners recycle plastic bags and repurpose them into useful wallets.

In this engineering design challenge, learners animate a facial expression and make a machine (zoetrope) that plays the animation back.

Make a rattle-like musical instrument! Shake it, hit it, spin it any way you want to!

In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.

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