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

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 trace, cut out and fly a boomerang, outdoors or in a large indoor space.

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).

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

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

In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.

In this activity, learners create a colorful bookmark using a super thin layer of nail polish on water. Learners discover that a thin film creates iridescent, rainbow colors.

In this water activity, learners discover ways to move water across the water table.

Learners cut and fold a paper helicopter from the template in this PDF. They practice twirling the helicopter and observe what happens as they modify their tries.

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

The goal of this activity is to design, build and test a house or toy for an animal.

In this indoor or outdoor water activity, learners pour water from small cups to large cups and containers. In doing so, they discover water takes the shape of its container.

This is an activity about waves. Using marbles, paper clips and rubber bands, learners explore how waves behave.

This warm weather activity introduces learners to the impact trees have on blocking the sun's heat and reducing temperature on the Earth's surface.

The beautiful iridescent colors of a bubble in a can! With this Exploratorium Science Snack, create beautiful soap films on the open end of a can to see beautiful rainbows of color.

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

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.
