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 will explore the insect life cycle by making a model.

Learners experiment with a commercially available liquid-crystal coaster. They warm the material with their hands for varying lengths of time and observe the changing colors that result.

In this math game, learners solve a mind-twisting puzzle using dominoes. Use this activity to help learners practice counting, adding, and solving problems.

Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.

In this activity, learners will experiment with the physics of forces - kinetic energy and friction while making a moving toy woodpecker.

In this activity, learners will experiment with the physics of flight by making a gliding contraption with strange looking wings. The activity explores flight with connections to the natural world.

In this math activity, learners pretend there is a special store that lets you pay for toys by their height in pennies.

In this math activity, learners pretend there is a special store that lets you pay for toys by their weight in pennies.

Create your own spinning top, and explore color, shapes and spinning. This activity contains instructions for making your spinning top, and tips on how to design and decorate it.

In this activity, learners try to put together toy bricks—wearing oven mitts on their hands! This activity shows learners how difficult it is to build small things when your tools are too big.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

In this chemistry activity, learners make a slimy non-Newtonian fluid called "Gluep." Use this activity to introduce learners to polymers and viscosity.

In this activity, learners build a LEGO® structure while wearing mittens. This activity shows learners how difficult it is to build small things when your tools are too big.

In this activity, learners concoct some stretchy green goo called Gak. This activity will introduce learners to polymers, chemical reactions, and how scientists invent new materials.

With little more than a flashlight, a straw, and a plastic lid, make an observatory so you can see the amazing colors in bubbles.

Build a car that runs on air. Using household materials, experiment with the power of air to create thrust powerful enough to move a homemade car.
