In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

In this physics activity, learners will explore buoyancy.

In this activity, learners create a map of a hidden surface using a "sounding stick" -- a technique similar to how underwater maps were once made.

In this activity learners will build roller coasters and test them using small balls or marbles.

This is a guide for facilitating interaction at a touch tank with marine animals. The instructions are for setting up a display in an informal science center, but could work anywhere.

In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.

In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.

In this activity, learners observe hard parts of sea creatures (shells, molts, etc.) to better understand marine environments.

How many colors make black? Gather as many water soluble black markers as you can find.

In this activity, learners touch and observe skulls of sharks and rays to learn about their diversity (over 400 species of sharks alone!).

Are fingers the only place on the body where we use our sense of touch? In this activity (6th activity on the page), learners test the touch sensitivity of different parts of the body.

In this easy demonstration (3rd on the page), learners explore depth perception by conducting a test with two pencils.

In this activity, learners construct a home-made journal with simple, everyday materials.

In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.

This activity offers learners and their families several ways to raise their awareness together about home water.

This fun hands-on astronomy activity uses a variety of simple props to help learners understand why they see what they see in a telescope.

In this activity (17th on the page), learners investigate why you cannot see colors in dim light.

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

In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.

In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.
