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.

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 of all ages will roll a ball coated with paint to artistically visualize the motion of the object.

In this activity, learners of all ages will design a functional bird feeder using familiar, every day materials.

In this activity, learners examine the properties of different seaweeds, investigate what happens when powdered seaweed (alginate) is added to water, and learn about food products made with seaweed.

In this activity, learners design and build a Zoom-a-rang using everyday materials. Experiment with different materials and Zoom-a-rang designs to see how they fly.

This is part 2 of the three-part "Crayon Rock Cycle" activity and must be done after part 1: Sedimentary Rocks. In this activity, learners explore how metamorphic rocks form.

In this activity, learners play a card game that explores the relative sizes of various objects. Learners compete to organize their hand of cards into lists of objects from largest to smallest.

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

In this activity, learners mark their height on a height chart and discover how tall they are in nanometers.

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

Using a vertical wind tube and using simple materials, individuals and groups attempt to design a "satellite" that floats for at least 5 seconds.

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

In this fun and, at times, hilarious force and motion activity, learners will use household objects to build a crazy contraption and see how far they can get a tennis ball to move.

In this activity, learners will explore how maps can provide information about a place and help us find our way from one location to another.

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 will discover how to make butter from scratch. One optional tips includes adding marbles to speed up the process.

In this activity, learners explore how the application of nano-sized "whiskers" can protect clothing from stains.
