Create 3D glasses and use them to explore color, light and optics. Fool your brain into 'seeing' three dimensions on a flat surface!

Learners add drops of four liquids (water, alcohol, salt water, and detergent solution) to different surfaces and observe the liquids' behavior.

This is an activity about our sense of smell and how it compares to sharks' super noses. Learners will create varying solutions of water and perfume.

In this activity, learners use squares to figure out how many border tiles are needed to enclose different areas.

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

This is an activity about lung capacity. Learners will measure their own lung capacity using a homemade spirometer.

Space telescopes can offer us better, clearer views of the universe (and of our own planet) than Earth-based telescopes can, but getting these large, delicate pieces of equipment into orbit is tricky.

In this activity, learners mix white craft glue and borax solution together to produce a surprising new material: GOOP!

In this physics activity, learners explore how sound is created by vibrations.

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 (located on page 6 of the PDF), learners explore the ways people access water in their homes.

In this activity (on pages 4-5), learners make fake snow by adding water to the super-absorbant chemical from diapers, sodium polyacrylate.

In this activity, caregivers and young learners work together to make a scale from household materials to compare different weights--an essential principle in early math.

In this activity, learners build a simple tabletop seesaw to test how different variables (the position of the fulcrum, distance, weight) affect its balance under increasing weight loads.

In this activity, the learner will explore hand eye coordination while using a variation of the ball and cup game.

Learners mix a variety of substances with red cabbage juice. The juice changes color to indicate whether each substance is an acid or a base.

Learners make bell bracelets, place them on their wrists or ankles, and then dance to the rhythms and sounds the bells make. Many cultures use ankle or wrist bells to make music during dancing.

In this activity, learners heat and cool carbonated water to find out whether temperature has an effect on how fast the dissolved gas leaves carbonated water.

In this activity, learners imitate the way vocal cords work by building a model from a plastic cup, rubber band, and a straw.

Learners use their knowledge of color changes with red cabbage indicator to neutralize an acidic solution with a base and then neutralize a basic solution with an acid.
