In this activity, learners get a closer look at the shape of a drop of water and a drop of oil. Learners first drip water onto wax paper and examine the shape of separate drops from a side view.

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.

In this activity, learners design a flag for a chosen or assigned planet. The instructions include information about flags on Earth, and a list of flag references.

In this activity, learners investigate the behavior of magnets. Learners create a "wonder wand" with a magnet so they can move a skater around.

In this activity, learners develop an understanding of cylinders and volume as they compare two sizes of popcorn buckets.

In this activity, learners working in pairs saturate a cotton ball using water drops from an eyedropper to demonstrate the high water capacity of clouds.

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.

Learners place multiple M&M's in a plate of water to watch what happens as the candies dissolve.

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.

Learners experiment with a 2-liter plastic bottle containing water and four “divers." The divers consist of open, transparent containers with the opening points downward.

In this activity, learners experiment with shadows and light sources to understand the relationship between the angle illumination and the shadow's length.

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, groups cut out and sort cards showing items recovered from a crash landing on the Moon. The 12 items range from food and water to rope and matches to a self-inflating life raft.
