In this art meets science activity, learners pack silver, ball-shaped ornaments in a single layer in a box to create an array of spherical reflectors.

In this chemistry challenge, learners identify which plants have the enzyme "catalase" that breaks hydrogen peroxide into water and oxygen.

In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

In this activity, learners will turn cream and salt into butter—using marbles. Learners will explore how shaking up fat globules help them create homemade butter.

In this activity, learners will experiment with water- and air-filled balloons as a way of dampening sound before it reaches their ears.

This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.

Can you think of ways to collect and dispose of spilled oil without causing further harm to the environment?

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

In this optics activity, demonstrate diffraction using a candle or a small bright flashlight bulb and a slide made with two pencils.

In this activity, learners perform 20 arm curls with cans that simulate the weight of beans on Earth versus the weights of the same number of beans on the Moon and in space.

In this experiment, learners work in pairs to create two gloves -- one that contains a layer of shortening (blubber) inside, and one that doesn't.

In this activity, learners examine how colored lenses act like filters and absorb all colors of light except for the color of the lenses.

In this optics/mathematics activity, learners use two hinged mirrors to create a kaleidoscope that shows multiple images of an object.

In this activity, learners make their own heat waves in an aquarium.

Cool off in the heat with this project! Learners use simple materials to build a fan that runs on a motor.

In this activity, learners will make fish cutouts that propel through the water with the help of surface tension.

In this activity, learners create a sound visualizer from common materials to help see the vibrations created by sound. Sounds from a tone generator make salt dance on a vibrating balloon membrane.

This is an activity exploring color and color mixing.

In this activity, learners burn a peanut, which produces a flame that can be used to boil away water and count the calories contained in the peanut.
