In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.

In this optics activity, learners discover basic lens-making techniques by using a tennis ball to make a lens out of ice.

In this activity, learners make some music by constructing a kazoo out of a simple plastic drinking straw. Use this activity to explore sound, vibrations, and music.

In this activity, learners explore how salt water freezes in comparison to fresh water.

In this activity about light and refraction, learners make a lens and magnifying glass by filling a bowl with water.

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.

Align four color transparencies, each one a single color (cyan, magenta, yellow, and black), and see a beautiful full color image.

In this activity, learners create a xylophone by filling glasses with different amounts of water and tapping them with a metal spoon.

In this activity, learners explore why the sky is blue. Learners model the scattering of light by the atmosphere, which creates the blue sky and red sunset, using a flashlight and clear glue sticks.

In this optics activity, learners create a ripple tank from household materials to study waves. Learners build the tank and then explore by making various types of waves.

In this optics activity, learners experiment with polarizers (small dark rectangles) to examine light intensity.

In this activity, learners discover if carbon dioxide has an effect on temperature.

In this fun activity about spiders, learners build and design a spider from cardstock, straw, string, and pipe cleaners.

Create an illusion where it appears that your hand has a hole in it. You'll see the results from when one eye gets conflicting information.

In this group activity, learners see and hear the speed of sound. A learner designated the "gonger" hits a gong, once every second, as the rest of the group watches and listens from a distance.

In this activity, learners explore the behavior of cold-blooded animals. Learners discover what happens when they change a fly's temperature.

In this activity, learners (at least three) work together to explore the effects of atmospheric pressure.

In this optics activity, learners explore color by examining color dots through colored water and the light of a flashlight.

In this optics activity, learners explore how light bends and affects what we see.

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