Learners test two jars containing soil, one covered and one open, for changes in temperature. After placing the jars in the Sun, learners discover that the covered jar cools down more slowly.

In this activity, young learners will explore light and darkness through flashlight play.

In this activity, learners examine fingerprints. Learners leave a hidden print on a surface and then make their own print detecting powder from graphite (found in pencils).

Learners test two jars, one containing plain air and one containing carbon dioxide gas, to see their reactions to temperature changes.

In this activity (2nd on the page), learners conduct a series of tests to find out which foot is more dominant. In other words, are they right-footed or left-footed?

In this activity, learners discover how frogs' bodies change while growing from a tadpole to a frog. Learners create a simple craft that gives a visual display of the metamorphosis process.

In this cooperative game, learners devise strategies about sharing a small space with each other.

This activity demonstrates the specificity of viral vectors for target cells in gene therapy delivery methods using two approaches: 1) STYROFOAM® models demonstrate viral ligand binding to receptor pr

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

In this activity, learners explore how to protect their skin while applying pesticides to plants.

In this activity (on pages 36-39), learners make a model of a watershed out of paper, then run water down the mountain to simulate how rainfall and pollution affect watersheds.

Fat is a very important component in our diet. It's the most efficient source of energy in our bodies, and plays an important role in the flavor of foods.

In this game, learners create flash cards with an image on one side (of an animal, for example) and the sound that animal makes on the other.

In this activity, learners create a simple “top” from a CD, marble and bottle cap, and use it as a spinning platform for a variety of illusion-generating patterns.

In this activity (Page 30 of PDF), learners investigate the evolution of wheat by conducting sedimentation tests on different flours.

In this activity, learners explore the different salinities of various sources of water by taste-testing.

This activity was designed for blind learners, but all types of learners can use it to organize an interactive model for learning the classification system (taxonomy) of living things.

In this astronomy activity (page 3 of the PDF), learners will examine the effects of gravity on a person’s pulse and explore how gravity can differ from planet to planet.

In this activity (1st on the page), learners conduct a series of tests to find out which of their hands is more dominant. In other words, are they right-handed or left-handed?

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.
