In this activity, learners will build a stomp-powered launcher to blast off paper rockets they design. Materials can be found at a local hardware store or you may already have them at home.

This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).

Water treatment on a large scale enables the supply of clean drinking water to communities.

In this activity, learners are challenged to design and construct a trophy for prize-winning sports equipment.

In this activity, learners investigate vitamin C.

In this lab, learners evaluate the relative effectiveness of various chemical substances (i.e. garlic powder, bathroom cleaner, mouthwash, etc.) as antimicrobial agents.

In this outdoor activity, learners work in pairs using their senses—especially touch—to learn more about individual trees.

In this optics activity, learners discover that not all shadows are black. Learners explore human color perception by using colored lights to make additive color mixtures.

This display shows slow chemical reactions in colorful crystal formations known as Liesegang Rings. These reactions are similar to those forming the rings in agates.

In this activity, learners use bubbles to investigate the structure and unique properties of cell membranes. Bubbles serve as macroscopic models that mimic the cells' phospholipid bilayers.

In this activity, learners use simple tools to build a bookshelf with a built-in bookend.

Learners observe and compare the sizes of three toy “growing” crocodiles made from water-absorbent polymers. One is it its original state, dry, hard, and about 10cm long.

In this activity, learners will use chemistry to create a night sky watercolor painting. They will experiment to learn the effects of mixing crayon, salt, and lemon juice with water color paints.

Water sticks to all kinds of things in nature — flowers, leaves, spider webs - and doesn't stick to others, such as a duck's back.

In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup.

In this activity, learners design and build their own parachute using household materials with the goal of landing their passenger safely on a target.

In this chemistry activity, learners use chemical reactions to observe the composition of an alloy.

In this chemistry activity, learners make indicator solution from red cabbage. Then, learners test everyday foods and household substances using the cabbage juice indicator.

In this activity, learners experiment with hydrogen peroxide, vinegar, yeast, and baking soda to produce hot and cold reactions. Use this activity to demonstrate exothermic and endothermic reactions.

Make a one-string "guitar" by stringing a cup with some fishing line. You amplify the plucking of the string by placing a piezo contact microphone and mini battery powered amplifier inside the cup.
