In this fun gardening activity, learners discover their soil type. There are three basic soil types: sand, silt, and clay.

In this activity, learners make "totally tubular" forms of carbon. Learners use chicken wire to build macro models of carbon nanotubes.

In this activity about electricity, learners explore how static electricity can make electric "fleas" jump up and down. Learners use a piece of wool cloth or fur to charge a sheet of acrylic plastic.

In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.

Learners explore three-dimensional geometric frames including cubes and tetrahedrons, as they create bubble wands with pipe cleaners and drinking straws.

This is an activity that models the operation of a seismograph, a tool used to measure the size of earthquakes.

This is an activity about a very important ingredient in most baked goods - gluten! Why is gluten so important? Without it, there would be nothing to hold the gas that makes bread rise.

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 activity, learners hook up a hair to a lever system and create a hair hygrometer to measure changes in humidity.

In this collection of demonstrations, learners explore Newton's Laws of Motion.

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, learners discover the primary physical properties used to separate pure substances from mixtures.

In this activity, learners explore what happens when polarized white light passes through a sugar solution.

In this activity, a lightbulb is placed in front of a concave mirror. The actual lightbulb is not visible to the viewer, but the viewer can see the mirror image of the lightbulb formed in space.

If a sailboat is stranded because there is no wind, is it possible to set up a fan on deck and blow wind into the sail to make the boat move?

Did you know that you would be a different age if you lived on Mars? It's true!

In this activity, learners build inexpensive pulley assemblies from pulley wheels used for sliding screen door replacement or from clothesline spreaders.

In this physics activity, learners conduct two experiments to explore free-falling.

In this activity, learners explore center of gravity, or balance point, of stacked blocks.

In this activity, a spinning bicycle wheel resists efforts to tilt it and point the axle in a new direction.
