The Exploratorium

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

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

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

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

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.

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

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

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.

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.

You may have tried to throw a curveball or a slider, or even a screwball, with an ordinary baseball and found it difficult to do.
