This translucent model provides a detailed, three-dimensional view of cell.

Unique Manipulative For Visualizing How Bullets Are Traced to a Particular Firearm

Estimate stream quality as it relates to solids in the water.

Create Dramatic Electrostatic Effects

Demonstrate that a charge cannot exist inside a conductor and re-create Faraday’s classic 'Ice pail' experiment with this kit.

Ideal for measuring turbidity in streams where a Secchi disk can't be used.

Visualize seasonal changes with this six-globe seasonal display model.

Water sampler for samples of lake, river, or stream water.

For consistent readings underwater.

This device shows how the sun's appearance changes over a period of one month.

This generator can perform all electrostatic experiments on a spectacular scale.

Explore Direct Current Circuits

The Sunspotter Keplerian Telescope lets users safely view the light of the sun.

Simulate a flowing stream and study erosion with this classroom stream table.

Graphically illustrate the fact that like charges repel each other.
The multi-colored ribbons are connected to a suction cup that sits on top of a Van de Graaff generator. As the generator operates, the ribbons accumulate a charge and stand on end.
