Keep Students’ Interest in the Water Cycle from Evaporating

Help your students visualize the formation of a cloud in your hand.

This simple apparatus demonstrates radiant heat.

Examine the Science Behind the Landmark 2005 Hurricane

Simulate the cyclonic motion of a twister.

Demonstrate How to Measure Wind Speed

Students will be able to actually see a normally invisible convection current in action and understand how hot and cold air make the current flow.

Bring the Earth sciences to life and satisfy National Science Standards (NSS) with one of these versatile density flow models. Teacher developed, these educational demonstration models are the most complete and useful tools for simulating the realistic flow of fluids in nature (i.e., weather systems, ocean circulation, mountain building, and plate tectonics).
