Explore the streamlined shapes of submarines and design an effective hull shape. Observe how streamlining affects a vehicle as it is pulled through a water-filled trough.

In this activity, students learn about the trade-off between speed and torque when designing gear ratios. The activity setup includes a LEGO pulley system with two independent gear sets and motors that spin two pulleys. Each pulley has...

Through observation and inquiry, students are given various objects to investigate how levers work and why they might be useful.

Young scholars investigate the relationship between the two forces and the location of the fulcrum in a first class lever. Students work in cooperative groups of approximately three to make observations that they can then generate a...

Explore the characteristics of inclined planes while observing how drops of colored water flow down a ramp and on different surfaces.
