Flying Pulleys

Sometimes you have to strip away all the non-essential parts to see an idea at work. Neil Downie proposes a clever study of the exchange of speed for force. A second array of pulleys float between input pulleys and the output pulley. An elegant display of force in motion.

Mechanical Arm

Based on a design by British scientist Neil Downie, this is an exemplary model. It demonstrates the complex force of flexing muscle. Construct an arm that contracts and extends. consider Leonardo daVinci's study of anatomy and the robot mechanics it inspired. Domo arigato, Robot Armo!

The Whitney Relay

The Whitney Relay is a set of interconnectable parts that lets students master the art and science of energy transfer in the tradition of the Rube Goldberg Machine or its contemporary Japanese masterpiece: the Pythagoras Switch. Each student receives 5 ramps, 8 marbles, 6 blocks, and assorted parts to construct a chain reaction that could include your whole class. Thoughtful lessons in mechanics, invention and teamwork.

Hill Quest

Wheels, axles, chassis parts, connectors, rubber bands and mouse traps are the basic components of each kit that allows students to construct cars that sprint or creep to the top of a wooden ramp…jousting with another student’s car. Challenge: Beat your opponent to the top of the three foot ramp and hold your ground. The project tests all the dynamics of Force and Motion and tests planning and problem solving.
