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.
Looking at wave forms at different speeds and the effect of weight, air friction and gravity. As the speed changes, see the different number of waves traveling around the edge of the cloth.
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.
Build a vibrating motor block that will drive the Vibrocraft scampering around the room. Experiment with different kinds of 'feet' to discover just which work best for the desired results. An introduction to the art of experiment. Begin to understand friction and get some control.
Experiment with mechanical movement: use cams and wheels to change the speed, direction and shape of motion. Invent applications for motions: create figures that dance or jump, fence or box. Put your imagination in motion.
Wheels, axles, chassis parts, connectors and rubber bands 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.
