Transfer of Energy

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 ramps,  marbles, blocks, and assorted parts to construct a chain reaction that could include your whole class—thoughtful lessons in mechanics, invention, and teamwork. 

This project spans the ages and is a popular program for Adult Professional Development groups. We can use it as a hands-on means to teach a variety of concepts.

The power of machines guides and eases work. The screws, threads, levers and pulleys of this machine organize effort into power you can feel. Students assemble interchangeable parts and invent a personality for their machine while experimenting with all Simple Machines and testing them first hand.

Construct a music machine. Hear the logic of Leonardo's mind at work as he invents the first modern robot, an automatic drummer whose rhythms can be reprogrammed flexibly and whose tempos adjust automatically. Invent your own cadences and rhythms.

The legacy of the Museum begins in 1798 When Eli Whitney first chose a site on the Mill River to build his Armory. Chosen for its access to a strong current of water, Whitney intended to use this as a power source for the machines he would use to produce the parts of his contract musket. Whitney, however, was not the first to see the potential of this site as a grist mill had been located on the grounds previously. Over time the site has taken on new residencies and has physically changed as well.

Along with learning the history of Connecticut’s part in the Industrial Revolution, discover and build the inner workings of a Mill model. Explore the connections and how this machinery helped energize generations to come. 
 

Build a windmill with adjustable vanes. You will discover that in order to make it work, the vanes have to be adjusted just right to turn fast enough to work. Then apply that wind power to make it work. How? By making it lift weight, you can observe just how much power output it can produce. You will discover the problem of scale and its limitations but the potential is there.

Understand the gearing needed to manage the lift. About the relationship between speed and power. It's not necessarily intuitive.

The English Scientist, Neil Downie, has written three volumes of Saturday Science Projects. His designs are remarkably original and thoughtful., explaining the math and science of every project.
Looking at waveforms 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. Note whether the speed of the wave is the same on the inside and outside. What is the shape of the wave? So much to learn. Thoroughly enjoyable to do.
