We started off with a lab test on wheels and how different wheels work. Then, we looked at pulleys and wheels as simple machines. We learned how to graph circles and ellipses and later moved on to study weight, mass, speed, velocity, and acceleration. We also learned about functions, energy, and gears. The Field Experiences this term were with Earth Rider Cycling, Divvy, and Dyson. At Earth Rider, we talked about electric bikes with the owner of the shop and had the chance to ride electric bikes. A guest came in from the Chicago Department of Transportation with Divvy and talked to the class about how the bike share system can remodel city transportation. Meeting with Dyson helped us learn how to prototype and pitch our ideas. These have all led up to the Action Project of designing a bike of our own. This bike has to meet the need...
