Week Five

Week Five: Materials McGuyver

This past week, we continued testing our demonstrators and started constructing finished products. The model for the atomic structure of a metal undergoing thermal expansion will be finished this week; more springs of varying tensions will have to be acquired, but the overall effect with be worthwhile when explaining how atoms increase and decrease in size when subjected to different temperatures.

We are still trying to ground and modify the brass ball and hoop model; the resistance heating coil has been ordered and will be tested this week during lab in the Makers Space. The pipette for the water bottle demonstrator will also be ready for lab this week and tested on Tuesday. Our biggest topic of interest this week is to figure out how to mount the brass ball and hoop model onto a grounded structure that both holds up the brass ball and conducts the added heat so the apparatus is safe to use. We will also have to modify the diameter of the coil to fit the brass ball.
