We aren't doing a full-scale Please Touch Museum exhibit for the water wheel. Instead, we are doing a full-scale prototype model of the system of belts and pulleys that would be attached to the water wheel at the museum.
So it's week 6 and the deadline to have a physical representation of what we've been up to is a whole lot closer this side of week 5. We walked all the way down to Wolf Cycle to get bike parts. We got a 24 inch wheel -- that's actually a 19 inch rim when not counting the tire (see picture below) and a fork to fit it.
This bike wheel part (minus the tire) will be the giant wheel from that diagram Jacque drew in week 5's recap. Next we have to calculate out the proportions so all the other wheels will be proportional to our big 19 inch bike wheel.
We also need to order the belts and wait for the motors to get here.
