For Thursday:

It's simple: Design something that will fall fast. We tried a bit of this with two lumps of clay, but we probably need to drop them from a greater height, such as the roof of Olin. We can do this, but first we ought to have some good things to drop.

Let's continue to use a sphere as our standard. We talked about adding fins - I'd like to see you try that, maybe. I've left the modeling clay in the classroom, so you might try shaping some good stuff from it. Can you make a lump that falls more slowly than the sphere? Faster? Can we finally compare torpedoes going down blunt-end-first with those going down pointy-end-first?

Your contribution to this project will constitute part of your score on this Friday's test.

For Friday:

Remember, both of your dropping objects must have the same mass, and we don't want there to be any big differences between that mass and the mass of everyone else's objects. And, we want everything to be made (mostly) of clay. (No, I do NOT want to see any paper parachutes - let's restrict the use of paper to fin construction.)
