I have an idea for a small cooperative group project involving simple machines. I am a ST this semester and I'm doing a unit on simple machines. I don't have all of this planned out yet, but I was thinking of getting the students to pretend that they are stranded on a desert island with three simple machines of their chioce. I will also incorporate social studies as we have been studying continents and oceans. I want them to brainstorm which simple machines they would choose and why and prepare a small poster. Does this sound corny??? It just popped into my head this afternoon. Any feedback would be helpful. Thanks!
