A Balance Becomes A Catapult

During lunch last week D.BC mentioned to me that he would really like to do an activity with seesaws and catapults. I discussed this idea with Kara (whom had recently finished teaching them all about balances) and our lesson was formed. We began by reviewing Kara's lesson on balances with the children and letting them use anything in the classroom to make a seesaw. After a quick brainstorming session on what could be used for the base and beam the children were off and creating their seesaws with triangles, blocks, yard sticks and rulers.
