In Science we have started a unit on simple machines. This day we were talking about friction. First, we used three wooden blocks. One was plain, one I stuck a piece of fun foam on, and one we covered with parchement (since I was out of waxed paper). Then we slid them down this board and talked about how friction makes things go slower. After that K. decided she should slide down the board. Then I gave her a piece of parchment to sit on. She went down so quickly that it was hard to get a good picture of her -- but she understands about friction!
