A couple of weeks ago, we discovered that Lowe's has these awesome horseshoe magnets for $1.70 a piece. Today we bought three more of them (one for each kid, because I was attempting to minimize fights). We decided to learn some things about magnetism. So I pulled out one of our science experiment books, and a piece of poster board, and we got to it. We decided to record our findings on the poster, then as we learn more, we can add on.
First, we told each other what we already knew about magnets, and I wrote that down. Then I sent the kids on a scavenger hunt to find household items, and we tested them with our magnets, which taught us even more about magnetism and what magnets do and do not attract.
Overall, a very fun way to spend an afternoon.
