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.

 Then we did an experiment with a glass jar, and some paper clips to see if we could move them through the jar with the magnet.  We could, even when they were attached to something heavy like a clay snake.  We tried several other mediums to try and pull things through.  The table was too thick.  A lego board worked. As did a plastic cup.

We learned about polarity, and the north-south pull of magnets, and did an experiment by putting the horseshoe magnet on a stick and watching it "magically" rotate so that it was always pointing north/south.

Overall, a very fun way to spend an afternoon.
