Day two, we move on to magnetic energy.  Check out Science Bob for today's experiment or click the picture below.  It was a very simple experiment using only a D cell battery, an iron nail and about 4 feet of thin COATED copper wire.  The kids loved it and were able to experiment with different numbers of coils and how that affected the strength of the magnet.  This also led to yet another great discussion about thermal energy, as the parts get nice and toasty!

STILL looking for electricity activities and ideas.  If ya got em, share em!  PLEASE????!!!!????
