Here is what I did, I notcied when our 5 year old was on the pot he would study eitehr a six flags brochure map or a camping camp site brouchure map, so I got a poster of the US and posted it on the wall in teh bathroom. After about a week he had memorized every state and captail city, so I put up a world map. After he had memorized the couintries I asked him about the oceans and seas, and then gulfs, straights and he learned all of them. Since he was into leggos and I math I though he might be interetsed in fining out about chemistry, same thing! I put a periodic table up in teh batchroom and he he memorized every element, series, atomic number and I had to get a Chemistry grad student from the nearest university to answer his questions because they were over my head. Hope this helps
