Since I’ve been there, we started a new science unit on structures. This is one of the cool videos that I found online, from Bill Nye the Science Guy. I loooooove him. He has a way of explaining things to kids and making it so much fun! Although it’s a bit dated, and the boys thought it was pretty funny, they still learned a lot from it.
This website I found, thanks to Pinterest, has all ONE HUNDRED FULL EPISODES of his show! Sweeeeet!
