We are doing a unit on the skeleton. I am LOVING it! We made play-do bodies with and without tooth picks to emphasize the importance of bones for our bodies ability to be able to stand upright. Simple, yet fun. It was a great way to include the youngest in a more difficult lesson. The older two, of course, had to give a bit more verbal detail and such, but everyone got to participate.
Please note: I do have boys, so of course the bodies had to be super heroes of some sort, complete with swords in hand. Gotta love those boys.
We are also making a paper skeleton to add organs and muscles to as we continue our body study. Awesome!
