I found these teeth erasers on ebay. You can use them for sorting. Sort by color or sort by degree of cavity! You can also just use them to practice one-to-one correspondence, or to show the kids what happens when you don't brush your teeth very well. The teeth with no cavities have smiley faces, the teeth with little cavities have sad faces, and the teach with big cavities have "ouch" faces. So cute :-)
I wish I had more pictures to show what exactly we did here. But I was busy helping the kiddos stay relatively clean. What we did was put chip crumbs into a plastic sandwich bag, which was the stomach. Bread or Ritz Crackers works better but we don't keep gluten in the house. Then we added stomach acid (for us it was strawberry lemonade), and we crushed and ground all of the pieces, just as the stomach does. This takes some time. Then I got an old stretchy sock and cut a hole in one end (this was the small intestine). I cut a small hole in the corner of the bag and we squeezed the mashed up food into the sock and squeezed it all the way through. When the food made its way to the end of the sock we squeezed it through another sock (large intestine). My three year old understood what we were doing. I don't think my two year old did, but she still had fun!
Just a couple of foam puzzles I also found on ebay. These puzzles are very difficult (especially the skeleton). But after showing my three year old how to do it a few times he can almost put it together by himself. If you'd like to buy these puzzles you could search for them individually on ebay by typing in something like "foam skeleton puzzle."
I simply drew some organs in a sketch pad, cut them out, and the kiddos colored them and glued them to the paper bag.
I love that when my kids draw pictures of a person, they now include their insides!
And for a field trip idea, find out if your science museum or children's museum has a neat human body exhibit like this one!
