The Developing Chick-Egg Set

This summer, I saw a really interesting tool for studying chickens at My Montessori Journey.  It was a chicken hatching set that you can buy for about $35.  It was a great idea, but I decided the kids might get more out of it making their own.  So, earlier this summer at Grams' house, I printed out some chicken embryo pictures.  One set has the developing chicken embryo with the yolk and the other is simply a picture of the embryo by itself on days 5, 6, 10, 12 and 18.  We got some wooden half-eggs from Hobby Lobby and created our own set of developing chicken eggs:
