We've had such a wonderful time learning about our environment in preparation for Earth Day. I was able to use two wonderful resources to help me teach. If you have not done so, go purchase Earth Day Activities and Crafts by A Year of Many Firsts and Fran Kramer's Friends of the Earth unit. You will not be disappointed.
As a culmination of our learning, we created these Earth Day mobiles using washable markers and a coffee filter. After our Earths dried, I used contact paper to preserve them for their memory box later.
