Beautiful Earth Day

I am working on celebrating holidays with my class. Since we are 4th graders I explain the historical significance of an upcoming holiday and then we do an activity. This month there is Earth Day.

I found this idea on one of the many pinterest boards that I follow. They are recycled water bottle "chandeliers." The students color the outside of plastic bottles with sharpie and cut a spiral around it. Then, I tied them together and hung them up. I have to say they are quite stunning.
