Most of our students know that we celebrate Earth Day "sometime in the spring", but do your students know the origin and history of Earth Day?
The first Earth Day was organized by Wisconsin senator Gaylord Nelson, and was held in 1970. Since that first observance of Earth Day, it has turned into a global event that is recognized by millions around the globe. I prepared a 25-slide PowerPoint for my biology students to teach them about the history, background, and origin of Earth Day. This is a FREE download and all are welcome to use it in your classrooms. It is suitable for children of all ages.
Enjoy this freebie......
.....and Happy Earth Day!!
