This stop motion animation replaces one originally created by these students. It was inadvertently erased. Their original artwork and construction was taken apart. They used the photos from a book titled: "Switch On, Switch Off" by Melvin Berger to help explain the concepts behind renewable energy.
Thanks to Beth F, Charles, Andrew, and Ed for the patient and generous technical assistance.
Any technical difficulties are due to this blogger's inexperience with the medium.
