“This DVD includes graphics that are clear and well-sequenced, making them suitable for most elementary and middle school student. The graphics and movie clips will enable students to develop a deeper understanding of concepts…This set would be an asset for differentiated instruction, high school special education classes, and elementary and middle school classroom teachers. It would also be helpful to curriculum coordinators as they assist and mentor new teachers who are not comfortable teaching these science concepts.”
