“Understanding simple machines and their relationship to how things move is the backdrop for this DVD…With the script in hand, teachers can stop the video before each section to set the stage and have students share what they already know about the simple machine that is coming up. After the segment, the video can be stopped so that concepts can be clarified or to list other examples of the simple machine that was just shown. The script also allows teachers to help develop vocabulary with ESL students.”

“The narrator presents the information in a well-paced, easy-to-understand manner…This excellent introduction to a basic science concept will fit nicely into any science curriculum dealing with simple machines.”

-School Library Journal, September 2007
