PRODUCT SUMMARY
For sale in U.S. and Canada only-- In Levers, inhabitants of Mammoth Island have decided to enter their mammoth in a "heaviest mammoth" competition. To do so, they need to find the best method to weigh a mammoth. After observing some children playing on a see-saw, Olive, a young islander, is inspired to try a simple machine called a lever to get the job done. The Islanders then explore the properties of the three classes of levers and discover that scissors, nail clippers and tweezers are just a few examples of useful inventions based on the principle of the lever! Part of the multivolume series The Way Things Work, based on the best-selling book by David Macaulay. Includes a Teacher's Guide.
EDITORIAL REVIEWS
"The series is humorous, informative and very educational. Explanations are clear and relevant, with neccesary diagrams to explain exactly how things work...These are exceptional physics videos that merit a place in all educational collections."- School Library Journal (August 2003)
"...exceptional...engaging and well-produced...The science is accurate and appropriate for third- through sixth-grade students...a tool teachers can use."- NSTA Recommends (7/18/05)
