PRODUCT SUMMARY
For sale in U.S. and Canada only-- In Screws, inhabitants of Mammoth Island are in the process of building a new observation tower out of stone blocks when one of the islanders gets trapped at the top of the tower. With the help of a visiting gallant knight and his trusty mammoth, they are able to build a ramp around the circular structure and create a giant simple machine known as a screw. Turning the tower into a giant screw allows the islanders to spin the tower down into the soil, bringing the trapped inhabitant of Mammoth Island close to the ground -- and saving the day! 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)
