PRODUCT SUMMARY
For sale in U.S. and Canada only-- In Floating, inhabitants of Mammoth Island attempt to rescue an islander and his mammoths from the middle of a lake. They are stranded on a small island after a wooden bridge collapses. Olive, a bright young islander, notices that the wood from the broken bridge is floating on the surface of the lake. With the help of a visiting inventor, she discovers the principle of buoyancy. Every object exerts a downward force on the water and the water pushes back with an upward force on the object. When the buoyant force is greater than an object’s weight, the object floats! 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)
