PRODUCT SUMMARY
For sale in U.S. and Canada only-- In Sensors, Olive and her cousin, Troy, help their family remodel a quaint old lodge in the mountains. They decide that the old building could use some modernization. A visiting inventor suggests some sensors that would help. Sensors are devices that respond to heat, light, sound, pressure, magnetism or motion. The inventor explains the principles behind different types of sensors that can detect the presence of something, such as smoke detectors, automatic doors and security alarms. Part of the multivolume The Way Things Work DVD Series, based on the best-selling book by David Macaulay. A teacher's guide is included and available online.
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)
