This book contains graphs showing data from analyses of tools, including a hammer, wrench, pliers, screwdriver, and two styles of hand-crank drills. Additional graphs contain tests of miniature bricks, cement, and soil, plus tests of wall stability and heat transfer through brick and wood walls. The data are collected on miniature items, providing sample data to elucidate concepts associated with construction. These data can be used for lesson plans by teachers and parents. Bonus Material: Data on heating equipment and electric tool power usage are provided via reprints of graphs from "Heat, Energy, & Light Bulbs! The Science of Energy Efficiency" Volumes 1 and 2, by M. Schottenbauer, Ph.D. Appendices contain pictures of tools and diagrams of experimental setups.
