Learning to think in graphs can be fun In this book, readers learn about construction in an entirely new way, through graphs This book contains 28 graphs of activities from construction, including: Material Properties, Tool Tests, Lighting & Heating, Energy Efficiency of Appliances, & Alternative Energy Sources. Graphs contain a selection of physics data, including classical mechanics (force, rotational motion), electromagnetism (current, voltage, power, magnetic fields), and optics (light intensity).
