For hands-on activities about force, work, wheels, pulleys, and inclined planes that connect science with real life, choose Simple Machines. This book, designed with good science and easy teaching in mind, covers these concepts:work is done when a force is used to move something over a distancesome jobs take more work that other jobsmachines make work easiermachines may have few, many, or no moving partsthe lever is a simple machinethe wheel and axle is a simple machinethe pulley is a simple machinethe inclined plane is a simple machinethe screw is a simple machinethe wedge is a simple machineActivities help children practice skills in: observation, analysis, communication, making comparisons, prediction, critical thinking, and recording. Areas of study address major themes such as: change, structure, function, cycles, diversity, and cause and effectSamples of the hands-on learning experiences:hold a machine celebration where guests try simple machine challengesanalyze the simple machines that make up common household machinesmake a model seesaw to discover how this lever worksconduct a "broomstick tug-of-war" to discover how a pulley helps do workContains many reproducible, ready-to-go resources, such as record sheets, logbook forms, minibooks, and picture cards. Illustrated throughout with fun, yet accurate line art. All 80 pages perforated for easy removal.
