Simple Machines

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 distance
some jobs take more work that other jobs
machines make work easier
machines may have few, many, or no moving parts
the lever is a simple machine
the wheel and axle is a simple machine
the pulley is a simple machine
the inclined plane is a simple machine
the screw is a simple machine
the wedge is a simple machine

Activities 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 effect

Samples of the hands-on learning experiences:
hold a machine celebration where guests try simple machine challenges
analyze the simple machines that make up common household machines
make a model seesaw to discover how this lever works
conduct a "broomstick tug-of-war" to discover how a pulley helps do work

Contains 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.
