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: _dPY-UOI - How the World Works
