Delta Science Modules Simple Machines Complete Kit

Grades 5 - 6


Students explore Simple Machines with twelve hands-on activities and the Delta Science Reader. By measuring force as they lift, push, and pull loads, your class will determine the mathematical relationship between force and work. Students build and/or operate classroom versions of the six simple machines: lever, wheel and axle, pulley, inclined plane, wedge, and screw. They investigate how (and how much) each one makes work easier by magnifying, modifying, transferring, or changing the direction of the applied force. By calculating such factors as gear ratios and the negative effects of friction, students discover the tradeoff between force and distance. Students also identify and examine household or other everyday simple machines.

In the Delta Science Reader Simple Machines, students explore the world of simple machines and the energy that makes them work. Students read about the six simple machines?the inclined plane, the lever, the wheel and axle, the pulley, the wedge, and the screw?and understand the difference between simple and compound machines. In biographical sketches, students meet ancient Greek mathematician Archimedes and modern inventor Lillian Gilbreth, and discover how they put simple machines to work. Students also read about the scientific formula for calculating work, the many levers in the human body, and how a roller coaster works.
