Simple machine experiments using seesaws, wheels, pulleys, and more : one hour or less science experiments / Robert Gardner. - [Library ed.]. - Berkeley Heights, NJ : Enslow Publishers, c2013. - 48 p. : col. ill. ; 24 cm. - Last-minute science projects . - Last-minute science projects. .
Includes bibliographical references (p. 46-47) and index.
Are you running late? -- One hour or less -- 30 minutes or less -- 15 minutes or less -- 5 minutes or less.
Describes experiments involving simple machines that follow the scientific method, and can be completed in an hour or less. Explore using levers to control motion and lift, and how the steepness of inclined planes affects the force needed to move something. Most experiments also include ideas for science fair projects.
