The Mighty Mathematics of the Lever is a new TED-Ed lesson about how and why levers work. The illustrations in the video demonstrate the mathematical principles involved in levers being use to move heavy objects. The complete lesson with multiple choice questions can be found here. The video from the lesson is embedded below.
Applications for Education
To continue the lesson on levers have your students try the Simple Machines game from the Museum of Science and Industry, Chicago. Simple Machines is a game that is designed to help students learn about the basic physics principles involved in the use of levels, pulleys, planes, axles, and wheels. The object of the game is to help a robot character named Twitch gather the pieces needed to make a simple machine. In order to gather the pieces students have to help Twitch climb over objects using inclined planes, roll to objects as efficiently as possible, and lift objects by using pulleys and levers.
