Abstract
A lever system teaching tool includes a frame and an elongate member that is releasably coupled to the frame. The elongate member defines a plurality of mounting stations along its length. The elongate member can be pivotally or rotatably coupled to the fulcrum of the frame at any of the mounting stations. The elongate member includes repositories at opposite ends of the elongate member. The repositories are sized and shaped to retain one or more incremental loads.
Claims20
A teaching tool comprising:
- a frame including a fulcrum;
- and
- an elongate member extending along a length between opposite first and second ends, the elongate member defining a plurality of pre-determined mounting stations disposed along the length, wherein each mounting station is configured to be selectively coupled to the frame so that the elongate member rotates relative to the frame about the fulcrum;
- a first load repository disposed at the first end of the elongate member;
- and
- a second load repository disposed at the second end of the elongate member.
A method of teaching physics concepts to students using lever system including a frame and an elongate member, the elongate extending along a length between opposite first and second ends, the elongate member including a first repository at the first end and a second repository at the second end, the method comprising:
- selecting one of a plurality of mounting stations along an elongate member;
- coupling the elongate member to a frame so that the selected mounting station engages a fulcrum of the frame, wherein the first end of the elongate member extends outwardly from the frame in a first direction and the second end of the elongate member extends outwardly from the frame in an opposite second direction when the elongate member is coupled to the frame;
- and
- applying at least one weight to the first repository.
