The Torque Concept Builder focuses attention upon the variables that affect the amount of torque, the direction of rotation caused by a torque, the +/- sign of torque, and the meaning of lever arm. The Concept Builder consists of 48 total questions organized into 13 different Question Groups and spread across three Activities. In the first activity, Ranking Tasks, learners use information magnitude, direction, and placement of a force along a wrench in order to rank three situations from least to greatest torque. In the second activity, Torque and Rotation, learners use given information about the direction of a force applied to a seesaw to determine the direction of rotation of the seesaw and the sign on the resulting torque. In the third activity, Lever Arm, learners are given a top-view diagram of a door with the hinge, door knob, and a force vector (with varying directions) and they must identify the length of the lever arm (a.k.a., moment arm) on the diagram. Question-specific help is provided for each of the 13 situations. Use of this Concept Builder with our Task Tracker system allows teachers to track student progress.
