Product Details

Challenge students to locate the center of gravity for objects of various shapes. Students place the corner of one polygon on a hook so that the object hangs freely. Then, they hang a weight tied to string from the same corner. Using a dry-erase marker, students trace a line on the polygon that is defined by the hanging string. Students repeat the process from two different corners of the polygon. The three traced lines will all intersect at the same point-the center of gravity! Students locate the center of gravity for five different polygons. Includes two sets of five polygons, string, weights, S-hooks, dry-erase markers, detailed instructions and Teacher's Notes. Super Value Kit is complete for 10 student groups. All materials are reusable! Support stands and clamps are required and available separately.
