In this exciting investigation...
Students fly rubber band-powered toys along a line to think critically about motion. They use reference points to establish the trolley's initial and final positions in order to determine the distance the trolley moved. Change of position is introduced as the definition of motion, and the conventional symbols for positioin, change, and distance are introduced.
Students participate in the design of an experiment to determine the relationship between the number of winds on the rubber band and the distance traveled by an air trolley. After acquiring data for different numbers of winds, students graph the results to look for a relationship. The conventional form and procedures for preparing two-coordinate graphs are introduced.
Students analyze graphic representations of races between several competitors in both print and multimedia formats. They determine distance traveled by many different vehicles and exercise their skills related to reference points, symbolic notation, and using the algorithm for calculating distance.
