Students were grouped into four groups of four. Each group was armed with a secretary, board, timer, tape measure, ball, string and a recording sheet.“Instead of just using formulas in class, this experiment gets them out of the classroom and gives them a better understanding of calculating acceleration,” Wallace said.
While one student dropped the ball, another timed how long it took to hit the board. Students repeated this step six times to get an average time. Then students measured the length of the drop with their string.
