Energy and Motion
Third grade students are exploring energy and motion. To help them visualize these concepts, they analyzed images of golfing, roller coasters, and weightlifting and discussed which image represented the use of the greatest amount of energy. Following the visual analysis, they conducted an experiment in which they released marbles down an inclined plane and measured the distance the marbles traveled. Afterward, they considered ways to make the marble travel further – would increasing the slope of the inclined plane or using a heavier marble work? The experiments continued!
