Gravity Racers

Science and Children—March 2010

With the 2010 Winter Olympic Games prominent in the media, children were exposed to images of athletes skiing down snow-covered slopes, coasting furiously on bobsleds, and skating gracefully across the ice. Therefore, the authors capitalized on their children’s natural curiosity about the world around them by exploring the concept of motion in a weeklong series of science, technology, engineering, and math (STEM) activities in which they design and build a gravity-powered car using the 5E learning cycle model.
