Ah-ha Moment
The freshman seminar “Materials and Technology for a Sustainable Energy Future” culminated with students taking what they learned to the Liberty Science Center in Jersey City, N.J., to teach young visitors about batteries, solar cells and other energy-related technologies. One 3-year-old visitor (below) was particularly excited to see how a battery makes a clock run—a visible payoff for freshmen Colleen McCullough and Ben Siegfried and Craig Arnold (center), the associate professor of mechanical and aerospace engineering who taught the seminar. At right, freshman Jesse Adams demonstrates how a pinwheel, a used water bottle, some wire and magnets can create electricity.
