As the school year came to a close, two rising juniors prepared for a three-week trip to Africa to study thermodynamics at the University of Botswana. Once they arrived, they learned plenty about engineering and also helped make the sport of tennis accessible to children in African villages.
Biomedical engineering students Ben McClarren and Dan Hageman joined a group of 24 Case Western Reserve University students in the Republic of Botswana, where they took the class “Thermodynamics, Fluid Dynamics, Heat and Mass Transfer,” taught by chemical engineering faculty members Daniel Lacks and Mohan Sankaran.
About a week before departure, Lacks, an avid tennis player, suggested to McClarren and Hageman that they bring along a few tennis racquets along so they could play tennis while there and then donate the racquets at the end of their trip.
McClarren, a member of the Spartan men’s tennis team, and Hageman, who played tennis throughout high school, jumped at the chance—and completely exceeded Lacks’ expectations: With just a week’s notice, they held a donation drive, to which members of the tennis team gave their old equipment and head coach Todd Wojtkowski donated T-shirts, tennis balls and racquets. Their efforts collected more than 75 racquets, 150 balls and a tennis net.
“While the racquets might be considered junk sitting in people’s basements here in the U.S., they are valuable items in a country where 50 percent of the people earn less than $2 per day,” Lacks said. “Many of the racquets were high-end $200 racquets just a few years ago, before new models came out to supplant them.”
