Mertz stipulated that the toys be designed for use anywhere in the world, including communities in underdeveloped countries. That meant any electrical components of a toy would have to be capable of being powered by hand-crank generators or solar-energy cells.
Mertz’s class of aerospace, mechanical, chemical and electrical engineering majors teamed with 30 sixth-graders from the K-12 ASU Preparatory Academy, relying on the youngsters for insights on whether the toys being designed would be both fun and educational.
The ASU students visited ASU Prep, where they helped the sixth-grade class perform a design activity to demonstrate some fundamental principles of engineering. Later came interviews between the two classes of students, documents describing proposed toy designs, written feedback on the designs from the sixth-graders, and a progress report meeting on Skype between the two groups of students.
The collaborative endeavor culminated with Toy Expo day. The sixth-graders visited the mechanical and aerospace engineering machine shop on ASU’s Tempe campus – where they got a look at a high-tech computer-controlled milling machine and a three-dimensional printer – before meeting the engineering class at the campus eSpace workshop. There, the youngsters examined nine toy and game prototypes developed by Mertz’s students.
Designs ranged from a solar-powered device that would light up when the correct answer to a question is given, to a catapult that throws a ball at a target if the throwing arm is set to the correct length based on correct answers to board game questions that teach the geologic time scale.
Another design required solving math problems to enable players to progress in a game called Math Monkeys, which featured hand-molded clay monkey heads as game pieces.
There were also variations of popular games like Jenga and Guess Who? adapted to incorporate math topics like prime numbers and decimal division.
“Working with ASU engineering students was an exciting and challenging opportunity for my students,” says ASU Prep teacher David Bennett. “We want to see our students graduate from college after they leave us. This project certainly helped to further that goal. It showed them in a very real, hands-on way the possibilities that engineering, science and technology can offer.”
Mertz now has an eye out for “opportunities for partnerships with organizations or companies that would help get these designs into classrooms around the world.”
The project achieved his immediate goal of giving his students experience in “reaching out to our local community and encouraging younger students to pursue college degrees, and considering the global impact that engineering can have,” Mertz says.
“It really represents the kind of impact we want our students to have while studying engineering at ASU,” he adds. “We want our students working to solve real engineering problems from day one.”
