Students in the IMSE 382 manufacturing course really delivered for the holidays.

You have to hand it to Assistant Professor Georges Ayoub for finding ways to make engineering education both rigorous and fun. A couple semesters ago he had his students concept, design and manufacture original board games a highly detailed process that involves a surprisingly wide range of skills in the engineers toolbox. He got such good feedback that this year, he decided to up his game with a follow-up project in one of his manufacturing classes. The challenge: build STEM learning toys and then gift them to the Dearborn Toy Library, a local nonprofit that lets kids checkout toys, including many educational ones. 

Ayoub hatched this plan with Executive Director Mary Gladstone-Highland, who co-founded the toy library with her son a few years back. (Ayoub also serves on the board.) She says theres a ton of interest in STEM toys nowadays, but theres often a perception among parents that theyre prohibitively expensive. Shes not sure if thats actually true or if other, flashier, highly marketed toys are just better at attracting kids attention and parents credit cards. Regardless, that makes STEM toys a great fit for the toy library. Since folks can borrow them instead of having to buy them outright, it stretches families budgets and creates a lot more access to educational toys.

Making a bunch of STEM toys and gifting them to the library sounded like a great idea, but Ayoub admits he wasnt sure what they were going to end up with. The process of not only designing, but building a finished toy that a kid is going to enjoy, not hurt themselves with, and also not break in two minutes is a pretty tall challenge for a single semester. Students would have to quickly work through the design and prototypes phases. And then theyd actually have to manufacture a finished product which would involve learning to use various manufacturing systems in our MSEL lab, including 3D printers, welding equipment and woodworking tools.

As it turned out, Ayoub didnt have anything to worry about. The students came through with some pretty amazing, sturdily built toys that he calls beautiful and thoughtfully designed. One team created a version of a   a classic STEM toy that dates back to the time of the Greek mathematician, physicist and engineer Archimedes. Jacob Gaudette and his partners chose another classic  . The line of metal spheres is strung and suspended from a small scaffold such that when you draw back the sphere on one end and release it, it strikes the others, sending the one on the opposite end flying and setting off a chain reaction of collisions. I mean, I have a handle on the physics of what makes it work; weve studied all that stuff in our classes, Gaudette says, referring to principles like the conservation of energy and conservation of momentum, which the cradle demonstrates really clearly. But you see it happen and it still looks like magic. I would have loved to have that toy as a kid.

For Isabella Luckey, the toy challenge was serendipitous. She actually works for a nonprofit educational lab in Ypsilanti, where her job is building up a roster of STEM toys for their educational programming. For their class project, she and her partner set their sights on a from-scratch build of a pull-back wind-up car. It zooms forward when you release it, and since it was intended as an educational toy, they designed it without a frame so kids can see the springs and gears that make it work. During their design process, they ran into several challenges that required some quick problem solving. In one of their early prototypes, for example, they discovered if a kid wound the car forward instead of backward, it could break the spring powering the car, which inspired a little reengineering. And Luckey says they figured out
