I launched a project just over three weeks ago. This mini-arcade game project (that's why we had such an unusual field trip to Chuck E. Cheese) is truly a STEAM project. Students measured, scaled down, reduced, cut, strengthened, glued, measured again, painted, improvised, weighed, tested, and drilled, all while asking the questions "Is this good? Do I like this? If not, what could I do so I might like it more?" These qualitative questions aren't asked with as much frequency in STEM education. STEAM forces kids to think in this increasingly important way.
Finally, I want to show this little video highlighting the game "Hole in One." It's amazing that students are learning very basic principles of electricity while wiring a scavenged sewing machine motor with a dimmer switch to make their machine functional. Yea STEAM!
