We visited University of Michigan’s campus during their annual “Xplore Engineering” camp. This multi-day event brings grandparents, parents, and their young scientists from all across the country to lovely summer Ann Arbor for a few days of science and engineering experiential opportunities.(more…)
Failure is an important part of the
Reiterative Design Process!
For some students, dealing with failure can be tough. It’s frustrating to encounter obstacles in science! And for teachers – how do you grade a project when a student puts a lot of effort in, but keeps hitting roadblocks?
Many of you already teach like this, but I wanted to share my own recent example of the Reiterative Design Process. Very few things turn out perfect on your first attempt (like the Orange Chicken I attempted to make last night… Not enough sugar?) and require you to learn from several failures or mistakes.
Many students we are working with now are excited about the growing field of DIY Neuroprosthetics, so to help guide students along in their journey, I’ve been working on creating my own prosthetic hands using materials that are accessible to many Middle and High School students!
Three Generations of NeuroProsthetics

This year, we were excited to release two new kits in concert with our Muscle SpikerBox Pro, kits that are designed to help capture very precise data about reflexes (The Reflex Hammer) and reactions (The Reaction Timer). It didn’t take long for students to start getting their hands on these tools, and we are excited today to present the results of one classroom’s research which was enabled by these tools!
Juli D. and her Anatomy and Physiology class were interested in studying reactions and reflexes, first by studying reaction times in “distracted driving” scenarios, and then by coming up with experimental procedures to see what variables may affect reflexes.
Juli shared a lot of pictures and information about her and her students’ work this summer, made possible by a Michigan education grant from Tri-County Electric! From Juli:
“Tri-County Electric offered us a grant of $2000 to purchase muscle spiker boxes and reaction timers. The purpose was to have students develop a lab that would test how reaction times change with distractions while driving. Backyard Brains graciously worked with us through some kinks and even supplied us with new equipment to expand our research into how reflexes change with different temperatures.(more…)
