Race day is here and the 5th graders used their final pressure plate sensor designs on the track. Based on their analysis of their cardboard prototypes, the final models were made of more durable materials: corrugated plastic on the exterior and disposable baking sheets for conductivity. The video has captions that will hopefully explain a little more. It was a really rewarding project that incorporated computer programming, decimal math, electricity, engineering design… and of course, Social Studies via the Greek Olympics. I made sure to express how proud I was of these young people for sticking with it over these last few months. They weren’t just studying engineering and design – they were actually doing engineering and design. On to the new challenges next year!
