Engineering in Action!
Second graders at Harambee are studying the engineering design process: ask a question, imagine possible answers, plan out how to find the answer, create things that help answer the question, and improve on what you created. On April 19, two professors (one of whom is Mrs. Alford's husband!) and eight biomedical engineering students from the University of Minnesota spent the afternoon in Mrs. Alford's classroom. (They will return next week to work with Mrs. Halvorson's class.) The university students talked about famous engineers and and the different types of engineers. Second graders then asked the question, "How can I create a helmet that will protect a head?" They were given materials to create a helmet and set to work. To test the helmet, students got to hit a red button which made a crash test dummy head fall. An accelerometer measured the impact when the head hit the floor. The score was sent via bluetooth to a computer program, which then projected it on the screen. It was a very fun afternoon!
