Nearing the end of our transportation engineering unit, fourth graders finished testing the Maglev models. Students had to consider the direction of the magnets and the weight of the passengers above. Ultimately, no passengers could escape the train when the Maglev stopped. Safety was their #1 concern as transportation engineers!
8. Improved Maglevs!
