Ziplines- Engineers at Work

Second grade scientists study force and motion throughout the year. In this lab, the engineers used the Engineer Design Process (Ask, Imagine, Plan, Create, Test, and Improve) to construct ziplines with a holiday twist. They were challenged to create a zipline to help Santa or one of his elves move safely and quickly from the rotunda down to the first floor. Three tables were filled with available supplies. The ziplines moved on fishing line. Every Santa arrived safely (although some upside down)! Oh what fun! We ran out of time to retest our ziplines on a piece of yarn which would have produced greater friction.

Make a zipline over the holiday break! What could you deliver?
