Santa Ziplines

This lab was all about engineering with a Christmas twist! Second grade engineers learned first hand about the forces of gravity and friction when they constructed ziplines for Santa. Their goal was to send Santa from the second floor to the first safely through the rotunda. We didn’t want him to fall out, turn upside down, or get stuck midway. Although he could have a seatbelt or a chair, he could not be tied to his zipline. Collaborative teams had a choice of four tables filled with possible materials. After constructing the ziplines, we tested them. If there had been additional time, we would have compared design choices, discussed results, improved our designs, and retested them to complete the Engineer Design Process. Our zipline was fishing line, but how might our results have changed if we used a zipline of twine or yarn? Make one at home and send me a photo or video.
