Zip, zip as fast as you can, you can’t catch me, I’m the Gingerbread Man…
Students create a zipline, attach a straw trolley to an Elf, and design a Gingerbread Man. The STEM challenge was to make the Gingerbread man faster than the Elf. Students thought of adding mass, increasing the angle of the zipline, and giving the Gingerbread man a push.
