Videos of Olympic bobsled races are shown in class. (another here.)
Students are given white paper and strips (2X9) of teal paper that they make 7 snips in. They bend the snips every other way to form tabs and glue it to the white paper. Glue the bottom of each tab then hold one section for 10 until it's glued. Then move the rest of the "worm" in position and hold the end for 10.
