We're Mimi, Haley, Tara, and Lauren, and when we talk about curling, we don't mean hair! Curling, our favorite sport, is a sport in which you slide four heavy rocks down an icy surface at the center of a target. The team with the rock closest to the target's center scores a point. When we release the rock, we give it a little bit of spin, so it curves a little, or "curls." This got us thinking: How does the spin we put on the rocks affect where it goes?
