 As part of an NSF grant to develop exhibits and teaching aids that illustrate key concepts of calculus, I worked with a group at the Science Museum of Minnesota. To illustrate the essential idea of slope as "rise over run," I decided to use the example of slope when skiing. A computer display in front of Slope Rider lets users enter a slope for Casey (named after my daughter who modeled the pose), and with a whir of gears she rotates to that angle. A laser connected to the board points at the same direction, and there are several goals to try and hit. If the laser lands on a goal, Casey does a flip! Slope Rider now resides in the Science Museum of Minneosta's Experiment Gallery. A couple of pictures from the development process:
