The image in this problem is part of a piece of equipment found in the playground of a school. How would you describe it to someone over the phone?
Many natural systems appear to be in equilibrium until suddenly a critical point is reached, setting up a mudslide or an avalanche or an earthquake. In this project, students will use a simple. . . .
