Suppose you need to design a parachute system to help a remote camera land safely at the bottom of a cave. The camera will drop from a height of one story. It has a mass of about 500 g. A carton of eggs inside a box will model the camera. For your test to be successful, none of the eggs can break when the box lands. You may use string, plastic bags, paper, and any fabrics you have to make a model parachute. Identify the criteria and constraints. Describe your model and draw a picture of it. Describe how you could test your model and what you would do after the first test.
