This version of the project is intended to emphasize the iterative nature of the engineering design process. Students might only get one chance-if your egg breaks, you are done.
Egg drop contests frequently reward students whose eggs survive drops from the highest height. Your students will use readily available materials to build a device that can protect an egg during a fall. Each iteration uses data from previous tests to meet all of the initial requirements.įigure 1. If the solution does not meet all the requirements then another solution is developed and tested. If the prototype / solution meets the requirements then the results can be shared. A prototype of the solution is built and tested.
Requirements are specified and a solution is chosen. The process begins by defining a problem and completing background research on the problem. Structures can be designed to serve particular functions by taking into account properties of different materials, and how materials can be shaped and used.Ī flow chart shows the engineering design process.

Students build a device to protect an egg and prevent it from breaking when dropped. The egg drop project is a time-honored tradition in many science classrooms.
