"Project Egg Drop" Goal Design and build a container that will protect delicate cargo (an egg) under stressful landing and accident conditions. Suggested Materials (just a sample of possible materials) Key Question Based on the fragility of an egg, what materials  8 1/2 X 11 paper and design concepts need to be considered to  Tape protect an egg during a drop from over 3 m?  Cardboard  Balsa wood Preparation  Rubber bands Collect Possible Materials  String Construct a container to protect the egg from a fall  Feathers of over 3 m  Glue  Straws Required Materials  Plastic wrap  Bubble wrap  Toothpicks  Egg (provided by teacher)  Cotton balls  Measuring tape  Marshmallows  Stopwatch  Container to protect egg Questions to Think About Should your container be made rigid; or is it better if it Construction collapses? Should the egg be able to move, or should it be held  The device must be of original design. immobile?  It can be constructed of any material that the What types of materials or structures will absorb the team feels appropriate and can obtain, shock of an impact? including material recycled from other How can it be designed to withstand multiple drops products. from successively greater heights?  Upon the initial release of the device, it must What types of materials will contain the egg if it be able to fit within a 12" cube.
