Purpose:Design ways to cushion an egg that is thrown through the air. Using the theories behind air bags in automobiles, find the best way to protect it from impact so you can throw it faster and further.
- Raw Eggs (teacher brings)
- Flat bed sheet (twin size works best)
- Two broom stick handle or dowels
- Needle & thread
- Turn under the bottom edge of the sheet about 2 " . Sew the flap up and insert the broom stick handles into the top cuff and the one you have just sewn.
- Have four students hold the corners of the sheet horizontally to the ground.
- Have another student take aim, and throw the egg up and onto the sheet.
- Experiment with different speeds and distances to see how far and how fast the egg travels without breaking.
- What happens to the egg's momentum?
- What would happen if you dropped the egg on the floor?
- How can you cushion the (person) EGG?
- Would that transfer the momentum of the egg?
- Does the size of the sheet make a difference in your project?(What if the sheet is too loose or too taut)?
- Would a parachute attached to the egg provide enough cushion to keep it from breaking?
- How high could you drop an egg attached to a parachute?
