Grade Level: 6th - 12th; Type: Physical Science, Engineering
The goal of this project is to create a protective device to keep a raw egg from cracking during free fall.
- What happens when you increase the free fall distance?
- How does "padding" an object work?
- Carton of eggs
- Yard stick/Measuring Tape
- Various Supplies for creating a protective device.
- Brainstorm on various ways to protect the egg from cracking.
- What kinds of materials are used in safety devices for sports and automobiles? Think of the materials that we use to protect ourselves in various situations.
- Photograph and document your design.
- Two foot free fall: Using a yard stick or measuring tape measure a distance of 2 feet from the floor. This is the first height at which you will test your device. Calculate the acceleration at 2 ft.
- The egg drop: Cover the floor with plastic for easy egg clean up. Using a yardstick hold your device, with egg, so that the bottom is 2 feet from the floor. Drop the egg by releasing your grip. Do not throw the egg down.
- Did your device work?
- No - you need to do some tweaking. Photograph and document the changes you made. Why did you make that change?
- Yes - Move on to step 4.
- Now drop the egg from 3 feet.
- Continue testing up to 6 feet, increasing each drop by 1 foot.
- What happens as you increase the free fall distance? Did you have to improve on your design?
Terms/Concepts: Free Fall; Gravity; Acceleration; Velocity; Force; Shock Absorber; Damping
