Egg Drop Lab

The Egg Drop Lab requires teams to design and build a device that protects an egg from a 2.7 m fall using limited materials. Students must complete pre-lab questions, conduct multiple design tests, and analyze results to improve their designs. Post-lab questions focus on the physics concepts of force and momentum related to the egg's survival upon impact.

Egg Drop Lab

Purpose: Your team’s egg has to survive a fall from the top of a ladder (2.7 m total) with no cracks
in the egg shell.

Instructions:
A.​ Work in lab groups of no more than 2.
B.​ Complete the pre-lab vocabulary and questions first.
C.​ Constraints:
a.​ 10 cm tape
b.​ 2 pieces of paper
c.​ 3 straws
d.​ 1 egg
e.​ string
f.​

D.​ No Parachutes, No gliders!


E.​ Design, build, and test multiple designs, improving each one with what you learned from
testing the previous one.
F.​ Complete the post-lab questions.

Pre-Lab Questions:

Vocabulary:
1)​ Momentum: how much force something can exert on another object, mass in motion at a constant
velocity
2)​ Momentum Equation: p=mv
3)​ Force Equation: F=ma
4)​ Acceleration equation: a=F/m
5)​ Mass: m=F/a

Vector Diagram Questions:


1) Draw the Force (red) vectors on the egg at the moment it is dropped.
2) Draw the Force (red) vectors on the egg at the moment it hits the ground.

​
Egg Saver Designs
1)​ Design your egg saver device.
2)​ Build the egg saver device.
3)​ Re-design your egg saver device
4)​ Repeat from step 1 for design #2 and #3.

Design #1

Height of Device

Mass of Device

Picture of Egg Saver Device Performance Notes: (compare to #1)


it survived so it's still the same
Results: we dont have the data
Design 1 max drop height __________

Design 2 Max drop height __________

Best Design Results: we dont have the data


Height of saver device (from the ground to the top of your device) __________

Mass of saver device __________

Max Egg drop Height (from the top of your device to egg drop height) __________

SCORE: Max egg drop height / saver device height ___________

Post-Lab Questions:​ F=(mvf-mvi)/t

1)​ Which variable were you focusing on to save the egg?


force

2)​ Why did you focus on that part of the equation, what did it do to other parts of the equation?

because reducing the force would decrease the collision on the force
3)​ The egg has a mass of .25 kg and hits the ground with a velocity of 10 m/s. What would be
the impact force if the egg takes 2 seconds to come to a stop?
0.25*10/2=1.25

4)​ It takes 20 N to break an egg with a mass of .2 kg. If the egg hits the ground at a speed of
5m/s, what would be the minimum time of impact to ensure that the egg will survive?
20N= 0.2*5/x
20N= 1/x
x=0.05
