Egg Drop Lab Notes
Methodology
Day 1
We will be having a classic egg drop competition. After the lecture, organize yourselves into teams
of two or three. Each team will be allocated ₳100 (Anderson bucks). After teams are organized,
the market will be open! The market will contain materials that you may choose to buy and use in
the construction of your Egg Protection Device. Here are some tips to know about the Free Market
and competition:
●
Prices will fluctuate during the course of the day, so buy and plan quickly and buy early.
As supplies run low, prices will increase.
● Be on the lookout for possible investors! Your TA and Mr. Bustos have an additional ₳50
to give out as they wish!
● Engineers work in teams, and each team member has specific roles. It may be helpful
to assign roles to each member of your group, e.g. economist, researcher, and designer.
● Taxes and fines will be collected! Your TA and Mr. Anderson have the authority to issue
taxes and fines to specific groups. The taxes and fines are as follows:
○ Bad Attitude Fine: if you have a bad attitude or display unsportsmanlike conduct
as determined by your TA or Mr. Anderson, you will have to pay ₳10 per infraction
at the end of the competition.
○ Too Loud Tax: If the room gets unreasonably loud, Mr. Anderson will give one
warning. If the room gets unreasonably loud again, each team will be forced to pay
10% of their final wallet.
○ Broken Egg Tax: If your egg breaks on Monday or Tuesday, you will be forced to
pay ₳10 immediately.
● The final construction must fit inside of the sizing box. Before the final drop on Day
2, the box must be able to fit over the top of your construction and rest snuggly on the
table. Failure to meet this requirement will result in disqualification.
● You are not obligated to disclose any information on your ledger to other groups.
However, you must disclose ledger information to Mr. Anderson or your TA immediately
upon request. Failure to meet this requirement will result in a Bad Attitude Fine.
Testing will occur on Wednesday and Thursday. Awards, which will be given at the end of the
competition, are as follows:
● Cheapest construction
● Least amount of weight/mass
● Withstood the greatest amount of force upon impact
● Withstood the least amount of force upon impact

Day 2: Testing and Analysis
Mass of the construction and egg, 𝑚: __________ kg
Drop distance, 𝛥𝑠:
Drop time, 𝑡:
__________ m
__________ s
Analysis
Draw a free body diagram of your construction and egg.
Using the kinematic equation from the lecture and Newton’s second law of motion, calculate (1)
total acceleration, (2) the total force, and (3) the drag force felt by your construction and egg
upon impact. Show your work. You may show your work on a separate sheet of paper.
(Hint: the equation from lecture is 𝛥𝑠 =
