Who can help the
Objective:

Device building
materials
You can use any materials that you want. Feel free to ask if you want to borrow something.
Rules
- There are no restrictions on what materials you use to construct the device.
- Your team will be allowed 2 practice eggs (you may bring your own eggs).
- The egg will be dropped by you and cannot be altered in any manner.
- You are responsible for dropping the egg so it hits the landing zone. (towel on the floor)
- Find the mass of your egg and device and measure the height of the drops.
- Egg must be able to be removed from device and returned in same condition as received.
Scoring (50
points for drop)
A – Egg survives the fall from the balcony intact 1st try
B+/A- – Egg survives the fall from the balcony intact 2nd try
B – Egg survives fall, but is cracked
C – Egg does not survive fall, but design was well thought out
F – Project not completed or done
*Extra points for additional height from base of balcony
*Best Height to Mass RatioàWINS!*

The teams will design a website in Google. The website needs to have a minimum of 3 pages, including the main page, all pages must be linked together, all pages need to have a title, and the web pages need to be organized and easy to read. Be sure to answer the following questions: discuss the success/failure of your tests; what worked in your design and what didn’t; would you make any changes in your design if you had to do this again; and explain why you choose the materials/design that you used. Also include the following data for the engineers. Explain how you arrived at your answers. The website will need to include at least one photo of your design. Make sure to be CREATIVE!

Who will build the softest landing zone?
Objective:
NASA is looking to design a space vessel that will transport a human to Mars and safely land on its surface. Your design team has been hired to build a model landing zone for the transport vessel. A jumbo egg will be used to simulate the Mars transport. Your goal is to design a landing zone that will keep the Mars transport from cracking when dropped from 3 different heights.
Mars surface building
materials
1 aluminum roasting pan (provided by Mr. D)
Rules
- There are no restrictions on what materials you use to construct the landing zone.
- The materials you use must fit inside the dimensions of the pan provided.
- Your team will allowed 2 practice eggs.
- The egg will be dropped by you and cannot be altered in any manner.
- You are responsible for dropping the egg so it hits the landing zone. No third chances!
- Find the mass of your egg and measure the height of the drops.

A – Egg survives the fall from the balcony intact 1st try
B+/A- – Egg survives the fall from the balcony intact 2nd try
B – Egg survives the fall from the ceiling intact
C – Egg survives the fall from the desk intact
F – Project not completed or done ***Points will be deducted for rule violations.***

We will spend 2 class days handing out materials and working on the design. Drop day will be announced at the start of the project. This project will require design and testing time outside of the classroom.
Who will build the lightest transport and
still survive?
Objective:
NASA is looking to design a space vessel that will transport a human to Mars and safely land on its surface. The cost of using the actual building materials is too great so your design team has been hired to build a model transport vessel with building materials that have similar properties as the actual materials. A jumbo egg will be used to simulate the human. Your goal is to design a vessel that will keep the egg from cracking when dropped from the balcony in the gym.
1 gallon plastic milk jug
1 raw jumbo egg
6 sheets of paper
1 foot of duct tape
Rules
- The vessel must be made only with the materials provided. You may change them as you see fit.
-Your team will allowed 2 eggs, 3 jugs, 18 sheets of paper and 2 feet of tape for design & testing.
- The egg can not have anything physically attached to it.
- I must watch you place the egg in the vessel and remove it after the drop for inspection.
- The vessel cannot exceed 13” in any direction before the drop so it will fit in the launch vehicle.
-Find the mass of your vessel before dropping and measure the height and time of the drop.
Scoring (50

A – Egg survives the fall from the balcony intact 1st try
B+/A- – Egg survives the fall from the balcony intact 2nd try
B – Egg survives the fall from the ceiling intact

We will spend 2-3 class days handing out materials and working on the design. Drop day will be announced at the start of the project. This project will most likely require design and testing time outside of the classroom.
Who will build the lightest transport
and still survive?
Objective:
This is a project to be done in pairs or alone. You are to build a transport vessel for an egg so that it can survive, (does not crack or break) a drop from the balcony in the gym, or the ceiling or the lab table.
Scoring (50
points in the lab portion of your grade for the drop only)
A – Egg survives the fall from the balcony intact 1st try
B+/A- – Egg survives the fall from the balcony intact 2nd try
B – Egg survives the fall from the ceiling intact
C – Egg survives the fall from the desk intact
F – Project not completed or done ***Points will be deducted for rule violations.***
Materials
1 gallon plastic milk jug
1 raw jumbo egg
10 sheets of paper
1 foot of duct tape
Rules
- The vessel must be made only with the materials provided. You may change them as you see fit except that the main transport must be 1 gallon jug.
- You do not have to use all of the paper or tape.
- Holes can be cut in the jug to allow you to put the egg in the vessel. Cutting it in half is also allowed.
- I must be able to watch you place the egg in the vessel and remove it after the collision for inspection.
- The vessel must not exceed 13” in any direction and be at least 8” high at any point during the drop.
- If you build the
lightest design that survives the drop from the balcony you will receive
breakfast or lunch from McDonald’s!

Fill in the table below by measuring the drop height and drop time. Use the Conservation of Energy, Work-Kinetic Energy theorem, Newton Laws, and the definition of acceleration to help you calculate the values. On a separate sheet explain and show how you arrived at your answers. A separate spreadsheet may be used if so needed.

Post Drop Analysis (10 points)
Discuss the success/failure of your drops. What worked in your design and what didn’t? Would you make any changes in your design if you had to do this again?
Timeline
We will spend 2-3 class days handing out materials and working on the design. Drop day will be announced at the start of the project. Make sure and clear your design before proceeding so you don’t have to start over. This project will most likely require design and testing time outside of the classroom.
