• Add your question:

• How did your team’s blueprints and apparatus compare?
• Did you make any changes after you started to build your apparatus?
• Did the team meet the criteria of success - design trade, criteria, and constraints?
• How much money did you spend?
• What did you choose this material opposed to using something else?
• Are your spacecraft sides no greater than 6 inches?
• How many batteries did you use and why? If you used more than one, how are the connected?
• Why do you think your egg will survive?

Please highlight the specific bullets that the team you are observing completed:

Design Trades

Circuit:

• Safety: More switches allow for safety lockouts.
• Reliability: More switches mean more possible failures.
• Cost: More switches means more cost.
• Convenience: More switches could allow for multiple operating stations.

Spacecraft:

• Protect the egg: Most important goal
• Lightweight: Less weight means a spacecraft can carry more of something else like fuel or people
• Easy access: Should not be hard to get egg in and out

Test Hardware box:

• Portable (for example, foldable solutions are good for transporting)
• Sturdy
• Low cost (Any materials you use that isn't the box would be a negative against cost)

Criteria

Circuit:

• Safe; must not drop egg accidentally or due to a likely failure

Spacecraft:

• Must keep egg safe
• Must include ziplock bag for egg
• Must include steel plate (tin can lid) to hold to magnet

Test Hardware box:

• It needs to be able to hold the spacecraft when there is no power and allow it to be released by the magnet.
• For example, a shelf that slides under would work. It holds the craft until the magnet can hold it and then the shelf is removed.

Constraints

Circuit:

• Limited number of batteries and switches and magnets and each one you use drives up your cost.

Spacecraft:

• Less than 200 cubic inches in volume
• No side greater than 6 inches
• Maximum weight (including egg) 1200 grams

Test Hardware box:

• Dimensions: No more than 3X3x6 feet (width, depth, height)
• Must suspend egg capsule at least 5 feet in the air (may rest on chairs, etc. for height, if desired)
• Should allow viewing of the egg drop via cut out windows
• Use only a box and cardboard along with joining materials like glue, tape, etc. (except, of course, for the electronics).

Any Additional Feedback:

Give this sheet to the team before you rotate 
