Big Brain - The individual student with the most brainstorms listed will earn a bonus achievement.
Criteria & Constraints - Sketch Ideas 
Prototype Ideas -


Select an Approach - Generate feedback (+, change, ?, !) and make a decision matrix regarding your sketches/prototypes. Specify the approach you've chosen and justify your selection.



Build Achievements:
Build It!

Test Achievements:
The Fastest - Awarded to the first team to reach the far side (25yds)

- Our team absolutely demolished the others in completing 25, 50, 100, and even 200 yards.


The Farthest - Awarded to the team that can travel the furthest (laps)
- Our team completed the most laps as well (8 laps).


The Longest - Awarded to the team with the watercraft that floats the longest (multiple teams may be awarded this achievement if multiple boats remain afloat at the end of our competition period).

Reflection Achievements:
Feedback 
+ - Very Fast
   - Buoyant
   - Somewhat Stable
Change - Simpler design
              - Reinforced walls
? - How much did the side flotation devices help?
   - Was it necessary to cover part of the front top?
! - Double check everything
  - Great building block piece of cardboard

How Low Did You Go? -
- Our Boat went about 3 inches beneath the water, which was surprising. The unit weight of water is 62.43 lb/ft cubed. And Connor, our captain, weighed around 130 lbs.

Redesign 
- If we were to rebuild our boat, I would definitely make sure it is COMPLETELY covered in duct tape to prevent any types of leaks, and might create a more simplistic design similar to a WWII deployment craft.


- Rack Up Those Points! - The group that obtains the most points in the blindfolded, kick-board finding game get this achievement. 

**USS IHopeIFloat obtained 8 points in the blindfolded, kick-board finding game. The most out of our period.
