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).
- Our boat remained afloat during the whole competition along with another teams.


Balance Master - Awarded if you can have at least one person stand for 5 seconds in the boat (you must conduct this away from the edge of the pool so that non one falls over and hits their head)
- Connor masterfully completed this challenge

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.
