Cardboard canoe challange

At the end of the race, I earned: 10 achivements 
• Sketch Ideas - Draw 3 different sketches for possible designs. Label at least 3 key features for each sketch. Describe the feature's functionality so a viewer understands why the called out feature is important.

  

Boat #1: Has a stable design. Not a completely flat bottom(almost like a v shape but not that much) and has a big base that can fit one to three persons.

Boat #3: Tall walls so water wont come in. Can cut thru water.Stable design.

• Prototype Ideas - Craft physical prototypes (models) of each of your three sketches. Use a note card or post it note to call out at least one key feature on each model. Post the images to your blog and describe the key feature that you've pointed out on each.


Has a big base, but not completely flat, this boat has very good Resistance, and can carry up to four persons.

Has large paddles: Helps gains speed and helps balance canoe.

Has good buoyancy: has a flat and stable bottom that can fit up to two people.

• 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.

Design 1(Ruy):

+: It floats well on water
-: It does not have anything to break water Resistance

?: Will it go fast?

!: Put paddles

Design 2(Michael):
+: Its stable

-: To big

?: Will it be effective in the race?
!: Add paddles

Design 3(Armando\Stanley):

+: It can break thru water
-: Not as stable as others
?: Will it sink?
!: Add side support to help with the buoyancy

• Use a decision matrix to compare your 3 design approaches (we'll talk about decision matrices in class)

Best 10 worst 1

The design that we actually used for the race was the first design.
Design 1(Ruy):
+: It floats well on water, and is very buoyant(could hold up to 4 persons)
-: It had a few leaks that got water onto the boat, and made it heavier.( But it never sank) 

?: If we would have had more "horsepower" would we have won?

!: Put paddles, and perhaps put a bigger piece of cardboard (not attached) under it to give it a good start. And Put more duct tape on the corners and edges.

Achievements

Design Achievements
• Define the Problem and Brainstorm Solutions - State the problem you are designing a solution for. List at least 20 ideas you have regarding your solution.

The problem was that we had to design, and build the fastest and most resistant boat we could by using duct tape and cardboard,

Ideas:

1. Make it big
2. Put paddles
3. Stable walls
4. A lot of duct tape
5. Duct tape rope
6. Not straight on the bottom
7. Stable base
8. Equal size walls
9. Make it float
10. Set as much buoyancy as possible
11. Dynamic
12. Mermaid at the side
13. Artistic design
14. Big stiff cardboard cylinders to hold walls
15. Put cylinders on front and back
16. Use cylinders to hold front part and back part of boat as well
17. Seal corners with  a lot of duct tape
18. American flag on top
19. Stable walls with duct tape
20. Get the stiffest pieces of cardboard possible

 
• Big Brain ?

• Criteria & Constraints - List or reference the specified Criteria and Constraints you're designing for. List at least one implied criteria. List at least three implied contsraints.

• Criteria implied: Your boat must float at least one student thru the course of the competition
• Constrains implied:
• You may only use Cardboard and Duct Tape for this event.
• Each boat must have a minimum of a 3" tall "sidewall"
• All exposed cardboard must be covered in duct tape (this will reduce cardboard disintegration in the pool).

Build Achievements
• Build It! - Build your watercraft. Document it with a presentable photo.


Test Achievements
• The Fastest - Awarded to the first team to reach the far side (25yds)
We were not the fastest, but we got second place on the race.
• The Farthest - Awarded to the team that can travel the furthest (laps)
We didn't go the furthest, but we could have gone more 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).
Every team got this achievement.
• 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)
I did achieve this, i was able to stand in it for 10 seconds.
• Videographer - Take video of the challenge and post to your blog.
