3rd Annual Cardboard Canoe Challenge

I earned 14 Achievements on this challenge.
The 14 Achievements include:
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.
Big Brain - The individual student with the most brainstorms listed will earn a bonus achievement.
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.
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.

Prototype Ideas - Craft physical prototypes (models) of each of your three sketches. Use a notecard 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.
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.
Surface area! - Calculate how much surface area you can cover with your given duct tape. How many sf can you cover with one roll? How many can you cover with all your rolls? What % efficiency do you think you can achieve with your overlap?



Build Achievements:
Build It! - Build your watercraft. Your build must meet the standards of construction (100% covered in Duct Tape). Document it with a presentable photo.



Test Achievements:
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).
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)
Videographer - Take video of the challenge and post to your blog.
The Cardboard Canoe Challenge is a competition among teams in which each team builds a boat using only cardboard and ductape. The process of building the canoe started with sketching prototypes and designs that could be built within the building time frame as well as keep afloat once it is on the water. Also, the boat was required to have at least one person inside it while the rest of team either recorded the event or pushed the boat inside the water.

Initially, my group (known as Team 6) brainstormed some ideas that could be used for building our boat. These ideas included:
1) V-bottom
2) Triangle front
3) Ductape rope for towing
4) Slim body
5) Higher side walls on the front for breaking through the water
6) Use least amount of cardboard as possible
7) Lond design so the person in the boat can lie down inside it
8) Cardboard sails
9) Ductape sails
10) Cardboard rutter
11) Low side walls for less drag
12) Overall low profile design
13) Re-inforced front for breaking through the water
14) Cardboard paddle
15) Rounded bottom
16) Added weight to center for balance
17) Re-inforced bottom to reduce leakage
18) Heavy duty cardboard for taking damage
19) Design low side walls so passenger could paddle
20) A worthwhile name

When my group created a small-scale model and tested it with marbles, members from other groups said it was very bouyant. It could hold over 50 marbles before collapsing. Therefore we kept the design, without speed in mind.



We then calculated the surface area of the boat before we built the full scale model to calculate how much duct tape and cardboard we would need.

We built the full scale boat and completed it by the deadline. Once the boat was complete, my group decided on naming it after the last NASA space shuttle to venture into the depths of outer space: The Endeavor.






Then name couldn't have fit any better. Our boat might have not been the fastest, but it could definitely stay afloat for however long required and could hold up to three people in it.
