cardboard canoe challenge

Cardboard Canoe Challenge

Total Achievements: 12 achievements accomplished

 

Problem-

1. roll up cardboard
2. make cardboard rolls large for more buoyancy
3. more surface area
4. double layer perpendicular rolls
5. go to recycling depots to get free cardboard and have an ample supply
6. duct tape individual rolls to make for water tightness
7. inspect rolls for clean and smooth taping
8. consider testing raft in outside pool to see if raft/boat will withstand water and float
9. build boat to common house design, square bottom and triangular top
10. build boat with thin walls to reduce supplies
11. let raft walls be open so water can freely go in and out of raft
12. duct tape every part of raft
13. use outriggers for balance and buoyancy
14. narrow body for speed through water
15. duct tape inside of boat
16. make duct tape rope to pull boat/raft
17. duct tape paddles
18. inject helium for more buoyancy (if air tight)
19. V shaped bottom
20. flat bottom
21. make outrigger arms out of strong cardboard so they don't bend under pressure
22. make outriggers bigger than actually boat so they keep the boat out of water more easily
23. make outrigger design hull deep so that it can hold more weight and put less stress on outriggers
24. put outriggers close to boat to ensure they get best results
25. put outriggers directly on boat
26. put outrigger at 3/4 height of boat wall so that it helps keep the boat from dipping to much into the water
27. use outriggers on flat bottom design
28. use weekends to gainmore building time
29. learn what worked and didn't work from the previous cardboard canoe challenge
30. come up with as many variations to have the best idea of what might work and possibly combine some ideas
31. treat every idea as if it is plausible
32. study some of the best light boat designs used in the commercial industry
33. found out what duct tape works best in water (some have different types of water resistanceand stickiness
34. consider pushing rather than pulling raft or boat

 Constraints- only cardboard and duct tape

                    - 3in" sidewall

Test Achievements-

• Balance

 

-longest

Reflection Achievements-

• Feed Back

- the duct tape rope helped us get across the pool
-it floated

-neater taping, water doesnt leak in-probably needed more/bigger rolls of cardboard

 

-shouldve checked better for places where water coulve possibly leaked in

• Redesign-

-If we did another race we would probably go with the outriggers design that I had shown in one of my sketches and worked from that idea with the knowledge of what happened on this race.

• Make Your Own Achievement-

Submarine- Submerge your boat completely under water and bring it back up, if its still able to float then you have completed the challenge.
