I Earned Achievements
1) Built It
2) Sketch It
3) The Videographer
This was the start of one of our 7 laps.
4) Select An Approach
(+) - Our design has several different approaches .
(-) - The design was somewhat flismy and had some water can easily get into it.
(?) - Which concept has the least faults?
(!) - The flat box might be the best.
5) Criteria & Constraints
Criteria: Build a boat
Constraint: Only use cardboard
Constraint: Only use duct tape
Constraint: Cannot be bigger than the classroom door
6) The longest
7) Define the Problem and Brainstorm Ideas
Problem: We are trying to design a boat out of only cardboard and duct tape
1. Lightweight
2. Sturdy
3. Completely covered in tape
4. Tall sides so water can't get in
5. Large surface area
6. Not too heavy
7. Strong enough to hold a person
8. Not too big
9. Leave no holes
10. Build v-bottom
11. Don't stand on it for too long
12. Don't splash or water will get in
13. Don't shift weight quickly
14. Measure the width of the door for size
15. Use a ruler when cutting cardboard for straight edges
16. Use precise measurements
17. Be careful with the knife
18. Don't bend the cardboard
19. Remove air bubbles while taping
20. Don't bend tape and make precise tape placement
8) Create Your Own Achievement: Make a Rope
9) How Long Did You Go?
Our boat lasted about 40-45 minutes. No, it wasn't surprising when our boat went down because the cardboad was completely wet. The pilot weighed about 95 pounds. Our depth was roughly half a foot.
10) Feedback
(+) - Our surface area worked out really well.
(Change) - I would cover the corners and little spots where water got in.
(?) - Would a V-Shape design had been better?
(!) - Having more ductape around key spots would have stopped water from getting in.
The simple design worked well to our advantage.
The weight of the pilot was benefitial.
We could have built sides more well built.
A paddle could have been a lot better to get around.
We got a lot of water in our boat.
Taller walls would have been better.
