What characteristics of the solutions could be combined to form the best solution possible?:
Our waterslide idea and the boys' loop idea.

How did your group's dynamic impact the outcome of your solution?:
It impacted our solution by us not being able to get it finished because the tactic required too much tape.

# data[].attributes.body
Does it contain all required elements?:
-loop
-turn
-must be 2 meters
It does not contain all that's needed

Does it work?:
No

# data[].attributes.body
What is the strongest aspect of your design?:
We got the tape to work

What is the weakest aspect of the design?:
The failed loop

Explain how well your solution meets the criteria and constraints of the design challenge:
It doesn't.

What is working well?:
The marble rolls nicely.

Where are you having trouble?:
We are having trouble with the loop and getting the tape to stick

Plan for tomorrow:
Get work done

What questions have come up, and how did you answer them?:
Q: The tape won't stick
A: Use more tape
Q: Loop is too square
A: Make it rounder
Q: Hill is too steep
A: Make it go down more and up less
Q: Get the turn without the marble falling off
A: Make it like a waterslide

What has worked or is working now?:
Nothing

What modifications need to be made to your solution?:
Make it like a waterslide (in a circle, like a closed tunnel) so the marble doesn't go flying off

Plan for tomorrow:
Make it like a waterslide so the marble doesn't go flying off

We have nothing

# data[].attributes.body
Data Collected:
We learned that square loops don't work because of the sharp corners.

What worked well:
Tape moderation

What modifications need to be made?:
Make a circle not a square on the loop

Plan For Tomorrow:
Make a circle, not a square for the loop, then finish the rollercoaster.

"How did the constraints affect the possible outcomes of the solution?"

# data[].attributes.body
Criteria: a loop, a turn, minimum of 2 meters in length

Constraints: Limited materials, smallest cost

File Folder: $20 per folder-
2

Plan Paper: $12 per piece-

Tape: $5 for 10cm-
40cm

Materials Used:

Final Coaster Cost =

60

# data[].attributes.body
Design and build a paper roller coaster that will transport a marble safely from one end of the track to the other with the smallest material cost. The roller coaster must include a vertical loop, a turn, and be a minimum of 2 meters in length.
