I am claiming 9 achievements.
Design Achievements
X• Define the Problem and Brainstorm Solutions -
Sinking : Keep whole thing ductaped
add extra support.
add flotation device design
X• Criteria & Constraints - List or reference the specified Criteria and Constraints you're designing for.
A boat to float across a pool.
XList at least one implied criteria. List at least three implied contraints.
1.Floating
1. time
2. materials
3. partners
• 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 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.
X• 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.
Specification & Justification: I have chosen the approach to treat the cardboard canoe as a stock-racing car and make it as light & aerodynamic as possible.

X• 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?
s=surface area
d= ducttape
a= amount of rolls
d * a = s
1.89in X60.1yd)=
618.408in = 1 role
618.408in X 4rolls =
2473.632in. (68.712 yd.)
I think I could have achieved 50% efficiency with the overlapping.
Build Achievements:
Test Achievements:
X• Balance Master -Zola "surfed" the canoe.
X• Videographer - Take video of the challenge and post to your blog.
X• How Low Did You Go? - How low in the water did your canoe sit (roughly)? Was it surprising how little your boat went down in the water? What is the unit weight of water in pounds? How much did your pilot weigh (roughly)? Use math to help explain the depth that your boat sat in the water:
Our canoe sat roughly 3 in. in the water. It was very surprising how little our boat went in the water.
It is converted from 3 in. of water to 0.11 p.s.i.(per square inch). Wyatt Zola our pilot weighs 95 lbs.
X• (Make Your Own Achievement) - Make an achievement of your own design that you can award yourself for something awesome your team did. (Example "Transformer" - although our canoe sunk, our team was able to convert it into a surfboard style design and continue competing!):
"The SUPER Digital Media Achievement" for getting multiple members of our canoe's crew to capture the event in digital media.
Reflection Achievements:
• Feedback - Generate ten items of feedback for your effort (from the design/build process and/or the actual product). Make sure you include at least one item of feedback in each of our four feedback areas (+, change, ?, !)
• Redesign - If we were to do another Cardboard Canoe race next semester, what would you build? Draw from everything you experienced in your class and propose the most competitive solution. Include a sketch with key features and dimensions labeled:
