- build carboard canoe
• 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.
Criteria• Build a watercraft that allows you to traverse the CHS swimming pool.
• Your "boat" must float at least one student through the course of the competition.
• Protect your workspace from damage!
Constraints• You may only use Cardboard and Duct Tape for this event.
• All Staples or other foreign material must be removed from your cardboard. If we trash the pool, we will not be invited back for other activities during the year (yes, we have other activities in mind for 2nd semester).
• Cardboard must meet our quality standard and be approved by the instructor (more info to follow)
• Each boat must have a minimum of a 3" tall "sidewall" (no completely flat designs).
• All exposed cardboard must be covered in duct tape (this will reduce cardboard disintigration in the pool).
• Each team will be provided one "versa table" cardboard box piece and two 60yrd rolls of duct tape. Any materials beyond this (likely need more cardboard) need to be resourced by your team
• 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.
+: · Was the longest to float · Very little water came in · Very stable · Watertight | ?: · Why was the Balance of the boat wobbley |
Delta: · Better oar · More duct tape in the inside of the boat | !: · Way of duct tape layering · Flat bottom · Angled front and back · High sides |
• Build It! - Build your watercraft. Document it with a presentable photo.
• The Early Bird Gets the Achievement - Awarded to the team with the fastest build.
are boat was finished a day before the due date
• The Farthest - Awarded to the team that can travel the furthest (laps)
are boat was the longest to stay afloat and did many more laps in the water
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).
are boat was the longest
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)
joe lee stop in the boat for over 5 seconds
• 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 feedaback in each of our four feedback areas (+, change, ?, !)
+: · Was the longest to float · Very little water came in · Very stable · Watertight | ?: · Why was the Balance of the boat wobbley |
Delta: · Better oar · More duct tape in the inside of the boat | !: · Way of duct tape layering · Flat bottom · Angled front and back · High sides |
• How Low Did You Go? - How low in the water did your canoe sit (roughly)? Was it suprising 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 boat went 3inches down
