The 2nd Annual CHS Cardboard Canoe Challenge!

• Define the Problem and Brainstorm Solutions - State the problem you are designing a solution for. List at least 20 ideas you have regarding your solution

•  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

Rules of the Road

what Criteria (rules) would you add to the Mousetrap Racecar Challenge to help "level" the playing field?

• the use of rubber bands is either used by all the teams or none of the teams
• a specific number of parts is give to each team to create a car
• all cars have to go through a series of obstacles

Simple Machine Challenge pt I - Mousetrap Racecars!

my team earned 7 achievements


Criteria:Design, build and compete with a Mousetrap Race car (A "car" uses at least two axles).
Maintain a clean workspace.



Constraints:
One mousetrap
No more than 12" of masking tape
Fischertechnique robotics parts
No more than 24" of string
You must work through the stages of the event (see Achievements below)
Additional materials by Instructor approval



Achievements (by stage):
Post your results for the Simple Machine Challenge pt I to your blog. Tally your total number of Achievements earned and justify each within the post. Your grade is the total number of Achievements you earn curved against the number of Achievements your classmates earn.



1)

 Build:"Build It" - Build your design. Document it with a photo.

"The Price of Glory" - If each part you use costs $1, generate a total cost for your build (This info will be used to generate "cost" data to add a pricing element to the game next year).

• our car generated 25$ dollars
• had 25 parts

2)

Test (Compete):Each car will compete on its own. Everyone will take 3 turns and use their best result. Cars are evaluated on acceleration and total distance covered. Generate your design accordingly.

• our car went a total of three squares          1sqauer equals 30centimeters
• second try it went 20 squares                     equals  600 centimeters 
• third try it went 21squares                          equals 630 centimeters   

3)"Competitor" - Compete in the 2nd Annual Mousetrap Race car Challenge.

our final tally was 21 a grand total of 630cedntimeters

4)

Feedback" - Collect feedback (at least one each of +, change, ? and !) from yourself or your classmates.

• +: had the fastes acceleration time
• delta: less wight, more compact and more string
• !: axles need to be smaller
• ?: why did we have are body so low to the ground

5)  Clean Up:"Leave It Cleaner Than You Found It" - Did you leave your workspace cleaner than you found it? Explain.

• cleaned up all parts 
• broke down all parts 
• left workspace as found

 6)Reflection:"Design/Build" - What is a "Design/Build" process? How did your experience with this challenge relate to that? Why might you experience this in a career related to technical innovation?

• the 12 step process
• ideas
• designing
• prototype
• final product
• can be used in a technical inovation enviorment 

Emergency Preparedness!

Define the Problem


prepare for natural disaster or attacks

Examples:

• tsunami
• wildfire
• earthquake
• biological attack
• terrorist attack
• epidemic
• flooding
• power outage

I can relate to the Californian wildfires of 2003 because i was 7 years old and I remember my parents talking about how close the firers were to my grandmas house and how they had to evacuate.
