The 3rd Annual CHS Cardboard Canoe Challenge!

This is the 3rd annual Cardboard Canoe Challenge. Although it as turned into more of a cardboard Barge challange.



Total poinnts/ Achievements: 12


Design Achievements:

Define the Problem and Brainstorm Solutions - The problem is to create a vessel to suport one person from one side of the pool to the other. Our solution was to make a square box with a slanted front. We individually wraped each section of cardboard and then taped the seems together.

Criteria & Constraints -
     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 three 60yrd rolls of duct tape.
       Any materials beyond this (likely need more cardboard) need to be resourced by your team.
 Implied Constraints: You can only have the members from your group work on the craft. Don't mess with other peoples crafts. And you cant lift the boat from the bottem to keep it floating.
Implied Criteria: You can not hold the boat up from the bottem.

Sketch Ideas -


















Prototype Ideas -


Select an Approach -
+ the desine was similar to that of the wining one from previous years
Change the original desine we had was to long so we made the front at a slant to take up less materials
? Use doubble the amount of cardboar to keep it stable
! The decals we did were cool
Surface area!
The total surface area that we could cover with 3 rolls of ductape would be 75ft2. I thought we would use an 85% efficiency.



Build Achievements:

Build It! -



















The Early Bird Gets the Achievement - Our group was the very first team in our class to finish our vessil.


Reflection Achievements:

Feedback -
- the walls were to thing so they folded in
- the desine worked for a wile untill it took on water and started to folld on itself
- the leashes that we used to pull the boat worked for a little wile
- the decals on the back and front were cool

How Low Did You Go? -
Our teem spent a total of 2 laps continusly in the watter before it flooded
Redesign -
I would build a more canoe like ship with thicker walls and maby suports to keep it form caving in.
• How Disformed Can You Go -
Our canoe was severly crumpled up-

Mouse Trap Race Cars


This is the 3rd Annual Mousetrap Racecar Challenge yet it is my first time participating in it. I had a great time with it, with my partner Brett. He was the photographer for both video and immages.

For the front wheels we used CD to redse drag. Each one was held on by two smaller wheels that kept them in place for the most part, they had to be adjusted every now and then. We added a small metal rod to the mouse trap "bar" to increase the length of the lever arm. The rear wheel had the power and had a rubber ring around it to increase traction. We used a total of 35 parts, thats counting every little piece. We got third palce in the distance race and second in the speed race.

Total Points: 10

Design Stage:"Brainiac" -

"Visualize It!" -


Build Stage:
"Build It" -

"The Price of Glory"
- we would have spent $35 on our car, witch is not that much considering that the formula 1 cars can cost upwards of hundreds of thousands of dollars.

"Competitor" - yes we did
"Feedback" - Collect feedback (at least one each of +, change, ? and !) from yourself or your classmates.
?- Why did it have CD's as wheels?
  -Did the CD's help alought or did they not make a difference?
Change- I would have changed the rear "power axel" so that at the end of its run the string would slip off and not tangle up again so that it would stop itself.
+- The CD's make it look really cool.

Iterate Stage:
"Re-work"
-Between our first and second races we added a strawl on the end of the lever arm to extend the length but not the power.

"Game Changer"
-I would change the limit on the tape so that you could use any kind of tape and however much tape you wanted to use. I would do this becasue I found it extreemely hard to do every thing i wanted to do with the limited amount of tape that I had at my disposal.

"Name it"
- Invent a name for an achievement that you think is better than what we have currently.


"Leave It Cleaner Than You Found It" - yes, all the tape we used was thrown away and the piecses we used were put away

Human Centered Design

This was my CAD moddle for our first idea of the podium for Mr. Huang. He asked us to make one that was 4 feet high and 2 inches, he asked us to make it look like his old one that was just a bit too tall.
These were done by Patrick Burke
These were created on Blockland
This was created by Chris Cervantes
                                   
And this wa created by Connor Lewis
                                    
They were both created using Minecraft

This was a group project that we all worked on and we talked to Mr. Huang and this is what he wanted us to make.

Miniature Train 2.3.1a

Linkage Peg
I used a total of 4 Linkage Pegs on my train and they were used to hold the Linkage Arm to the Wheel
Linkage Arm
There were a total of 2 Linkage Arms on the train and they were used to turn both the wheels with only one being powered.
Hitch Peg
The Hitch Peg was used to hold the Hitch Magnet onto the Body of the train, and thier were a total of one of these on the train.
Hitch Magnet
The Hitch Magnet would be used to hold two different trains together and thier was one of these on the back side of the train.
Cow Catcher
Their is only one Cow Catcher on the train and it is used to make shure the tracks are clear.

Axle Peg
The Axle Peg is used to hold the Wheels in place and thier were fore of these.
Stack
The Stack went on top of the Train Body and their was only one of these.
Train Body
The Train Body was the magority of the mass of the train and every thing went onto the body and thier was one of them.
Wheel
Their were 4 Wheels and they are the only things that touched the track, and thier were four of them.

TED Challenge

We visited the TED sight and explored if for a while to see what was going on and do a project on it.
                                                      http://www.ted.com/

1) What is the TED organization about?
The TED organization is about spreading good ideas and knowledge to anyone.

2) What is the purpose of their website and how does the functionality of their site support that?

The TED website is the vehicle that they use to spread their videos on a huge scale. Their sight supports that by allowing people free access to thousands of videos on a wide range of subjects.

3) As Engineers and Problem Solvers, which topic areas (the choices from the "Show talks related to:" section on the sidebar) are of most interest to us? Justify your answer.

The topic titled technology would be the most interesting to us because when the technology changes or becomes more advanced or a new thing comes out it could dramatically change the way we engineer. For example if a new way to make structures stable came out and it turned out that circles were much more stable than triangles then whenever you were making say the role cage for a car it would be based on circles rather than triangles or anything else.

4) Based on your previous answer, what are 3 talks (videos) on the site that appear like they would be of most interest to you as an Engineer/Problem Solver? Justify your choices.
Vijay Kumar: Robots that fly ... and cooperate     http://www.ted.com/talks/vijay_kumar_robots_that_fly_and_cooperate.html
Blaise Aguera y Arcas demos Photosynth
http://www.ted.com/talks/blaise_aguera_y_arcas_demos_photosynth.html
Dennis Hong: My seven species of robot
http://www.ted.com/talks/dennis_hong_my_seven_species_of_robot.html

5) Each student will watch a unique video (clear your choice with me... first come, first served!). Watch the video. Embed the video in your blog post and create a bulletized outline of the key issues presented in the talk.


-The smaller the device is the more agile it will be in the end
-With different sensors the devise will be able to calculate and plann its own path
-There are lots of different aplications that can be used with these devises like building carying things and exploring an unknown area remotly
-With more reserch and desigh they can become a verry usfull tool in our wourld.
6) How could you get involved in the field/technology/issue you chose to hear about? What experience/skills/training/education would you need to learn to get involved with this field?

I could go to school and learn about roboticks and physiscs and then continue on to collage and enter the program that is conducting theis reserch and try to help out with it.

Egg Drop Challenge

We started with one original designe then we compleatly morfed it into a combination of two designes, #3 and #6 (the 6 one was changed also in it's way we droped it).
These where aour first three designes that we came up with
1. Was suposed to be two spunges around an egg with wings on eather side of it so that it could flowt down and hit the ground softly.
2. Is the idea that we would just drop a egg with a parachute and a cone on the bottome of it and also a bucket at the bottem on the ground so that the egg would go down and hit the watter so that it would slow it down and stop at the bottem.
3. Was suposed to be an egg with several sheets of cardboard around it so that when you droped you would spin it so that the cardboard would create lift and slow it down.

4. Is an idea that we had to make a tube of paper with flaps down the inside and the egg sitting on the top so that you would drop the hole toob and inside the tube wile it was falling the egg would fall down the tube and be slowed down by the flaps and then it woul end up falling into a bucket of watter.
5. This was an idea that we had to make a long tube out of paper or ductape and so that the bottem was smaller than the top so that when you droped the egg down the top it would end up slowing down the hole way and end up stopping right aboce the ground.


6. This was the idea that we chose and it was to make a long role of paper with the egg at the center so that you would role it of the side of the balconey and it would be slowed by tape and it would just stop right above the ground.

This was our decision matrix

This is our list of items to bring and also our plan for making shure we brot them all in.
Suplies - 15-20 peices of paper and ductape
Plan- write them down in our agendas
This is our plan in action

Paradigm Shift

I watched the video on Inscribed and Central Angles in Geometry and it goes right with what I am learning in class. It was very informational and an exelent way to maby make up a lesson that someone had missed.
http://www.khanacademy.org/math/geometry-1/core-geometry/v/inscribed-and-central-angles

The video was great in almost all aspects of it but if i had to change somethings I would sugjest changing the variables that he used to more common ones and some of the collors were hard to see but every thing else was greate.

"Sustain"
The video was very thuro in how he explained the topic, he did not just tell you about the toppic he walked you through three different proufs of the topick.

"Change"
I kind of dont agree with flipping the classroom in several classes but I can see how it would work in other ones. For example I dont think it would work very well in history but it would work in math.

2.1.6 Model Creations



















Why is it imprtant to be detailed when documeting your desgn?
Because you may forget what exactly you did to get the resolts that you got.

How is an object's mass different from its weight?
The mass is the total space and the wight depends on what material the object is made out of.

How does surface area differ from area?
Surface area is the total area and area is of just one surface.

MoneyBall Response

1) What was the “Moneyball” approach that Billy Beane and Peter Brandt applied to the Oakland Athletics 2002 season? Was it an “art” or a “science”? What single statistic did they boil their value consideration down to?

They went by the statisticks not by what the scouts thought about the players. It was much more of a science rather than an art because of how they went around finding out who they would have taken up rather than who they felt in their gut. The single most important statistic that they used as their core value was that they got on base rather than a conjoined of several lower things or how they looked.

2) What is the equation used to calculate OBP?

OBP-On-Base Percentages=             Hits +Walks +Hit By a Pitch
                                             ___________________________________
                                             At Bats +Walks +Hit By a Pitch +Sacrifice Flies

3) What is design?

Design is the prose’s of defining the problem to finding possible solutions to getting a solution and the two revising the solution, and starting it all over again.

4) Describe 3 situations where movie characters (intentionally or not) applied a step from the PLTW 12 Step Design Process. Explain both the (a) situation as well as (b) how the step is relevant:

1 -In the beginning where Billy is with all the scouts and they are think of who to hire to make up for the people they lost and Billy makes them think of what the real problem is.

2 - Peter's whole reason that he has to hire some people and fire others is that he has a long equation that gives him the averages of the player. And that lets him help the players even more.

3 - And through the whole move Billy is revising his team and making it better and making shure that his coach plays the team how he wants them to be coached.


5) What is “Leadership”? List the three aspects of leadership that we come up with in class.

1 - Direction
2 -Alignment
3 - Vision


6) Describe 3 circumstances from the story where a character exercised effective leadership:
1 - Through the movie Billy always has a direction he wants his team to go in and it is always a good one and its consistent.

2 - Billy always on track and never straying from what he has to do for his team.

3 -Billy consistently is trying to do what is best for his team even though he is staring in the face of great challenge.



7) According to the movie, what was the A’s record at the start of their winning streak? 68:51
8) What does this ratio simplify to? 1.33: 1

9) How long was the A’s record setting winning streak? 20 games won.

10) Given the A’s win/loss ratio at the start of the streak, what are the odds of winning 20 games in a row? Run the numbers.
The odds were about 0.000013 chances that they would win the 20 games. And it would take about 474 seasons to achieve this 20 game winning streak,

11) Based on your calculation, do you think the A’s got lucky or was there something to the Moneyball approach?

I think that they had a bit of luck with some of the Moneyball approach filling in the rest of the reason that they won.

12) Did Billy Beane strictly apply the “science” of Moneyball to his management approach? Was there an “art” to his efforts as well? Describe a circumstance where he broke from the Moneyball approach to make a positive change for the team.

Billy Bean did not go completely Moneyball but was greatly influence by it and it was partly his art that helped him to make other decisions. The only time that he strayed from his plan was when he had to triad some people to twist they had of the coach so that he would play the team how Billy wanted him to.



Bonus Question
Money Ball was originally a book. What author wrote the book? What other books has this author written? Is there a theme to his writing?
Michael Lewis wrote the book along with The Blind Side: Evolution of a Game, Coach: Lessons on the Game of Life, and Liar's Poker. All of these have a common theme of the little guy coming up and winning it all.

1.    What 3-D CAD functions could be used to create a wire coat hanger?
 The Sweep function would be the best to use to make a wire coat hanger.

2.    What feature would be used to create a 3-D representation of a spindle that was created on a wood lathe?
 The Revolve tool would be best to use to make a spindle.

3.    How does a 3-D CAD solid model program keep track of the changes that are made to an object?
 On the left side thier is a list of what is changed or modified.

4.    If a mistake is made, how does the user make a correction without using the undo function?
They could do the opposit of what they did in the first place or deleate the item frome the bar on the left.
