My bow

I made this bow out of straws coffestirs, twine and labels it fuctions quite well considering the materials and it shoots bolsa wood arrows but the speed it shoots them at is too fast for the arrow because it does not have fins to stableize during flight

Planes!

1) Provide a breif description of the activity. Who did you work with? What did you build? What challenges did you overcome to succesfully craft your aircraft? This project was to see who could make the best plane we started from the materials given and used the diagram to assemble it, I worked with Timmy and Justin and we over came the prop mount from scooting back and making the prop hit the frame by recessing it into the frame. we took out the wing mount because it was a weak point and did a direct mount wich was simple and affective and it did alright we could have don alot better but was a decent build!

2) Post a photo of your glider under construction.

3) Post a photo of your finished design.

4) Describe how you tested your aircraft and tuned its flight characteristics.

we didnt have much time for testing seeing that we finished our aircraft the same day of our competition but we threw it from the second story to see how it flew and made corrections for balance using tape.

5) Describe how well your aircraft flew in our competition. Did you win any events (furthest distance, longest time aloft)? Were you competative in our best decorated flier competition? we had the furthest distance the first throw and then everything went down hill from there sadly haha.

6) Pick three steps from the PLTW 12 step design process and describe how your team worked through these during the course of this experience. we brained stormed,modeled and prototyped, and tested and evaluated.

1 DOLLAR EVERY SECOND EVERYDAY

If you spent 1 dollar every second of every day in 12 days you would've spent $1,000,000 in 32 years you would've spent 1,000,000,000, in 31,688 years you would've spent $1,000,000,000,000. OUR NATIONAL DEBT IS $15,000,000,000,000!!!!!!

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? (In class research/discussion) It  was to find players that didnt cost very much but had a high OBP, it was most definately a mixture of both it was sciences that found out the stats but an art to make the best chemistry for the team. and it was OBP.



2) What is the equation used to calculate OBP? (In class research/discussion)

3) What is design? (In class research/discussion)
Decide upon the look and functioning of an object.
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 -When the scouts were disccusing who to trade and/or cut.

2 - He figured out his process when he foundout his budget was low

3 - When Billy went away from the moneyball ideal when he traded Giombi and Pena


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

1 - direction
2 -organization
3-leadership


6) Describe 3 circumstances from the story where a character exercised effective leadership:
1 - Billy made scouts identify the problem before trying to solve it.


2 - Billy fired the head scout for the good of the team and management.

3 - Traded Giambi even though he was part of the money ball pick.



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 (roughly)?.57: 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 (listed two questions above), what are the odds of winning 20 games in a row? Run the numbers. (In class research/discussion) .0000013


11) Based on your calculation, do you think the A’s got lucky or was there something to the Moneyball approach? I think luck had something to do with it but definately think the moneyball technique worked in this situation.


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. He used his intuition and traded Giambi even though he was a money ball pick he was not good for team morale







Bonus Question (look into this if you’ve finished ahead of the class):
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?
