Picture of Completed Work Sheet

Activity 3.1.2 Flowcharts: Designed flowcharts for various operations

Completed Flowcharts from Activity Sheet

Activity 3.1.3 Basic Programming: Learned functions of robopro and how to make a flowchart that controls the actions of the motor

Here were the Conclusion questions for this program :

Activity 3.1.4 Branch Functions:Used new flowchart object in order to allow computer to make decisions using criteria based on empirical data.

Activity 3.1.5 Variable Functions:  Created a program that controls the number of times a light turns on and off using variable program blocks.

Conclusion:

1.    Describe how you might modify the Plus command so that it can reset a variable block to 0 within a program.

Change the plus to a minus.In order to keep track of data
 2.What might an industrial or manufacturing engineering need to count or keep track of? Describe one example.

It would be necessary to keep track of how many operations or tasks have been completed.

Activity 3.1.6 Open Closed Loop Systems:

For this activity we created a train type system in which the motor moved forward and backward on a track.

activity 2.1.7

Here is my completed work for Activity 2.1.7 : Calculating Truss Forces. During class we have been learning about how to build stable bridges as a lead up to our final Design and Bridge Building Challenge. I will be posting about the challenge soon.

bridge building

We just finished the wrap up to the bridge building lessons that we have been completing over the past few weeks. After learning how to calculate truss forces and moments we were able to create a stronger bridge. To test strength of the bridges, magazines were placed on the bridge until the bridge collapsed. My team's design was one truss( since we could only use 3 folders making a true bridge with double truss and a connector would go over the folder limit. The triangle design held but gave in on the asymmetrical side by the 12 magazine. At least it was better than the first time around.

Here is a video of one of our first tests

Here is a video of the final test

     Over the past month, I have been in need of a new gaming PC, so I started doing work for my dad and in about three months I came up with just enough money for all the parts I need. It took me a while to assemble a list of all the best components in my price range, but once I did, I assembled it and started playing. The assembly was quite the adventure for me because I had absolutely no background knowledge in the process, but once I it started it all made sense from there.

our marble sorter for principles of engineering

    In the past few week of my engineering class,my group (Isaiah, Ian, Shana) and I, have been working and testing ways to sort at least three different kinds of marbles. We constructed a device using fisher tech equipment and some other materials to separate wood, metal, and glass marbles. To separate the wood and metal from the glass we found that the glass were slightly bigger that the wood and metal, so we made a section of the track small enough for the glass ones to role on but big enough for the wood and metal ones to fall through. To separate the wood marbles form the metal ones, we used fans to blow the wood ones out of the way but not the metal ones, because the wood ones were significantly lighter than the metal ones.  Another aspect of the challenge was to make a funnel to set the marbles in to the sorter, for this we made a cone-like structure out of styro-paper and cardboard. When we were ready for our final test we came across some complications, first was the funnel, when we dropped the marbles they would jam at the exit of the funnel. Another complication that we came across was that when it came time for the wood to be separated from the metal, the marbles would be going too fast and wouldn't be affected by the fan. With a few modifications,  we were on our way to a semi functional marble sorter.

Egg Drop Challenge

     This was my first egg drop challenge for me, my design was a bunch of sandwich bags inflated and taped together surrounding the egg. For most of this project I worked alone, until the final drop day, when Johnny came. My contraption, or pod, was completely deflated, so him and I reinforced it with a couple of more baggs. When we dropped the egg suvived landing in the bullseye. The seond time it dropped the egg cracked and it landed right outside of the bullseye. I feel that we got no acheivements because ours was definately not the smallest or the lightest, and ours fell pretty fast. i am looking foward to the third anual egg drop challenge.

Provide "sustain" (positive) and "change" feedback regarding your experience with using the video to supplement your learning.
I used this video to help me with my math because i have a test on this subject in two days, it helped me remember some of the stuff we learned in classs.
"Sustain" - what works well for you with the video you chose? 
The way he explained it worked well for me
"Change" - Is there anything you would change regarding the video or the concept of "flipping the classroom".
I would have put more examples of different kinds of problems on the video
In your opinion, could "flipping the classroom" work out? Should education institutions work towards this new paradigm?
I dont think it could work out because you cant ask the video any questions.

balsa wood plane

1.the idea of this project was to create a plane out of balsa wood, glue, and tissue paper (other materials were provided)
 
this is my plane under construction-


.














     I tested my plane for the first time and found out that it was a little back heavy, so  added some more balsa wood in the front of the plane, I addid it in a way were it look  a cool unique disign, after this happened my plane ended up flying the longest in the class. I also was the first in the class to finish my plane.

money ball questions

Use internet research and class discussion to answer the following questions.


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 get players that get on base most for a low bugget


3) What is design? (In class research/discussion)

the inovations of a product for more benificial purposes or the creation of a tool that will solve unsolved problems

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 money ball when billy is telling his associates to identify the problem with the team


2 - when billy was eliminating giambi from his team, he was removing a flaw in his team


3 - he avioded a problem by not gooing to the games to jinx  the game



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

1 - allignment
2 - direction
3 - comitment


6) Describe 3 circumstances from the story where a character exercised effective leadership:

1 - in money ball when billy is telling his associates to identify the problem with the team


2 - when billy was eliminating giambi from his team, he was removing a flaw in his team


3 - he took initiative and took a lot of these random players and improoved his team


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)? 76923__ : 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)

there is 76932 to 1 chanse that they will win 20 games in a row

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

i thought it was pure luck
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.

i think that it was strictly science because he didn't care about the look or reputation of the players, he just cared about there stats and skill at the game
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?

Michael Lewis wrote the book, he also wrote The Blind Side. he seems to like sports and emotional suspence in his novels, he also writes about true stories.
