"Egg Drop Challenge - Iteration #1"

We used a trash bag as a parachute and put the egg in the cup surrounded by cotton balls

"Total # of Achievements Earned": 22

- Our first achievements came from our supplies could fit in a cigar box if we crushed the cup, that's 3 ach.
- Our idea weighed less than 50 grams so we got an extra 6 achievements.
- Our first attempt hit the paper so we got 1 achievement.
- Our egg did not crack at all so there is 6 more.
- We used algebra to find the distance the egg falls, geometry using shapes and arithmetic to add the distance of the fall, we got 3 for this.
- Our last four achievements came from brainstorming and generating ideas.



- Our designs did pretty good but Mike's paper parachute did well and Connor's egg didn't break also.
- We could make our idea better by maybe dropping off a higher height so the air would have more time to catch. We could also improve it by having a helium filled balloon tied on top for even more air.

TED pt I - Ideas worth Spreading?



1) What is the TED organization about?
   - TED is about people talking about all the things happening in the world and theories about some of the problems the world has today

2) What is the purpose of their website and how does the functionality of their site support that?
   - The purpose of their website is to talk about new science breakthroughs or problems or events that are currently happening. Their site supports it by getting different speakers for different topics and know what they are doing

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.
   - Technology is important to us because the whole world is technology now and we need to build something to support it. Design is also important because as engineers we need a design to have to build off of and expand on.

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.
   1. Thomas Thwaites: How I built a toaster -- from scratch
   2. Reviving New York's rivers -- with oysters!
   3. Cynthia Breazeal: The rise of personal robots

5) Each student will watch a unique video. Claim your video on the following period specific posts: 2nd, 3rd, 4th, 5th. If no one else has claimed your video, leave a comment on that post to call the one you want. If someone else has already claimed the talk, go back and pick another one. Watch the video. Embed the video in your blog post and create a bulletized outline of the key issues presented in the talk.
   - Some key issues in the video were money cost, transportation, and the knowledge to build the machines and robots for the military. It will cost a lot of money to built these advanced technologically robots because the builders and designers come from all over the world, and you need the knowledge to know how to build these robots. They suggested military students to study the technology behind the robots.

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 get involved by getting acquainted with the military technology and design a couple of layouts of some new ideas, but I would have to specialize into that major in college or something.

Reverse Engineering: Mechanicnal Product - Functional Analysis

1. What is the purpose or primary function of the object?
   - The purpose of the clock is to tell the time of day or night

2. Make an educated guess as to how this product operates. Use simple machines’ terminology to explain the object’s sequential operation.
   - I think the clock as continuous spinning gears rolling off each other constantly making the clock move, moving the wheel in the back to change time makes it go faster for a different time

3. Identify the system inputs, intended product function, and outputs. Use power point to create a "black box" graphic like the toothbrush example discussed in class. Save the slide as a .jpg image and post it to answer this question.

4. What mechanical components are visible?
   - mechanical components that are visible are the second hand with the hour and minute hand constantly moving with the time of day, the axle moving the hands are visible with the knob in the back

5. What is it about this device’s function that you cannot identify, because the mechanical components are hidden from plain view?
   - You cant identify how it moves and how fast it moves because all of those components are in the back of the clock, the mechanics that back that keep the axle moving
