EGG DROP CHALLENGE! Iteration 1

Total # of Achievements Earned: 19
-Create a sketch of one possible solution. Include labels.
-Create a sketch of another possible solution. Include labels.
-Create a sketch of a third possible solution. Include labels.





                                           -Use a decision matrix to justify the approach you chose.



























Material Prep
-Generate a list of materials required for build day.
-Document a plan to ensure materials are brought in on block day.  ( I brought in cotton balls, ziploc bags.  Nick brought baloons and tape)


Build Achievements

Material Size:
-Your materials fit inside a printer paper box
-Your materials fit inside a shoe box (WOULD FIT IN SHOE BOX)

                                                        Material Weight:
-Your materials weigh less than 500 grams.
-Your materials weigh less than 300 grams.
-Your materials weigh less than 200 grams.
-Your materials weigh less than 150 grams. (OURS WEIGHED 115 g)


Drop Achievements

Drop Accuracy:
-You hit the butcher paper!
-You hit inside the third ring!  (OURS HIT THIRD RING)

Egg Resilience:-Your egg broke but the yolk remained intact.
-Your egg cracked but the yolk stayed inside and intact. (OUR EGG CRACKED BUT YOLK STAYED INSIDE)
Calculation Achievements
-Describe an aspect of the event using arithmetic.    
  •  Our bag without the egg weighed 115 g and the egg itself weighed 55g. So, 115 + 55 = 170 g for the bag and egg.
-Design an Achievement Mr. Olson approves for next year's Egg Drop Challenge.
  • THE ULTIMATE CHALLENGE- If the egg drops and survives the first round, drop it from a higher level like from the roof. If survives again, awarded twice the amount of points!!
-Redesign:
  • The target was pretty hard for people to hit, so I think by making more rings it would make it easier to hit.

University

I have thought of going to Universtiy of Colorado at Boulder for some time now. And Aerospace engineering really interests me.  Below are the required courses to graduate with a degree in Aerospace Engineering.
  • Calculus 1,2,3 for Engineers
  • Engr. General Chemistry & Chemistry Lab
  • Engineering Projects/ASEN 2500 Gateway to
    Space
  • Computing Requirement
  • Intro to Statics, Structures & Materials
  • Intro to Thermodynamics & Aerodynamics
  • Diff Eq with Linear Algebra
  • Intro to Dynamics & Systems
  • Aerodynamics
  • Structures
  • Thermo & Heat Transfer
  • Physics
  • Aircraft Dynamics
  • Orbit Mech./ Att design & control
  • Electronics & Communications
  • Aerospace Materials
  • Foundations of Propulsion
Of the above classes, based on class description, the GATEWAY TO SPACE class sounds most appealing. It covers  basics of atmosphere and space sciences, space exploration, spacecraft design, rocketry, and orbits. The whole idea of the existence beyond earth fascinates me, so I think I would really like that class.

In addition, an elective is required each semester, totaling in 8 electives.
Electives come from the following fields:
  • Contempory Societies
  • Human Diversity
  • Foreign Language
  • Historical Context
  • Ideals & Values
  • Literature & Arts
  • United States Context

TED

1. What is TED organization about?
----The TED program is devoted to Ideas Worth Spreading, and wants to bring technology, entertainment, and design together. Its web site has tons of videos about new and bright ideas.

2. What is the purpose of their website and how does the functionality of their site support that?
----The purpose of the site is to spread ideas that are revolutionary and inetesting. The website is comprised of tons of videos of prefessional's talks about these ideas.


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.
----I would say that "Technology" and "Design" categories are most relevant to our class. Engineering is all about reinventing designs and making them better, and technology can be a way to do that.

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.
  • "Breakthrough Designs for ultra low-cost products" is one because part of engineering is making products cheaper and easier to produce.
  • "Using Natue in architecture" is intersesting because some animals and plants have such great desings that allow them to survive, and if some of those designs could be put to architecture it could make buildings much stronger and efficeient.
  • "Haiti's engineering disaster" is also interesting because the earthquake, although it was bad, wouldn't have caused as uch damage if Hait's buildings would have been better built.




Michael Pawlyn says some really interesting things in his video.
  • he says that in nature lots of things are in closed loops. We should intergrate this into our lives               ------ For Example, we should have restraunts with their own ponds, greenhouses, and and waste centers. The greenhouses create plants which can be used for food, ponds which are stocked with fish and fed worms from greenhouse. And waste centers that get rid of trash and create electricity while doing so.
  • We need to switch from fossil fuels to solar. The sun gives us 10,000X the energy than we create from all forms. Thats a lot of potential energy that can be harvested.
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?
----It might be hard to get involved with these things at my age, but I'd like later on. Maybe some knowledge in environmental sciences would help me with this. And this is a huge field right now as we are starting to switch to a "green" society.
