2nd Annual Egg Drop Challenge!

We will conduct the 2nd Annual Engineering Egg Drop Challenge next week!

Your goal is to design and implement a solution for our client that allows us to drop an egg from our class balcony onto the concrete below without it breaking.



The PLTW 12 Step Iterative Design Process (click to enlarge):




Our agenda for Egg Drop Week (next week) supports an iterative design process:

Monday is "Prep Day"
Team up with a partner
Define the challenge, criteria and constraints.
Brainstorm solutions.
Identify materials to bring in for "Build Day" (block day)

You must bring in the materials you want to use for Block Day!


Block Day is "Build Day"
Use the materials you've brought in to realize the vision of your design.
Crash test dummy eggs will be provided.
You may test your design off the balcony


Thursday is "Test Day"
Click here to see correct drop technique.


Friday is "Iteration Day"
Redesign as necessary.
Reimplement your design.
Capture your experience in your portfolio.


Score
An Achievement System will be used to score your effort on this activity.
The number one priority in this effort is to not make a permanent mess (no Jello, materials that will stain, etc. If you have any question about materials, please see Mr. Olson).
Our next priority is to have a great time solving this challenge! :)
Please note that all materials used in your solution must be "delivered" from the launch location (you may not place additional material on the target from the ground for instance).

Whole Eggs

Egg Drop Challenge: Iteration #1 Blog Post Write Up

(a list of team weights from our first annual Egg Drop Challenge. 5th period on the left, then 3rd and 4th period on the right. Click to enlarge.)


Below are instructions to help you structure your Egg Drop Challenge write up. Your write up will be scored for your grade on the activity.


1) Title your post "Egg Drop Challenge - Iteration #1"


2) At the top of your post list the following:
"Total # of Achievements Earned: X"
(where X is the number you earned)


3) Post an image of your Egg Drop solution.


4) Justify (list and explain) your Achievemtns. Use images as appropriate. For organization's sake, use the categories provided in the Egg Drop Achievement List.


5) What designs from your class did well? Based on the achievements you earned, how would you redesign your solution to score better? Be specific (sketches with labeling work well for this).

Engineering Egg Drop: Achievements!

Your team will earn "Achievements" for your efforts on the Engineering Egg Drop. Your final grade for the effort will be based on how your Achievement score stacks up (curves) against the Achievement score of the other teams in your class.

The more achievements you earn, the better you'll do!


***All Achievements must be documented in a single Engineering Egg Drop Challenge post on your online portfolio (blog)... use photos/images to justify each achievement!***


The following is a list of achievements available to earn (clever achievement names to follow):



Idea Generation Achievements

Brainstorming
-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.

Material Prep
-Generate a list of materials required for build day.
-Document a plan to ensure materials are brought in on block day.
