Egg Drop Challenge

Total achievements earned: 25


Our design was two air packs surrounding the egg held together with tape. We slowed this down sigtnificantly with a parachute. A suggested achievement for next year would be length of flight time, awarded in steps like size and weight.






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.



-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.




Build Achievements

Material Size:
(your egg is not included in the material size)
(air is ubiquitous and not included in material size. "Rare" commodities like helium are.)
-Your materials fit inside a printer paper box
-Your materials fit inside a shoe box

Material Weight:
(your egg is not included in 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.
-Your materials weigh less than 100 grams.
-Your materials weigh less than 50 grams.


Drop Achievements

Drop Accuracy:
-You hit the butcher paper!
-You hit inside the third ring!
-You hit inside the second ring!

Egg Resilience:
-Your egg didn't break in any way! (awarded three times)
-Your egg didn't break in any way! (awarded three times)
-Your egg didn't break in any way! (awarded three times)


Calculation Achievements
-Describe an aspect of the event using arithmetic.
-Describe an aspect of the event using geometry.
-Describe an aspect of the event using algebra.
-Describe an aspect of the event using calculus.


In our class, our design did quite well, as well as Mia's design, which was much like our brainstorm #3.

Next time, I would try to make our design more accurate to hopefully get a bullseye. Maybe we could add adjustable wings to guide it depending on the wind.

Glider Challenge

Because I was absent for a majority of the assignment, I did not make a design myself. Instead, I took pictures of the day the gliders that were tested. Below, in Rafe's left hand is the winning design. It was a very simple paper airplane, yet it went the furthest.





Below is a full shot of everyone about to throw their gliders. It was a problem to throw them here because a draft was created by the walkway you can see below the poster.


Here is Henry's design. It did not work quite as well as Rafe's because the wings were so long that they weighed it down which made for poor long distance flight time.
