Wing Model Task
Wing Model
Federal investigators found a wing at this exact spot on the crash site. The FBI took
the wing but left a scale model for us to look at. The weight of the uranium in pounds,
a three-digit number, is the code to access this piece of evidence.
Chemist
Locate the purple triangle on
the ground. This is the scale
model of the spaceship wing.
You can see the markings
where someone measured
it using a safety pin.
The safety pin was 3/2
(or 1. 5) inches long.
Cryptologist
As a team, figure out the
measurements of the side
lengths of the wing.
When you are done, write
your answer on the paper
you were given.
The largest of the three
measurements is the code
to access your next piece
of evidence.
Computer Hacker
We hacked into a government
computer and found this:
Data on Military Spacecraft
* Top Secret
According to CIA data, in a
military spacecraft, the ratio
of longest side to shortest
side has to make a fraction
that reduces to 5/3.
In other words, if you have a
military craft:
Longest side 5
Shortest Side 3
Write this proportion down
for later.
