3.
One of the galaxies should have been labeled "R". What was the purpose of this galaxy?
a)
It was the Red galaxy
b)
It was the Reference galaxy
c)
It was the galaxy that was receeding
d)

4.
How did you calculate the distance traveled by the galaxy?
a)
Measured the distance between the galaxy and the reference point after the balloon was fully expanded
b)
Measured the distance between the galaxy and the reference point when the balloon was 1/4 the way full.
c)
Measured the distance between the galaxy and the reference point twice. Once when it was 1/4 full and again fully expanded. Then took the difference between the two
d)
Measured the distance between the galaxy and the reference point twice. Once when it was 1/4 full and again fully expanded.
5.
How did you measure the Velocity the galaxies were travelling?
a)
Divide the original distance between the galaxy and the reference point by the time it takes to fully expand the balloon.
b)
Divide the final distance (fully expanded balloon) between the galaxies and the reference point by the time it took to blow up the balloon
c)
Divide the difference in the distance traveled by the time it took to fully blow up the balloon
d)
Multiply the difference in the distance traveled by the time it took to fully blow up the balloon
