NASA Connect segment that challenges students to participate in an activity to scale the universe. The video involves students in a proposal to determine a new baseline distance to use for an astronomical unit.
They say you learn something new every day, and I sure did.

I'd never heard of transits before, and how astronomers and scientists use them to
00:00:06
determine the astronomical unit.
00:00:11
Thanks, Janet.
00:00:13
Okay, guys, remember earlier in the program when I said I had an interesting challenge
00:00:14
for you?
00:00:18
Well, it's now time for scaling the solar system.
00:00:19
Now, the astronomical unit, or AU, currently in use is derived from the average mean distance
00:00:23
between the Earth and the Sun, which is approximately 93 million miles.
00:00:29
Working in groups, your task is to make a proposal that uses the average mean distance
00:00:33
between the Sun and another planet in our solar system as the basis for determining
00:00:40
the astronomical unit.
00:00:45
In other words, is there a better baseline distance to use rather than the Sun-Earth
00:00:47
baseline?
00:00:52
What about using a Sun-Jupiter baseline or a Sun-Pluto baseline?
00:00:53
Once you choose another planet, you will have to recalculate the scale of the solar system
00:00:59
using your new chosen baseline, and then explain why your new baseline is a better choice than
00:01:04
the Sun-Earth baseline.
00:01:10
What are the advantages and disadvantages to your new scale?
00:01:11
Detailed instructions and tips on how to make your proposal can be located at the NASA Connect
00:01:16
website.
00:01:22
From the website, we encourage you to submit your proposal.
00:01:23
Your proposal will be seen by millions of students across the country.
00:01:26
We look forward to your submittals.
