Go to Campus Observatory!

If you haven't already been to Campus Observatory, go ASAP. There are only 4 sessions left. If you miss, there is no make up AND you cannot drop either of the Campus Observatory grades (even if you get a zero for them)!

Lab #4: Comets & Asteroids

Tip:

~We'll be using flour, ammonia, and dirt in today's lab... you should avoid wearing black or really nice clothes... if at all possible.
