Solar System distances, math practice, quiz tomorrow.

HMWK:  Study for quiz tomorrow - chapter review pages on 212-215 should be a pretty good review of most of the concepts we've learned so far, and you will also have a math problem relating gravity and astronomy or distance/speed  and astronomy.  

Today: discovery of the asteroid belt and Neptune, mean distances from the Sun, in A.U. are:

0.39, 0.72, 1.0 (Earth), 1.5, 2.8 (asteroid belt), 5.2, 9.5, 19.2, 30, and just for Raven and Paige in 4th hour, 40. = pluto  (these are slightly more exact than the original predictions were)

I will give you these values to use on your tests; you need only know how to use them.

Asteroid belt was predicted by a numerical sequence, Neptune was found due to its gravitational disturbance on Uranus.

The practice problem(s) we worked today working with speed, distance, and time AND these astronomical units should be pretty relevant for your quiz; you will have either something dealing with speed and distance in the BIG scale of our solar system or you will have a question dealing with gravity.
