Great Diagrams for Astronomy

http://www.mhhe.com/physsci/astronomy/arny/instructor/indexnew.mhtml

This week we'll be adding to our planet booklets and doing an in class project, comparing the planets' size and diameter and finding a ratio that enables the students to fit the planets on the paper to scale.

Our goal is to finish astronomy this week-at least the high points- and spend the rest of the time after spring break reviewing for CRCT using a competitive game format!
