 Know what direction the Earth rotates.  Know what direction the Earth revolves.  Know the differences and similarities
between rotation and revolution.  Be able to explain how day/night happens, and  draw a diagram showing how day/night
happens.  Be able to explain the relationship between what happens during Earth’s orbit that causes seasons, and  draw a
diagram to support your explanation.  Be able to explain what beam spreading and solar angle have to do with seasons.  Be
able to explain why certain geographic locations are always colder in general and others warmer.  Be able to explain why day
length (amount of daylight) varies from latitude to latitude.  Be able to draw Earth/Sun system diagrams from side-views
and North-Polar views, showing accurate revolutions and axes, when necessary.  Know what defines a day and a year. 
