THS Earth/Space Science

How do we go about discussing the size of the universe?  Today we began this discussion by defining some terms we’ll need for the rest of this unit:  Solar System, Galaxy, and Universe.  Tomorrow we’ll continue on this track with the viewing and discussion of the well-known Eames film “Powers of 10″.

We also took a quick open-note quiz on the History of Astronomy presentations and interpreting Sky Maps.  Make sure you bring your sky map home with you so you can continue becoming familiar with the night sky.  The skies will be cloudy for the next couple of nights, but later in the weekend into next week should bring some dry, clear skies – perfect for star gazing!
