2. Goals & Outcomes
Appreciating science in general, and astronomy in specific.
Developing a working knowledge of the scientific method and how to apply it to real world situations.
Critically analyzing and evaluating information, scientific or otherwise
Diagram the positions of the Sun, the Earth, and the Moon during solar and lunar eclipses.

FOCUS OF THIS LESSON:
Telling time & direction from the appearance of the Moon.

???Go outside with golf ball and see phase of golfball today???
If not today, try this on your own with your own white sphere.

Given a picture of the Moon, name of phase or eclipse, complete all of the following:
Draw picture and name each phase
How much of the Moon is lit, and how much of the lit part we see? Why is the dark part not lit?
If facing the Moon at any phase, which way (right/left/behind) do you turn to face the Sun? Name direction (NSEW)
Approximate time, based on the Moon’s phase and location in the sky

20. Clicker questions coming
My advice:
Take out some notebook paper.
I will fill in the blanks on the board. Copy info down.
Write your guess someplace off to the side so you can cover up your answer when you study your notes
Write the correct answer in another place you can cover up, NOT immediately next to your first guess.
This will make it hard for you to peek at the right answer when studying your notes
