Dr Brad Tucker: The Sun, Earth, and Moon

We will talk about how the Earth, Sun, and Moon all work together. We'll touch on day/night, seasons, and the phases of the Moon. We'll do a demo of the phases and seasons that you can do at home, not only for the Moon but other planets! We'll also talk about viewing the phases of the Moon and Venus this month.
