Phases of the Moon
Watching the moon change phases gives us a good sense of time passing on a daily basis. See if you can predict the time it takes for the moon to pass through all of its phases.
Create a calendar-like page and see how many times you can record the phase of the moon. Be sure to also record the time of day and position in the sky that you observed the moon. Do this for at least 2 weeks.
Based on your observations, how long do you think it takes the moon to pass through all four phases? For example: How many days between full moons or new moons?
