Objective: SWBAT identify why the moon appears differently throughout the month and how the position of the moon around the view from Earth by modeling Earth, Moon, Sun systems
Do Now:
Question 1
1.
Shade in the Earth and Moon from the Top-View below.
Question 2
2.
Why do you think the Moon might appear half illuminated even when the moon is behind the Earth in a top view?

Guided Notes:
Question 3
3.
Why do you think the appearance of the Moon and the stone sphere is similar in this way? (Hint: Think about the light in the image.)
Question 4
4.
Model the Earth, Moon, Sun system below.
Practice:
Investigation Question: If half of the Moon is always illuminated, why does its appearance from Earth change?
Claim 1: The Moon’s appearance changes because Earth casts a shadow on the Moon.
Claim 2: The Moon’s appearance changes because the position of the Moon changes.

Question 5
5.
View from Earth Modeling:
Use the simulation to model the moon from the Top-View, and View from Earth at each of the locations below.
Do:
Complete the Top-View moon diagram indicating how much of the moon is illuminated
Draw Earth View perspective lines from a single point on Earth to each side of the closest Moon
Draw the correct Moon Phase (view from Earth) for each of the Moon Phases below
Question 6
6.
How does the position of the Moon in relation to the Sun and Earth impact when the moon is darkest from the View from Earth? Lightest?
Exit Ticket:
Question 7
7.
Draw the correct Moon phase (view from Earth) to the location at each of the places around the Earth.
Question 8
8.
Explain why the moon appears different in each position from Earth? What patterns can you observe to predict the next moon phase?
(think: How does ithe moons position impact how much light we see?)
