Objective: SWBAT identify and describe the changes in the appearance of the Moon based on rotational positions of the Earth, Moon, and Sun
ESS1-1: Develop and use a model of the Earth-sun-moon system to describe the cyclic patterns of lunar phases, eclipses of the sun and moon, and seasons.

Question 2
2.
Launch the Earth, Moon, and Sun Simulation. In Top View, move the Moon to each of the positions shown below. Then, observe the Moon in View from Earth.
Record your observations by labeling each of the Top View images below. How much of the illuminated part of the Moon is visible from Earth?

Question 3
3.
Goal:
With a partner, use the Sim to investigate the phases of Earth that astronauts see from the Moon.
Do:
Use both Top View and View from Earth to answer the questions below.
Have one partner use the Sim while the other partner records the answer to each question. Be sure to talk about what you see in the Sim before you record your answers. Switch roles each time you answer a question.
How much of the moon appears illuminated from the top view? Does this ever change?
CFS:
Accurately identifies the position of the Moon to predict the correct Moon phase
Accurately describes the relationship between light and the appearance of illuminated objects
Accurately describes the relationship between the moons position and the appearance

Question 5
5.
Felipe believes that whenever the Moon is in the position that is shown from above (top view) in Diagram A, the Moon always looks completely bright in the view from Earth, as shown in Diagram B.
Is Felipe correct? If he is correct, explain why the Moon always looks bright from Earth in that position, and explain how he should show light on the Moon in Diagram A. If he is incorrect, explain how else the Moon can look when it is in that position.
