Practice:
When astronauts visit the Moon and look back at Earth, they see phases, too! Like the phases of the Moon that we see from Earth, the phases of Earth that astronauts see from the Moon are determined by the position of the Moon in its orbit around Earth. Today, you’re going to investigate the phases of Earth.
This photograph of Earth was taken by NASA astronauts from the Moon during the Apollo 8 mission in 1968. Which phase does Earth appear to be in?

Question 6

If space astronauts were to stay on the moon, how long would they have to wait to see the same Earth Phases as seen in the image above?
CFS:
Accurately identifies the light on the moon based on its position
Accurately describes the cause and effect relationship between rotational movements and illuminated objects
"I think if astronauts were to stay on the moon they would have to wait ____ days to see the same moon phase. this is because ... "
(Think: How long is the moon cycle/orbit?)

A student is modeling the moon phases and is trying to understand the timing when each phase occurs. Use the time stamps and images below to answer the following questions.
How can you predict the time the Moon will take to make 1 complete orbit?
CFS:
Accurately identifies the light on the moon based on its position
Accurately describes the cause and effect relationship between rotational movements and illuminated objects
"I think that the moon will take _______ minutes to make a complete orbit.
I think this because .... "
