none of the moon
30s - Q2
From Earth we can only see the half of the Moon that is facing us.
truefalseTrue or False30s - Q3
The reason there is a pattern to the position of the Moon is because the Moon rotates on its axis.
falsetrueTrue or False30s - Q4
The reason we see different phases of the moon is because we see different amounts of the illuminated half as the Moon moves around Earth.
truefalseTrue or False30s - Q5
It takes about one month for the Moon to orbit, so the pattern of moon phases repeats every month.
truefalseTrue or False30s - Q6
Susan is a space scientist who made this diagram of the Moon and Earth, as seen from above (top view), with sunlight coming from the left, as shown by the arrows. Why does Susan’s diagram show that it’s bright on the left half of the Moon?
Because as the Moon gets closer to the sun more of it is lit by the sun, so Susan’s diagram is showing sunlight on half of the Moon
Because Susan’s diagram is showing that the half of the Moon that is facing the sun is lit by the sun, and the other half is dark.
Because there is a shadow from Earth falling on half of the Moon, and Susan’s diagram is showing that shadow on the right half of the Moon.
120s - Q7
Astronomers made two observations of the Moon that were several days apart. Their observations are shown in the diagram above. The light part of the Moon appeared to get larger over time. Why did this happen?
Between the first observation and the second observation, Earth moved so its shadow was blocking less of the Moon so the astronomers were able to see more of it.
Between the first observation and the second observation, the Moon moved so that the astronomers were able to see more of the half that faces the sun.
Between the first observation and the second observation, the Moon rotated so that more of the light-colored rock on the Moon’s surface faced Earth.
120s - Q8
Three people made the diagrams above to show what they think the Moon looks like when it is seen from above (top view). In these diagrams, the sunlight is coming from the left, as shown by the arrows. Which diagram is accurate and why?
Diagram B is accurate because the whole Moon is bright as long as there are no shadows covering parts of it.
Diagram C is accurate because the Moon is almost as close as it can be to the sun, and so the Moon is almost fully lit by the sun.
Diagram A is accurate because the half of the Moon that is facing the sun is lit by the sun, and the other half is dark.
120s - Q9
Suki looked up one night and saw a crescent moon.If Suki looks for the Moon again in one month, what will he see?
Suki could see either a crescent or a quarter moon; it depends on the time of year.
Suki will see a crescent moon again, like Diagram A.
Suki will see a quarter moon, like Diagram B.

120s - Q12
Shira looked up one night and saw a full moon. How long will it be before she can see a full moon again?
About one month.
