1. Leticia 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 Leticia’s diagram show that it’s brighter on the left half of the Moon?
a)
A. Because as the Moon gets closer to the sun more of it is lit by the sun, so Leticia’s diagram is showing sunlight on half of the Moon.
b)
B. Because the Moon has some lighter-colored rock and some darker-colored rock, and Leticia’s diagram is showing that the half of the Moon with the lighter-colored rock has rotated to the left.
c)
C. Because Leticia’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.
d)
D. Because there is a shadow from Earth falling on half of the Moon, and Leticia’s diagram is showing that shadow on the right half of the Moon.

2. Tania went outside and made two observations of the Moon that were several days apart. Her observations are shown in the diagram below. The light part of the Moon appeared to get larger over time. Why did this happen?
a)
A. Between the first observation and the second observation, the Moon moved so that Tania was able to see more of the half that faces the sun.
b)
B. Between the first observation and the second observation, the Moon moved closer to the sun so more sunlight reached the Moon’s surface.
c)
C. 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.
d)
D. Between the first observation and the second observation, Earth moved so its shadow was blocking less of the Moon so Tania was able to see more of it.

3. The diagrams below show Earth and the Moon in different positions, as seen from above (top view). Sunlight is coming from the left, but these diagrams do not show what parts of Earth or the Moon are light or dark. Could the half of the Moon that faces Earth ever be completely dark in any of these diagrams?
a)
A. No, the Moon is always completely lit by the sun.
b)
B. Yes, always in Diagrams 2 and 3, but never in Diagram 1.
c)
C. Yes, always in Diagram 2, but never in Diagrams 1 or 3.

6. Three students made the diagrams below 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?
a)
A. Diagram A is accurate because the whole Moon is bright as long as there are no shadows covering parts of it.
b)
B. Diagram B is accurate because the Moon is almost as close as it can be to the sun, so the Moon is almost fully lit by the sun.
c)
C. Diagram C is accurate because the half of the Moon that is facing the sun is lit by the sun, and the other half is dark.
d)
D. All three diagrams are sometimes accurate because the Moon has some lighter-colored rock and some darker-colored rock, and the half of the Moon with the lighter-colored rock rotates to face different directions.
