Earth, Moon, and Sun Friday Checkpoint

Question 1

• 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.
• 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.
• 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.
• 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.

Question 2

• 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.
• Between the first observation and the second observation, the Moon moved closer to the sun so more sunlight reached the Moon’s surface.
• 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.
• Between the first observation and the second observation, Earth’s shadow moved and was blocking less of the Moon so Tania was able to see more of it.

Question 4

• Light travels in straight lines only.
• Light travels like a river, wherever there is an open path.
• Light travels in unpredictable ways.
• It depends; if the light is bright enough it can change direction.

Question 5

• About one week.
• About one month.
• There is no way to tell because the Moon’s pattern is always changing.
• It could be two weeks or a month, depending on what time of year it is.

Question 6

• Diagram A is accurate because the whole Moon is bright as long as there are no shadows covering parts of it.
• 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.
• 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.
• 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.

Question 7

• Between the first photograph and the second photograph, the Moon moved farther away from the sun so less sunlight reached the Moon’s surface.
• Between the first photograph and the second photograph, Earth moved so its shadow was blocking more of the Moon so the student astronomer was able to see less of it.
• Between the first photograph and the second photograph, the Moon rotated so that less of the light-colored rock on the Moon’s surface faced Earth.
• Between the first photograph and the second photograph, the Moon moved so that the student astronomer was able to see less of the half that faces the sun.

Question 9

• The Moon is always moving around Earth in a circle.
• The Moon is always in the same position in Earth’s sky.
• The Moon is always moving in many changing patterns around Earth.
• The Moon is always moving back and forth across Earth’s sky.

Question 10

• No, light travels in straight lines only.
• Yes, light travels like a river, wherever there is an open path.
• Maybe; light travels in unpredictable ways.
• Yes, if the light is bright enough, then it can change direction to go around corners.

Question 11

• Diagram A is accurate because the Moon is almost as far as it can be from the sun, so almost none of the Moon is lit by the sun.
• Diagram B is accurate because the half of the Moon that is facing the sun is lit by the sun, and the other half is dark.
• Diagram C is accurate because the whole Moon is bright as long as there are no shadows covering parts of it.
• 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.
