Why does the sun appear to be the brightest star in the sky?

• Its apparent brightness is much greater than other stars.

• It is the largest star in the galaxy, so it is the brightest star.

• Its relative distance to Earth is closer than the other stars.

• It burns more gas, making it brighter than any other star.

What is the apparent brightness of a star?

• How bright it actually is

• How bright it is compared to the sun

• How bright it is from Earth

• How bright it is from a certain distance

What causes a repeating pattern of day and night?

• The Earth rotates on its axis over 24 hours.

• The Earth orbits, or revolves, around the sun.

• The sun changes its position around the Earth.

• The Earth is facing different parts of the sun as the day goes on.

Richard made the following table that highlights all the different constellations, or patterns of stars, he observed in each season of the year. Which statement is true?

• The rotation of the Earth determines the constellations seen in each season.

• The constellations seen in each season depend on the movement of the stars.

• The revolution of the sun allows you to see different constellations throughout the year.

• In each season, you see different constellations due to the orbit of the Earth around the sun.

Explain how the sun's position in the sky affects the length of shadows.

• The lower the sun in the sky, the longer the shadows are. At 12 noon the shadows are the shortest.

• The lower the sun in the sky, the shorter the shadows are. At 12 noon the shadows are the longest.

Explain how the sun's position in the sky would change the direction of your shadow if you were to stand in the same place all day.

• If the sun is in the east, the shadow of the object will be in the west.

• If the sun is in the north, the shadow of the object will be in the east.

• If the sun is in the west, the shadow of the object will be in the west.

• If the sun is in the south, the shadow of the object will be in the east.

An object's shadow was observed and measured at different times of the day. The data was recorded in the chart below. How does the data provide evidence that the sun is changing position in the sky throughout the day?

• The shadows are shorter at the beginning and ending of the day and longest at noon.

• The shadows are longer at the beginning and ending of the day and shortest at noon.

• The shadows are longer at the beginning and middle of the day and shortest at end of the day.

• The shadows are longer at the ending of the day and at noon and shortest at the beginning of the day.
