What question could you ask to determine which tool was used to discover Jupiter’s red storm for the first time?

Why do some stars, including the Earth's sun, appear larger or brighter than others?

• Because they are older

• Because they are closer or larger

• Because they are newer

• Because they are in a different stage

Which argument best explains why some stars appear to be larger and brighter than others?

• If one star is closer to the earth than another, then it will appear larger and brighter. If two stars are the same distance from the earth, the larger star will appear brighter.

• When a person on earth looks at the stars in the night sky, if one star is further away from the earth than another, then it will appear larger and brighter. If two stars are the same distance from the earth, the larger star will appear brighter.

• When a person on earth looks at the stars in the night sky, if one star is closer to the earth than another, then it will appear larger and brighter. If two stars are the same distance from the earth, the smaller star will appear brighter.

• When a person on earth looks at the stars in the night sky, if one star is further away from the earth than another, then it will appear smaller and brighter. If two stars are the same distance from the earth, the smaller star will appear brighter.

Why does the sun appear so big and bright compared to other stars?

• The sun is not really a star. It is a sun and that’s why it is so big and bright.

• Since the sun is the closest star to the earth, it appears bigger and brighter than the other stars.

• The sun is brighter than all the other stars in the sky, so it looks bigger from the earth even though it is really farther away than most stars.

• The sun is a star, but it is made up of gases that are much different from the other stars and this makes it appear bigger and brighter than the other stars.

Two fourth grade boys are looking at the night sky with a telescope and notice some stars are brighter and bigger than other stars. Which statement BEST explains why some stars are brighter and bigger?

• The stars are brighter than other stars because they are physically brighter.

• The stars appear bigger and brighter because of their closeness to the Earth.

• The stars appear bigger and brighter because of their closeness to surrounding stars.
