Which of the following explanations correctly compares planets and stars?

Stars can be seen in the sky at night and planets cannot

Planets are made of gas and plasma; Stars are made of gas or rock

A student constructs the following explanation to compare planets and stars: Stars are much larger than planets, and they also have have gas in their composition, which planets do not. Nearby planets can sometimes be seen in the night sky, but stars can be very far away and still seen in the night sky because they emit light. Finally, planets orbit around stars. Which of the following changes would improve the student’s explanation the most?

Some planets also have gas in their composition, but not all planets.

Planets cannot be seen in the night sky, but stars can.

Some stars are larger than planets, but not all of them.

The teacher observes the notes and asks the student to give Label A and Label B the correct headings. Which of the following would the student fill in and why?

Label A is a star because stars constantly twinkle since they always give off light. Label B is a planet because planets do not give off their own light.

Label A is a star because stars constantly twinkle since they always give off light. Label B is a planet because planets are either made out of gases or rocks.

Label A is a planet because it is made out of hot helium. Label B is a run because all suns are made out of hot rocks.

Label A is a planet because it gives off light. Label B is a star because all stars reflect light and twinkle in the night.

Why do planets appear to move across the constellations at different times and locations compared to stars?

Planets are much closer to the Earth than stars.

Planets orbit around the Earth.

Planets move the same speed as all stars.

Planets do not move, it just appears that they do because the stars are moving.

A student is completing research about how stars are different from planets. Which of the following descriptions could the student conclude from the research?

Stars are made out of gases and give off a light.

Stars are evenly spread out in the sky because of their orbits.

Stars orbit around planets that they are close to.

Stars each have one moon that orbits around it.

Which of the following is accurate information that can be placed inside the chart?

Stars have much higher temperatures than planets since stars emit light and energy.

You must use a telescope in order to see stars at night. You can see all planets at the same time when observing without any technology.

Planets twinkle in the night sky and stars are dim.

Planets and stars are very similar, but the only difference is that planets orbit stars.

A model of the solar system is shown. Which of the following is a strength of the solar system model below?

The model attempts to show the differences in how the planets look

The model attempts to show the size of the planets to scale

The model attempts to show the composition of the planets

The model attempts to show the distance between the planets to scale

What limitations does the model have?

It does not show how the relative size or show that the planets orbit around the Sun.

It does not show the order of the planets from the Sun or the composition of the planets.

It does not show how the planets orbit around the Sun or the composition of the planets.

It does not show the composition of the planets or the relative size.

A group of fourth graders are wanting to build a solar system model. Which of the following characteristics of the model should the student include to make it as representational of the real solar system as possible?

The model should show an orbit with the correct order with relative distances from the Sun and relative sizes.

The model should show how the planets all orbit around the Sun at the same speed while showing relative sizes and distances from the Sun.

The model should show the order from first to last on a poster board with texture to represent the composition.

The model must be 3D to show that the solar system is also 3D.

How many miles is Jupiter from Earth?

Has a human ever landed on Jupiter?

Was the storm discovered from the surface of Jupiter, or from space?

A student wonders what technology was used to take this picture and discover what the surface of Mercury looks like. She asks:

Was this photograph take from Earth or from the surface of Mercury? If it was taken from Earth, I know a telescope must have been used. If it was taken from Mercury, I know that a rover/robot must have been used.

She should also ask if the picture was taken from space, because it could have been taken by an astronaut who traveled to Mercury

She should also ask if the photo is color or black-and-white, because it could have been taken by an astronaut who traveled to Mercury

She should also ask if the picture was taken from space, because it could have been taken by a probe passing Mercury

She should also ask if the photo is color or black-and-white, because it could have been taken by a probe passing Mercury

Kate and Sam are outside on a perfectly clear night, looking up at the stars. They are discussing what they learned about stars in science class today. Kate says she is still confused as to why some stars are brighter than others. She asks Sam if he could explain. Which argument is the best to explain 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.

During recess, Tony and Josephine were talking about the sun and stars. Tony told Josephine that the sun is really a star. Josephine asked why it was so big and bright. If the sun is a star why is it so big and bright?

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 gasses that are much different from the other stars and this makes it appear bigger and brighter than the other stars.
