Space Science Review

Why do some stars appear bigger than others to us on Earth?

• The stars are just bigger.

• Bigger stars look bright so we think they are bigger.

• Some stars are closer to Earth which makes them appear bigger.

• All stars look the same size.

Why do some stars appear brighter than others even though they are actually duller?

• Duller stars always appear brighter.

• Some stars are closer to Earth so they look brighter.

• Bright stars use more energy so they look duller.

• All stars are the same brightness.

• A planet

You see an object in the sky. It is white in color and appears in the same spot every night. It looks the same sizes as the other objects around it. What did you see?

You are learning about new telescopes. What is the best question could you ask to see how they compare to old telescopes?

• Are these telescopes big?

• Are these telescopes in space?

• Do these telescopes take pictures in black and white or color?

• What material are the telescopes made of?

What are the strengths and limitations of this model?

• It attempts to show the order of the planets and shows their distance from each other.

• It attempts to show the size of the planets and their distance from each other.

• It attempts to show the order of the planets but does not show their size compared to each other.

• It attempts to show the distance of the planets but not their size comapred to each other.

What are the strengths and limitations of this model?

• It attempts to show the distance of the planets from each other.

• It attempts to show the size of the planets compared to each other but it does not show their distance.

• It attempts to show the order of the planets but does not show their size compared to each other.

• It is a perfect model.

What is the difference between stars and planets?

• Stars are small and planets are big.

• Stars are made of gas and planets can be mode of gas or rock.

• Planets are bigger than stars.

• Planets make their own light and stars do not.
