How does this model help to explain seasons on Earth?

• a. It shows how Earth’s rotation affects the amount of direct sunlight an area receives.

• b. It correctly shows the distance from the Earth to the Sun and how that is what causes seasons

• c. It shows how Earth’s tilt and orbit around the sun affect the amount of direct sunlight an area receives causes seasons.

• d. It correctly shows how the size of Earth in relation to the sun and that is what causes seasons..

What can you conclude from this diagram about the particular season for the Northern Hemisphere?

• a. The Northern Hemisphere is tilted toward the sun and therefore is experiencing winter.

• b. The Northern Hemisphere is tilted toward the sun and therefore is experiencing summer.

• c. The Northern Hemisphere is tilted away from the sun and therefore is experiencing winter.

• d. The Northern Hemisphere is tilted away from the sun and therefore is experiencing summer.

Several students in a science class are trying to explain what the arrow in the image represents and how it affects the orbit of the planet. Which student’s explanation is the most accurate?

• a. Cassie - The force of gravity from the sun pushes Earth back in its revolution of other planets.

• b. Yong - The force of gravity from Earth and other planets causes them to orbit around the sun.

• c. Gertrude - The force of gravity from Earth pulls on the sun and causes the sun to move in a circular orbit.

• d. Jayden - The force of gravity from the sun pulls on Earth and causes Earth to move in a circular orbit

Which of the following could the model be used to determine? (Select all that apply)

• a. the solar system to scale (all the objects are the correct sizes and distances)

• b. which planet has the longest day

• c. which planet moves fastest in its orbit because closer planets orbit faster

• d. which planet likely has the longest year, because farther planets take longer to orbit the Sun

Astronauts in protective space suits can work outside the International Space station. Their suits are equipped with radios that allow them to communicate with colleagues inside the space station and with mission controllers on Earth’s surface. Why must two astronauts working outside the station also use radios to hear each other, even if they are very close together?

• a. It is noisy in orbit.

• b. Sound travels too slowly in space.

• c. Conditions in space distort sounds, making them difficult to recognize.

• d. Speech requires sound, which must travel through matter such as air or water, and there is no such matter in space.

Which statement about the model is true?

• a. It accurately shows the LACK of empty space in the solar system.

• b. The sun is actually smaller than the planets in the solar system.

• c. The sizes of the planets in relation to each other are accurately represented in the model.

• d. The only accurate thing is the order of the planets, and the Sun is the largest thing in the solar system.

Which of the following is shown in the model? (a)  

• a. a solar eclipse
• b. a lunar eclipse
• c. winter solstice
• d. summer solstice

Based on Leonore’s model, how will the moon appear to Reo?

• a. He will not see the moon at all.

• b. He will see a waning crescent moon.

• c. He will see the same crescent moon.

• d. He will see a moon that is not lit up.
