Gravity and Stars Quiz

Considering the information about various stars, why does the Sun appear so bright and large to us on Earth?

• Because the Sun is the largest star in the galaxy.

• Because the Sun is made of different materials than other stars.

• Because the Sun is closer to Earth than other stars.

• Because the Sun is the only star that produces light.

Chrissy understands stars are not visible during the day. Using a diagram of the Earth and Sun, how can she explain this?

• "The Sun's brightness during the day outshines other stars, making them invisible to us."

• "Stars only come out at night."

• "During the day, Earth faces away from the stars."

• "The Sun blocks our view of the stars during the day."

Why might Xenia not have been able to see the constellation Orion during her summer camping trip?

• The campfire's light was too bright, making it hard to see the stars.

• Orion is only visible during the daytime.

• Orion is a winter constellation and not visible in summer's night sky.

• The Sun's brightness at night prevented her from seeing Orion.

If the student standing with the larger, blue ball representing a bigger star takes 15 steps backward, what outcome is NOT possible?

• The two balls might appear to be the same size.

• The larger ball will seem smaller than before.

• The smaller, yellow ball appears to shrink.

• The smaller ball might look larger than the bigger ball.

What does gravity do to a ball when you throw it into the air?

• Gravity pulls the ball higher into the sky.

• Gravity pulls the ball back down to the ground.

• Gravity has no effect on the ball once it leaves your hand.

• Gravity pushes the ball sideways as it moves through the air.

How can nighttime occur at Sakura's location on Earth?

• Earth rotates on its axis, moving her location away from the Sun.

• Earth orbits the Sun, moving Sakura's location into the Sun's shadow.

• The moon orbits Earth, casting a shadow over Sakura's location.

• The Sun moves behind the moon, blocking light from reaching Sakura's location.

To show gravity's existence, what could students observe?

• A balloon floating away into the sky.

• An apple falling from a tree.

• Leaves being blown across the ground by the wind.

• A paper airplane flying across the room.

Which statement is accurate about the visibility of stars from Earth throughout the year?

• "We see different stars each night because Earth faces various directions as it rotates."

• "As Earth orbits the Sun, we face different directions in space at different times of the year, seeing different stars."

• "The same stars are visible every night because they surround the Earth."

• "The Earth's consistent upright position allows us to see the same stars every night."

What explains the daily patterns of day and night?

• The moon's rotation around Earth.

• The varying strength of the Sun's rays.

• Earth's orbit around the Sun.

• Earth's rotation on its axis.

Which experiment best demonstrates the effects of Earth's gravity on objects of different masses?

• Dropping a feather and a rock from the same height to see which lands first.

• Placing objects of different weights on a scale to compare their masses.

• Dropping two balls of different masses from the same height to see if they land at the same time.

• Throwing two balls of different masses into the air to see which goes higher.
