What is rotation?

• Earth traveling around the sun, which takes 365 days
• Earth spinning on its invisible axis, which takes 24 hours

Why do we experience day and night on Earth?

• The moon and stars revolve around the Earth, causing Earth to see them only at certain times
• The moon reflects light from the sun
• The Earth rotates on its axis every 24 hours, so half of the Earth is always in darkness (night) and half is always in sunlight (day)

Why do we only see some constellations at certain times of the year?

• The Earth changes its position in space as it revolves around the sun
• Constellations revolve around the sun at different speeds
• All constellations can be seen any time of the year, you just need a telescope

What is revolution?

• Earth traveling around the sun, which takes about 365 days
• Earth spinning on its invisible axis, which takes 24 hours

Why is the sun so much brighter than the other stars in the sky?

• The sun is brighter because we see it during the day
• The sun is brighter because it is so hot
• The sun is brighter because it is bigger than all other stars
• The sun appears brightest because it is much closer to Earth than any other star

What causes the phases of the moon?

• Clouds cover part of the moon, so we can't always see the full lit surface of the moon.

• As the moon orbits Earth, we see the lit part of the Moon's surface at different angles.

• As the moon revolves around the sun, it's lit up in different amounts.

• Earth's shadow falls on the moon in different angles.
