• All planets in our Solar System ORBIT (revolve) the sun.

• Earth (like all planets) is tilted on its axis and rotates, causing day & night

causes day and night.

Multiple Choice

Ms. Garcia is teaching her science class about the solar system. She shines a flashlight on a globe as the globe is spinning on its axis. Which of the following best describes what Ms. Garcia's model demonstrates?

• Day and night are caused by the rotation of Earth on its axis.

• The seasons are caused by the tilt of Earth's axis.

• The phases of the moon are caused by Earth's orbit around the moon.

• The length of the year is caused by Earth's orbit around the sun.

Earth's Movement

• Earth and all other planets revolve around the sun (due to its gravitational pull)

• It takes Earth 365 days to revolve around the sun

Earth's Revolution

• Earth spins on its axis and completes one full rotation every 24 hours

• Earth's tilt causes seasons

• Rotation causes day & night

Earth's Rotation

Multiple Choice

What causes seasons?

• Earth's Revolution

• Earth's Rotation

• Earth's Tilt

• The Moon's Revolution

Stars & constellations appear to move across the night sky, but stars don't actually move!

Earth's rotation causes stars to appear shifted across the night sky.

Depending on where Earth is on its orbit, some constellations can be seen and some cannot.

Stars & Constellations

Earth's tilt causes seasons.

The part of Earth closest to the sun experiences summer.

The part of Earth farther from the sun experiences winter.

Seasons

The moon revolves around the Earth in a cycle that lasts 28 days.

The light reflected off of the moon by the sun gives us "moon phases"

Moon Phases

Multiple Choice

Which of the following is a reason that the constellation Orion is visible at night during some months, but not during others?

• Earth rotates on its axis.

• Earth revolves around the Sun.

• The constellations revolve around the Sun.

• The full moon makes the constellations hard to see.

• The phases of the moon repeat in order:

  • New Moon

  • First Quarter

  • Full Moon

  • Third Quarter

• A Full Moon occurs when the Earth is between the Sun and the Moon.

Draw a diagram of the Moon's position when it appears as Full from Earth.

(hint: include and label the Sun, Earth, and Moon)

Multiple Choice

Jaybary notices that on different nights, the shape of the Moon looks different. He decides to write down the phases of the Moon to find out how the Moon changes from night to night. If Jaybary writes down the phases of the Moon every night for 6 months, what will he find?

• There are more full moons than any other phase of the Moon.

• The phases of the Moon always occur in the same order.

• There are more new moons than any other phase of the Moon.

• The new moon always happens 29 days after a full moon.

Multiple Choice

What must happen for a new moon to occur?

• The sun must be between the Moon and Earth.

• Earth must be between the Moon and the Sun.

• Earth must be orbiting the Moon.

• The Moon must be between the Earth and the Sun.

Multiple Choice

Sunshina was watching her cat playing in the shadows as the Sun set. She wondered why we have day and night. Why does the Earth experience day and night?

• The moon rotates on its own axis.

• Earth rotates on its own axis.

• Earth revolves around the Sun.

• The Moon revolves around Earth.

Multiple Choice

The image shows the half moon that Judeley saw from his window last night. Which of the following accurately describes the moon as Judeley saw it?

• The Moon has completed 1/2 of its orbit around Earth since the new moon.

• The Moon has completed one full orbit around Earth since the last new moon.

• The Moon has completed 1/4 of its orbit around the Earth since the last full moon.

• The moon has completed 1/2 of its orbit around Earth since the last full moon.

Multiple Choice

What must happen in order for the Moon to appear full?

• Earth must be orbiting the Moon.

• The Sun must be between the Moon and the Earth.

• Earth must be between the Moon and the Sun.

• The Moon must be between Earth and the Sun.
