Understanding Earth and Moon Patterns

Why do the lengths of day and night change throughout the year?

• Because the Earth moves closer to the Sun.

• Because the Earth rotates on its axis.

• Because the Earth orbits the Sun and its axis is tilted.

• Because the Sun moves around the Earth.

Which of the following best explains how the Earth's tilt affects the seasons?

• The tilt causes different parts of the Earth to receive varying amounts of sunlight throughout the year.

• The tilt changes the distance between the Earth and the Sun.

• The tilt causes the Earth to spin faster in summer.

• The tilt makes the Earth wobble, creating seasons.

What is the phase of the moon when it is completely illuminated as seen from Earth?

• New Moon

• Crescent Moon

• Full Moon

• Quarter Moon

Develop a simple model to explain why the length of day and night changes throughout the year.

• Use a globe and a flashlight to show how the tilt of the Earth affects sunlight.

• Use a clock to show how time changes.

• Use a thermometer to measure temperature changes.

• Use a ruler to measure the distance from the Earth to the Sun.

Which phase of the moon comes after the new moon?

• Full Moon

• Crescent Moon

• Quarter Moon

• Gibbous Moon

How does the Earth's consistent tilt affect the length of daylight during different seasons?

• It causes the length of daylight to remain the same all year.

• It causes longer daylight in summer and shorter daylight in winter.

• It causes longer daylight in winter and shorter daylight in summer.

• It has no effect on the length of daylight.

Construct an explanation for why we experience different seasons.

• The Earth is closer to the Sun in summer and farther in winter.

• The Earth's tilt and orbit around the Sun cause varying sunlight angles.

• The Sun changes its brightness throughout the year.

• The Moon's phases affect the seasons.

What pattern do the phases of the moon follow?

• Random pattern

• Repeating pattern

• Increasing pattern

• Decreasing pattern

Why does the moon appear to change shape over the course of a month?

• The moon changes its size.

• The moon's orbit around the Earth causes different portions to be illuminated.

• The Earth blocks the moon's light.

• The Sun's light changes.

Develop a model to describe the phases of the moon.

• Use a ball and a lamp to show how the moon is illuminated by the Sun.

• Use a clock to show time passing.

• Use a thermometer to measure temperature changes.

• Use a ruler to measure the distance from the Earth to the Moon.
