2. Today’s Agenda…3/3 Get your clickers Bellringer: Name the phases of the moon in order. Discuss Moon Log Review Notes on Eclipses

4. Let’s Review What causes day and night? –The Earth’s rotation on its axisThe Earth’s rotation on its axis –The Earth’s revolution around the sunThe Earth’s revolution around the sun –The Sun’s rotation on its axisThe Sun’s rotation on its axis –The Sun’s revolution around the EarthThe Sun’s revolution around the Earth

7. Let’s Review How long does it take the Earth to revolve around the sun? –1 day1 day –1 week1 week –1 month1 month –1 year1 year

9. Let’s Review What is Earth’s path as it revolves around the sun called? –AxisAxis –EclipseEclipse –OrbitOrbit –RotationRotation

11. Let’s Review What causes seasons on Earth? –The Earth gets closer to the sunThe Earth gets closer to the sun –The sun gets closer to the EarthThe sun gets closer to the Earth –The Earth is tilted on its axisThe Earth is tilted on its axis –The Earth rotatesThe Earth rotates

13. Let’s Review What event do the equinoxes mark? –Fall and springFall and spring –Winter and SummerWinter and Summer –Day and NightDay and Night

15. Let’s Review If the Northern hemisphere is tilted toward the sun, the North is experiencing –SummerSummer –WinterWinter –FallFall –SpringSpring

17. Let’s Review The phase of the moon depends on: –Where you are standing on EarthWhere you are standing on Earth –What the weather is like outsideWhat the weather is like outside –How much of the sunlit side faces EarthHow much of the sunlit side faces Earth

19. Today’s Goals! I can explain what causes an eclipse. I can compare solar and lunar eclipses.

20. Let’s see what you know… True or False –When the moon’s shadow hits Earth or Earth’s shadow hits the moon, an eclipse occurs

21. Let’s see what you know… True or False –The darkest part of a moon’s shadow during an eclipse is the penumbra

22. Let’s see what you know… True or False –Solar eclipses occur during a full moon

23. Let’s see what you know… True or False –A lunar eclipse occurs when the Earth is between the sun and moon

24. Let’s see what you know… True or False –A lunar eclipse can be seen anywhere on Earth that the moon is visible

25. Eclipses The sun, moon, and Earth do not usually line up in a straight line If this occurs a show can fall on the moon or Earth Most months the moon revolves around Earth without moving into Earth’s shadow or the moon’s shadow hitting Earth

26. Eclipses When the moon’s shadow hits Earth or Earth’s shadow hits the moon, an eclipse occurs There are two types of eclipses –Solar “sun” –Lunar “moon”

27. Solar Eclipses Happens during a new moon The moon passes between the sun and Earth The moon’s shadow hits Earth

28. Solar Eclipse The darkest part of the moon’s shadow is called the umbra –From this point the sun is completely blocked by the moon –People on Earth experience total solar eclipse –The sky is dark and you can see the stars!

29. Total Solar Eclipse

30. Solar Eclipse The larger part of the moon’s shadow that is less dark is the penumbra –People on Earth see a partial solar eclipse It’s never safe to look directly at a solar eclipse!

31. Lunar Eclipse Occurs at a full moon The Earth is directly between the sun and moon The Earth blocks sunlight from reaching the moon

32. Let’s see what you know… True or False –When the moon’s shadow hits Earth or Earth’s shadow hits the moon, an eclipse occurs

33. Let’s see what you know… True or False –The darkest part of a moon’s shadow during an eclipse is the penumbra

34. Let’s see what you know… True or False –Solar eclipses occur during a full moon

35. Let’s see what you know… True or False –A lunar eclipse occurs when the Earth is between the sun and moon

36. Let’s see what you know… True or False –A lunar eclipse can be seen anywhere on Earth that the moon is visible

37. Homework Create a Venn diagram to compare solar and lunar eclipses.
