  • The Moon

  • The MoonWhat do we already know about the Moon?

  • Talk With Your Group!How do you think the Moon affects us here on Earth?

  • The effects of the MoonPhases of the moonEclipsesTides

  • Talk With Your Group!Why/How do you think Moon phases occur?

  • Why does the moon have phases?The changing relative positions of the moon, Earth, and sun cause the phases of the moon!

  • Talk With Your Group!Why do you think eclipses occur?

  • Why do eclipses occur?Sometimes the Earth, sun, and moon line up so that one object is blocking or shadowing another

  • Talk With Your Group!Why do you think we have tides?

  • Why does the Earth have tides?The sun and moon pull on the Earths water causing the tides to rise

  • Phases of the Moon

  • TidesPeriodic rise and fall of large bodies of water caused by the gravitational attraction of the moon to the Earth.

  • High TideOutward bulge of water. Occurs twice per day

  • Low TideTrough left by the movement of water to the two bulges. Occurs twice per day

  • Spring TideFull or new moon causes the gravity of sun and moon to combine causing extreme high and low tides

  • Neap tideMoon is in Quarter phase causing the gravity of the sun and moon to cancel each other. (Sun and moon pull at a right angle)Smaller difference between high and low tides

  • The tide cycleThe Tide Cycle

  • Tides: Rate Your Learning!Do you think you could explain tides to a friend? If so, then you are a 4!Could you Ace a quiz on tides? You are a 3!Do you want to study a little, then take a quiz? You are a 2!

  • The Moons Tilted OrbitThe moons orbit is tilted by 5 degrees, so it is infrequent for the sun, moon, and earth to all line up. When these objects do align, eclipses occur.

  • EclipseWhen the moons shadow hits Earth or Earths shadow hits the moon, an eclipse occurs

  • Types of EclipsesSolar eclipse solar is Latin for sunOccurs when the moon passes directly between Earth and the sun, blocking sunlight from EarthLunar eclipse- lunar is Latin for moonOccurs when Earth blocks sunlight from reaching the moon

  • Solar Eclipseumbrapenumbra

  • Total Solar EclipseLight from the sun is completely blocked by the moon; within the umbraUmbra- the very darkest part of the moons shadow on EarthPartial Solar EclipsePart of the sun is visible from Earth within the penumbraPenumbra- larger part of the moons shadow on Earth

  • Total Lunar EclipseWhen the moon is in Earths umbra, a total lunar eclipse occurs.Can be seen anywhere on Earth that the moon is visiblePartial Lunar EclipseOccurs when the moon passes partly into the umbra of Earths shadow; can appear orangeThe edge of the umbra appears blurry, and you can watch it pass across the moon for two or three hours.

  • Eclipses: Rate Your Learning!Do you think you could explain both Solar & Lunar Eclipses to a friend? If so, then you are a 4!Could you Ace a quiz on Eclipses? You are a 3!Do you want to study a little, then take a quiz? You are a 2!
