  1. Teacher Notes • Globes and light sources should be used to have students model seasons, phases of the moon, and eclipses. • Recommended Strategy - The four part activity in the student packet may be completed as a Gallery Walk

  2. 1. Caleb’s class is studying the Earth/Sun/Moon system. He studies the diagram of Earth and the sun shown below. Which season is the northern hemisphere experiencing when Earth and sun are in these positions? A fall B winter C spring D summer 2. Maxine’s class is studying the Earth/Sun/Moon system. She studies the illustration of the moon, sun, and Earth shown below. At which stage is a solar eclipse possible? A 1 B 2 C 3 D 4

  3. How do the Sun, Moon, and Earth interact to create different observable features from the Earth?

  4. Seasons

  5. What causes seasons?BrainPop Video We know that the reason we have day and night is because the Earth rotates.

  6. Seasons revolves Look at this diagram. Notice how the Earth is always tilted in the same direction. As the Earth , the part of Earth tilted toward the sun changes.

  7. During what seasons is the North Pole tiled towards the sun? Why? summer

  8. During what seasons it the North Pole pointing away from the sun? Explain. winter

  9. How do tides change from high tide to low tide? • Two big bulges of water form on the Earth: • one directly under the moon • another on the exact opposite side As the Earth spins, the bulges follow the moon.

  10. Gravitational Effect of the Sun • Neap Tides • Earth, Moon, and Sun form right angles • High Tides are lower and Low Tides are higher than normal • Spring Tides • Earth, Moon, and Sun are lined up • High Tides are higher and Low Tides are lower than normal

  11. Solar Eclipses How do Eclipses differ from Phases of the moon? • When the Moon’s shadow covers part of the Earth • Only happens at New Moon

  12. Here is an animation showing a total solar eclipse

  13. This is an animation showing a total lunar eclipse from start to finish.

  14. The moon looks different throughout the month.Sketch a diagram of the Earth, Moon, and Sun that demonstrates how these phases occur.Next, we will test these diagrams. • Using a diagram of the Earth, Moon, and Sun, how can you determine the phase of the moon?

  15. Phases - Causes When the sunlight reflects off the Moon’s far side, we call it a New Moon When the sunlight reflects off on the Moon’s near side, we call it a Full Moon Between New and Full, we see parts of the daytime side of the Moon.

  16. Phases of the moon (Click and scan forward to the moon)

  17. Possible Extensions • Gizmos – • 2D Eclipse or 3D Eclipse • Phases of the Moon • Seasons: Why do we have Them? • Tides
