Phases, Eclipses, and Tides

1. Phases, Eclipses, and Tides

2. Brainstorming/Reflection • Explain the difference between the New Moon and a Full Moon.

3. The positions of the moon, Earth, and the sun cause the phases of the moon, eclipses, and tides.

4. The Moon’s Orbit • The Moon revolves around Earth and rotates on its axis. • It’s orbit is a flattened circle or oval-shape.

5. Moon Phases • The moon goes through its whole set of phases each time it revolves around Earth (once a month). • Phases are caused by changes in the relative positions of the moon, Earth, and the sun.

6. The sun lights the moon, so half of the moon is almost always in sunlight. • However, since the moon revolves around the earth, you see the moon from different angles.

9. What Causes Tides? • The force of gravity pulls the moon and Earth (including the water on Earth’s surface) toward each other. • Tides occur mainly because of differenced in how much the moon pulls on different parts of Earth.
