Earth Moon Sun Moon Phases Eclipses Essential Standards

Earth, Moon & Sun Moon Phases & Eclipses

Essential Standards • 6. E. 1 Understand the earth/moon/sun system, and the properties, structures and predictable motions of celestial bodies in the Universe.

Clarifying Objectives • 6. E. 1. 1 Explain how the relative motion and relative position of the sun, Earth and moon affect the seasons, tides, phases of the moon, and eclipses.

Essential Questions • How do the phases of the moon change as it REVOLVES around the Earth? • What are the positions of the sun, moon, & Earth during a solar & lunar eclipse? • How does rotation & revolution of the Earth affect units of time on Earth?

Phases of the Moon • The Earth is revolving around the sun • The moon is revolving around the Earth • The MOONS CHANGING IN POSITION IN RELATION TO THE SUN & THE EARTH causes moon phases • http: //www. youtube. com /watch? v=0 v. XWXq. Gm. PCk

Phases of the Moon • The moon is circling the Earth so we can only see part of the moon • Half of the moon is always lit up • Moonlight is just the sun’s light reflecting off the moon & into your eyes • http: //www. youtube. com /watch? v=Laqr. Qy. Tm 9 B 4 • 5: 11 -6: 20

Phases of the Moon • When the moon is in between the sun & the Earth we CAN’T see the moon • When the Earth is in between the sun & the moon we can see all of the lit side of the moon

Phases of the Moon • The moon cycles from New moon to Full moon every 29. 5 days • That is = to 1 month • We get our MONTHS from the Revolutions of the moon

Phases of the Moon • http: //www. youtube. com/watch? v=Laqr. Qy. T m 9 B 4 • 1: 17 -4: 15

Essential Question? ? • Get with a partner or group and answer… • How do the phases of the moon change as it REVOLVES around the Earth? • Why do we see different phases of the moon?

Eclipses • Eclipses are what happen when the Earth casts a shadow on the moon or the moon casts a shadow on the Earth • AN ECLIPSE IS WHENEVER SUNLIGHT IS BLOCKED • When the Earth casts a shadow on the moon we have a LUNAR ECLIPSE • When the moon casts it’s shadow on the Earth we have a SOLAR ECLIPSE • http: //www. youtube. com/wat ch? v=Laqr. Qy. Tm 9 B 4 • 10: 07 -11: 59

Lunar Eclipse • AN ECLIPSE IS WHENEVER SUNLIGHT IS BLOCKED • When the Earth casts a shadow on the moon we have a LUNAR ECLIPSE

Solar Eclipse • AN ECLIPSE IS WHENEVER SUNLIGHT IS BLOCKED • http: //www. youtube. co m/watch? v=Laqr. Qy. Tm 9 B 4 • When the moon casts • 10: 07 -11: 59 it’s shadow on the Earth we have a SOLAR ECLIPSE

Why don’t we get Eclipses every Month • We don’t get eclipses every month because the moon’s orbit is TILTED • If it was a straight line orbit we would get both a lunar & a solar eclipse every month • http: //www. youtube. co m/watch? v=Laqr. Qy. Tm 9 B 4 • 10: 07 -10: 51

Essential Question • Get with a partner or group and answer… • What are the positions of the sun, moon, & Earth during a solar & lunar eclipse?

EOG Questions • Which best explains why the moon has phases? • A) The moon’s position changes in relation to the sun and Earth. • B) The sun’s position changes in relation to the moon and Earth. • C) The Earth casts a shadow on the moon as it rotates. • D) The moon rotates along its axis.

Important Points • Moon phases happen because the MOON CHANGES POSITIONS as it revolves around the Earth • When you can’t see the moon it is called a NEW MOON • AN ECLIPSE IS WHENEVER SUNLIGHT IS BLOCKED • When the moon casts it’s shadow on the Earth we have a SOLAR ECLIPSE • When you see whole moon it is called a FULL MOON • When the Earth casts a shadow on the moon we have a LUNAR ECLIPSE • The moon makes a revolution around the Earth every 29. 5 days which is why we have a month • Moonlight is sunlight REFLECTING off the moon into your eyes
