Students will understand the effects of the relative positions of the earth, moon and sun. • a. Demonstrate the phases of the moon by showing the alignment of the earth, moon, and sun. • b. Explain the alignment of the earth, moon, and sun during solar and lunar eclipses. It takes 29.5 days for the moon to revolve around the Earth and we always see that same side of the moon. (We never see the back side) INTRODUCTION Different amounts of sunlight light up the moon and, from Earth, makes the moon appear to have “different shapes” or phases. Why do we have MOON PHASES? How big is the Moon? • Wall-e Learns about Proportions Check what you know: Seeing the Moon How often have you looked up into the sky and seen the Moon? Put an X next to all the times when you think you can go outside and see the Moon. ____ in the morning ____ at noon ____ in the middle of the afternoon ____ in the evening before sunset ____ in the evening after sunset ____ at midnight Uncovering Student Ideas in Astronomy pg 91 What do we see? The Phases of the Moon – New moon: (0% None reflected light) – Crescent: (1-49% partly but less than one- half illuminated by direct sunlight.) – Quarter: (50% half) Draw it Draw it! Draw it! The Phases of the Moon – Gibbous: (51-99% more than one-half but not fully illuminated by direct sunlight. ) – Full moon: (100% ALL illuminated by direct sunlight.) Draw it! Draw it! Why do we see “phases” of the moon? VIDEO= SEE END FOR DIRECTIONS! • Lunar Phase Simulator • Moon Phases BrainPoP • Animated picture of Moon phases Check what you know: Crescent Moon When there is a crescent Moon in the night sky, how much of the entire Moon’s spherical surface is actually lit by the Sun? Circle the answer that best matches your thinking. A. Quarter or less of the entire Moon B. Half of the entire Moon C. Three quarters of the entire Moon D. The entire Moon Uncovering Student Ideas in Astronomy pg 127 Check what you know: Moon Phase and Solar Eclipse During a solar eclipse the Moon appears to completely cover the Sun. What phase is the Moon in just before and after a solar eclipse? Circle the answer that best matches your thinking. A. Full Moon B. New Moon C. First quarter Moon D. Last quarter Moon E. It can be any phase. Now, draw a diagram of where the Earth, Moon and Sun will be during a SOLAR eclipse. Uncovering Student Ideas in Astronomy pg 109 Solar Eclipse OTe PE ROLES Fae om UU MOUSE cea eeu sunlight from reaching part of Earth's surface, in July of 1991, Solar Eclipses • Sun – the shadow of the moon on the earth Total solar eclipse in 1999 Cause: Earth passes between the sun and the moon Effect: Earth’s shadow falls on the moon. Eclipses • Have you seen eclipses? • What are eclipses in nature? – One celestial object casts its shadow on the other one • Umbra: Inner core of total darkness the disc of the Sun is completely blocked. • Penumbra: Outer, partial shadow Sun's disc is only partly blocked, with a bit peeking over the edge. What’s the moon phase when a solar eclipse occurs? What’s the moon phase when a lunar eclipse occurs?
