1. Lunar (moon) Phases

2. AGENDA 11/19 1. lecture 2. video 3. Processing task HOMEWORK Catalyst 1.What do you know about the Earth, sun, and moon? 2.What is an orbit? Assignment #1 (New Unit: Space) Lunar (Moon) Phases LO: To create a model to compare the orbits of the Earth, moon, and sun. EQ: Why are there phases of the moon? What causes the moon to shine?

3. What is an orbit? Orbit: curved path of an object around a sun, planet, or moon Earth’s orbit is an ellipse (oval)

4. We see the moon because it reflects the light of the Sun. Reflection: Light from the sun bounces off the moon’s surface.

5. Half of the Moon is always lit up by the sun. As the Moon orbits the Earth, we see different parts of the lighted area. http://www.nasm.si.edu/apollo30th/moontheater/phasepage2.html

6. Watch the demonstration… Draw 6 boxes across your page (4 lines) http://www.nasm.si.edu/apollo30th/moontheater/phasepage2.html

7. The revolution of the Moon around Earth makes it appear as if its changing shape. http://btc.montana.edu/ceres/html/birthdayphases.htm

8. As the moon orbits around the Earth, our angle to it changes so it looks like the light is changing shape http://btc.montana.edu/ceres/html/birthdayphases.htm

9. This is caused by the different angles from which we see the lighted part of the Moon's surface (where sunlight is reflected). These are called "phases" of the Moon. http://btc.montana.edu/ceres/html/birthdayphases.htm

10. The Moon passes through 8 phases during a cycle that repeats itself approximately every 28 days. The phases always follow one another in the same order: New moon Waxing Crescent First quarter Waxing Gibbous Full Moon Waning Gibbous Last Quarter Waning Crescent

11. Draw curved lines and arrows AND words to illustrate orbit and reflection (include ALL new vocabulary)

12. Orbit of the sun, Earth, and moon. Describe what you see in class.

13. Orbit of the sun, Earth, and moon. Describe what you see in class. The moon orbits the Earth. The Earth orbits the sun.

14. https://www.youtube.com/wa tch?v=NCweccNOaqo Watch video about lunar phases

15. Lunar Phases Phases of the Moon: different angles from which we see the lighted part of the Moon's surface. There are 8 different phases.

17. Waxing: growing moon Waning: shrinking moon http://www.nasm.si.edu/apollo30th/moontheater/phasepage4.html

19. Processing Task: color, label and attach the Lunar Phases model as shown below. Every 27.3 days

20. L.O. - ISN p 15 I can describe changes in the appearance of the moon during a month and identify the pattern of change in the moon’s appearance.
