Lesson 6
Moon Phases
Learning Intention: Relate the phases of the moon to its relationship to the sun and earth.
Success Criteria
9. I can compare the phases of the moon with reference to amount of light and relative positions of the moon, earth, and sun.
A = Identifies facts about the moon phases (e.g. cause, positions of sun/earth/moon)
M = Explains some phases
E = Full justification
10. I can explain the rise and set of the moon in reference to its orbit relative to the sun and earth's spin.
M = explains different rising time, no linkage
E = full justification with linkage to time examples provided
11. I can explain why the moon phases is 29.5 days but the moon's orbit around the earth is only 27.3 days.
A = identifies difference in moon phases vs orbit time
M = explains the reason for the difference
Learning Tasks
First, it's important that we do some introductory videos to cover the basics.
Why does the moon appear upside down in different hemispheres? - Watch Stargazing EdPuzzle to learn why.
Why do you only see the same side of the moon? - Watch these two EdPuzzles to find out why. Video 1 and Video 2
Watch the National Science Teaching Association video on the Moon Phase Demonstration. Note that this demo is for the Northern Hemisphere Moon Phases.
Open up both the Northern Hemisphere Moon Phases and Southern Hemisphere Moon Phases. Put one on each screen and play it at the same time. Compare what is similar and different.
Use the Earth Space Lab Moon Phases Simulation (set to Southern hemisphere) and the terms used in the National Science Teaching Association video to fill in a diagram showing the phases of the moon in reference to the Southern hemisphere. Summarize on that piece of paper what causes the difference phases of the moon?
Use the PBS Learning Lunar Phase Simulation to answer the two questions below. Note that both these simulations are for the Northern hemisphere.
Why can we see the moon during the day time?
Why do you think the rise and set of the moon varies in reference to the rise and set of the sun?
Consider the following, it only takes the moon 27.3 days to orbit the Earth, yet the moon phases are 29.5 days. Why do you think there is about an extra 2 days? Going back to the PhET Gravity and Orbits simulation might help you answer this question.

Homework
This lesson took place from Thursday, August 29th, 2024, Term 3 Week 6 to Tuesday, September 3rd, 2024, Term 3 Week 7. The latter is when this page was last updated.
Teacher Notes
Ideally for next time, I want to better plan out lessons 1 and 2 so they cut better. They're not well defined.
