Grade 8 Unit 06: Sun, Earth, and Moon
- 1. Describe how Earth's tilted axis and orbit around the sun, result in seasonal weather patterns.
- 2. The same side of the moon is always facing Earth. How is that possible, considering it revolves around the Earth? Cool GIF of view of Moon from Earth and explanation of tidal lock and a quick useful video explaining tidal lock
- 3. Sometimes, from Earth, we see the Moon fully illuminated, and sometimes it is completely dark and obscured, and everything between. Why? Sometimes, when the Moon is visible, we see it at night, and at other times during the day. Why? Watch the video and try this at home How will you memorize the phases of the moon? I use DOC
- 4.Describe the phases of the moon using the following: new, crescent, gibbous, full, waxing, waning, 1st, 2nd, 3rd, and 4th quarter. Helpful video
- 5. What is the difference between neap and spring tides? Why does the moon have a greater effect on the tides even though it is much smaller and less massive than the sun? How will you remember (memorize) which is the spring tide and which is the neap tide? Click here for a really good illustration of the tides.
- 6. You should be able to draw a picture of the Moon phases in relationship to the Earth and Sun. Consider the following question: Could you ever see a full moon during the day? By the end of the unit, it should be obvious the answer is no, even without a picture, but what about the following: When would you see a waxing crescent moon, in the morning, or in the evening? Would the moon be ahead of the sun, or behind it? Use Solar System Scope to help you figure out the answer.
- 7. In the United States, many of our Christmas songs have to do with snow and wintry fun. Why might these Christmas songs confuse an Australian child?
