Blog Post Week 6, Earth, Sun and Moon
What did you do in lab today? What was the big question?
How do the phases of the moon occur?
The earth moves around the sun, and the sun is shining light differently on the earth, therefore the moon is being shown differently according to the position of the earth in relation to the sun.
What causes the seasons?
The earth gets closer and further away from the sun, so it is getting hotter and colder as it moves further and closer.
What causes a lunar eclipse?
When the sun and the moon are in the same position in relation to looking at it from the earth.
The big question that was addressed in lab today was where are the moon, sun, and earth in relation to one another. We also talked about the position of the sun. Another thing that we had talked about and addressed in lab was about the different moon phases. I learned that the earth is in the middle of the solar system.
What did you learn in Thursday’s discussion?
In Thursday’s lecture we continued to learn and explore about the different moon phases. One thing that we learned was that the reason that we have and experience seasons is because of the earth’s tilt, and not because of how close the earth is to the sun. Another thing I learned was that the most important moon phases to know and remember are the full moon, quarter moon, new moon, and the other quarter moon. The way to figure out where the moon is based on the sun, is its always going to be opposite of the sun. So if the sun is setting the moon is rising.
Read the online textbook, chapter 5: https://pressbooks.uiowa.edu/methodsii/chapter/earth/
What did you learn?
One really interesting thing that I had learned was that the tropic lines, equator, and arctic circle are all different points on the earth that are specific areas of direct sunlight. I never knew this before and had thought that they were just randomly decided. Another term that I had learned from reading was equinox. I remember hearing this word before and learning about it, but I did not remember what exactly it meant and that this is when the earth receives an equal amount of sunlight for 12 hours.
What was most helpful?
Something that was most helpful within the pressbook reading was the different visuals and videos. In the reading it got a little confusing to picture and imagine in my head, but those visuals really helped me out with creating a mental picture. One specific diagram that was helpful was the solar eclipse diagram. This image helped me visualize the solar eclipse and helped me understand much better.It also helped me better understand the difference between the lunar and solar eclipse.
What do you need more information on?
One thing that I would like more information about is the tropic lines and the other specific lines on the earth. I learned a little bit about these from the article but would like to understand more about what exactly they are.
What questions, concerns, and/or comments do you have?
For the equator and tropic lines, are they only defined by receiving direct sunlight, or is there another purpose for them?
