In lab, we met Ted and we did a lot of unlearning of some misconceptions (dramatized elipses, what causes seasons, etc.) We did this as a pre-test in lab too (I believe this was the big concept in lab):
1. How do the phases of the moon occur? The phases of the moon occur when the Earth blocks part of the light that the Sun shines on the moon. It can be waxing or waning, depending on how much Sun that the Earth is blocking.
2. What causes the seasons?
The seasons are caused by the Earth being tilted causing the hemispheres being closer or further away from the Sun.
3. What causes a lunar eclipse?
The Earth completely blocking out the light from the Sun on the moon causes it to look like no moon and a lunar eclipse.
In lecture we did another short pre-test and learned how to use our arms/hands to map out the moon in relation to the sun. It took a lot for me to focus on how the moon's orbit changed in relation to the Earth's orbit and how they line up during certain parts of the month. It's hard to unlearn all these misconceptions, but Ted was very helpful in demonstrating and reteaching us how the orbit actually works.
Answer questions about the weekly textbook reading:
- What did you learn?
I learned about the difference between heliocentrism and geocentrism, and the history about it.
- What was most helpful?
The most helpful part of the reading was the diagram that shows the moon and how the light always comes from the sun side but how it looks different on earth. It's hard to conceptualize that half of the moon is always lit but we can only see parts of it, so the diagram is helpful.
- What do you need more information on?
I would like to know when the next total solar eclipse is. During the last one (I think it was 2016 or 2017) I went to go see it with my friends and I even had some friends that went to Missouri in the line of totality and I think it would be really cool to go see it.
- What questions/concerns/comments do you have?
Just when the next total solar eclipse is.
