Week 6 - History of the Earth

Lab:

This week in lab we discussed the basics of astrology seeing what we all remembered about the Earth's orbit as well as how the seasons change and explaining the moons phases. It was interesting to see how little I remembered about these concepts as I feel like we talked about them so much from kindergarten to ninth grade, but after that point the learning switched to biology, chemistry, and physics ultimately affecting the retention of this knowledge.

Lecture:

In lecture, we went over the phases of the moon as well as how the seasons change making sure that we can lock the concept in before we move on. I really liked the models that were used in lecture when explaining the Earth's tilt as well as how the tilt affects where the tropic lines are at. We also talked about how the North Pole is always pointing to the North star, which is again something I didn't know. I also learned that it's possible to have 2 full moons in one month. I didn't know that was possible, but with the lunar cycle only being 28 days and months ranging from 28-31 days it makes sense how another cycle could get squeezed in.

Textbook: Sun, Earth, and the Moon

What I learned: In the reading I learned more about why the season's change and the science behind this. The Earth is always tilted on the same axis, but due to the tilt, different area's of Earth are tilted toward the sun at different times during the year. When a hemisphere is tilted toward the sun they are experiencing summer, and when they are tilted away from the sun, they are experiencing winter.

What was most helpful: The pictures after the explanations were very helpful for me as I'm more of a visual learner.

Week 10 - Earth's Structure

Lab In lab this week we worked to create different types of rocks including sedimentary, metamorphic, and igneous rocks. To do this, we used different colored starburst to represent different material being mixed together and used different methods to do so. The igneous rocks are hot and cool and some metamorphic rocks are created from heat but not melting, so we used both a candle and torch to mimic the heating of the rocks. For the sedimentary rocks we squished them together using different amounts of pressure to create the different types of rocks. We also used a bit of heat to cement the materials together.

Week 14 - Global Climate Change

Lab How does climate change work: Video How to fight with people about climate science More common events are more severe Need to understand the causes 2010-2020 hottest decade ever 2020- the largest number of mega fires Multi-year droughts leave a significant increase in the ignition of these fires Used to be more spread out, and now they’re annual Global average temperature has changed by 1 degree since the 80s What's driving this rise? Intensity of solar radiation Decomposition of Earth's atmosphere Some of the energy is absorbed into the ground, and the rest is reflected to the atmosphere and creates a blanket that warms the Earth CO2 is the most abundant gas in our atmosphere Alberto 1958 - 315 MMP Came to a peak and then came down again CO2 overall was rising Now is a better time than ever to make major changes For every million parts of air, there were 315 parts, but now, 421 parts are carbon dioxide.

Week 11 - Rocks and the Rock Cycle

Lab In lab we started by talking about the law of superposition... everyones fav! This law basically states that the older stuff is at the bottom and the longest is at the top. We used this to work to place different layers of rock in order from oldest to youngest based off different photos. Immediately, I was taken back to my ninth grade earth and space science class and I could remember doing exactly what we were doing in lab, but back in early high school... props to Ms. Howlett :) Then we moved into talking about different characteristics that sand from different places had. We looked closely at sand from beaches, dunes, and rivers around the world. Our group decided to look at each group and write down observations about each sample. All of the different rock types were from different areas and all had different colors, were different shapes, and just looked different. We came up with some characteristics for sand found in rivers, dunes, and beach's. River Sand Characte...
