Week 9: Earthquakes and Volcanos

 Week 9: Earthquakes and Volcanos 

1. What did you do in lab today? In lab we made predictions on where earthquakes and volcanos happen on Earth. We then used a website to investigate where earthquakes and volcanos happen. I was able to notice some patterns where many earthquakes and volcanos happen they were on the edge of plate boundaries. A question I asked was why is there a volcano in Hawaii that erupts often in the middle of a plate boundary?

2. What was the big question? The big question for this weeks lab was what are the patterns where earthquakes and volcanos are. We used a website to explore this question within our groups. 

3. What did you learn in Thursdays lecture? In lecture I learned that Hawaii is a hot spot. The hot spot releases lava and then the tectonic plates shift creating the different islands of Hawaii. This is unique to specifically the Hawaiian Islands.

Textbook:

1. What did you learn? I learned that there are two different types of waves to determine whether an earthquake has occurred. P-waves have the ability to travel through any type of material. S-waves have the ability to ONLY travel through solid materials. Scientists measure these waves to determine the starting point of an earthquake plus the magnitude released.

2. What was the most helpful? I found the video on the formation of the Hawaiian Islands very interesting and helpful. As the pacific plate shifts west new islands in the chain were formed and are still being revealed. The youngest island is the Big Island of Hawaii and it is where the current hot spot is under.

3. What did you need more information on? The three ways volcanos can be formed are sort of confusing. I know there is convergent plates, divergent plates, and hot spots, but how deeply do we need to understand them?

1. What questions, comments, and/or concerns do you have? I feel that I didn't grasp an understanding of volcanos and earthquakes as a student in primary school. It is interesting to actually understand what is going on below the crust as I hear about these things happening around the world. Something I would like to learn more about is tsunamis. I was on the coast of Oregon this past summer while there was a tsunami watch from an earthquake in Russia.

Week 1: Earth Moon System

Week 1: Earth Moon System 1. What did you do in lab today? This week in lab we answered a handful of questions related to common misconceptions of how humans interpret the seasons, Moon, Earth, etc. We then got to model in groups how we thought the Moon and Earth rotated along with discussing how the Solar and Lunar Eclipse. 2. What was the big question? Three questions discussed in class along with my answers prior to whole class discussion: 1. How the phases of the moon occur? (The Moon covers the sun while it rotates around Earth.) 2. What causes the seasons? (The seasons are caused by how far away the Earth is from the Sun.)  3. What causes a lunar eclipse? (A line of the Sun, Moon, and Earth, but I'm unsure it what order.) 3. What did you learn in Thursday's discussion? I was not present in Thursday lecture due to an away volleyball game, but I did receive notes from Isabelle Sneath!  All the planets are on the same geometric plane, EXCEPT Pluto, therefore Pluto is not a ...

Week 4: Scale Model Solar System

 Week 4: Scale Model Solar System 1. What did you do in lab today? In lab we conducted an experiment to model the first four planets of our Solar System. We were able to use whatever was available to us in the classroom (lab space). The goal was to make it to scale in means of size and distance. My table group decided to start with our Sun being 500mm. From then on Mercury was 1.748mm, Venus was 4.349mm, Earth was 4.577mm, Mars was 2.428mm, and the Moon was 1.247mm. We ended up going from the science lab room down to the PLC at the West side of North Lindquist.  2. What was the big question? The big question presented at the beginning of lab was "Why is the sight of a full moon phases startling in the middle of the day?". A full moon during daylight happens when the moon and sun are positioned on opposite sides of the Earth. In this phase, the moon usually rises right as the sun sets and disappears as the sun comes up. This makes its presence during the day feel sort of out o...

Week 2: Space - The Final Frontier

Week 2: Space - The Final Frontier 1. What did you do in lab today? There was no lab as it was a holiday. 2. What was the big question? The four big questions we explored in lecture included how the moon was measured, who has gone to the moon, and what is the future of space travel. 3. What did you learn in Thursdays discussion? In lecture I learned that a  Greek astronomer Eratosthenes, 240 B.C.E found that the size of the Earth. He started with the knowledge that a circle is 360 degrees. He measured the angle of his shadow to be able to find the distance and multiply it by 50 and that is the length of the Earth. Ted talked about how y ou can easily do this in a classroom when you team up with other schools aka collaboration!! It allows students to see math and science in a real world context. Textbook: 1. What did you learn? I learned that James Van Allen created the radiation detecter that was in the Explorer 1 Satellite. His discovery of magnetic radiation belts around ou...
