Week 6: Geological Time

 Week 6: Geological Time

1. What did we do in lab today? In lab this week we reviewed shadows, moon phases, stars, galaxies, etc for the exam. Something that I needed to work on remembering was the three types of galaxies: spiral, elliptical, and regular. Following the mini review session we did an activity with a timeline and where we thoughts events like dinosaurs roaming the Earth, creation of the Moon, and humans appearing happened. 

2. What was the big question? I felt like the question of the day was what are the significant events in the history of the Earth. There was a cool website that allowed us to identify important (and cool) events that happened in the range of a billion years. 

3. What did you learn in Thursdays lecture? No Lecture, Just Exam.

Textbook:

1. What did you learn? I learned what a geological time scale is and how scientist utilize it to describe the events that have happened on Earth. The time scale is almost like a clock and the various different colors are periods of time. 

2. What was most helpful? There was a key takeaway that simplified Earths big events into more so elementary school terms. This was helpful for me to understand as I'm unsure what the periods of time refer to.

3. What do you need more information on? I do not quite understand how people know what time periods refer to what event. For example Hadean is the formation of the Earth, but is that obvious without background knowledge.

1. What questions, comments, and/or concerns do you have? Are we going to be quizzed over the geological time scale?

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...
