Methods II- Week 8
1.) The big question addressed in lab, and a description of what you did.
We spent the class time on Monday going over the different presentations that were assigned in class. My group chose to do the lifecycle of the stars.
2.) A description of what you learned in Thursday's lecture.
We talked about so many different things, some were that of how the earth got its start, how the moon got here, and how we came to be. We asked things like when were the first humans here. There was a a bunch of things wrapped into one.
- Stars and Galaxies began to form about 12.7 billion years ago.
- Our star (SUN) formed from a stellar nebula (dust and debris) most likely from a star that underwent a supernova.
- Ours is 4.65 billion years old and is about half-way through its full supply.
- Red giants burn fuel and lose mass, therefore increasing is size due to less mass.
- Nuclear fusion – stars can make up to IRON (Fe) on the periodic table of elements.
3.) Answer questions about the weekly textbook reading:
1.) What did you learn?
I leaned just about how long ago the Earth and parts of our solar system were created.
2.) What was most helpful?
The videos and scale diagrams to show the creation and the length of the solar system.
