Week 8

 

1. The big question addressed in lab, and a description of what you did.
1. This week in lab we all shared presentations about space. My group researched the topic of galaxies. During lab, we listened, observed, and participated in our classmate's presentations all about the main topics of space. From lab, I learned that nothing can escape a black hole and that there used to be a star bigger than the sun.
2. A description of what you learned in Thursday's lecture.
1. This week in lecture I learned that there is evidence as to why there was a bigger sun before ours existed. One piece of evidence is that our sun was formed from a bigger star that underwent a supernova. Our sun is made from the stellar nebula (dust and debris).
3. Answer questions about the weekly textbook reading:
   1. What did you learn?
   1. We are all made of stardust! Since elements like carbon, oxygen, and nitrogen make up the human body and Earth. These elements make up the cores of stars. When stars reach the end of their life cycle and explode in supernovae, they release these elements into space. These elements combined together to form new stars, plants, and life as we know it. Therefore, atoms in our bodies and elements on Earth trace back to being made of stardust. 
   2. What was most helpful?
   1. What I found most helpful from the reading was the video that explains why and how Earth was not made during the Big Bang. Instead, Earth was built from dust. These dust "bunnies" were heated, melted, and then cooled into solid pellets. The pellets are then collected together to make our planet. 
   3. What do you need more information on?
   1. I am still confused about the life cycle of Stars
