What did you do in the lab? In our lab section, we discussed how we assess our students and what it actually means to give a student an A. We also discussed how the curve would be determined for our recent exam. We discussed grade inflation and how grades have been increasing since the 1960s. We went over all of the answers to our exam as well. We later talked about how the Earth has multiple layers and how tectonic plates move. For our main activity, we melted and melded starbursts together to see the different rock formations that were created on our Earth. The three different types of rocks that we covered in our class were igneous, sedimentary, and metamorphic rocks.  The big question in the lab? - Rock Formations  What did you talk about in the discussion? - In our lecture, we went into further detail about rock formations. We talked about the cycle of rock formations and how all rocks start from magma, and when magma is cooled, it forms igneous rocks, and from igneous ro...

 1. What did you learn in lab this week? - In our lab section this week, we talked about the timing of when things happened on Earth. We looked at a timeline that started with the creation of our universe or the "Big Bang," and it ended up where we are today. We started off by guessing where we thought some important historical things happened on the timeline, like dinosaurs, human creation, plant creation, etc. Then we realized that our predictions were way off because it has been a lot more time than we actually think. In our table groups, we looked at the Earthviewer website and checked when historical things like the ice age and the creation of oxygen actually happened, and then we calculated them to fit on our smaller-scaled timeline. My group found out when exactly oxygen was introduced onto Earth, and another big one was when the Earth was a snowball. We then went into a further discussion about how the Earth melted from that stage of its lifetime.  2. What was the big...

 What did you learn in lab this week? - In our lab section this week, we talked about more information on a variety of things involving space through class presentations. For the origin of the universe, we learned that many people believe in one of the three theories of how the universe was created. Those three theories are the Steady State Theory, the Big Bang Theory, and the Eternal Inflation Theory. In our stars presentation, we learned that a star's life depends on its mass. This means that the larger the mass, the shorter the life of the star. In the Galaxies presentation, we learned that most large galaxies have massive black holes at their centers, which can be billions of times the mass of the sun. Also, you can only see .0004% of our galaxy. What we learned in the Origin of the Earth presentation is after a massive star went through its lifespan and exploded, our sun and planets were made, so the Earth was born. What we learned about black holes is that black holes are hug...
