1. The big question addressed in lab, and a description of what you did. 
1. The big question we addressed in the lab was identifying sand and its textures based on what we see through the microscope. We then went on to look at around 10 jars of sand under the microscope and looked at either sand created through water, glaciers, or wind.
2. A description of what you learned in Thursday's lecture.
3. Answer questions about the weekly textbook reading:
1. What did you learn? 
1. This week's textbook reading taught me about rocks and the rock cycle. I learned about a geode. A geode is a hollow rock that is typically lined with crystals on the inside. Geodes are formed in sedimentary and volcanic rocks when mineral-rich water seeps into a cavity and deposits minerals over time. When we cut open the geode in class today, we learned that the outer layer of a geode is made of harder rock, and the inner cavity is filled with crystals like quartz, amethyst, or calcite. 
2. What was most helpful?
1. The most helpful part of today's lecture was when Ted demonstrated the sodas in the aquarium before us. It was more interactive, and I learned much more than when I was talking the entire time. 
3. What do you need more information on?
1. I need more information on how to read those graphs of the different rocks we looked at in the lab. It was very confusing to me.
4. What questions/concerns/comments do you have?
1. none
