1.) The big question addressed in lab, and a description of what you did.
We talked a lot about the Law of Superposition, and when the layers might have formed, and which ones came first, we also took the time to analyze some different sands, and calculate them as well.
2.) A description of what you learned in Thursday's lecture.
We talked about thinks floating and sinking, and then talked about geodes.
3.) Answer questions about the weekly textbook reading:
1.) What did you learn?
"A geode forms when a cavity forms in a rock, which can occur in different ways. One way a cavity can form occurs when a bubble of carbon dioxide and water vapor forms in flowing lava. As the molten rock cools and the gas dissolves, an empty space is left behind. Another possibility in which a cavity can form occurs when lava solidifies under water. Sometimes the outside of the melted rock cools before the inside, which becomes brittle and breaks a little bit due to the weight of the liquid inside."
2.) What was most helpful?
The videos/pictures.
3.) What do you need more information on?
