The big question addressed in lab, and a description of what you did. In lab, we started out by being shown a picture of rocks and had to determine what rocks came first. We worked through that picture as a class. The rocks follow the law of superposition, which means that the rocks at the bottom are the oldest and the rocks at the top are the youngest. We then focused on sand and looking at them through a microscope. It was interesting because all of the sand was different from each other. We were able to place the sand in the communities that they belonged. To conclude class, we discussed Archimedes principle and water displacement and looked at Geodes to try and see which geodes would be hallow inside and which geodes would be solid inside. A description of what you learned in Thursday's lecture. In lecture we discussed more in detail about the rock cycle. We also went into detail about erosion --> wind erosion, water erosion, and glacier erosion. We finished class by drawing...
