In lab this week we played Kahoot to prepare for the exam. Some notes I too: young river- lots of energy young river creates V-shaped valley 1/4 of 2.7 25% full  earth melted from ocean volcanoes and co2  the climate is a 30 yr average of weather.  Some analogies to remember that: weather what clothes u wear, climate what clothes you buy weather is a song, climate is a playlist  weather is a shred of carrot, climate is the salad. We also did a little review on the film "Before the Flood" We then did an activity to figure out precipitation change in Iowa over the last 100 years  As climate change gets worse there will be more pandemics. A description of what you learned in Thursday's lecture. In lecture we took our earth science exam.  Answer questions about the weekly textbook reading: What did you learn?/ What was most helpful? In place of reading, I took practice quizzes to prepare for the test.  What do you need more information on?  The albedo...

The big question addressed in lab, and a description of what you did. In lab, we talked about a lot of different types of rocks, crystals, superposition, erosion, and weathering. Firstly, we talked about geodes and how a full geode has a density of 2.7. if the density is more than 2.7 it is not a geode. If the geode is less than 2.7 than it is whatever its density divided by 2.7 full. For example, a geode with a density of 1.3 is about half full. Whenever geodes are brought up I automatically think of two things one the above picture of a grotto that is back home at St. Mary's in West Burlington, across the street from one of my childhood homes. The second is United States Gypsum a mining company where my dad works that mines gypsum which is a mineral found in crystals like geodes. They mine it mainly to make sheetrock. Next, we reviewed the homework 'Sweater Weather' and  road cuts. Example: back home in Sperry, Iowa my first childhood home is on a road named Stony Hollow....
