This week we will begin studying sedimentary rocks and the process by which they are formed. Today students read about how sedimentary rocks are formed through the processes of physical and chemical weathering, cementation, compaction, and leaching of minerals through the rock. Students will have many hands on activities, models, and animations to illustrate the process. I will show students how vinegar chemically weathers chalk, or limestone. We will do a cementation and compaction activity to "create" various types of rocks with clay, sand, and Plaster of Paris. Finally, we will learn about the different environments in which sedimentary rock form and the most common types.
Monday: pg. 475 Review #2, 4, 5
Tuesday: Add images/pictures to the Sedimentary rock flow chart students already made in class. Students may draw or print out images. I suggest students go to google images and search for physical weathering, chemical weathering, cementation, leaching, and compaction. If students do not have a printer at home, drawing the images is acceptable.
Wednesday: Pg. 475 Reflect #4, 5, 6
Thursday: Pg. 475 Review #1, Reflect #1-3
