We went over the results from yesterday's 24 layer sandwich activity. A few groups created perfect sandwiches, and the rest of the groups were pretty close to getting correctly constructed sandwiches.
Next, we expanded our study of correlating rock layers and superposition through the use of trace fossils. This paper and pencil activity was started today, and will be continued in class tomorrow.
Tonight's Homework: Read pages 59 - 63 and answer the questions on page 63.
