Chemistry 11:  We wrote the Atomic Theory Test today.  Finish the "Review of Molarity" WS from last week.

Science 8:  After a short review of seismology, we did Activity 13E where we used earthquake data to make predictions about the structures found under our Earth's crust.  No one has ever been there, or has drilled past a few km, so learning about the Earth's interior is challenging.  We measured from scale diagrams, converted to real distances, calculated speeds, and estimated the size of the liquid outer core.  In the final minutes we named all of the local peaks, and reviewed the rivers/streams/lakes between them.  Be sure to have enough paper, pencils and such to get you through the last 4 weeks of regular classes.
