Science 8:  We began with a short review of the layers of the Earth.  We then drew 3 circles with compasses, measured the radius and diameter, and made a table to show our data.  We learned how P waves arrive before S waves when a location experiences an earthquake, and if the epicenter is far away the time interval between the S and P waves will be large.  This can be used to find the location of the Epicenter.  Using the data on this hand-out, locate the Epicenter on the map.   This video explains the technique partially, and it is clearly explained.  This video is more detailed. 

Chemistry 11:  We learned how to name and draw structures for Alkyl Halides (organic molecules containing F, Cl, Br, or I atoms). We read section 10.3 and completed # 17-19, sketching every molecule.  These questions, as well as the Dead Sea Lab, is due on Monday.  We completed a practice quiz at the end. 

Chemistry 12:  After a short review (Mini Review 5.1 to 5.4,) we learned how to balance full redox equations using the half cell method.   Due Monday is Unit 5 # 24 (any 4 acidic and any 4 basic reactions only).
