Science 9:  After handing in the practice test we completed the Electricity Test.  Due next class is the DIY Electricity Cross Word.

Chemistry 11:  We completed Part I of Lab 20 C, and Calculations # 1-3 are due tomorrow.  Really well done!  

Science 10:  We began by going through pg 380 # 2-15, then we had a short discussion about the celestial sphere (altitude, azimuth, the ecliptic, Polaris).  We read pages 306 to 312 and completed pg 313 # 1-8 in quality point form.  Pg 313 is due tomorrow.

Science 8:  We spent some time discussing lenses, using our Mini Lens Lab as a guide.  Key terms to learn were converging, diverging, principal axis, focus, and focal distance.  We used convex lenses to magnify a random object, and found that the object has to be held closer to the lens than the focal distance.  After reading section 5.3, we completed pg 197 # 1-10.   In the last part of our class we went over the anatomy of any eye.
