Chemistry 11:  We drew structural diagrams for all our Lewis Dot Diagrams from Monday, then we read about Covalent Bonding (page 176-179) and completed Unit 8 # 68-72( Due Friday).  Lab 12B (only procedure steps 1,2,4) was finished next, and then wrote brief notes on Ionic Bonding.  We read page 170-176, and started Unit 8 # 53-67 but this is not due on Friday. 

Science 8:  Page 189 # 1-9 was marked before it was handed in.   This short clip shows how large, accurate concave mirrors are constructed to make large telescopes.  We used convex lenses to cast an image of Dr. Dufensmirtch onto a screen, and found the image to be upright, small, and real.  With our partner we measured the focal length of the lens.  We read pages 190 to 193 and completed page 197 # 1-10 (in sentences).  In the second half we completed the procedure for Lab 5-8, then we labelled a human eye anatomy diagram.
