Chemistry 11:  We began with a short lesson on dilutions, where we learned how to use the dilution equation (cf = ci (vi/vf)).  Normally, we like to solve problems from basic principles, but this tool is soooo handy. We did page 104 # 97 and 99 to try it out.  We then completed the Concentration of Ions WS.  Click here to see the key.  In the second half watched this clip to see liquid nitrogen, then we wrote notes about Intermolecular bonding.  After reading 9.3 we began # 8-16 but these are not due on Friday. Test on Atomic Theory and Solution Chemistry next week on the double block.

 Science 8:  We did another round of finding the epicenter, given three seismograms.  Due next class are Discussion Questions, # 1-5, written in fine sentences.  In the second half we did the Pangaea cut and paste, which is also due Friday.  We watched this clip, which does not explain continental drift, but is fun anyway.  We also looked at this animation that makes a guess at the positions of the continents in the past and future.   The last minutes were spent going through the local mountain peaks visible from the school.  Click on this google view to see most of those peaks (clockwise:  Begbie, MacPherson, Boulder, Kirkup, Copeland, Frisby, Revelstoke, Mackenzie, Cartier).  

Chemistry 12:  We began electrochem today, by looking at a chemical cell, reading 9.1, and completing unit 5 # 1,2.  I collected the practice test and marked the written part, then we went over the answer to the multiple choice.  We watched this clip about ocean acidification due CO2 absorbtion.  Next class we will complete the Acids and Bases unit test, and you can use your own databooklet with its helpful equations and notes.     

Chemistry 12:  After a short review of Buffers, we completed the Acids and Bases practice test.  The practice Test is due on Wednesday, and the Unit 4 test is on Friday.

Chemistry 11:  We made solutions with a partner, then we tested them for conductivity.  We took brief notes on Solutions, then we read section 9.1 and 9.2.  We started Unit 9 # 1, and 6-8, but these are not due Thursday.  The Dead Sea Lab was collected today.

Science 8:  After a review of continents, oceans, mountain ranges, and large islands, we learned how to find the epicentre of an earthquake.  We used seismographs from 5 different seismic stations to triangulate the epicentre location.  Due next class is a paragraph describing how to find an epicentre.   

Chemistry 12:  We reviewed finding pH given a strong acid, strong base, weak acid, and weak base.  Next was the Hydrolysis mini review WS.  After making a buffer (.20 M sodium carbonate with .20M sodium bicarbonate), we wrote brief notes then read 4.19.  We began U4 # 131 - 134, 136, 139, but this is not due yet.  Test on Unit 4 on Friday, so a little review each day will be helpful.

Chemistry 11:  On Lab 12B we wrote the geometry names and the bond angles to highlight common molecular structures:  tetrahedral, trigonal planar, linear, and trigonal pyramidal.  We then completed the Dead Sea lab, where everyone found the [NaCl] in a saturated salt solution.  This is due Tuesday.

Science 8:  We started with a review of continents, oceans, and large islands. We took brief notes on Seismology after talking about earthquake safety and viewing a number of short clips (one about Kobe, one about swimming pools, and one about seismographs).  With a partner, we practiced travelling like P and S waves, with the distance between the waves growing ever larger as the waves travel further.  We read section 11.3 from the old Probe 9, and we practiced drawing circles with compasses.  

Chemistry 11:  We went over the Lewis Dot Diagrams first, then completed procedure steps 1,2,4 for Lab 12B.  We looked at some element families (Alkali Metals, Alkaline Earth Metals, Halogens, and Noble Gases), and read about Mendeleev from Bill Bryon's "A Short History of Nearly Everything".  

Chemistry 12:  Kb Calculations today.  Due Monday are Unit 4 # 84 - 88, the Indicators WS, and the Hydrolysis WS.

Science 8 :  Optics and Waves test today. At the end we labelled a map with all the continents and all the oceans, to kick off our Geology Unit.  We colored all the countries we have been to in one color, then used a different color for 3 countries we would like to travel to when we are older.  

Thursday, December 5th.

Chemistry 12:  We started with the all topics Review WS (4.1 to 4.15).  Next we went right into Ka calculations:  we did # 75 and 78 together, then everyone completed 74-80 (all due next class).  In the second half we learned about Indicators, took brief notes, read 4.17, and completed Unit 4 # 108-118 - also due on Friday.  Some people began the Hydrolysis WS.

Science 8:  We went over the Optics Practice Test first, then spent a little time looking at the Science Department telescope.  After preparing Lab 6-2, we completed it (Sheep's Eye Dissection).  All of the Conclude and Apply and Analyze questions are due, in sentence format, for Friday.  Test on Friday.

Chemistry 11:  A short discussion about the Schulich Leadership Scholarship and careers resources started the day off.  CareerTrek Video series, EducationPlannerBC, SkilledTrades BC, and myBlueprint are excellent tools for researching different training programs and work possibilities.  We wrote brief notes on Covalent Bonding, then we read pages 176 - 179.  Due next class are Unit 8 # 51-72.  In the second half we learned how to create Lewis Dot Structures, and the DIY worksheet is due on Friday as well.   

Science 8:  After a review of numerous optics topics, we completed the Waves and Optics Practice Test, which is due on Thursday.  Test on Friday.

Chemistry 12:  We took brief notes on Hydrolysis, a process were salts can cause the formation of hydronium and/or hydroxide in water.   We read section 4.13 then completed # 69, 71, 72, and 68.  We finished with a quiz on partial neutralization reactions.  

Chemistry 11: We spoke about the rock cycle - rocks are largely mixtures of ionic compounds and so share the characteristics of ionic substances:  high melting point and brittle.  We took brief notes on Ionic Bonding, then we read pages 170 - 176 and completed Unit 8 # 53-67.  Quality point form has short phrases but no single words or numbers.  We finished by planning how to find the molar concentration of NaCl in saturated salt solution.
