Science 8:  We wrote notes on the Theory of Plate Tectonics, then we read pgs 505 to 507 in the Science Probe 10 textbook.  Due Monday is page 508 # 1-6 and 13.   Click here to see the assignment log.

Chemistry 11:  We learned how to write dissolving reaction equations, then we used the ratios to find the concentration of ions in solution.  Due Monday is the WS titled  "Calculating the Concentration of Ions".  We also made mini Dead Seas, and next week we will determine the concentration of NaCl in the saturated sodium chloride solution.  Click here to see the assignment log.

 Chemistry 11:  Today we did Lab 16A (Polar and Non-Polar Solutes and Solvents).  Do all of the Questions, but skip the Follow-up questions.  We also learned about diluting solutions, and started U5 # 78-82, 87, and 89.  Click here to see the assignment log.

Science 8:  We learned about continental drift, and created a model of Pangaea using fossil evidence to place the continents.    We read a short article about Wegener and his list of evidence for continental drift.  Of course, today we don't worry about his evidence too much because we can measure the positions of the continents carefully using modern technology.  We watched this clip to see an animation drifting continents.  In the second half we looked a map of our area of BC and labelled the towns, rivers, lakes, steams, mountains, and dams.   On the back is a crossword that can be completed too.

 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. 

 Chemistry 11:  After a short review of mountains, isotopes, and subatomic particles, we did the Atomic Theory Practice Test.  Click here to see the key.  The WS titled "Review of Molarity" is not due.  We will have test on Tuesday on Atomic Theory.

Science 8:  Today we used maps, compasses, and earthquake data to locate an epicenter location.  We also listed all of the rivers, lakes, and streams that could be accessed with a bike ride.  This is what we came up with: Columbia River, Illecillewaet River, Jordan River, Begbie Creek, Greeley Creek,  Tum Tum, Martha Creek, Bridge Creek,  Lake Revelstoke, Williamson's Lake, Montana Creek, Echo Lake, Eva Lake.

 Chemistry 11:  We began by reviewing Lab 12B, and we wrote names and bond angles onto some of the molecules (planar, tetrahedral, trigonal pyramidal, linear).  We also spoke about the difference between polar and non-polar objects, and applied this to molecules.  Examples of symmetrical and asymmetrical molecules were shown, using Hebdon's "string pulling" analogy.  After writing brief notes on Intermolecular bonding we read pages 179-181 and 198 - 202.  Due Friday is Unit 8 # 74-77 and Unit 9 # 10-12.  In the second half everyone was assigned a standard solution to make, using either sucrose, MgCl2, or MgSO4.  We took notes on solutions, and we began the "Review of Molarity" WS, but this is not due.  On Tuesday we will have a test on Atomic Theory.   Click here to see the Chem 11 Assignment Log.

 Science 8:  We began with a review of the continents and oceans, because we are doing the Geology Unit Last.  We took notes on Seismology, and we practiced being P and S waves by walking across the classroom with a partner, ensuring that the first person was about twice as fast as the second half.  We read from an old Science Probe 9 text about Earthquakes, and we did Activity 10E and 10F (all procedure, and discussion questions # 1-3).  In the second half we went to the track and paced out 100 m.  We created a table to calculate the steps needed for 10m, 1 km, 1000 km, and 40 000 km.  It was important that large numbers were written in batches of 3 digits (from the right end).  Commas are not used in Science numbers.  Like this:  "The world is about 40 000 000 m in circumference.".  Our last task was to find an epicenter for an earthquake.  We started with seismograms from 5 cities, and we measured the arrival time for P and S waves.  On Friday we will use a compass to triangulate the data and find the epicenter.  Wow, what a terrific class - you accomplished a lot!  Click here to see the assignment log.
