 Science 8:  We viewed samples of elements, and for each we wrote the name, symbol, and physical properties in a tidy table.  We also categorized each as a metal or non-metal.  This clip showed how aluminum is made, like what happens in Kitimat BC.   In the second half we wrote notes on our Temperatue vs Time graph for heating water.  This type of graph is called a heating curve.  A second heating curve was constructed with data for a mystery substance.  This allowed us to determine if the substance was butter, margarine, gold, or yellow plastic.   In the final half hour we wrote notes on atomic structure.  We did pg 156 # 2 in the old Science Probe 10.  

Science 9:  I collected the practice test today, marked it, and handed it back before you left. Use your mistakes to improve your skills and knowledge before tomorrow, the  day of our test.  We spent time on electrostatics in the first half, performing a lab to look at attraction and repulsion.  We read pgs 202 to 207, then started pg 209 # 1-5 in sentences, but this is not due Friday.  In the final hour we made a human karyotype from a photograph of 46 chromosomes, cut and paste style.  No work needs to be completed for this for tomorrow.  Instead, spend some time reviewing everything we have done that is not Chemistry content.  You will be allowed to have your meiosis diagram on your desk tomorrow during your test (It can only have a labelled diagram of meiosis on it, no extras please).

 Science 10:  Today we learned about the Law of Conservation of Energy after a short review of energy topics.  We read a short section from a different textbook from a hand out, and completed Questions 1-5 to demonstrate our understanding.  In the final minutes we learned a little basic information about nuclear energy.   This animation shows nuclear fission reactions quite clearly.   We will watch this video on Friday.  

Chemistry 11: In the first half we reviewed skills with solutions (calcuations involving moles, volume, and concentration.  Due Friday is Unit 5 # 61-66.  We learned how to make a standard solution, then everyone made a standard solution with their partner.  A lab report was written with the following sections:  Title, Purpose, Materials, and Procedure.  We started a worksheet on empirical formula, but this is not due Friday.  We finished with a quiz on moles skills.

Science 10:  We took notes on speed and kinetic energy, then we complete this WS to practice our skills.  The WS is due Monday.   In the last 25 minutes we went through a short intro on Nuclear energy, the energy stored in the nucleus of an atom.  We looked at this animation of radioactivity called alpha decay.  We also reviewed atomic structure, with a particular focus on the contents of the nucleus (protons and neutrons). 

Science 9:  We added a few notes to our Meiosis diagrams, then we reviewed human male and female reproductive anatomy.   We watched this clip on human pregnancy, then we read pgs 52-56 and completed pg 57 # 1-6 in sentences.

Science 8:  We wrote a results and conclusion section for the Density Lab, then the lab was handed in.  We read pages 260 - 263 and completed Activity 7-6 (Dense, Denser, Densest) in sentence format.  This clip is about gold, which is very dense.   In the final minutes, we determined the density of irregular mineral samples (feldspar and galena) using displacement to find the volume.  Special care was taken to record data in a clear way and show clear calculations to find the density.   More time will be given for the irregular objects on Monday.

Science 9:  We added a little to our notes on the Cell cycle, then we prepared a placemat to learn about Asexual Reproduction (general info, Binary Fission, Budding).  We read pgs 22-29, then we wrote brief notes and sketches on or placemats.  We finished with a population activity:  If 100 cells of harmful E.coli bacteria are eaten by someone at 6:00, how many cells will be in their intestines at 10:00 pm of the cells divide every 10 minutes?  We used a two column table (Time & Population) to show our reasoning.

Science 8:  We reviewed first going through these lists, and recalling with our partner a word that would complete the lists.  We then identified the list.  The Chapter 1-3 practice test was completed next, and it si due on Monday.  We finished off by practicing measuring volume and mass. 

Science 10:  We started with the Chemistry Unit Test, then we made a graph of Temperature vs Time for our Heat Lab, part B (radiation). Click here to see the data.
