Science 9:  Today we marked pg 85 together before handing it in.  We learned how the Carbon Cycle happens, and wrote a few brief notes on our Carbon Cycle Diagrams.  We worked from the old Science 10 Textbook, and we read section 4.2 and did pg 91 # 4-12, 16.  We finished with this short clip on the Carbon Cycle.  

Chemistry 12:  Today we made a Carbonate/Bicarbonate buffer and observed how it is good at resisting changes in pH.  We took a few notes on Buffers, then we read section 4.19 and did Unit 4 # 131-134.  The final minutes were spent on the Acid Base Practice Test - on Friday we will have a test on Unit 4.  Try to have your practice Test done for Thursday, then I can mark it.  

 

 Science 9:  Today we started with a short review, followed by this clip by the Ameoba Sisters about Biomolecules.  We created a table to show the biomolecules found in our favorite foods (a variety of foods, including one drink).    In the second half, we learned about Biomes by reading pgs 54 - 58 and filling in a placemat.  In each section record the yearly rainfall, main producer species, and 2 key facts about the biome.  We finished with this TED talk by Paul Nicklen about the Polar Ice Biome.  Only the Nutrition Fact Biomolecule table is due Friday, not the Biomes.

 Chemistry 12:  Today we started with a review of Hydrolysis, and the we learned how to calculate pH in solutions of weak bases.  Due Thursday is U4 # 85-89, and 70.  You were also given a minireview of Hydrolysis, see the key here.

84.  0.024 M SO₃^2-

85.  0.0019 M OH^-, pH 11.28, pOH 2.72, 5.3 x 10^-12 M H⁺

86.  0.059 M N₂H₄

87.  K_b = 1.04 x 10^-3

88. pH 11.50

89. K_b = 9.34 x 10^-7

Science 9:  Today we had Staci Klein here to do the last classroom portion of Farm to Table.

 Chemistry 12:  Today we did Unit 4 # 74-79, view the key here.  These are due Tuesday.  We also wrote a quiz on Hydrolysis in the last 10 minutes.

Science 9:  We added a little to our Food Chains and Webs Notes, then we read section 2.4 and did pg 37 # 1-12 (half in sentences).  Next day Staci Klein will come to do part 2 of the farm to table program.

 Friday, May 6th

Chemistry 12:  Today we took notes on Hydrolysis, read section 4.13, and completed # 69 & 71 in Unit 4.  Be sure to justify your responses with Bronsted-Lowry reaction equations and Ka and Kb calculations.  I collected Lab 20G today too.

Science 9:  After going through pg 29 # 2-12,14 in the old Science Probe 10 text, we viewed Williamson's lake pond water to look for phytoplankton, zooplankton, and invertebrates.  In aquatic environments, phytoplankton are the main producers, and the food chain goes up from there.  

 Science 9:  Today we took notes on Food Chains and Webs.  We read section 2.2 in the old Science Probe 10, and we did pg 29 # 2-12 in sentences where appropriate.  We created posters for the Farm to Table program, where we showed the complete product supply journey for one of these food items:  Steak, Garlic Bread, Salad, and Kale. 

 Tuesday, May 3rd

Chemistry 12:  Today we began with a review of pH and pOH, then we did the Mini Review for Section 4.11.  Click here to see the key.  Time was provided for Lab 20G, which is due Friday.  Ensure that past Hebdon Problems are complete:  U4 # 31-37 and  U4 # 50-57.

Science 9: Today I forgot to collect the Heat Lab.  We had a guest speaker today, Staci Klein from the Local Food Initiative.   We spoke about where our food comes from.   Because we are heterotrophs, we have to consume other creatures to obtain our nutrients.
