Science 9: Today I collected permission forms for Thursday's fieldtrip to the Water Treatment Plant and the Sewage Treatment Plant. We did our Ecology Unit Test today.
Chemistry 12: We started with a mini review of sections 5.1 to 5.4, then we took notes on Electrochemical Cells. We read both sections 5.8 and 5.9, and completed 34-37.
Science 9: View the Practice Test here, and the key here. Click here to see the page 4 key. Due Monday is your permission form for our Greeley Trip as well as your practice test. On Monday, we will have a test on everything we have learned since Ms. Busch left.
Chemistry 12: Today we learned how to balance full electrochemical cells. Due Monday is Unit 5 # 24 (choose 9, ensuring that 4 are basic and 1 is a disproportionation reaction).
Chemistry 12: The Oxidation Number WS was collected today. We began with a short discussion about spontenaiety, and we learned how to use our databooklet to determine if a reaction will occur, or not. We read section 4.3, and completed # 7-14. A Mini review WS was given out after that. In the second half we learned how to balance half cells, and we completed any 10 problems from Unit 5 # 19
Science 9: On Wednesday, we did pg 100 # 1-15 from the old Science Probe 10, which will be due on Friday. We also learned about Scientific Notation, and began a short lab where we calculated the carbon stored in a tree. We will have a Test on Biogeochemical Cycling on Monday, and a field trip on Thursday to the water treatment and sewage treatment plant.
Science 9: We handed in the Bar Graphs today that showed the Carbon storage for each biome. We took notes on the Nitrogen Cycle, read section 4.3 in the old Probe 10 textbook, and completed pg 95 # 2-10, 15, and 17 (Due Wednesday).
Chemistry 12: We started off the Electrochemistry Unit by constructing a Copper half cell and a Zinc Half Cell, and connecting them to make a cell that produced nearly 1 V. We read 5.1 and completed # 1,2. In the second half we learned how to do oxidation number, which is a technique that is useful in determining which species are oxidized and which are reduced. The Oxidation number WS is due Thursday.
Science 9: Today learned about the Carbon stored in soil. We watched this clip about decomposing pumpkin to observe the bioturbation that occurred and to help us consider the components of soil (water, detritius, rock fragments, bacteria, fungi, and invertebrates. We also watched this clip to help us visualize the decrease in volume of biomass, to help us reason that CO2 is leaving a compost pile. We made a bar graph using this data to show Carbon Storage vs Biome.
Chemistry 12: Today we wrote our Acids and Bases Unit Test. Well done! No homework in Chemistry 12 this weekend.
Chemistry 12: We started with a mini review of Buffers, then we took notes on Metal and Non-metal oxides. We finished the Practice Test, which is due by Friday. This TED Talk by Triona McGrath explains why Ocean water pH has dropped in past few decades. We have an Acids and Bases test on Friday, tomorrow.
Science 9: We began with a survey of local tree species, and you made a guide to help people identify cedars, yews, firs, pines, spruces, maples, mountain ash, and birch. We spent time learning about 5 carbon sinks: biomass, fossil fuels, atmosphere, ocean water, and limestone in the Earth's crust. We finished by reading "The Largest Migration on Earth", an article about carbon cycling within the ocean. Click here to learn about salps. At the end of the class, I collected pg 91 that was assigned on Tuesday.
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 SO32-
85. 0.0019 M OH-, pH 11.28, pOH 2.72, 5.3 x 10-12 M H+
86. 0.059 M N2H4
87. Kb = 1.04 x 10-3
88. pH 11.50
89. Kb = 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.
