Chemistry 11:  After working through 2 examples we did the Titrations Calculations WS.  Well done!  You will get some time to work on Lab 20C on Wednesday, and it will be due on Friday.   Reactions test on Monday.

Chemistry 11:  Today we took notes on Energy Changes in Chemical reactions, and did Unit 6 # 70 - 80 after reading pg 119 to 122.  We spent time working on Lab 20C, which will be due on the double block this week.  Our Reactions unit test will be on Monday.

Science 10:  Read pg 230 -233 and do pg 239 # 5,6,8,10,11 in fine sentences.

Science 10:  Today we took notes on Radioactive Decay.  We read pg 228 & 229, the completed the Radioactive Decay Equations WS.

Chemistry 11:  Lab 20 C is not due on Monday.  We will have a Chemical Reactions Test on Wednesday November 28, so be sure to be making you way through the stoichiometry exercises listed on the previous posts.

Chemistry 11:  I collected any remaining Lab 6A and 6Bs.  Today we titrated a solution of HCl to determine its unknown concentration.  Terrific work on your very first titration!  We spent time completing Lab 20C Questions and Calculations # 1-3, and working on the various Stoichiometry skill building exercises listed below.  These items need to be in your binder, ready to show me that you have been building your skills.

A)  Stoichiometry Involving Limiting Reactant (WS, white, key posted at the side)
B) Stoichiometry Calculations (WS, white, legal sized, key posted at the side)
C) Hebdon Unit 7 # 8 (answers in the back of your text)
D) Stoichiometry Calculations (WS, green, legal sized, key posted at the side table)

Science 10:  Today I collected any remaining Matching assignments and Lab 18E reports from Monday and Tuesday.  We read pg 234 to 238 and did pg 239 # 1-4,7,9 in fine sentences.  We reviewed atomic structure by making an atomic model on poster paper.  Everyone was assigned an isotope, except for one lucky student who was assigned Hydrogen-1, Hydrogen-2, and Hydrogen-3.  The instructions are written below in blue.

Create a mini poster showing the structure of an atom.  You will be assigned a particular atom of an element, called an isotope.

-show the placement and number of subatomic particles

-show a standard symbol for your isotope

-label the features on your standard symbol

-create a copy of Table 1 pg 156 (old Probe 10)

-have a large title, and put your name and date in the lower left corner

Science 10:  We started off with our last Balancing minipractice sheet, followed by Experiment #23 (Neutralization Reaction), which is due on Friday.  In the second half we learned about the workings of coal fired electricity production by watching this video, and we discussed the energy transformations involved.  We read pg 198 - 211 in our text, and got a start on pg 215 # 1-8, but this is not due.  I would rather you finished your Chemistry Practice test and spent some time preparing for our Chemistry test on Friday.

Chemistry 11:  After some practice balancing chemical reaction equations, we did the WS Titled Finding Limiting Reactant and Reactant in Excess.  In the second half we made a good start with Lab 6B, which is not due Friday.  There was time to work on Lab 6A, which is due on Friday.

Chemistry 11:  Today I collected the Predicting Products WS.  Unit 7 # 1-4 is due Friday.  We did the first part of Lab 6A, and will finish it on Friday.  We also started a WS called "finding the limiting reactant" and you will be given more time for this on Friday too.

Science 10:  I collected pg 175 at the start of the class.  We did Lab 8A, which included some work from a hand out and some analysis problems from pg 225 in the Old Science Probe 10.

Science 10:  Today we finished learning about Reaction Categories by reading pg 165 - 172 and taking brief notes on Neutralization and Combustion Reactions.  We did pg 175 # 1-5. 

Chemistry 11:  WS on Predicting Reaction Products, due on Wednesday.

Science 10:  We started off with a short lesson on Balancing, followed by the WS titled "Balancing WS II.  Time was given for pg 135 # 1-8 in sentences.  We took notes on Energy, and read section 18.1 and did pg 391  # 1-3 in the old Science Probe 9.  We finished with a short lab activity, where we did Double Replacment Reactions and predicted the products.


Wednesday, October 31

Chemistry 11:  After we wrote the Moles test, we reviewed how to balance chemical reaction equations.  Unit VI # 1-6 and any 20 from # 7-56 were assigned.

Science 10:  We started off with a short lesson on Balancing, followed by the WS titled "Balancing WS II.  Time was given for pg 135 # 1-8 in sentences.  We took notes on Energy, and read section 18.1 and did pg 391  # 1-3 in the old Science Probe 9.  We finished with a short lab activity, where we did Double Replacment Reactions and predicted the products.
