Biology 12

Today we:
1) Turned in Introduction to the Nephron worksheet
2) Completed another fun colouring of the nephron worksheet and went over what gets secreted and reabsorbed at each step.
3) Took notes on hormone regulation of water balance
4) Watched a short video on what it's like to have kidney dialysis

Chemistry 11

Today we finished off our solutions unit.  I collected the Precipitations and Neutralizations Reactions worksheet.   Next we did Lab 20C:  Acid-Base Titration.   The goal was to get the lightest pink solution possible.     The lab is due on Friday with all Calculations. 

Biology 12

Today we finished off the respiratory system.   Respiratory Review Worksheet is Due on Wednesday. 

Module Questions H should be turned in if you haven't yet. 

Chemistry 11

Finish solutions unit today with a review of total ionic, net ionic equations and finding precipitate (from Friday).   This is not in Hebden----really part of Chemistry 12.   Worksheet on Precipitation Reactions and Neutralization reactions is due on Thursday. 

Chemistry 11

Today we wrote our quiz on Concentrations/Molarity and turned in the Concentration Assignment

Next we took notes on Conductivity of Aqueous Solutions and Precipitation Reactions

Next we did a very mini lab on solubility.  We wrote the molecular, total ionic and net ionic equations for the reaction of Lead (II) nitrate and sodium iodide.

Homework:  Hebden pg. 212 Ex: 30-35

Chemistry 11

Today we did the TRU chem contest........challenging!

Next we had some time to work on the Concentration Assignment followed by a short movie on elements in the periodic table.

Selected answers to the Concentration Assignment below:   (make sure you show all your work!)

1) 0.315 M         2) 285 mL     3d) 0.0447 moles of Fe⁺³   
                                                                    0.067 moles of SO₄^-2

4d) (NH₄)₂S ------- 2NH₄⁺  +   S^-2

6) [Cl^-] = 0.160 M             7) Final concentration of Na₂S = 0.72 M

9) When you mix the two solutions together, you must first find the NEW concentration of solution 1 and solutions 2 and then add them together Total LiF after mixing = 0.394 M 

10)  [Cl]=0.774 M

 

 

Biology 12

We took a short quiz on the respiratory system today followed by the FINAL fetal pig dissection.   We saw that the pigs lungs had 4 lobes on the left and three on the right hand side.

Next block we answered some cystic fibrosis questions and then watched the movie:  65 red roses.

You should have turned in the pig dissection questions as well as the cystic fibrosis questions
