Chemistry 11

Today we looked at how to calculate the concentration of ions in solution and how to write dissociation equations.

Due on Friday:  Concentration Assignment   
Friday Quiz on concentration calculations

Thursday we will write the TRU chemistry contest

Biology 12

Today we went over internal and external respiration.  How does oxygen get into your blood?  How does it leave the blood and get into the tissues?

Module Questions:  E, F and G for homework. 

Biology 12

Today we went over the mechanics of breathing and looked at how the change in lung volume causes air to move in and out of your lungs.

We completed an inhalation and exhalation worksheet in class

Homework:  Complete external and internal respiration worksheet (yellow sheet) as well as module questions A-C. 

Chemistry 11

Today we looked continued our notes on solutions.  Be able to do calculations to find moles, Molarity or volume (L).

Next we studied dilution calculations.  What happens when you want to dilute a stock solution or what is the new concentration after dilution?   We diluted our stock solutions of potassium permanganate with new volumetric flasks.

Hebden:  pg. 98 Ex:  59 (a-c)  60 (a-c) and 62
pg. 102  Ex: 78-81

Biology 12

We wrote the circulatory system test today.   Be still my heart! 

Keep working on the respiratory system by doing module questions A(#1) B(all) and C(all)

These module questions are due on Tuesday.

Chemistry 11

I collected lab 12A with a conclusion

We started Unit 6 today.    Now we get to study Solution Chemistry which is less theory and more doing!

We took notes on solutions/solutes/concentration etc.

Finally we learned how to make a standard solution using a volumetric flask.   No homework!

Biology 12

Today we reviewed some of the concepts in the circulatory system, measured our heart beats, our blood pressure and listened to our hearts.

We started off the respiratory system by doing a short labelling/diagram assignment
