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.

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.

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

Chemistry 11

Today we wrote our test on Atoms and the Periodic Table........are you happy that we won't be talking about ionization energy again for a while??

We completed lab 12A by looking at melting times for each of our compounds:

NaNO3 = long melting time
MgCl2 * 6H20 = long melting time
C6H12O6 = short melting time
C12H22O11 = short melting time
KI = long melting time

This lab is due on Friday with Questions #1-3 and Follow-up #1 and Conclusion
