Chemistry 11

Today we practiced electron configurations for atoms and ions and used electron configurations to determine valence electrons.   Quiz on Tuesday!

Next we did a GIANT graphing assignment on trends in the periodic table.  You should have three graphs plotting the atomic radius, electronegativity and ionization.  You WILL have time to work on this on Monday.

Today we looked at electron configuration in atoms and learned why the Bohr Model isn't actually the "real" model of the atom.   It does give us some important information though about how electrons can gain or lose electrons to form stable configurations.

Homework:  Hebden: 1) pg.  149      the whole table needs to be done for tomorrow.
 2) pg. 150 Ex: 23 a, c, e and f

We wrote the stoichiometry test today.  Good Work!   There were some tough questions on there, some of which will be bonus marks.

1) Next we completed lab:  6D.  Answer all questions (not the follow-up) and write a conclusion.   In your conclusion remember to link back to the objectives and list sources of error.

2)  Read page 139-141 in Hebden.  Do exercises #1-4 and #6 pg. 142

Both of these are due tomorrow.  

Biology 12

Today we took notes on the enzymes involved in Chemical Digestion.

Digestion worksheet due tomorrow.

Also due on Wednesday is the lab:  Effect of Temperature on Enzymes.  No introduction required, but you do need to answer all questions and write a conclusion.

On Wednesday we will do the Fetal Pig Dissection.   Here are some good you tube videos demonstrating how:
