         <description><![CDATA[<div>1) Homework quiz on stoich - overall well done! Kahoot to review a bit, and mostly a work block. And a demo.<br><br>2) No new worksheets. Continue working on Unit 7 - Stoich (you do not need to work on titrations or percent yield, however feel free to). I now have full answers posted to that package. Work on limiting/excess questions on the other single page worksheet. I will post answers this weekend as the answers I printed were apparently wrong. (You could also just cover up those answers and do those questions?)<br><br>3) Not a formal homework quiz, but a review question to start off with - limiting/excess question.&nbsp;<br><br>Enjoy the weekend!<br><br><br></div>]]></description>

Just too many different phrases and I don't want you to be confused. I've made a worksheet that works with our method. <br><br>So don't do Hebden 14,15,16. Do questions 1-3 in the "spontaneity worksheet" posted instead. <br><br>I will also have copies in class tomorrow. </div>]]></description>

         <description><![CDATA[<div>Finishing up the unit - ended by reviewing equilibrium, spontaneity, etc. Looking looking at the factors that affect spontaneity and how that affects the position of equilibrium. <br><br>Homework: q1-3 on "equilibrium" worksheet. Answers are posted. <br><br>Next class: review for term test on Friday. <br><br>I had a request for a video summarizing the stuff we've been doing. This is the best I could find that doesn't go too in depth for determining spontaneity: <a href="https://www.youtube.com/watch?v=hNSD0YDsPsE">https://www.youtube.com/watch?v=hNSD0YDsPsE</a><br><br>This next video by the same guy discusses what we called "usable energy"  - he calls this "available energy", both better ways to describe it compared to "free energy". Going from high usable energy to low usable energy will be a negative change in that energy, which has the symbol G (for Gibbs free energy). He uses a lot of the same examples and ideas we did and introduces an equation you don't need to know, but it may be helpful that relates enthalpy and the system's entropy.... You can stop at 8:30 or so (or ignore the part about activation energy). Here's the link: <a href="https://www.youtube.com/watch?v=DPjMPeU5OeM">https://www.youtube.com/watch?v=DPjMPeU5OeM</a></div>]]></description>

For this quiz only, coming in to do corrections and writing and explanation for each answer you get wrong will earn you half a mark back. <br><br>Starting out electrochemistry unit with a demo of a voltaic cell. It worked! Brief intro notes to the unit describing what was happening and relating it to spontaneity. <br><br>No homework, other than reviewing what we went over in class.

         <description><![CDATA[<div>I've had a bunch of people coming in to ask why their term grade is different than what was showing on MyEd. I did not realize that if I don't make the grade visible, it isn't counted towards the total that you see. I hadn't yet made the grade from your term test visible because I was still deciding on how I would count it. The term mark includes that and I have since made it visible so everything should work out now. I decided to make the term test as a mark out of 9 instead of 8. Let me know if you have any questions.</div>]]></description>

         <description><![CDATA[<div>Finished up with titration curves. That's it for the unit and the year. <br><br>The unit test is next class during double blocks. Some more details and lots of practice questions are posted in the announcement. <br><br>I feel like class didn't end well and I'm really sorry if I didn't do enough to make you feel prepared for the test. We didn't have much of a choice but to continue on to finish up the last bit of content and I thought we had done a fair bit of review along the way. Maybe it wasn't enough. If you need help between now and the unit test, just come find me outside of class and I'm more than happy to help!</div>]]></description>

         <description><![CDATA[<div>I looked into this and yes, the deal is if it is like new condition (and I can sell it again as a new book) you can have the $25 back. <br><br>I have some cash that never got deposited, so the first few who come can get cash back. After that, it is a form, which I now have, to request a cheque to come directly from the account. <br><br>Come see me next week if you want to return it. If you found it helpful this year, you may want to keep it as a reference. You could also sell it privately if it isn't in good enough condition for me to give your deposit back. </div>]]></description>

         <description><![CDATA[<div>Grades for acid-base unit tests are posted. There are a few cases where students got grades drastically different from what I expected based on previous performance. Come talk to me within the next few days if you fall into that category and we’ll see what we can do about it!<br><br></div><div>Grades will be out next week and should be similar to what you see in your term grade currently. Final course grades will be the average of the 3 terms, per our course outline, however in some cases it may be higher for students who have shown continual improvements throughout the year. It won’t be lower!<br><br></div><div>Thanks to those who have already responded to the survey. It’s been really helpful to read – lots of different opinions on what we need more or less of in class, what helped and what didn’t. Plenty to think about for next year. One common thread has been that for at least this past term, class has been a bit monotonous. I think that’s entirely fair – I was tired and primarily concerned about getting through the material we needed to and kind of got stuck in a rut with lessons. Sorry that it wasn’t more engaging – definitely something I’ll work on for next year!<br><br></div><div>Please respond to the survey if you haven’t yet! I’ve removed the need for logging in, so if you weren’t able to get on before you should be able to access it now through the same link.<br><br></div><div>Thanks once again for being my students this year and putting up with me while I learn to do this whole teaching thing. I am really grateful that I get to start off my career at a school with such a friendly and kind student body. You’re just all such amazing people!<br><br></div><div>Have a fantastic summer everyone and happy graduation to grade 12s!!<br><br></div><div>(Block D and E – we technically have 1 more class. We’ll find something fun to do for those who show up! Marshmallows… maybe a demo or movie?)<br><br></div>]]></description>
