End of year survey

Please take some time to thoughtfully reply to the end of the year survey.  This will provide feedback that should help me improve the course next year.  Thank you.

End of year survey

Qualitative Analysis and Final Exam Unit 9

For the last few weeks of school we will be working on qualitative analysis of unknown solutions.  This extended lab will summarize many of the reaction types we have studied this year and will increase student analytical skills.

The final exam will be comprehensive.  Students should review all notes from the year, study chapter reviews and complete a practice exam during the last days before the final exam.

Equilibrium Unit 7

This unit is on equilibrium.  In chapter 12 study section 12-3 only p. 372 to 382.  Complete chapter 12 review problems 8 to 15 all.  In chapter 18 study the whole chapter p. 553 to 584 except skip section 18-3 and complete 1 to 37 odd review problems.  There will be a test on equilibrium on 4/30.

 In addition to study of the text and your class notes you should consider the internet, especially YouTube chemistry channels, an essential part of learning chemistry well.  WATCH THE VIDEOS... you will slowly build important concepts...

Stoichiometry Unit 5

This unit is on stoichiometry.  You will be studying chemical formulas, reactions, equations and the mole concept. There will also be some work done learning mass and gaseous volume relationships; the ideal gas equation. Chapter 8 complete questions 1 to 35 odd.  Chapter 9 complete questions 1 to 29 odd.  There are many online videos that can help you learn stoichiometry.  Outside of what we learn in class, I suggest using khan academy or brightstorm to 'pick it up the first time' and reviewing with the IB style thornley videos or crashcourse... see links below.  Continue to work on memorizing ions from the previous unit if you have not learned them all yet. You will use them throughout the rest of the year. Keep memorizing ions!  Test on 2/26

 In addition to study of the text and your class notes you should consider the internet, especially YouTube chemistry channels, an essential part of learning chemistry well.  WATCH THE VIDEOS... you will slowly build important concepts...

Students who are not prepared in math skills are the students who struggle the most and have to spend the most time on chemistry.  If you are not concurrently enrolled in algebra 3-4 or above you may not really have the prerequisite math ability for chemistry.  Students in geometry will need to spend more time on problem solving parts of chemistry, especially in the second semester, to keep up.
