ASSESSMENT:

There are four summative assessment items in year 12. The two assessment items in Unit 3 are a Data Test (10%) and Student Experiment (20%). The two assessment items in Unit 4 are a Student Research Investigation (20%) and external Examination (50%). There is approximately one assessment item per term, although the yr 12 course is not aligned with school terms.



UNIT 3

Unit 3 Learning Goals and Success Criteria

Calendar. This is for the Unit 3 and 4 course with QLD holidays and weekends shaded. Print it out and write in ALL your assessment dates from ALL subjects. In A4 and 2 pages so glue together to make a single calendar. I can resize to A3 ideally so it is A2 size when glued together. Ask me in class if you want this.

1. Redox Reactions
Unit 3 Topic 2 (Yr 11 Week 34,35 6 lessons)

Introduction to REDOX notes - a one pager with some intro notes. Edited from CK-12

Introduction to REDOX Practice - Some questions on this topic. From CK-12

SC2 - will be covered by class discussion and some notes from the board. It is very much about applying an understanding of electronegativity to oxidation and reduction. This application of your understanding will play a part to "make predictions" in SC6.

NOTE: The use of the terms Oxidation number and Oxidation state are used formally in SC5 for this unit. In many texts they are interchangable, however it is worth kowing the difference. Read the second paragraph of this article to recognise the difference. This will be important in answering questions (in the exam) using the correct format.

Assigning Oxidation states's notes

Assigning Oxidation state practice - Some questions on this topic

Revision to this point. A one pager, should not be hard. Use to diagose any difficulty you are having.

Assigning Oxidation states - 13.5 mins, by Tyler DeWitt. Slow, methodical, great.

Oxidising and Reducing Agents - 15 mins, by Tyler DeWitt. Watch and learn

Balancing REDOX 1/2 Rn method - balancing by the half-reaction method, acidic environment only. Mainly an example of how to do it.

QUESTIONS Scroll down to the third set of examples ("balancing by the ion-electron method"), Click on any example, then "submit", and the solution is set out for you. AMAZING!

Balancing REDOX reactions in acidic solutions - 15 mins, by Tyler DeWitt. Click here to see him do a practice problem. A more difficult question for advanced users is here

Balancing REDOX practice - a CK-12 Sheet with some practice questions.

Review for this unit. From CK-12. 25 Q's.


2. Electrochemical cells
Unit 3 Topic 2 (Yr 11 Week 36 1 lesson)

NOTE: There is only one SC for this topic and it is a broad introduction to the idea of the link between chamcal energy and electrical energy in REDOX reactions and a few of the key terms.

Electrochemistry and Electrochemical cells notes A simple two pager (reduce when photocopying) with an intro to electrochemical cells


3. Galvanic cells
Unit 3 Topic 2 (Yr 11 Week 36,37 5 lessons)

Galvanic cells notes - covers the basic theory of this topic. Heavily edited from CK-12. You need to be able to do the questions on the third page.

Galvanic (Voltaic) cells - by Tyler again, 24 mins. Take your time, it is comprehensive, and simple.

Galvanic Cells - link to socratic site. Has text and a short 1.5 min video. Brief but also good.

Galvanic cell practice - edited from CK-12

Tutorial and simulation of Galvanic cell experiment - unbelieveable detail. On the left is a menu you can use to navigate. Work thru steps 1 and 2. Step 3 is the next topic.


4. Standard Electrode Potentials & Electrolytic cells
Unit 3 Topic 2 (Yr 11 Week 38 3 lessons)

Electric Potential - notes. Edited from CK- 12. A brief introduction to the idea of electric potential

Electric Potential - practice. Again an edited version of CK-12 questions. You should have no problems with these, checking for understanding.

Standard Reduction Potentials - notes A 3 pager, heavily edited version of some CK-12 notes here.

Galvanic cells worksheet with answers

Galvanic cells worksheet. Stolen from somewhere, no answers

SUMMARY of REDOX so far. Not certain about this sheet, but may be useful to check you know all the summary on here. Has a question at the end you should be able to do!

Electrolysis - notes. This is some of my writing and some borrowed stuff from CK-12. Has some questions at the end.


5. Chemical Equilibrium
Unit 3 Topic 1 (Yr 12 Week 1 3 lessons)

Start with the videos as introduction. The notes below cover most of the Success Criteria for this topic, but SC 19 and 24 will be done with classroom discussion/notes.

Open, closed, isolated systems. Definitions and simple explanations. We need only the first two definitions for this course, but knowing an isolated definition is good for thermodynamics.

Equilibrium by Crash course Covers reversibility at the start (stop at 4 mins 14 sec). Le Chatelier is introduced after this, more suited to next topic.

Introduction to Equilibrium (notes and practice). A 3 pager - some from CK-12, mostly rewritten. Last page has some graphs for students to sketch (checking for understanding)

Introduction to reversible reactions. nice and simple explaination of the idea. Nothing complicated.


6. Factors that affect Equilibrium
Unit 3 Topic 1 (Yr 12 Week 2 3 lessons)

The notes below cover this topic very well, except that there is no mention of collision theory (SC 26) or the effect on Keq (SC27). These two points will be additions to the notes during class discussion.

Factors affecting Equilibrium (notes and practice). 5 pages. Very methodical, questions for CFU. Equilibrium Constants are covered next topic, so there is no discussion about changing Keq

Le Chatelier's Principle. By "Professor Dave", only 4 mins. Spot on for our course. Very direct and well explained.

Worksheet, 2 pages with answers (3rd pg) This link goes to a teacher's site...who is "mm?". Good worksheet.

Worksheet, 2 pages. This is from a media site called gbr? Wierd, but a good worksheet.


7. Equilibrium Constants
Unit 3 Topic 1 (Yr 12 Week 1 3 lessons)

The Equilibrium Constant (notes and practice). 3 pages with questions. Was a CK-12 but heavily heavily edited. Some easy questions, but check out the vid below for help with the harder ones.

Using Keq to calculate concentration changes. A video by "professor dave". Nice structure of his solutions, worth learning as his technique can be used for all types of concentration and Keq questions

Keq worksheet and ANSWERS! Need to scroll down to worksheet 11 answers. Stole this from Mark Iannone's site (see below). Amazing work by him


Review of Equilibrium

66 pages of Equilibrium Qs. and ANSWERS! by a teacher in British Columbia, Mark Iannone. Hat off to this guy, massive amounts of work. I will try and organise it a bit for this course (with some local files below... eventually), but all credit to Mark for this work!


Data test practice

Worksheet - data test style questions practice. 8 pages of questions. This was difficulty to compile, but should provide the type of thinking required to do well in a data test.

My answers to the data test practice questions. Be nice. These are my answers and they may not be perfect. Your teacher should explain the nature of marking in the data test in order to understand why these answers are written the way they are.


8. Acids and Bases - Bronsted-Lowry model
Unit 3 Topic 1 (Yr 12 Week 4 3 lessons)

There are lots of little ideas in this topic so a variety of notes are needed. The notes below cover this topic except for SC34 (amphoteric) which will be covered in class discussion. The notes are not in the same order as the SC, but do logically follow a sequences of ideas.

Intro to acids and Bases. By Crash Course (11+ mins), general inro, covers key ideas for this topic without too much detail. HAs some real life implications.

Acids and Bases - Introduction(notes and practice).

Bronsted-Lowry acids/bases. Very specific short (3+ mins) covering Arhennius and Bronsted-Lowry ideas of what an acid or base is.

Cojugate Acids and Bases (notes and practice).

Strengths of Acids and Bases (notes and practice).

Strengths of Acids and Bases. By Fuseschool (5+ mins). Very uncomplicated, perfect for this point in time as it does not discuss Ka, just the idea of strong vs concentrated.

Buffers (notes and practice).

Buffers. Crash Course vid (11+ mins). Good coverage, but longish.


9. Volumetric Analysis
Unit 3 Topic 1 (Yr 12 Week 5/6 6 lessons)

Best to recover the idea of pH/pOH and neutralisation as these are key ideas for this topic, but were last covered in Unit 2. Worth warning your students prior to the lesson so they can do some work beforehand. Students will have little practical experience of titrations so the practical aspect will take some time with students - six lessons is not actually very much for this topic.

Volumetric Analysis (notes and practice). Covers titrations and calculations of concentrations and titration curves. Notes were borrowed but heavily edited for this course.

Need to do a mandatory titration practical. Most texts will have a method.

Performing a titration. Witts Uni video (6+ mins). Nice and simple for high school. Does not cover rinsing pipette or burette as prep for titration (see video below). I could not find a video which mentioned the need for waste beakers.

Rinsing and filling a burette. A good video (4+ mins) except that the top of the burette is clearly too high. The volume marking on the burette should not be above eye level.


10. pH scale
Unit 3 Topic 1 (Yr 12 Week 7 3 lessons)

This topic discusses Kw before the course covers the Ka concept, which is the next topic. I think i will cover the simple pH calculation but then cover Ka and Kb, and come back to more complicated pH, pOH, and Kw calculations

pH, Kw and pOH. Video (13+ mins) by Dr. Allison Soult of Uni. of Kentucky. Covers all 3 Success Criteria. Will use for notes. In case the course becomes unavailable, hard copy here


11. Dissociation Constants
Unit 3 Topic 1 (Yr 12 Week 8 3 lessons)

Calculating Ka, Kb, pH, and pOH, (notes and practice). brief - 2 pages. Started with ck-12 but edited heavily. Some practice questions.

Ka and Kb worksheet. Stole this from "Mr Weathers" and edited slightly. Good sheet with some simple but comprehensive Ka and Kb Q's.

Calculating pH from Ka. By The Science Classroom (6+ mins). Well set out and explained.

Challenge - Next level: Calculate the pH for a mixture of 50 mL of 0.2 M CH3COOH and 20 mL of 0.1 M NaOH (Ka for CH3COOH is 1.8 x 10-5). For a slightly harder question, calculate the pH at the equivelence point in a titration of 50 mL of 0.2 M CH3COOH with 0.1 M NaOH. The answer to the second question is here. This calculation is next level for us.


12. Acid/Base Indicators Unit 3 Topic 1 (Yr 12 Week 9 3 lessons)

Indicators (notes). brief - 2 pages. No questions.

Questions (practice). Not complicated, fairly simple, 10 Q's.


STUDENT EXPERIMENT:
Yr 12 Week 10 to 15(9 lsns in total)

Student Investigation task sheet - NOT AVAILABLE YET, released in week 10

Write a GREAT student experiment - Guide to writing a great report. Seven pages packed with my personal opinion on "how to". This should be beside you as you write your report, but as always... you are all grown up now, so you are welcome to make your own decisions.

Student Investigation Example - this is more a learning task than an exemplar. I ask students to grade this report (and it is not neccesarily an A standard) using the criteria of the ISMG on the back page. The individual criteria have been split up and distributed at the relevant part of the report so it should be easier for students. More importantly, after the students try to mark the report it should be very clear to them how obvious they have to be when they write their own report.


Term 1 - Week 10

Unit 3 Revision
(3 lessons)





UNIT 4

Unit 4 Learning Goals and Success Criteria



15. Structure of Organic Compounds Weeks 13 - 15 (6 lessons)

Organic Chemistry Basics Part of a text from Siyavula. Covers some of the language and basic knowledge (eg. condensed vs structural formulas) needed to begin Organic Chemistry.

Organic structures. Part of a text from Siyavula. Good intro to basic structures (without nomenclature). Does not cover nitriles, amines or amides so need to add these as notes.

Organic Nomenclature. - Again from Siyavula, so it covers all the functional groups except nitriles,amines or amides so need to add these as notes.

Organic nomenclature - one of the more readable guides to organic nomenclature. 18 pages long and some good detail without being too detailed. Does not include haloalkanes or nitriles - have to add them as notes. Hard copy is here.
