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)

I have shared a class OneNote with you. In that OneNote, in your homework and submissions page is space for a "one-pager" study notes on Equilibrium and Acids/Bases (limit to one A4 page - scan it in or paste). There is also a page in your notes sections with Unit 3 Revision. This is the Public Exam questions which relate to Unit 3. The answers for the public exam are in the content library (which I am assuming you can all see). Email me with questions about access to the OneNote. Any significant questions about the work, put in the collaborations section, and email me to let me know the question is there. I will provide any answers in the collaboration section so everyone can view them.

Revision for Unit 3 - Q's from the public exam.





UNIT 4

Unit 4 Learning Goals and Success Criteria - Note these are a NEW version released 1st April.



4.1 Structure of Organic Compounds Weeks 11 and 12 (6 lessons)

Organic Chemistry Basics Background material you need to know. Read this, get some idea of the background knowledge you need, don't get depressed. Covers some of the language and basic knowledge (eg. condensed vs structural formulas) needed to begin Organic Chemistry.

Week 1 (3 lessons) - Start with the background stuff above. A copy is in the content library of your OneNote, copy into your own notes as background notes. Read as an overview, don't stress about detail, highlight key terms that look important. You will use these notes to come back to when you are unclear at the beginning. Then follow the sequence of tasks below. All of the work you will complete will be inside your OneNote homework tab (labelled Wk 1), so that your teacher can check it.

Week 1 video. My talking head and your success criteria. Should play in screen. If not, right click and save as. Explains what you can expect from the first week.

video worksheet - things to know. - SC 51. Complete this doc by watching the two videos below. The goal of this activity is to wrap your head around the language and the simple terms of organic chemistry. This doc is in your onenote or you can download it from here to fill in. The worksheet contains the terms used in the Success Criteria (and a couple extra). Onenote is not accessible during the day, so you could do this at night, or download this doc, add your name to the end of the file name, complete, and email to me.

Intro to Organic chemistry (Part 1) - by Melissa Maribel. Covers the language and names for this topic in two videos (see below). Use these videos to fill out the worksheet above

Intro to Organic chemistry (Part 2) - by Melissa Maribel. Ditto above

Now that your background knowledge is up to speed, let's look at the nomenclature (naming) of hydrocarbons, and structural isomers of hydrocarbons. Part of SC 52, and SC 53

How to name hydrocabons - notes. My own guide to nomenclature of bydrocarbons, keeping the language as simple as possibe. Good place to start. This is in the content library. Copy into your notes.

Naming alkanes Part 1 By Professor Dave. Nice clear explanation - no point me doing this, couldn't do it any better.

Naming alkanes Part 2. Second half of the above topic.

Naming Alkenes and Alkynes. Prof. Dave.

Naming Haloalkanes. Need only the first two mins of this video. Professor Dave again.

Naming Hydrocarbons - worksheet This is in your OneNote, you should complete it in there. Onenote is not accessible during the day, so you could do this at night, or download this doc, add your name to the end of the file name, complete, and email to me.

Naming Hydrocarbons - ANSWERS Did these last night.

The link below is just for reference. It does have a good explaination of the first point of difference rule in nomenclature of hydrocarbons.

the first point of diffrence rule. a simple explanation and how to implement it.

SUMMARY Week 1 - you should be familiar with much of the necessary language used in organic chemistry, know how to name hydrocarbons, and identify and name structural isomers of hydrocarbons (up to 6C's)

Week 2 (3 lessons) - This week we cover the naming of all the other functional groups and sterioisomers.

Functional group nomenclature notes (all pages). Nine pages of pure bliss! Covers all the functional groups we need in our course. I wrote this over the hols and tried to simplify the language but still be accurate with IUPAC rules - there may be typos. You have these notes in your Notes pages in the OneNote, so only copy these if you want a copy as one whole document.

By the end of this week you should have completed all the following worksheets (they are in your OneNote) AND have done Q's 1-5 (p.13); Q's 4,7,8 (p.15); Q's 2 (p.16); Q's 5 (p.17); Q's 2,4 (p.19); Q's 1,2,4 (p.21); Q's 4 (p.23); Q's 2,3 (p. 24).

Naming Alcohols. Ignore the first two mins on haloalkanes, the rest is on alcohols. Professor Dave again.

Worksheet - Alcohols

Naming Amines. by Leah Fisch aka Lea4Sci.

Naming Amides. by Leah Fisch aka Lea4Sci.

Worksheet - Amines, Nitriles, Amides

Naming Ketones. by Leah Fisch aka Lea4Sci.

Naming Aldehydes. by Leah Fisch aka Lea4Sci.

Worksheet - Ketones and Aldehydes

Naming Esters. by Leah Fisch aka Lea4Sci.

Worksheet - Esters

Naming Carboxylic acids. by Leah Fisch aka Lea4Sci.

Worksheet - Carboxylic Acids

Cis and trans nomenclature AGAIN. by ChemistNate. Watch until 5min 8secs, it covers E/Z nomenclature past this point. E/Z naming is used for more complex molecules, but our syllabus specifically mentions cis/trans for simple molecules.

Cis and trans nomenclature. by Leah Fisch aka Lea4Sci. Also covers cyclic cis/trans which we do not need to cover. Check out from 9:52 onwards though.

Basic IUPAC Organic Nomenclature. Useful site. Firstly scroll down and click on the functional group you want to learn the rules for. Secondly - at each page scroll down and click the "practice questions". By the Chem Dept, Uni of Calgary (Canada).

SUMMARY Week 2 - you should be able to identify the functional groups in a molecule, name a molecule with one or more functional groups, draw molecules given a name, identify cis/trans isomers and name or draw them.


16. Organic Macromolecules Weeks 16 - 18 (9 lessons)

Week 3 (2 lessons) - This week we cover SC (Success Criteria) 56 - advantages and disadvantages of polymer use; SC 57 - condensation polymerisation; and SC 58 - protein structure. This is a short week and most of the work is about you constructing notes on these three SC. It will takes some time. Note that the heading for these sheets use the number 2, as this is the second topic in Unit 4, and a, b, c to indicate the order of the subheadings.

Advantages and disadvantages of Polymers Complete this. A worksheet to guide you in constructing some brief notes. Your text does not address this SC very directly and we could not find many specific references online. There is some information in this resource which may help constructing notes. Note that the cognitive verb of this SC is discuss... so we believe this is a broad, overall topic (general ideas) rather than something which requires a lot of specific chemistry knowledge. This will be a simple but frustrating task. Do it reasonably quickly, don't stress. This worksheet is in your OneNote, in your homework tab, as Wk3 2 a Polymers - advs and disadvs

Notes and Questions on Condensation Polymerisation Read and complete this worksheet. There is a lot of information here, and this has to be read slowly and with care. The positive is that much of this information will also be useful later in this topic, so take you time to understand it now. This topic appeared so poorly done in your text and other texts that we wrote these notes for you. You do not need to "know" all of it, but you do need to understand all of it. You need to be able to do the questions with these notes. This will be difficult for you. I have included some videos below to support you - use them. There are 3 videos on polymerisation of proteins, and two on polymerisation of polyesters (none of carbohydrates). I recommend you highlight or summarise key points. This worksheet is in your OneNote, in the homework tab, as Wk 3 2 b Condensation polymerisation. When you have done the questions you should transfer the notes to you notes tab, and reposition the question answers to the top of the OneNote page.

The following three videos cover the condensation polymerisation of amino acids to make proteins. I have put them in the order I recommend you watch them. total of less than 12 mins.

GCSE Science Chemistry (9-1 Triple) Amino Acids - by freesciencelessons, 3 mins. Watch for the big picture idea of how proteins are made, but don't focus on the detail, the other two videos below do a better job on the detail. An english school video.

Condensation polymerisation of amino acids - Start absorbing detail here. By maChemGuy (7 min). Very old school, uses a small white board and models of molecules. But it is simple and direct.

Amino Acids and Peptide Bonds - Condensation Reactions - by 5minschool, 2 + mins. Good backup and reinforcemnet of what you learnt in the above video.

The following two videos cover the condensation polymerisation of diols (two alcohols groups) and dioic acids (two acid groups) to make polyesters. I have put them in the order I recommend you watch them. total of less than 13 mins.

Condensation polymerisation polyesters - Excellent video, but very old school. Pay attention, this guy does a good job. By NobleChemGuy, 8 mins.

Organic Condensation Polymers 1. Polyesters - Should reinforce everything you learnt in the first video. By FranklyChemistry, 5 mins

Notes on Protein structure Read these. These are note you may use to complete the worksheet below. see video below. These notes are in your OneNote, in your notes tab, as 2 c Protein structure.

Worksheet - to write your own notes, and two questions Complete this worksheet. The worksheet is in your OneNote, in your homework tab, as Wk 3 2 c Summary of Protein structure.

Protein structure. by Prof Dave. Very good, simple info for understanding this topic and making your notes. He starts with some nomenclature you need - the four types of structure follows.

SUMMARY Week 3 - you should be able to hold an informed discussion about the advantages and disadvantages of polymers; be able to identify condensations reactions and their products including polypeptides, polyesters, and polysaccharides; and explain the four structural facets of proteins. You have completed 3 activities this week.


Week 4 (3 lessons) - SC 59 to 60. Easy week as we come back to face to face learning and will spend some time this week doing a review. The Success Criteria 59 and 60 cover proteins and polypeptide macromolecules. Some of the work, regarding condensation polymerisation, has already been covered last week

Guide to making notes on Proteins as Enzymes (SC 59) - use this guide to Complete some notes on proteins as enzymes. Need the QCE Chemistry Unit 4 text book.

Proteins as Enzymes - by Libretexts. Has a good description of how the structure of the R groups of amino acids influences enzyme action. Stop at "cofactors" - gets too detailed.

Identifying the AAs in a polypeptide. The last five pages of this pdf contain one polypeptide per page. The previous pages show the structure of many Amino Acids. For each of the polypeptides identify the Amino acids within it, and list the number of water molecules produced by the condensation reactions.


Week 5 (3 lessons) - SC 61 to 65. These Success Criteria cover carbohydrates and fats. Some of the work, regarding condensation polymerisation of carbohydrates, has already been covered to weeks ago

IA 3 - Research Investigation

How to write a Research Investigation - get your data and research question sorted. Then read and follow this when you start writing.

Carbohydrates - Notes and Qs - covers SC 61 to 63. Summarise or highlight the notes, and answer the Qs

Fats and Oils - guide to notes - covers SC 64 to 64. Guide and Qs only - use these as a guide to making your notes form the text. There is an intro though, and some additional information about hard water which is not in your text.


Week 6 (3 lessons)

Becuase of the covid-19 alterations to timelines we have some time this week to go back and review this topic of macromolecules. There is only one new section of work - on addition polymerisation. The rest of the week we will go back over all the sections of this topic.

Addition polymerisation - Notes and Questions . Highlight the notes according to the SC 66 and 67. The questions at the end of the notes focus on the SC and are great exam practice for you.

Multiple choice quiz - covers SC 66 and 67. Edited - from an organisation called NAGWA.







Absolutely lovin' this organic chemistry..... so ... so .... easy to remember!!!
