Year 11 CHEMISTRY

TERM ONE

10 weeks (30 lessons, 35hrs max.)

Learning Goals and Success Criteria - for all topics covered in term 1.

1. Atomic structure and Isotopes - Week 1 (3 lessons)

Homework sheet 1 - Atomic structure and Isotopes

Intro stuff (Success Criteria 1 to 4)

Atomic Structure Basics - Four slides then a quiz - from Annenberg Learner. Covers atoms and periodicity. Should already know this (We may make some notes...depends). Must do the quiz to check for understanding.

Nuclear Binding Force - Not in our success criteria, but interesting knowledge. This is the last time we will look at the nucleus. Chemistry is all about electrons from here on in.

Simulation - Build an Atom - A PhET Simulation. Simple, asks students to build atoms from sub-atomic particles.

Relative masses,charges and positions of the subatomic particles - IB video by Richard Thornley

Nuclear Symbol Equations - IB video by Richard Thornley

Worksheet - Nucear symbol notation - Stolen from California State Uni. Northbridge website here

Electron configeration (Success Criteria 5 to 7)

Note there are no success criteria relating to the Bohr or Quantum Mechanical models of atoms. However it is important that students move their thinking from the simple ideas of electron shells (in the Bohr model), to the idea of shells, subshells, and orbitals (in the QM model) because students must learn to apply the Aufbau principle, Hund's rule, and the Pauli exclusion principle. I will use a brief class lecture to move from the bohr model to the QM model without making notes.

Bohr model to QM model. This is a good (but relatively straight forward) summary, but does not fully explain the shortcomings of the Bohr model and why the QM model is better.

Suggested (simulation) experiment - Rutherford's Gold foil exp

Worksheet: figuring out the rules for electron arrangement - some Critical Creative Thinking. Use for homework or maybe at the start of a lesson to try to generate some analysis and logical thinking processes.

Electron configurations for atoms and ions up to Z = 36 - an IB video by Richard Thornley. 15 mins long. Step by step process is explained

Notes and Interactive - Click on "it's elementary" in the top menu. Has slides with notes on Orbitals and writing electron arrangement, plus a "Building elements" interactive after 3 more slides. Good simple interactive - Use to CFU.

Interactive Periodic Table and electron arrangement - Click on the element and its electron arrangement is illustrated in energy level diagrams

Isotopes (Success Criteria 8 to 10)

Isotopes and Atomic Mass worksheet - a good coverage of knowledge and skill questions for this topic

Notes and a quiz Click Isotopes on the top menu. First page is notes, second is an online five question quiz by Annenberg Learner. Quiz changes each time you reload it.

Isotope simulation, PhET, Uni. of Colorado. - click "abundance in Nature" and "Symbol" buttons. Set questions for students to list the symbols and abundance of isotopes of certain elements.

Compare the properties of the isotopes of an element - an IB video by Richard Thornley (2 min)

Finish this section with students constructing a graphic organiser of Atomic structure (CCTS)

2. Periodic Table and Trends - Week 2 (3 lessons)

Homework sheet 2 - Periodic table and Trends

Online pre-test on Periodic table - Click on "Test your skills" in the top menu. By Annenberg Learner. Quite long, 39 questions. Some will be above students, so use this again as a post-test.

Blank graphic organiser (scroll down) - Direct Instruction. Teacher led. Collectively build a list of key terms and graphic organiser from existing knowledge. Two good sites for graphic organisers are here and here

The Periodic Table: Atomic Radius, Ionization Energy, and Electronegativity - by Professor Dave. Using the questions on following worksheet as a guide to make notes. Don't have to answer the questions exactly as your notes, but the notes you take should enable you to answer the questions.

Worksheet to go with video above - use questions on the worksheet to prompt the notes you need from the video.

Worksheet on graphing Periodic Trends - a pdf, can do graphing by hand, but challenge students to graph on excel without retyping the data (download, open with word, paste data into excel)

Periodic table data from Mrbigler.com. - This is an excellent spreadsheet prepared by "Mr Bigler and available from his site here - click some of the bottom tables for trend data.

Trends in Atomic Radii - an IB video by Richard Thornley

Trends in Electronegativity - an IB video by Richard Thornley

Trends in 1st Ionisation Energy - an IB video by Richard Thornley

Worksheet on Periodic Trends - lots of review and trends practice. Has answers so no stress.

Notes for this unit - Direct Instruction. Clearly link succesive Ionisation Energies to electron configeration.

Questions on succesive Ion Energies - only a few questions, but excellent for CFU.

Answers to the worksheet above on succesive Ion Energies

Reactivity Group 1 and 7 - Direct Instruction. Introduce video, discuss with students. Watch again, students summarise. An IB video by Richard Thornley.

5 trends in Group 1 and 7 - discusses specific trends in Group 1 and 7. Students take notes. An IB video by Richard Thornley.

Changes of ionic to covalent,basic to acidic,of period 3 oxides - Direct Instruction. Introduce video, discuss with students. Watch again, students summarise. An IB video by Richard Thornley.

3. Chemical reactions - Week 3 (2 lessons)

Probably only need one lesson as balancing will be assumed knowledge (no Hwk Sheet)

Observing Chemical change - students can make notes from this for SC 1. Video by Bozeman science (5 min)

Balancing and states in chemical equations - simple video from Fuse school

Worksheets for balancing - list of printable pdfs, with answers. Two online quizzes are at the bottom

4. Mole concept & law of conservation of mass - Weeks 3,4,5 (7 lessons)

This topic was covered in year 10 PCS and most students should already have a good background in this topic

Homework sheet 4 - This has a few tough ones. There are a couple which are double starred and these are extension work for those wishing to either drive themselves mad, or exhibit mastery of the mathematical process in this section of the course.

Hwk sheet 4 Moles ANSWERS

The 3 videos below give a basic idea of the theory and calculations involved in Empirical and Molecular formulas. The calculations can be intuitively learnt or taught as a series of process. Students will differ as to their preferred style. Direct Instruction with structured notes and the videos as support may work the best.

Calculating Empirical and Molecular formula - 5 mins by FuseSchool. Nice simple intro explaining these two terms and showing calculation of both. In less than 5 mins... sweet!

Empirical and Molecular formula worksheet. Nice worksheet (only 7 Qs), not mine, stole it from Peoria Public schools in Illinois here, where it has answers.

Second Worksheet on calculating Emp and Mol Formula - more questions, less formal phrasing. Not mine, but can't find original author. The first page has Qs, the second page has the answers.

Mandatory practical - use one of the two options below. The first is a simulation, second is an actual lab experiment

Simulation - Calculating the empirical formula of Copper oxide

Experiment - determining the empirical formula of MgO - simple, as you would expect. Can use glass wool to stop some of the smoke escaping.

The Mole - Students need to get a really good fundamental understanding of the mole and the basic calculations. This knowledge will be visited frequently in Units 3 and 4 (Yr 12). The videos here are mainly support material and I will not use them in class.

The mole - a series of videos - by Tyler DeWitt. A collection of 11 videos (vids 1,2,5,6 and 8 are most useful)

The mole - by Brainstorm, essentially the traditional teaching lecture about what a mole is.

Mole and Molar Mass - by JFR Science, good, succinct, and usful intro to the calculation of n.

Calculating mass and moles - A tyler Dewitt vid, good simple and clear. Not exactly how I do it in class, but comprehensive.

Stoichiometry - how to do - My own video (33 mins). First video of mine (a few things to improve) - shows my method for doing these Qs. Covers all the basic types of Stoichiometry questions

mass to mass simple 3 step Stoichiometry questions - need to be able to do these in your sleep!

Stoichiometry Worksheet - range of questions. Good intro to exam style questions although none are "extension".

Suggested practical - use the one below, or the traditional experiment of formation of Lead Iodide.

Experiment - Law of Conservation of Mass - Simple but effective online instructions, reaction between Barium chloride and Sodium sulphate. Tabs at top have supprting video and theory.

Lead Iodide Exp - excellent Limiting Reagent experiment. I stole this from a site and rewrote quite a bit of it.

Limiting Reagent - by Tyler DeWitt.

Simulation - reactants, products, and leftovers. - PhET by Uni of Colorado.

Limiting reagent questions - These are the hardest style of Stoichiometry questions

How to Solve Problems on Theoretical, Experimental and Percentage Yield - an IB video by Richard Thornley

Percentage yield questions - an extra step on the regular stoichiometry qs

Measurement uncertainty and Error - Weeks 6,and 7 (6 lessons)

The resources below are pretty much all videos. We will be using our text for practice qurestions and notes. This topic was extensively covered in Year ten, so reviewing those notes would be very useful.

Accuracy and Precision - an IB video by Richard Thornley

Worksheet - Accuracy and Precision - not mine. Super Simple - should use as a whole class exercise rather than individual work.

I do not have a lot of resources for these SC. Most I will cover with Direct Instruction and modeling of processes. I will preview each process using the videos below and use them to form the basis of the notes and examples for students. For independent practice I will go back to the conservation of masses experiment (or any other quantitative one) and apply the processes to the data.

State random uncertainty as a uncertainty range - an IB video by Richard Thornley

Determine the uncertainties in results - an IB video by Richard Thornley

State uncertainties as absolute and percentage uncertainties - an IB video by Richard Thornley

The appropriate number of significant figures - an IB video by Richard Thornley

Describe and give examples of random uncertainties and systematic errors - an IB video by Richard Thornley

how the effects of random errors (uncertainties) may be reduced - an IB video by Richard Thornley

6. Compounds and Mixtures - Week 8 (3 lessons)

May not need the whole 3 lessons as these ideas are not complicated nor need practicing.

7. Exothermic and Endothermic reactions - Week 9 (3 lessons)

LG and SC

This section will be split into 3 distinct lessons. Furstly an introduction to enthalpy, lots of definitions, diagrams, understanding. Secondly will be calculating Change in Enthaply using Bond enthalpies and calorimetry. Third will be a mandatory calorimetry experiment.

Resources for the first lesson - may do the notes and go straight to calculating Change in Enthalpy using bond enthalpy

*Notes for the first lesson - Need only the first 3 pages. We will do some highlighting and discussing, and work through the questions. One of the SC is not covered by these Qs.

Enthalpy - by crashcourse chemistry. Good Background and overview. Watch but don't take notes

*Worksheet on Enthalpy and Stoichiometry - nice simple questions, good intro. Adapted from http://mspeavychemistryclairemont.weebly.com/uploads/6/0/1/5/60154085/16-3enthalpystoich.pdf

Resources for the second lesson

Calculating Enthalpy change using Bond Enthalpies - fousses on "how" to do the calculation, not the "why" but quite clear and methodical. I recommend seperating the reactant calculation to the left of the page and the products to the right for more structure to your answer.

Calculating Change in Enthalpy for Bond Enthalpies - a one pager edited and stolen from Mr Kent's Chem page here. Practice only simple ones of these.

*Worksheet on Bond energies - good place to start. Has only one combustion Q though, which are the focus for this unit.

Me teaching Calorimetry - Experimental calculations of change in Enthalpy for reactions

Calorimetry Worksheet - looks very messy as it has the answers with it.

I recommend doing some of the Fuel calorimetry questions from the two sheets in Section 15 below

Resources for the third lesson

Classic Zinc in Copper Sulphate - seem well set out, I like the graph extrapolation, nice touch.

Calorimetry experiment simulation - probably best to start here, as we can do a "real" fuel experiment in next section (FUELS). Use to gather data, and do calculations.

REVISION - Huge worksheet - range of questions, do not do them all, ask your teacher for some on topic one's

Worksheet on range of Questions - more questions here than you need. We will do only some in class.

Data Test Week 9

Data test practice - there are a few sheets here. The first four were done in the week or two prior to week nine. The last practice sheet "revision for data test" provides the most comprehensive set of practice and was the last sheet given out in class (on wednesday)

Data and Questions on the Magnesium Oxide Empirical formula

Data and Questions on periodic trends

Data and Questions on Successive Ionisation energies

Data and Questions on Periodic trends No.2

*Revision for Data test

*ANSWERS Revision for data test -and yes the errors i made (no-one mention that out aloud!) have been corrected in this copy (and highlighted so you know where they are).

8. Introduction to Bonding - Week 10 (3 lessons)

LG 1:Students can write and describe the exchange of electrons in compounds formed from ions (ionic compounds)

Collaborative groups (CCTS), teacher led Direct Instruction - The key question in this LG is "Why do elements react the way that they do?". But to answer this students must first understand... what does "react" mean in chamistry? Works in small groups on this latter question. When the class has a satisfactory answer, try the first "key" question, again in groups. Teacher to make notes on electron exchange and electron sharing (via electron configeration and electronegativity, ion formation, electrostatic attraction) from class discussion. I think it is a good idae to introduce electron exchange (ionic) versus electron sharing (metallic and covalent) The videos below are good for students who want to prepare early, or struggle with the ideas.

Introduction to ionic bonding - creating ions and electron transfer. Part of a very old video series and not one I own, so this is breaking copyright. However I can no longer source this video commercially and despite low resolution it is excellent.

How ionic lattices form. Part of a very old video series and not one I own, so this is breaking copyright. However I can no longer source this video commercially and despite low resolution it is excellent.

Valence electrons and the periodic table - Tyler DeWitt (Simple,Excellent)

Why atoms lose or gain electrons - actually called "octet rule and valence charges" - it claims to be clear and simple and it actually is

Writing chemical (ionic) formulas Tyler Dwitt - good simple introduction

Checking For Understanding - The next resource is a good checking for understanding worksheet. It is adapted from an exam question released years ago in a C2C exam.

The periodic table on the planet MuAran If you can do this you know all you need to know about electron configeration, electron exchange, ions and ionic formula.

Worksheet Comparing Ionic and Covalent - a one pager, nice simple check for understanding

LG 2: Students can draw Lewis diagrams of simple ionic and covalent formula

Direct Instruction - Direct instruction on Lewis diagrams is important here, covering both ionic and covalent. Most Lewis diagram worksheets will cover only covalent molecules. Model drawing valence shells, electron counting, electron exchange (ionic), and electron sharing (covalent)

Excellent -Lewis diagrams - an ACS Chemistry page. Written from a teachers point of view. Has great Video, recommend you Direct Instruction first, show video after or as you teach examples. Has a student activity sheet (right menu, quite long for about 9 Qs), and answers

Lewis diagrams for covalent molecules - crashcourse, great inro and mentions the rules for drawing lewis diagrams, simple molecules only. Hint play at 0.8 speed.

Lewis diagrams for covalent molecules - Sciencepost, very useful tutorial, gos thru some simple and then some more complex lewis structures. A good follow up to the crashcourse video.

LG 3: Students can explain that basic differences in the physical properties of Ionic and Covalent substances using basic description of lattice and molecular structure

NOTE: LG 3 leads direct to LG1 in the next section - in LG 3 "basic" relates most likely to the fact that chemical bonds hold ionic lattices together, but physical forces hols covalent molecules together. Use this to explain high MPt versus low MPt

Brief notes on Ionic Bonding Good to have in front of you for this lesson or use as study notes

Covalent Molecular Bonding brief notes - need only page 1 notes (ignore the table of molecule structures)for this LG

Properties of ionic bonding - not professionally produced but well explained

MC quiz on Ionic Bonding

Quiz (easy) on Covalent Molecular Bonding

TERM 2

Learning Goals and Success Criteria - for all topics covered in term 2.

9. Bonding and properties - Week 11 (3 lessons)

LG 1: Students can describe and identify the type of bonding present in simple ionic, metallic, and covalent substances.

I use Direct Instruction a lot here as I find this topic is mainly memory work for students - so study notes and remembering are key. They do need to understand the bonding models in order to use them to explain, but any exam question on this will require students to remember the key points of a bonding model in order to explain a property. CCTS will involve interpreting data in order to identify the bonding type, but from there on its memory work.

Notes on all bonding models and properties Good for study notes.

Brief notes on Ionic Bonding Good to have in front of you for this lesson or use as study notes

GCSE Science Chemistry Properties of ionic compounds - not exciting but very on point. Exactly what you need to know and understand and no more.

Metallic bonding Mexus Education - an oldie but a goodie.

Brief notes on Metallic Bonding

Quiz on Metallic Bonding

Properties of ionic and Covalent Online quiz - Doc brown site - good simple revision for properties and bonding - will do as whole class exercise. Note, give the Qs a few secs to load, and questions may not load in all browsers (chrome works,IE not)

Practice short answer questions on Metals

Covalent Molecular Bonding brief notes - need only page 1 notes (ignore the table of molecule structures)for this LG

Simple QUIZ Chemical Bonding Good to do once an introduction of the three bonding models is done

Chemical Bonding Questions - great range of multiple choice and short answer questions. Good homework sheet

10. FUELS - Week 12 (3 lessons)

These SC and LG are not Knowledge based and this topic is very much research based. I believe the QCAA have this topic here only so it can be included a topic in the research investigation. There are a couple of worksheets with calorimetry questions below, but the bulk of these lesson will be developing research questions about fuels and finding data to answer them. We start the research Task next week.

*Calorimetry of Fuels worksheet - only 3 questions, but with answers. original is not mine.

Fuels and Calorimetry - variations in fuel calorimetry questions. Bit harder than simple application of process. Also with answers. Original is not mine.

STUDENT RESEARCH INVESTIGATION - : weeks 13 - 16 (2 lessons per week, 8 lessons)

Below is the task sheet. By far the hardest part of this research investigation will be finding data to develop a research question. Once you have done this and it is okayed by your teacher, the two supporting documents should make it easier to write your report.

Research investigation TASK SHEET - This is the 2023 version.

The next two documents are to support you writing the report for your investigation.

How to write your research Investigation report - this is a key document. It contains recommended heading and sections (subheadings) for your report. Each subheading is explained in terms of what you need to write aboute and the criteria which will be used to evaluate your writing. This doc and the next one work together.

Instrument Specific Marking Guide (ISMG) - What I will be using to mark your Research Investigation - a mark out of 20. Can be confusing. The next document attempts to unpack it for you.

The ISMG EXPLAINED - useful document as it uses some common and simple language to explain each of the criteria in terms of what your teachers are looking for.

11. Intermolecular forces - Week 13 and 14 (6 lessons)

LG 1*: Students can explain the relative physical properties of covalent molecular compounds using theories of intermolecular forces.

This is a complex topic, but not simple CCTS, more like a process type problem solving CCTS. I teach this as a combination of process (steps to follow) and logic application with lots of examples. Constant feedback to students is essential, along with Practicing and Deepening. I use lots of impromtu CFU followed by Practicing and Deepening The idea of a Flipped classroom is very useful for this topic.

VSEPR Theory.

Covalent Molecular Bonding brief notes - need only page 2 of the notes for this LG

Worksheet VSEPR theory - a "how to" guide. 3 pages, notes, guided practice. My version of how to do this. Check the notes on the front page.

VSEPR Theory - Science post, very methodical and clear but more an "explanation of" rather than a "how to" video.

VSEPR Theory - Tyler DeWitt, more of a "how to" video, not the same but similar method to mine.

Practice in VSEPR Theory - Tyler DeWitt

Madatory Practical - practice VSEPR theory using 3D model kits

Polarity

I use this video as a basis to make notes. Quite thorough. This is a complex topic and builds upon VSEPR Theory.

Polarity in covalent molecules - Sciencepost, very methodical and clear. 15 mins long.

Intermolecular forces

My prefferred technique here is Direct Instruction. I use the flowchart to proceduralise (am I making up words here?) this topic. The video is good preview material or for additional support for students. One document has 6 pages of mainly MC questions, where you will find some Qs to use for CFU and Practice and Deepening.

Intermolecular forces notes - good basics. Work for your study notes is highlighted.

Intermolecular forces flowchart - This is an excellent tool for predicting the melting and boiling points of compounds. It may also help you organise you thoughts on the 3 types of Intermolecular bonding

Intermolecular forces - by Dr Paul McCord. Good coverage and very clear

Questions (tradional exam style)on covalent molecular bonding 6 pages of questions

12/13. Reactions of Acids/Bases and pH - Week 17 and 18 (6 lessons)

This section actually combines two topics in the LG and SC document. These two topics are both knowledge based, although pH requires simple calculations

Notes for Reactions of Acids - an edit from a site called Naturez-Vous. Will go through these notes for knowledge and understanding work.

pH basics - notes and calculations on the basics of pH

Aqueous Solutions and Molarity - Weeks 19 and 20 (4 lessons)

Success Criteria 71

Water Structure and Hydrogen Bonding - by gmcd1985. Published on Feb 11, 2011. 2 mins.

Properties of Water | Hydrogen Bonding in Water | Biology | Biochemistry - Socratica. Published on Jun 26, 2017. 13 mins.

Success Criteria 72 and 73

Good source of notes for these SC - from "MrsGetson" site. If it does not load, I stole a copy here , call me paranoid!

Distinguish between solute, solvent, solution and concentration - an IB video by Richard Thornley

Success Criteria 74
Mainly direct instruction here as these calculation are very process orientated. These calculations are throughout the course, so reinforce to students that they need to be bullet proof with their confidence. Can use the videos as an intro and to support students who need additional time. Note the SC does not mention dilutions but I think it is appropriate to cover it here (first video).

Molarity, Solutions, Concentrations and Dilutions - Mr. Causey. Published on Jun 18, 2012. 10 mins. Nice and direct.

What is a Part per Million (ppm)? - an IB video by Richard Thornley. 6 mins.

Solve Problems Using Concentration, Amount of Solute and Volume - an IB video by Richard Thornley. 2 mins.

Simple Concentration questions Adapted from a "MrsGetson" who had answers. I have edited it significantly down to one page, no answers (we will generate them in class), and converted to word.

Molarity and Stoichiometry - these questions are harder and combine stoichiometry with Molarity, has answers. Not sure of the original author, but is heavily edited.

Suggested Experiment - CCTS - the experiment below provides an opportunity for students to develop the idea of "modifying" an existing procedure - an important part of their student investigation next term. Theory is simple so I will concentrate on what modification they are going to make AND data analysis (specifically graphing, identifying mathematical relationships, uncertainty, and error. Excellent practice for their assessment next term.

Suggested Exp - Effect of Conc on Rate - an RSC experiment. Use as a basis for students to develop modifications and practice data analysis techniques.

TERM 3

Learning Goals and Success Criteria - for all topics covered in term 3.

15. Rates of Reaction - Week 23 -27 (7 lessons of 15)

This is mainly a theory section with few calculations. The powerpoint below (first 14 slides only) and the Chemguide site link are all you will need for this unit, except for the experiments.

Reaction rates PwrPt (need only 14 slides, not all) - Will give you a handout of slides 3 to 14. This is 13 year old powerpoint so be nice! This resource covers the theory component of the course and I will use it in class. We will NOT cover the reaction mechanisms part, so you need only the first 14 slides.

Reaction Rate Theory - Chemguide site and excellent! It is broken up into different topics so is bitesize and easily navigated.

Exp - Effect of temp on rate - We will do a version of this one in class (and vary concentration as well). This is a Royal Society of Chemistry site, experiment sheet (scroll down) for measuring the effect of temp on a reaction

Exp - measuring rate of reaction - Royal Society of Chemistry site, experiment sheet (scroll down) for measuring the rate of a magnesium and acid reaction.

STUDENT EXPERIMENTAL INVESTIGATION : Weeks 23 to 25 ( 8 lsns)

Student Investigation task sheet

Write a GREAT student experiment - Latest (2021) version. Step by step, detailed and super, super useful if you take the time (9 pages) to use this how to guide.

Student Investigation Exemplar - SIMPLE - this is both an exemplar and a learning task. Student have to grade the exemplar (it has a couple of errors) 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 meeting the criteria when they write their own report

Student Investigation Exemplar - SENIOR LEVEL - This is also annotated to show how it meets the criteria. However the topic is more complex as are the arguements and logic in the report.

16. Solubility and Identifying ions in solution - Week 30 (3 lessons)

LG and SC

Notes on Solubilty

Solubility worksheet - some really good simple and some not simple practice. Edited this sheet from somewhere, can't remember where.

17. Gases - Weeks 29 (3 lessons)

Success Criteria and Learning Goals

Homework sheet 5 - Cover this section on gases.

Hwk sheet 5 Gases ANSWERS

Reference Texts - general theory for this course. The first is most appropriate for this brief coverage of gases.

GASES: notes - from chemguide.co.uk. Quite direct and well explained, not extensive, all you need to know for this course

Principles of General Chemistry - Chapter 10 Gases. Free to download, a creative commons licence

Kinetic Theory Notes and Questions Good summary and 3 excellent questions

KINETIC THEORY - Tyler DeWitt discuss Kinetic Molecular Theory (Part 1), good video

KINETIC THEORY - Tyler DeWitt uses KMT to explain properties of Gases (Part 2), excellent video

GAS PRESSURE UNIT CONVERSIONS - Tyler DeWitt shows how to convrt between the units used to measure Gas pressure

KELVIN - ABSOLUTE ZERO - Tyler DeWitt discusses the idea of absolute zero temperature and Kelvin units

Homework Sheet 1 - written for 2018 course, but in WORD so you can edit as you wish. Has unit conversions, Kinetic Theory and boyle's law.

Answers to Homework Sheet 1

Some Direct Instruction and CFU(Teacher modeling and Guided practice) will be needed here as solving the ideal gas law questions are a process orientated activity - make sure to include calculating Molar mass. Opportunity do exist however for students to engage in CCTS by developing ideas about the mathematical relationships. The first resource below is an example.

See Think Wonder- on the graphs which describe Boyle's Law, good exercise. Do as individual, then collaborate, then with your teacher. Do the students see a mathematical relationship?

Homework Sheet Three - covers Ideal gas law and simpler versions of the formula along with units and Kinetic theory. Written for 2018 course, can edit to suit.

Answers to Homework Sheet 3

Worsheet - Ideal gas Law question - not mine. Good simple direct questions - excellent for CFU. Has answers

Solving a idel gas law question - Air bags - an IB video by Richard Thornley

An ideal gas Law question Good complex practice

Mandatory practical - determine the Molar volume of a gas. Use the either the simulation or the real life experiment below

Simulation of an ideal Gas - recommended by the QCAA, but I couldn't figure it out. Let me know if you know how.

Experiment - detemine the Molar volume of Hydrogen gas - an RSC publication. Can download a teacher and student handout here.

Suggested Experiment - determine the molar mass of the hydrocarbon in a disposable cigarette lighter. Problem solving (CCTS) for students. A classic, done by displacement of water. Can easily look up a link if you like, but I set it a a task and students figure it out themselves. Direct Instruction: review Stoichiometry. Note that this SC is NOT actually about the Ideal Gas law in SC 4, but is about stoichiometry and determining amounts of gaseous reactants and products at STP and SLC (SC 3).

Gas Law Stoichiometry Worksheet - not mine, was not certain of where this is from, found as a pdf here

Experiment on ideal gas law and Air bags - has multiple resources including an outline (but not a method, so good CCTS) of an experiment.

Check the bottom of this page for additional resources on Gaseswhich are not needed for this course. They have additional worksheets and homework sheets (can harvest questions from them) and work on partial pressure and "real" gases

18. Chromatograpy techniques - Week 15 (3 lessons)

The success criteria in the TLAP does not indicate theoretical depth here, so I am going to teach the theory of chromatography using the partition explaination. This is the explanation used in the YouTube clip below (without the big words!). Key terms - stationary phase, mobile phase, Retardation factor, polarity, adsoption, desorption, eluent, retention time.

How TLC Chromatography works - a vtchemist video. Short and sweet on partition chromatography, uses no terminology.

Different types of chomatography - Khan academy. Start basic, discussing paper chromatography, then discusses the other types of chromatography.

calculating Rf values - by the khan academy. Nice. I've been made obselete!

Chromatography in brief - very brief notes, quite hard for studnets to interpret, but good teaching notes. Has a good brief summary of each type of chromatography.

Chromatography quiz - Click the "review questions" in the left hand menu. 15 questions, quite hard.

The rest of this page is currently under construction. The resources on this page from this point forward are suited to an older QCAA course. The following resources will not be updated or organised and eventually deleted as the new QCAA curriculum becomes bedded down.

Worksheet on classifying matter - very simple classification of substances according to some of the vocabulary students need to develop in this section.

Text on Acids and Bases - Chemlibre text. Comprehensive for notes

GOAL: Describe a chemical reaction in terms of moles of reactant or product

The following three vids all address the mole. find one which makes sense to you. The mole is not a concept we actually assess you on, but is a vital concept for you to understand for the rest of the unit.

The mole - by Brainstorm

The mole and Molar mass - by JFR Science - very good

The mole - a series of videos - by Tyler DeWitt. A collection of 11 videos (vids 1,2,5,6 and 8 are most useful)

Simple mass, concentration, gas volume (STP) calculations - not involving a reaction (no balanced equation needed)

Calculation flowchart for basic stoichiometric Q's - my version of a maths map for beginning Chemists. Very customisable so change as you like. Updated copies with more complicated calculations appear in later units.

Stoichiometry (9mins) - by JFR Science - excellent and simple. At 3:45 the basic 3 step outline of stoichiometry is shown - very very important.

Also Stoichiometry (15 mins) - Mad Scientist - slower, more detailed and also excellent and simple

Stoichiometry - how to do - My own video (33 mins). First video of mine (a few things to improve) - shows my method for doing these Qs. Covers all the basic types of Stoichiometry questions

Complex question sheet - range of complex but closed questions on stoichiometry

Percentage Composition questions - these are a stand alone type of question, a different style to the others
