An introduction to the task in classA practical or activity which demonstrates and explains the principles behind the coursework (ifapplicable)Deadlines for the taskThe pages in the textbook which cover that task, or written guidelines for the assignment1 Page
What to Include in Coursework?An assignment brief will be handed out for each part during the assessment period. The brief iscomposed of different sections, these are highlighted below.Key information:Submission date: this date indicates when you maysubmit the assigned task.

FeedbackIn BTEC Applied Science, you will get support with any work you do notunderstand at any point during the lesson or during AST. It is important you seekfor support before the assignment is issued. The teachers cannot provide helpwith how to construct the assignment or any questions specific to the assignment.1. Teaching time in classa. Most pieces of coursework will start with teaching time where youtake part in activities and lessons to learn about the assignment topicyou will write aboutb. The taught material often ends up supporting the assignment – it’svery important that you catch up with work you miss as quickly aspossible or you might not understand any of your assignment at all2. Final deadlinesa. These are when you hand and sign in your work to be marked for thefirst and final time, and these are the marks which make up your finalgradeb. Any work handed in late can only achieve a pass as the maximumgradec. Every task in the assignment must be properly referencedd. A declaration form must be signed to declare that the work handed inis your own and free from plagiarism.You canobviously alsoask yourteacher forhelp in class, orif you arrangeto come andsee themoutside oflesson time.Each deadline needs to be met otherwise the maximum grade you would achieve for that assignmentwould be a pass.

How to Hand In WorkFormat of your work Font: Calibri (body)Font size: 12Line spacing: 1.5All work must be properly paragraphedMargins: Normal setting (Top and bottom, Right and left: 2.54cm)Header should include your full name (top left corner) and the assignment title andtask number Eg: Unit 2, Aim A: Preparing and testing standard solutions.All assignment work is due on the date and at the time specified. There will be a declaration sheet which must accompany each assignment you handin.You must sign your work in – the teacher will not sign until they have seen yoursignature and your workIf you are off sick on a deadline day, then the work may be submitted as late You do not wait until the next lesson – this would mean that you would have moretime than other students which is an unfair advantage.If you wait until the next lesson, your work will not be accepted.You must provide any relevant form of evidence for any late submissions. This willthen go for approval by the internal verifier.All work must be handed in to the teacher concerned. Do not try to leave it with another teacher to pass it on for youDo not leave it on desks or pigeon holesDo not leave it at reception or in labs/classroomsIf you do any of these things your work will not be accepted.Do not wait until the last minute to print your work Excuses such as ‘lost USB, broken USB, broken printer, forgot to e-mail work, fullLRC’ etc. are not acceptable as excuses.You will not be allowed to email work to your teacher Too many people have said they would do this and not, or sent it well after theagreed time, or “forgotten to attach” the file when sending the email.Some people are doing this for every piece of coursework, which is unacceptable.You will be asked to email your work by a process of random selection after yourdeadline has passed. Only certain students will be selected. This is to check forplagiarism. Absences If you know in advance that you are going to be absent for a deadline day, forexample visits and holidays, then you must submit your work before the deadline tothe teacher concerned.5 Page
Even if you miss a lesson, you are still responsible for the work and the deadlineswhich are set in that lesson. If in doubt, speak to your teacher. Do not trust yourclassmates to just tell you if you missed anything important!6 Page
Written Work and Standard FormattingScientific Writing1. Check your spelling, punctuation and grammar before you hand in the report.Spellcheck should go without saying but you really need to read what you’ve writtenas well to make sure it makes sense. Spellcheck is sometimes actually wrong fortechnical terms and phrases, and it’s pretty poor at picking up on bad grammar.2. Explain any word you don’t understand. It is very likely that your teachers will knowif you’re blagging it. They may simply decide to give you the marks anyway if the restof your report shows a good understanding, but this doesn’t happen often.3. Style – this is not an essay or story. Scientific writing should be to the point, conciseand accurate. Opinions, first person (I, we, you) and other things which give yourwriting any hint of a personal note or bias should be avoided. You can think ofscientific language as being like a new language – you wouldn’t go into a Sociologyexam and write the answers in French, because you wouldn’t get the marks even ifyour answers were right. Similarly, you should ensure that all your scientific work iswritten in the appropriate scientific style.4. Following on from the previous point, be very, very sure that it is appropriate to usethe following words before you put them in:a. Howeverb. Furthermorec. Moreoverd. Wherebye. In additionf. ConsequentlyWhilst these words are extremely important for getting evaluation marks in. Theysometimes work in an evaluation section, but not always. It actually makes yourreport sound less good if you use fancy words in the wrong context.5. You should never use the above words words as part of a method – they don’t makesense.Good phrases to use in a method instead are: “The mixture is then ”; “Followingthis ”; “In the next step ”6. Use “this”, “it” and other pronouns sparingly. Make sure it is very clear and specificwhat chemical or process you are referring to. It’s almost always better to say thename of the chemical. Try using “species” or “chemical” or “particles” (or “acid” or“salt” or whatever it is, if you know what kind of chemical it is) instead of “it” or“thing” if you really don’t want to say the name. To conclude: BE SPECIFIC7 Page
Technical WritingChemicalsFormulae1. Any chemical which you show using a formula should have superscripts andsubscripts where appropriateFor example, CO2 not CO2.2. A space means a new chemical. Never put a space in the middle of a formula.For example, CH3CH2CH3, not CH3 CH2 CH33. A chemical has one capital and one small letter, or just one capital letter. A newcapital indicates a new atom/element.For example, Cl not CL.4. Ionic charges go at the top.For example CO32- not CO32WrongCorrectCO2CO22HOH2ONACLNaClC2 H4C2H4Cl Cl OH-OH-The keyboard shortcut for a superscript is to press the Ctrl and Shift and / keystogetherThe keyboard shortcut for a subscript is to press the Ctrl and / keys together.8 Page
Both of these shortcuts are toggles – doing the same thing again will turn them onand off.You can also just press the X2 and X2 buttons at the top of the screen.NamesChemicals can be named according to whether they areinorganic (a metal and a non-metal)ororganic (hydrocarbons)Inorganic Compounds(First element name)(Prefix) (Second element name) (Suffix) Prefixes tell you about numbers of that element, but usually only apply to covalentcompounds (two non-metals bonding together)o Mono is oneo Di is twoo Tri is three Suffixes usually tell you what else is in that half of the chemicalo “ide” means there is nothing else combined with the element in that half ofthe chemical.o “ite” means a little bit of oxygeno “ate” means a lot of oxygeno “hydrate” means hydrogen and oxygenFirst element: SodiumSecond element: CarbonSuffix: “ate” (there is oxygen in the second bit of the formula)Therefore, this chemical is called sodium carbonateFor example: K2Cr2O7First element: PotassiumSecond element: chromiumPrefix: di (two chromium atoms)Suffix: “ate”Therefore, this chemical is called potassium dichromate9 Page

Reliability, Validity and AccuracyThere are three very important things you need to be able to say about scientific data:ReliableAccurateI always getthe same valuewhen I repeatmy experimentI havemeasured to auseful amountof decimalplacesValidI haveaccuratelyrepresentedthe real worldwith my testControl of VariablesEquipment andMeasurement ErrorsThoughtful Methods12 P a g e

List them in the space peedResistanceEMF/VoltagePressure13 P a g e
Units, Powers of Ten and RoundingUnits All numbers must have units, unless they are “just a number” (for example, pi is just anumber)There is a list of standard units in Appendix A: SI icant FiguresAre figures which represent “real numbers” –useful values telling you there are four tens(the 4 in 40) or 8 tenths (the 8 in 0.8).They do not include “placeholder zeros” – forexample, in 0.045, the 0 in the tenths columnafter the decimal place is not a significantfigure, in the same way as we would ignorethe first zero in 0450 (four hundred andfifty).The only difference is, for 0.045, we still haveto write the zero in the tenths column,because it is telling us that the 4 is onehundredth. It’s just a function of the way wewrite numbers in the decimal system.With significant figures, we startcounting at the first “real number” thencount all the digits after that. Therefore,0.020567 to three significant figureswould be 0.0205Decimal PlacesAre just digits which occur after the decimalpoint, including all zeroes.14 P a g e
So, 0.045 to one decimal place would be 0.0,two decimal places would be 0.05(remember to round up!) and to threedecimal places would be as written, 0.045If the question asked for four decimal places,you can simply fill in any extra slots withextra zeroes – for example, 0.045 becomes0.0450. These are known as “trailing zeroes”and show a good accuracy level of themeasurement. However, you can’t just addon zeroes unless your measurement wasactually to that many decimal places!With decimal places we start countingimmediately after the decimal point.Try the following practise exercises in rounding:1. 7.4562 toa. One decimal placeb. Three significant figures2. 0.0249 toa. Two decimal placesb. Two significant figures3. 0.0405 toa. Three significant figuresb. Three decimal places4. 0.834a. Four decimal placesb. Two significant figures15 P a g e

IntroductionsAn introduction should not start in any ofthe following ways:An introduction is there to do thefollowing things:“In this essay, I will be writing about ”(Not objective)Introduce the context“We have many chemicals in our world ”(Non-scientific style)Provide background information, and definekey terms“I am going to investigate ”(Not objective)Set out aims of a report“I am a scientist working for a chemicalcompany ”(Non-scientific, and plagiarised directly fromthe workbook!)Briefly discuss any research which alreadyexistsLook at the following introduction to a report investigating the purity of baking soda. What errors has the student made? What have they done well?Can you write a better introduction?In this report, I am acting as a scientist working at BakeChem company. I am testing bakingsoda for purity as part of routine quality checks. Baking soda is sodium hydrogen carbonate,NaHCO3. The company also produces and packages flour and sugar in the same factory.I will carry out three tests: A reducing sugars test for glucose contamination A titration with acid to find the percentage purity A visual test and starch test for flour A melting point test to see if the baking soda is pureThis practical should reveal whether the baking soda is of acceptable purity and, if not, whatis it contaminated with?20 P a g e
