Thanks to S Gray, Drummond Community High School, for putting together this book of experiments that you should have covered in your N5 Physics lessons. Any of these could be discussed in your exam as a question.
Lots of people are asking me about the answers to these North Ayrshire revision check tests. Can I also recommend you pop across to the Learning Outcome Questions, which have fully worked answer. Click on the links below. No cheating though!
Thanks to those in North Ayrshire who provided these excellent questions for you to get your teeth into. I’ll post the answers as password protected to protect those students and staff who are giving these for homework! They’re in the old order, so you’ll have to search through for the right section.
I’ve put together, with Mrs Mac’s help, a document with quantity, symbol, unit and unit symbol so that you know the meaning of the terms in the Relationships Sheet. It is in EXCEL so that you can sort it by course, quantity or symbol.
If you don’t know your scalars from your vectors try this….

I’ll add to this during the week as I have time
If you are doing a PROPERTIES OF MATTER TEST
Look over some OLD Higher papers for the Pressure and Gas Laws as well as the relevant past papers above. I’ll look out the papers with question numbers as soon as I can.
If you’re doing the Waves and Radiation UASP I’ll get some revision plans up soon
This is a ten week revision plan, put together by Mr A Riddell from “up North”. It will give you some ideas on how to break up the daunting task of revision. NB I’ll need to change this for the 2024date of 25th April for your exam.
It is important that you spend an adequate time on this homework (an hour is advised). If you complete this thoroughly you ought to have a good grasp of what is required for the Assignment at National 5.
List the five 2023 experiments that have been given as examples for the N5 Physics Assignment, and the further 5 from the 2018 experiments.
In the marking instructions for the assignment how many marks are available for the underlying Physics?
What are the six sections in the data collection and handling (and I don’t want 4a, 4b, 4c and 4d! BTW it isn’t even section 4)
Section 3e and 3f refer to literature and sources. State how you achieve these marks.
What are the marks awarded for when plotting your graph?
To achieve the mark for the conclusion, to what must your conclusion relate?
For candidate 1, how many repeats of the experiment did they make?
What did candidate 1 do correctly for the graph and what was incorrect?
Mark Candidate 2’s evidence (2023, “How changing the resistance effects current in a series circuit”) thoroughly yourself using the marking scheme and compare your answer to the commentary. Record your results and the comparison. Comment on both of these.
CHOOSE a topic that would be suitable using the Physics Compendium https://mrsphysics.co.uk/n5/ Research some Underlying Physics and find a suitable graph that you can try to replicate.
Here are a set of summary notes, I made a few changes and put them into a table rather than boxes to help the flow, not that anyone would know. Thanks to the teacher who produced these- sorry there was no name on them.
A bright 2 page set of summary notes for this topic. NB Please add to this “The length of the line for vaporisation should be longer than that for melting as more energy is required to change a liqued to a gas than a solid to a liquid.
A scribble from an online lesson. The last 2 comments are perfect answers for those “Explain using the kinetic model of gases….” questions.Using a simple syringe will remind you of Boyle’s Law, if you reduce the volume pressure increases. I know this as it really hurts my finger when I squeeze the gas into a smaller space or volume.just some scribbles from an online lesson. We were trying to remember which law went with which rule and this is what we came up with BOYLE’s LAW. If you had a big BOIL and you add pressure by squeezing it the volume increases as it splatters all over the place! CHARLES’ LAW, we know this guy called Charlie and when he gets red hot his face swells up (volume increases with temperature) And GAY-LUSSAC law has been incorrectly attributed to him so we can put him in a pressure cooker (picture below) and increase the temperature. The volume is fixed so we know the pressure increases as the cooker makes a big hissing sound when it’s about to blow!
Courtesy of Wikipedia
Gay-Lussac is incorrectly recognized for the Pressure Law which established that the pressure of an enclosed gas is directly proportional to its temperature and which he was the first to formulate (c. 1809). He is also sometimes credited with being the first to publish convincing evidence that shows the relationship between the pressure and temperature of a fixed mass of gas kept at a constant volume.
Maybe for the deception he should be sent to Pressure Cooker!
A Pressure Cooker
These laws are also known variously as the Pressure Law or Amontons’s law and Dalton’s law respectively.
Here I will post a few tips and hints to remember when answering SQA N5 Papers. Hopefully they’ll be quick, snappy and memorable. You’ve got the whole of the Scottish Physics Teachers’ Community Wisdom Below!
Tips to Aid Memory
Neutrons don’t carry/have (net) charge so aren’t accelerated/guided/ deflected by magnetic fields.
I.S.S. (current in series the same). I.P.A (current in parallel adds), USA (voltage in series adds), UPS (voltage in parallel same) OK you need to think of a U as a V but most of you write like that anyway!
Voltage dividers- think Kendal Mint cake!
Learn your 7 point plan!
Transistors act as a SWITCH.
Preparing for the Exam
Check out the past paper marking instructions for do’s and don’ts- its full of them in that second column!
Read the Course Reports, they give common mistakes that lots of students made and then you avoid these.
Make up flashcards, or cue cards and leave them where you go most often, (e.g. biscuit tin, phone, computer, loo). Don’t let yourself have a treat until you’ve set yourself so many questions to get right.
Check through your compendium that you’ve covered ALL the content and understand it BEFORE you get to the exam and find out you’ve missed something out. (Believe me as someone who missed 5 questions from her 50 questions she needed to learn for her German exam and these were the 5 that came up- it is really upsetting!)
If you learn nothing else- learn units and symbols. BUT PLEASE learn more than units and symbols. I think this tip is meant to inspire you that these are so important and can get you a long way!
Learn your prefixes!
During the Exam
Obviously you know- no secs in Physics, just stick to unit symbols and save all the problems of spelling.
Remember: SIG FIG, your final answer should be rounded up to the same number of significant figures as the LEAST significant measurement.
Make sure you see the words “end of question paper”. Don’t assume you’ve got to the end and there are no questions on the very last page!
Actually there are NO questions on the question paper anyway. All have command words, so learn these and what they mean. I’ll add the link in later.
“Show” questions – means show correct formula, working and numerical answer stated as given in the question. Your final statement should be what you’ve been asked to find.
Don’t leave anything blank! If you really don’t know, give it a go – you never know.
The questions in the exam sections (MC and then extended answers) are in approximately the same order as the Relationships Sheet.
LIST: given numbers with the correct symbols before doing a calculation. Or as we say IESSUU (information, Equation, Substitution, Solution, Units and Underline)
Start by writing down what the question has asked you to find. E.g. “Eh = ?”. Then write down the other quantities given. Only then choose a formula.
Substitute then rearrange.
Read all of the question, especially that bit you skipped over at the start.
Don’t forget units! It’s now worth at least 33% of a calculation!
Use common sense regarding “real life” things i.e. cars are unlikely to be going at 245 ms-1, a tennis player isn’t going to be serving the ball from 5m up etc etc
Sometimes multiple choice questions can be logic-ed through without any knowledge of physics. Physics and common sense are often the same thing.
If you can’t do part a) but could do part b) if you only knew part a), then make up an answer for part a) and put it in part a of the question and use that in part b).
This will do for now more to come as they arise……
Some practice notes from Mr Dawson from Wallace Hall Academy.
Thanks to the person on GUZLED who shared these. I’ve redone them so they don’t lose their formatting.https://mrsphysics.co.uk/n5/wp-content/uploads/2021/09/N5-Electrical-atoms.pptx
I can now upload ppp to mrsphysics, so here is one of the first. It is to cover section 9 and 10 of the outcomes. Thanks to the kind person who produced the stuff on A.C and D.C. I’ve been using it for years. Let me know if I’ve nicked it from you and I’ll add my grateful thanks.

Feeling brave- this isn’t as hard as it looks, but you can impress your friends and family.
Here are some additional notes that might help as you go through the materials. Check out the post on using your calculators to measure resistance (I’ll add the link here when I’ve found the post!)
Ring main Based on the SG course notes and not really in the N5 course, but it might give a little background to why when calculating the fuse rating for an appliance you use 240V and not the 230 V as stated.
EE1 – Electricity LOCKERBIE The old electricity notes (based on a colleagues work- thank you and I’ll find out who you are), these will be superceded when the document above is completed.
Elect & elect D&G Prob Book no answers These are some great little questions by Mr Belford formerly from Dumfries Academy, but some of the numbers are a little bit fictional!
For all Senior N4/N5 classes your assessment for the waves section will be on Tuesday AUGUST 29th 2017. It is expected that you will have completed the Outcome Questions, and marked these REVISE NOW!
