## Revision Plan

28/02/18. If you’re stuck inside- DON’T go on your X-boxes, PS4 or whatever the latest number try doing some timed papers.

To the student’s sister who needs the Quantity, Units, Symbols etc .I’ve uploaded the old pre-CfE version and you can just add the additional few. Check out Int1-AH many are relevant. Missing would be t’, l’ etc.

If there is a snow day tomorrow, use the time to look at the EMF material and the test will be as soon as we get back.

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. You don’t have to complete this in the same order, but it does give an indication of how much you need to cover in one week.

## Tips!

Here I will post a few tips and hints to remember when answering SQA Higher Papers, hopefully they’ll be quick, snappy and memorable. You’ve got the whole of the Scottish Physics Teachers’ Community Wisdom Below!

1. How to remember Cosmic Microwave Background Radiation (spell the whole lot not CMBR, as this isn’t a name) However, the way to remember CuMBRia.
2. Conservation of Momentum IN THE ABSENCE OF EXTERNAL FORCES, MOMENTUM BEFORE THE COLLISION IS EQUAL TO THE MOMENTUM AFTER THE COLLISION.
3. Obviously you know- no secs in Physics, just stick to unit symbols and save all the problems of spelling.
4. Fundamental Particles: Key point: it is not that they can be used to make bigger ‘things’, but rather that they are not made from smaller things.
5. Strong force (associated with the gluon) acts over a very short distance.
6. The gravitational force extends over very large/infinite distances.
7. Neutrons don’t carry/have (net) charge so cannot be accelerated/guided/ deflected by magnetic fields.
8. Remember: SIG FIG, your final answer should be rounded up to the same number of significant figures as the LEAST significant measurement.
9. Don’t forget to revise your uncertainties.
10. 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!
11. “Show” questions – means show correct formula, working and numerical answer stated as given in the question.
12. Don’t leave anything blank! If you really don’t know, give it a go – you never know.
13. The questions in the exam sections (MC and then extended answers) are in approximately the same order as the equation sheet.
14. LIST: given numbers with the correct symbols before doing a calculation. Or as we say IESSUU (information, Equation, Substitution, Solution, Units and Underline)
15. Substitute then rearrange.
16. Read all of the question, especially that bit you skipped over at the start.
17. Don’t forget units! It’s now worth at least 33% of a calculation!
18. This will do for now more to come as they arise……Check out the past paper marking instructions for do’s and  don’ts- its full of them in that second column!

Here are some top tips for Revision from Mr Dawson from Wallace Hall Academy- thanks

## End of the Summer Review

Well here is a little revision test to get you back in to the swing of things on the first lesson back.

Please complete these after the lesson so that we can move on. Remember I will only see you for a maximum of 116 more times before your exam!

I’ve done my homework, I hope you have too! It gets harder folks!

Answers and there is absolutely no point in checking these until after I’ve noted you’ve done them- yourself! If you do, you are not doing yourself any favours, as I can guarantee you will be the one to struggle at Higher as you always run to the answers in your study and you wont have developed the skills to pass your exam under the stressful conditions. It is important you are honest with your teacher and more importantly yourself!

## Revision Calendar

It is important that you realise that this year will go really quickly. As a part of your life it seems a long time, but trust me, it will go quicker than you can possibly imagine. That is why it is important to realise how little time you have to cover the whole course and revise it. If you thought N5 went fast just imagine that in half the time- because that is what Higher Physics will feel like!

For people in D&G I’ve made a D&G Calendar. For other Regions you’ll just need to adjust your holiday dates. From the first Monday you return to school there will be only 146 teaching days until Study Leave. Now if you think that you only get 5 periods a week, on 4 days per week that is a maximum of 117 times I’ll see you, you can start ticking them off if you dislike me that much. Take off all those days when you will be having trips, meetings, be at Sporting Events, doing prelims and the time to complete the course begins to look less plausible! We also have to fit in an Assignment.

I would therefore ask any student studying any subject not to waste any time in class and get as organised as possible. That means get into class, get out your stuff, and get going straight away. If there is a distraction then review your work, answer questions etc. Don’t waste a second!

# Revision plan

Click on the link above (Revision plan). This takes you to an EXCEL spreadsheet. I can add a pdf file if some of you can’t open this. Revision isn’t just about LEARNING the work. What will take more of your time are the other bits!

3. ### LEARN THE WORK.

You can and should be doing step one throughout the course. The better prepared you are as you go along the less time at the end of the course you will need for revision. Likewise with step 2. If you make sure you’ve fully understood each part of the work, then even if you’ve forgotten it, it should be easier to understand and grasp the second time around. If you pass on it and hope it will go away as you move through the course you’ll begin to have a fear of this section of the course and it will be harder to understand.

### So how do you use the Revision Plan?

• This can be used for just one subject but I think it puts it into perspective when you put all your calendar in one place. There are probably apps that will do the same thing, but I’m not there yet!
• Mark in the dates and times of Exams (whether prelims or final exams). I’ve put in the Physics Exam Date for you and a counter has been added to the N5 Home Page. I’d check this often just to remind you how far we are through the course.
• Shade in the dates and times of commitments, such as parties, trips away, days off (birthdays when you’ll have all those presents to open) etc.
• Make a list of topics to cover for each subject; the Physics one is done for you. But remember revision is about CHECKING, UNDERSTANDING and LEARNING so all three of those have to be allocated time.
• Calculate how many hours you have available and how much time you will allocate to each subject and each topic within that subject.
• Decide on the order in which to tackle your subjects. Don’t tackle the easy subjects first as you’ll never get on to the harder ones! It is best to start revising the hard subjects and topics as these will take you more time to understand and learn
• Draft your revision timetable.
• Leave one or two revision slots free each week for extra revision or difficult topics.
• BE SURE TO LEAVE YOURSELF SOME TIME FOR REST AND FUN ACTIVITIES including being healthy.
• Don’t spend so long producing a beautiful revision timetable so that there is not enough time to revise.

## Questions on Key Areas

Grateful to Mr N Forwood, one of the IoP Coordinators for getting this done. He has gone through past papers and written out which questions are attached to which key area in the work. Hope it helps with your revision.

## Command words in Higher exam papers!

Here is a table showing some of the command words that are used in the exams. I will give examples later. It is important to answer the correct command word in the right way or you are likely to not be awarded marks.

Do go through past paper questions and get examples of the different command words and then look at the marking instructions and see how they are answered.

Below I have taken examples of the command words contained in the 2015 Revised Higher paper, and given the expected response. I will continue to adjust this as I have time, for now just look over what is expected. You might need to refer to the paper to make sense of the question.

`obviously I need a little practice at learning how to format tables, I'll work on that, but I've not been doing this a year yet!`
 Use a highlighter to underline the command words Response examples based on the 2015 Revised Higher Paper (2·2 × 10−25 /1·673 × 10−27 =) 134 (½) (Higgs boson is) 2 orders of magnitude bigger (½) If mass of neutron (1·675 × 10−27) is used, treat as wrong physics – award zero marks. 134 times bigger, (½) only Compare the mass of the Higgs boson with the mass of a proton in terms of orders of magnitude. (when a) current (½) passes through a p-n junction (½) photons are emitted (1) Describe how an LED operates. vh = 11·6 cos 40 = 8·9 m s−1 (1) (accept 8·886, 8·89, 9 not 9·0) Calculate the horizontal component of the initial velocity of the shot. · (total energy remains the same) · the greater the angle the more energy used to lift the put to a greater height before release · less energy available to convert to Ek (½) · Kinetic energy is less (½) This statement is required before ANY marks can be awarded. Using information from the graph, explain the effect of increasing the angle of projection on the kinetic energy of the shot at release. v = 11·6 m s−1 photon State the release speed of the shot at this angle. Name the boson associated with the electromagnetic force. (an extra particle) the (anti)neutrino (1) would have (some kinetic) energy (1) From this evidence, what conclusion have particle physicists drawn about what happens in beta decay? Justify your answer. (Constant speed  Þ ) upward force = weight (½) 3 Tcos20 = 1380 (1½) T = 490 (N) If 490N not stated then (1½ max) Show that the tension in each cord is 490 N at this instant. A physics student notices that the digital clock in the family car loses one minute every six months. The student states “This must be due to time dilation as the car is driven at motorway speeds for much of the time.” Use your knowledge of physics to comment on the student’s statement.

On a similar matter, it is important that you don’t use the wrong adverb for a quantity.

Don’t use the terms quicker, slower, faster, for words such as time, acceleration, velocity.

Use terms longer, shorter for time greater than or less than for acceleration and velocity.

To say quicker time, you are talking about relativity! You want to say that the time will be less to do the same action.

…And here are my command words. Do your best, revise as hard as you can. This will be with you for the rest of your life.

TermDefinition
absolute refractive indexthe absolute refractive index (or just the refractive index), n , of a medium is the ratio of the speed of light in a vacuum to the speed of light in the material. (also the ratio of the wavelength of light in a vacuum to the wavelength of light in the medium)
angle of incidencethe angle between the incident ray and the normal.
angle of refractionthe angle between the refracted ray and the normal.
atomic mass units (u)by definition one twelfth of the mass of a carbon-12 nucleus.
atomic numberthe number of protons in an atomic nucleus. It is this number that determines the element and its properties.
binding energythe energy needed to split a nucleus into its separate nucleons (not on the CfE Higher course)
chain reactionwhen a nucleus undergoes fission it releases neutrons that can go on to cause further fission reactions by interactions with other nuclei. If there is a sufficient concentration of suitable nuclei, the process becomes self-sustaining.
coherent wavescoherent waves are waves that have the same frequency, speed and have a constant phase relationship.
collimatorpart of a spectrometer that is used to produce a parallel beam of light.
constructive interferencewhen waves arrive at a point in phase or crest meets a crest and trough meets a trough resulting in a wave of larger amplitude than the individual waves.
critical anglethe angle above which total internal reflections occurs. Or, the maximum value of the angle between the normal and the ray in glass, θ glass, for which refraction can occur.
destructive interferencewhen waves arrive at a point in out of phase or crest meets a trough resulting in a wave of smaller amplitudeas the waves cancel out.
diffractionan effect that causes waves to bend as they go past the end of an obstacle or through a small gap in a barrier.
dispersionthe process of splitting up light into its constituent colours, this can be done with a prism and white light.
electromagnetic wavesthe spectrum of waves that includes radio, visible light, X-rays etc which all have no mass and travel at the speed of light in a vacuum.
excited stateany atomic energy level higher than the ground state.
ferromagneticmaterials in which the magnetic fields of the atoms line up parallel to each other in regions known as magnetic domains.
fissionthe splitting of a large atomic nucleus into smaller fragments, with the resultant release of excess energy.
gold leaf electroscopedevice used to measure small amounts of charge.
gratinga transparent slide of glass or plastic that has a very large number of equally spaced grooves machined on to its surface. Each groove acts as a source for coherent beams of light.
ground statethe lowest energy level of an atom where an electron has the lowest energy level.
induced fissionthe deliberate splitting of a large nucleus caused by the collision of the nucleus with a neutron.
interferencea phenomenon in which two waves superpose to form a resultant wave of greater, lower, or the same amplitude.
ionisation levelthe energy level at which an electron can break free from an atom.
irradiancethe power per unit area of radiation incident on a surface.
isotopesdifferent forms of the same element. The isotopes of an element contain the same number of protons but have different numbers of neutrons. (Many isotopes are unstable and can emit nuclear radiation)
line absorption spectruma spectrum that consists of narrow dark lines across an otherwise continuous spectrum.
line emission spectruma spectrum consisting of narrow lines of light, the position of which depend on the substances producing the light.
magnetic domainsregions in a ferromagnetic material where the atoms are aligned with their magnetic fields parallel to each other.
magnetic fielda magnetic field is a region in which a moving charge experiences a magnetic force.
magnetic polesone way of describing the magnetic effect, especially with permanent magnets. There are two types of magnetic poles - north and south. Opposite poles attract, like poles repel.
mass defect (do not confuse with mass difference)the difference between the mass of a nucleus and the total mass of an  equal number of individual nucleons.
mass differencethe difference in mass between the reactants and products in a nuclear reaction. The resulting mass difference is converted to energy according to the equation E=mc 2 .
mass numberthe total number of nucleons (protons and neutrons) in the nucleus of an atom.
monochromaticradiation consisting of a single frequency.
monochromatic lightlight of one wavelength (and therefore one colour)
normala line drawn at right angles to a surface or the boundary between two different media
nucleonthe general term for protons and neutrons (contained in the nucleus).
nuclidethe nuclei of one particular isotope. These nuclei all have the same atomic number and mass number.
path differencethe difference in path lengths of two sets of waves.

photocathodethe terminal from which electrons will be emitted due to the photoelectric effect.
photoelectric effectthe emission of electrons from a metal due to the effect of electromagnetic radiation.
photoelectronsfree electrons produced by the photoelectric effect
photoemissionthe emission of electrons from a material caused by light shining on it.
photonthe particle of electromagnetic radiation.
potential differencethe potential difference between two points is a measure of the work done in moving one coulomb of charge between the two points.
principle of reversibilitythe principle of reversibility states that a ray of light will follow the same path in the opposite direction when it is reversed.
prisma prism is a transparent optical element with flat, polished surfaces that refract light. A dispersive prism can be used to break light up into its constituent spectral colours.
quantaa "packet" certain amount, often referring to the energy of photons.
radioactive decay seriesa chain of radioactive decays as a radioactive element changes to eventually become a stable, non-radioactive element.
refractionrefraction occurs when a wave goes from one medium into another. When a wave is refracted, its speed and wavelength change; its frequency remains constant; its direction sometimes changes.
spectrometeran instrument that can make precise measurements of the spectra produced by different light sources.
spontaneous fissionthe random splitting of a large atomic nucleus due to the internal processes within the nucleus. (it does not require neutrons to cause the reaction and so is not of use in a nuclear reactor).
stopping potentialthe minimum voltage required to reduce photoelectric current to zero.
telescopethe part of a spectrometer through which the spectrum is viewed.
threshold frequencythe minimum frequency of electromagnetic radiation that will cause photoemission for a particular substance.
total internal reflectionwhen a ray of light travelling in a more dense substance meets a boundary with a less dense substance at an angle greater than the critical angle, the ray is not refracted but is all reflected inside the more dense substance.
turntablethe stage or platform of a spectrometer on which the grating or prism sits. The turntable has an angular scale on it to allow measurements to be made.
work functionthe minimum energy required to cause photoemission from a substance.

## WORKSHOP

### WORKSHOP for HIGHER 2019-

https://www.sqa.org.uk/sqa/files_ccc/ExamTimetable2018.pdf

Create your own SQA timetable when you click on the link below https://www.sqa.org.uk/sqa/41619.2558.html

Here are a few little gems that we will discuss at the workshop. If you can’t make it then you ought to be able to work through the material yourself. I hope you find this material useful. I will stick up the agenda as soon as. I will also publish a sheet on the question grid against past papers. Best wishes for your revision

The word document. Lots to digest here, so you might want to look over it prior to the workshop. Don’t do it all as I’ll have nothing to go through with you for the workshop.

Please note the workshop is not a place for you to learn, but a place for you to get practice and a few exam techniques!
