Introduction to the Physics Dept

Welcome to National 5 Physics.

We hope you will enjoy the experience of learning Physics over the next year. This information gives you a clear idea of what you’ll complete during the course.

SURVIVING THE COURSE.

1. The structure of the Course.

The first thing to understand if you are to achieve your best in Physics at National 5, is to have a clear understanding of how the course is run. The course is made up of several parts; divided up in several ways.

There are six units and the Assignment (which changed for the session 2017-18):

  1. Waves
  2. Radiation
  3. Dynamics
  4. Space
  5. Electricity
  6. Properties of Matter
  7. Assignment (20% of the course covered in class but marked externally)

The topics covered in each unit are given below:

  1. Dynamics – vectors and scalars; velocity–time graphs; acceleration; Newton’s laws; energy; projectile motion.
  2. Space – space exploration; cosmology.
  3. Electricity-electrical charge carriers; potential difference (voltage); Ohm’s law; practical electrical and electronic circuits; electrical power.
  4. Properties of matter –specific heat capacity; specific latent heat; gas laws and the kinetic model.
  5. Waves – the topics covered are: wave parameters and behaviours; electromagnetic spectrum; refraction of light.
  6. Radiation –is nuclear radiation.

Eventually, you will have a set of Learning Outcome Questions to complete, containing what you have to know for the exam.

The SQA states that the Assignment and Exam will test:

  • knowledge and understanding of physics by making accurate statements
  • knowledge and understanding of physics by describing information and providing explanations and integrating knowledge
  • applying physics knowledge to new situations, interpreting information and solving problems
  • planning or designing experiments to test given hypotheses or to illustrate particular effects, including safety measures
  • carrying out experimental procedures safely
  • selecting information from a variety of sources
  • presenting information appropriately in a variety of forms
  • processing information (using calculations and units, where appropriate)
  • making predictions based on evidence/information
  • drawing valid conclusions and giving explanations supported by evidence/justification
  • evaluating experimental procedures
  • suggesting improvements to experiments/practical investigations
  • communicating findings/information

In summary the course will be completed in the following order:

  • Maths and Intro
  • Waves
  • Dynamics
  • Radiation or Electricity
  • Electricity or Radiation
  • Assignment
  • Properties of Matter
  • Space
  • The exam

2. The Need to Know Booklet and organising you work.

Currently, all the information you need to pass the exam is highlighted in the Compendium. Check this every lesson and note your progress through the course, ensure you understand what you need to know.

Eventually, we hope to produce a set of Learning Outcome Questions, the answers will provide you with a perfect set of revision notes. These should be answered clearly and concisely in your Notes. Either copy out each question or print the questions and stick these in your notes. Then others can test you.  Alternatively, you can make these into flash cards.

Another hint is to make your work as colourful and neat as possible. This is going to form your most important work so take care of it. If it is bright, colourful, well presented and laid out it will be easy to revise from. Hand in your notes regularly for checking.

At the back of the notes jotter keep a list of all of your quantities etc. in a table like the one below. These are also in the compendium.

Your formulae should also be in the notes section. Keep the list up to date! Each time that you learn a new formula put this in your notes. Make sure you include units, symbols and the meaning of each letter. Check that you can rearrange the formula to find any missing quantity.

The work that you do in class should usually be written in your class work jotter. Date all work and record a title for each activity. Sometimes notes will go straight into your notes jotter, so you must have this with you every lesson.

You will also keep a profile of your performance in your profile section. This should start with your contract (see the end of this post), profile of you and an introduction About Yourself. This will help us to gain a good understanding of how you function. You will need to set targets each month on how you can improve your performance or maintain your performance at the current level, if it really is the best you can deliver. We will also try to tailor some of the tasks to items that interest you and assist you in meeting these targets. All progress that you make should be recorded in this jotter and it would be helpful to discuss these targets with folk at home. Include a progress bullseye chart each month like the one below, electronic copies can be downloaded from the links below too.

bullseye

bullseye    

The main reason we use the pupil profile is to give you the chance to discuss with your teacher, at your leisure, any concerns, worries or problems you might have. This is not to prevent you from talking directly to your teacher, but it gives you the opportunity to enter into a dialogue with your teacher at a time that is convenient to you both. This will become part of your homework on a monthly basis. Your pupil profiles should be handed in on the first lesson of every month. Get into the routine of handing this in. Please mark in your student planners that this homework is due on the first Physics lesson of every month. Obviously, if you wish to hand this in more often you may do so, in fact hand this in whenever you have a concern. Your teacher will record and note any concerns and comments and deal with these as soon as possible. This may be in the form of additional work, additional help or additional resources.  But don’t forget your pupil profiles can also tell us when you’re really happy with the course, enjoying it and feel that you are making good progress. Don’t rush your response, but engage with how you can improve and what areas you feel are your weakest and strongest.

3. Follow the Rules & Routines & Bring Equipment

The five rules of the Physics Department are for pupils follow to ensure a pleasant and safe environment.

  1. Follow the teacher’s instructions.
  2. Raise your hand, and wait for permission before speaking.
  3. Allow people to get on with their work.
  4. Follow the laboratory rules
  5. No put downs. (or only say positive things about people).

Remember Science is about trial and error and looking for ways to fix mistakes, what a better example for life!

ROUTINES

In addition to the core rules the following routines are expected of pupils during their time in this department. Pupils should:

  1. Enter the room quietly, calmly and on time;
  2. Come prepared for the work with jotters and pen or pencil etc.;
  3. Complete all homework and hand it in on time;
  4. Not deface jotters, desks folders, etc.;
  5. Pay attention;
  6. At the end of a lesson, when told to do so, pack away quietly, place stools under the desk and leave in an orderly manner.

3.  Homework and Review

You will be expected to complete all the homework set and hand it in on time. We will contact parents/carers if we think you are not completing this vital part of the course. We do not issue homework because we want you to spend all your life working, but because it gives you the opportunity to consolidate the work completed in class. It has been proved that students who complete homework do better in their exams.

 4. The Timeline

You will be issued with a timeline. This may be on a monthly, weekly or termly basis. This will show you what homework you will have to do, where on the course you are and when assessment dates are likely to be. We may have to update this through the year but it should be used to plan study and work. Don’t waste it, use it!

 5. ASK!

If you do not understand any aspect of the course or work and you have read through the material at home then ask. Both members of the Department (Mrs Physics and Ms Horn) are willing to help you with your work.

 6. Equipment

This is a list of the equipment you need to bring to Physics

  • Pen
  • Pencil
  • Ruler (30 cm)
  • Eraser
  • Protractor or angle measurer.
  • Scientific calculator, nothing fancy but it must be capable of doing scientific functions. Most pupils find it easier to use a Casio DAL, S-VPAM calculator, particularly the Casio FX83 or Casio FX85. With these calculators you enter the numbers into the calculator in the manner in which they are written. There is a post in the maths section giving you some example of how to work your calculator and I’ll add a few more hints later in the year.

Pupils will be issued with

  • A classwork jotter for practice and results
  • A notes jotter
  • A homework / profile jotter
  • An A5 Content booklet containing the Content Requirements, Relationships’ Sheet, Periodic Table and a few maths hints. This should be brought to every lesson and used every night to check content coverage and for revision and review. This can be kept at the end of the course as it will be covered in student writing.
  • Students will receive topic booklets with content and questions. These should be returned at the end of the course.

7. Take Responsibility for your Learning

Sometimes there may be a distraction in the classroom that is out of our control. Make sure that you use your time wisely if there is a distraction. Check and complete one or more of the activities listed below.

  • Finish off the work that has been set.
  • Complete Learning Outcome Questions/ Summary of content statements.
  • Check off the content covered in the Vital Booklet (good name needed)
  • Write out a summary of what you have been doing.
  • Read through the work that we have been covering.
  • Read through the next section of work to prepare.
  • Revise/ Learn your formulae
  • Produce a revision test for the class.

Your work is in your hands. This is time that can be used or abused. If you abuse your time now you will have to use your free time later. SPEND YOUR TIME WELL.

8. Layout for Tackling Mathematical Problems

Always set out maths problems using the structure given below. It may seem to take longer but it will save time in the long run as it makes the question clearer.

USE IESSUU

http://www.youtube.com/watch?v=u7akhlAS5Ck

  1. Information– Summarise the question by writing down what you know from the information given. Use the letter that goes with the quantity and this will help you be able to work out the correct formula
  2. Equation – write down the equation as it occurs in the data sheet. Do not attempt to rearrange it before substituting.
  3. Substitution – put the numbers into the equation as they appear in the formula
  4. Solution – work out the answer. You are ALWAYS allowed to use a calculator
  5. Units– you will need to use the correct units so will need to learn these. No or wrong units no mark for the answer
  6. Underline – underline with 2 lines the answer to make it clear what is your final answer.

In short:

  1. (Information)- Summarise the question.
  2. Change any units that are not standard.
  3. (Equation) -Write out the formula.
  4. (Substitution) -Put the numbers in.
  5. Use the magic triangle to rearrange the formula, only if you must!
  6. (Solution)- Work out the answer.
  7. Write out the answer, but not to too many sig fig.
  8. (Units) -Add units to your answer.
  9. (Underline) Underline the answer.

9. Revising The Syllabus

REVISING- Here are some really important ideas to help you with your revision (which shouldn’t just take place the night before a test but should be an ongoing process).

Find out:

  • Make a Revision Calendar (I’ve made one for you Click Here! The instructions can be found in the Revision section)
  • Stick a large calendar next to where you study.
  • Mark in the dates and times of Exams (whether prelims or final exams). A countdown timer is on the N5 Home Page.
  • Shade in the dates and times of other commitments.
  • Make a list of topics to cover for each subject.
  • Calculate how many hours you have available and how much time you will allocate to each 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 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.
Working in Revision Groups
This can be useful but:
  • Discipline is needed
  • Decide before you meet on the topic that you’ll cover e.g. prepare revision cards or answer past paper questions.
  • Teach each other a topic
  • Take an ACTIVE APPROACH to your Revision
  • Talking with others about what to revise can lessen the anxiety.
  • Before starting a Session decide HOW  and WHAT to revise 

DON’T JUST SIT THERE READING AND RE-READING YOUR NOTES.

A STEP BY STEP REVISION STRATEGY

  • FIND A FOCUS
  • MAKE REVISION CARDS
  • TEST YOURSELF
  • LEARN IT!
  • TEST YOURSELF
  • CHECK IT!

10. Relax

Believe it or not we also expect you to make sure you relax. Relaxation should be in proportion. Too much and you won’t finish the work, too little and you will not function properly; balance is important. Make sure that your relaxation includes plenty of exercise and fresh air. Don’t just vegetate in front of something electrical.

Now you have your survival guide may we wish you all the best and hope you perform Physics to the best of your ability, whatever that standard!

Remember we are a TEAM! It is not YOU ALONE! It will be most effective if YOU, ME and PEOPLE FROM HOME can all work together to support you through the next nine months. We each have a role to play. I need to explain what we need to do in the best way I can, and ensure you know the course content. Your role is to listen well in class, learn what you are taught, ask if you have not understood what you’ve been taught and review and revise little and often. Tell me if you are finding the work hard so that I can give you additional support. People at home are there to support and encourage you in your work and if possible test you on your learning, (provided you’ve laid it out as well as possible).

After a Test

It is important that you review your performance after a test. One way to do that is through a Thinking about Revising Sheet.

Definitions for Space

These are some very basic definitions for the Space Topic

Universe: Sum total of everything that exists.
Galaxy: A basic building block of the universe that includes stars, star clusters, clouds of gas, dust and interstellar molecules.
Solar System: Is one or more suns surrounded by orbiting planets. Our solar system is composed of the sun, 9 known planets and at least 44 moons, thousands of “minor planets” (asteroids) meteors and perhaps billions of comets.
Sun: Dominant member of a solar system accounts 99% of the mass of the solar system. The sun is a giant star it produces heat and light. A big ball of plasma
Star: Principle components of galaxies. Living stars emit radiation across the electromagnetic spectrum.  Peak depends on the heat of the surface.
Planet: A relatively large body rotating in an elliptical orbit around a sun.
Moon: A natural satellite of a planet i.e. rotates around a planet. Moons do not produce their own light.
Mass: Mass is a measure of the amount of matter in an object. It is measured in kilograms. Wherever you go your mass stays the same.
Weight: Weight is the force of gravity acting on an object pulling it towards the centre of the Earth or any other large mass. Weight is a force and so is measured in Newtons. The weight of an object varies depending on where you are (which planet etc and how far you are from it’s surface, the further away from the surface the smaller is your weight)..
gravitational field strength : gravitational field strength, g, is the weight per unit mass. It is measured in Newtons per kilogram. It is the force of gravity or pull on each kilogram of mass.
Inertia: Inertia is the property of an object which makes it hard to get an object to move, or to stop a moving object. Inertia varies with mass, so the bigger your mass the bigger your inertia..
Acceleration due to gravity: All objects will acceleration due to gravity. On the Earth, close to the surface objects accelerate at 9.8 ms-2 .
Light year: The distance light travels in a year equivalent to 9.46 .
Light

Light does not travel at an infinite speed. It takes time to travel. It is so fast that we do not usually notice, although out in space the distances involved are so big that light takes a reasonable amount of time to reach us.

Light travels at: 3 × 108 ms -1

Given that it takes 8 minutes for light to get from the sun, how far is it away is it from the Earth?

8 × 60  = number of seconds in minutes  = 480s

Each second light travels 3 × 108m

d= v t

d= 3 × 108   × 480  = 1.44 ×1011m

How far does light travel in one year?

1 year  = 365days

365days  × 24 = 8760 hours

8760 ×60 × 60  = 31536000s in one year

Distance travelled in 1 year, d = v t

d = 3 × 108 × 31536000     = 9.46 × 1015 m in one year = one light year

The light year (ly) is the distance light travels in one year.

Light travels at 3 × 108 ms-1

Source Time taken for light

to reach us

Distance (m) Working
Moon 1.2 s 3.6 × 108 1.2 × 3 × 108
Sun 8 min 1.44 × 1011 480 × 3 × 108
Next nearest Star 4.3 y 4.07 × 1016 4.3 × 9.46 × 1015
Other side of galaxy 100 000 y 9.46 × 1020 100 000 × 9.46 × 1015
Andromeda galaxy 2 200 000 yr 2.08 × 1022 2 200 000 × 9.46 × 1015
Continuous Spectra

Many light sources produce a continuous spectrum containing all the wavelengths of visible light, e.g. an ordinary light bulb.

Line Spectra.

Some light sources emit only some wavelengths. They produce a line spectrum. Each line corresponds to a particular wavelength.

Each chemical element has its own line spectrum pattern(so it is like a finger print!)

Line spectra can be varied using a spectro-scope in the classroom.

Line spectra are used to tell us about the chemical composition of the stars.

 

 

Half Life

Half Life

Half Life is the time for the activity to halve.

Time for activity to (decrease by) half
or  time for half the nuclei to decay

 (It is measured in units of time, e.g seconds, minutes, days, years, millions of years!)

Note the SQA do NOT accept: Time for radiation/radioactivity/ count rate to half

Experiment to Measure Half Life

The activity of a radioactive source decreases time. However the rate of decrease slows with time. Because of this, and because the decay of individual atoms is random and unpredictable, theoretically a radioactive source will never completely lose all of its activity. The time taken for half of the atoms in a radioactive sample to decay is a constant for that source called the half-life of the source. So the half-life of a radioactive source is the time period during which the activity of the source falls to half of its original value. The half-life of some sources is as low as a fraction of a second; for others it is many thousands of years.

Finding the half-life of a radioactive source

Apparatus: Geiger-Muller tube, Scaler counter or ratemeter, Source (eg.sealed protactinium-234 radioactive source and drip tray).

 half-life-exptInstructions:

  • Use the Geiger-Muller tube and scaler counter to measure the back­ground count rate.
  • Record this value.
  • Set up the apparatus shown in the diagram.
  • Measure and record values of count rate and time interval for a suit­able time period.
  • Correct all your measurements for background by taking the background count off all other measured count rates..
  • Plot a graph of COUNT RATE or ACTIVITY against TIME.
  • Find the half life from the graph

half-life-graph

Half life and safety

To measure the half-life of a radioactive source, the level of the background radiation is first measured. Then the count rate with the radioactive source present is measured over a suitable period of time using a suitable detector such as a Geiger-Muller tube connected to a scaler. A graph of the count rate (with the source present), corrected for background radiation, is plotted.A suitable count rate value is chosen, say 80 counts per minute, and the time at which the source had this count rate, t1, is marked as above. In a similar way the time t2 at which the count rate is half the previous value, 40 counts per minute, is found. The half-life of the source is the time period t2 -t1. Any starting value can be chosen, the time period for the count rate to halve in value will always be the same.

EXAMPLE

In six years, the activity of a radioactive isotope drops from 200 kBq to 25kBq. Calculate the half-life of the isotope.

SOLUTION: original activity = 200 kBq 

Activity after 1 half-life = ½ ×200 kBq = 100 kBq

Activity after 2 half-lives = ½ × 100 kBq = 50 kBq

Activity after 3 half-lives = ½ × 50kBq = 25 kBq

 

So 6 years represents 3 half-lives, thus one half-life is 2 years.

Safety with radiation

There are several safety precautions that must be taken when handling radioactive substances.

  • Always handle radioactive substances with forceps. Do not use bare hands.
  • Never point radioactive substances at anyone.
  • Never bring radioactive substances close to your face, particularly your eyes.
  • Wash hands thoroughly after using radioactive substances especially after using open sources or radioactive rock samples.
  • Unauthorised people must not be allowed to handle radioactive substances. In particular, in the United Kingdom, no one under 16 years of age may handle radioactive substances.

In addition there are several safety precautions relating to the storage and monitoring of radioactive substances.

  • Always store radioactive substances in suitable lead-lined containers.
  • As soon as source has been used, return it to its safe storage container, to avoid unnecessary contamination.
  • Keep a record of the use of all radioactive sources.

The equivalent dose received by people can be reduced by three methods:

  • shielding;
  • limiting the time of exposure;
  • increasing the distance from the source.

Stay safe and keep under your annual dose of 2.2 mSv!
