Someone has just twitted about this brilliant animation. I hope it makes you realise the consequences of different gravitational field strengths.
Let’s start with a song!
and if you like that one, then this is Physics legend
this has got lots more information on the EM Spectrum

Waves Summary Notes
These are waves summary notes I’ve produced. Hope you like them. I’d appreciate someone telling me if a photodiode can detect gamma radiation!
Revision Mind Map
This is part of a series of brilliant Mind Maps made by Miss Milner for the N5 Physics Course. I’ve broken it up into sections so here are the waves mind maps!
Here are a list of current wave resources. I will add more as I go through them. Thanks to other schools if you have kindly supplied material. I really appreciate it as do my students.
This is a pdf of the power point that I a using
waves-summary-notes-gairloch1 Some of these notes are for National 4, use with the content statements so you don’t spend too long learning the National 4 work.
vflambda-vdt This starts with a practical model that you can complete in class using the Virtual Physics/ Flash Learning. It then shows how v=fλ is equivalent to v=d/t. Finally some questions will let you practise what you know.
The audio can be turned off it is annoys. Here is the Virtual converted to an mp4 if I can get it to work. If people comment and find them useful I can do the rest.
PLEASE NOTE: I KNOW I HAVE A FEW BLOOPERS IN HERE. I’VE GOT TO FIND AN EDITING PACKAGE AND FIND TIME TO USE IT.
This is the main Radiation post. Start here!
Here’s the video
Thanks to Miss Horn for the Radiation Notes. Worked Answers to follow.
Thanks to Miss Horn who started these off
Fusion is the process when two SMALL NUCLEI join to form a LARGER NUCLEI with the production of ENERGY
Fission is the process when two large nuclei split to form two smaller nuclei with the production of energy. This can occur spontaneously or due to a collision with a neutron. Often extra neutrons are produced.
When neutrons split nuclei by fission and extra neutrons are produced which can split further nuclei. Large quantities of energy are produced.
Reducing exposure to ionising radiation.
There are 3 groups of category to reduce harm caused by radiation:
Monitor includes things like wearing radiation badges or EPUs, timing how long you are exposed to radiation, checking with radiation counters any contamination on clothes.
Shielding is placing layers of absorbers between you and the source, BEWARE, goggles and a lab coat are great at protecting against alpha but have no effect on gamma. Only thick layers of lead would offer protection against gamma.
Distance. Radiation obeys the inverse square law, as you double the distance from a source the level you are exposed to decreases by ¼ . Using tongs is an effective method of keeping your distance from a source.

Here are some videos and powerpoint shows that I’ve made for the NPA but the outcomes are the same as those in N5 Physics. Thanks to John Sharkey for the use of the Virtual Flash Physics (Int 2) and to Julian Hamm of furryelephant for the animations of ionising an atom.
If you haven’t done much Chemistry and you don’t know the process of how chemical elements are described, I suggest you check out the video below.
NB In the video above I know totally that photographs were taken well before 1896, the first being taken in 1826. Henri Becquerel discovered that Uranium, a naturally radioactive element fogs photographic film.
Using John Sharkey’s Virtual Animations I complete the Half Life of Protactinium 234. The sound needs to be turned down after the first 60 s
This is the draft copy of the Half Life Experiment until I can take out all the noise. I might redo it a third time!
The first one is from the Flash Animations
This one below is from the Int 2 Virtual Physics. No sound, but a few notifications for Teams!
I hope that I am not breaking any rules, but these great resources no longer appear to be online. Can’t believe they are 20 years old!
The first photos show the background count rate, a reading of counts taken over a 1 minute period. The source is then taken out at 9:00 am and a count taken between 9:00 and 9:01, readings are then taken every 15 mins.
|Time & Counter||Close up ratemeter|
| Photo missing
count rate= 570

Here is an experiment
Various materials of the same mass (500g) are crushed, placed in a boil in the bag bag and placed in boiling water until they have reached equilibrium. They are they removed rapidly and placed into a beaker with a known volume of water and a known temperature. The highest temperature they reach is recorded.
Describe what will happen to the temperature of the beakers when the bags are placed in them.
Why are the bags left in the boiling water for a long time?
Why must you be quick moving the bags into the beakers of water at room temperature?
What would happen if water got trapped in the top of the bag when moving them?
Why are the materials crushed and not a solid lump?
Could this be used to find a value for the specific heat capacity? If so, how.
At last I’ve completed the LOQ. I am sure I’ll find mistakes when I produce the answers. I will get those done a.s.a.p, but they take a lot longer to type up than write up.
When completing these questions there is no point in just going straight to the answers, it wont teach you anything. Use the answers after you’ve completed what you can do and had a good guess at what you can’t. Mark in green anything you’ve had to look up.
Complete book of outcome questions
Properties of Matter
This also contains some bonus material on problem solving questions. You’ll find these in every paper.
This contains the N5 Physics Self Assessment Answers for each unit. Revise with these or use as homework
There is absolutely no point in just copying out the answers. There is an important requirement in checking your answers carefully to ensure you haven’t made a mistake and that you’ve understood the course specifications and the learning outcomes.
Only check over the answer when you’ve completed a section and mark them in green pen.
Advice from the SQA
From the Understanding Standards Meeting I went to Physics teachers were advised to tell their students NOT to add in the rearranging line for their calculations. Just do the formula, substitution and final line. For some of you this will involve too many steps so you might want to cross out any middle lines. I’ve shown mine in these answers to hopefully give you more help as to how to get to the answer.
All Units (the maths bit)
Finally finished, but I’ll need to edit out the duplicates but I’ll do that with the updated booklet so the numbers match. (updated 22nd June 2020) Not sure when they will get done, it might be a 2021 version
Properties of Matter
Radioactivity & Variables Questions
Please if you find mistakes in my answers please add a comment below.
I will now need to go through and make a 2021 booklet of questions and answers with the corrections. This is a long slow process! I hope you find them useful, then it will have all been worthwhile…… Now I need to start the Higher ones!
Here are the Waves Learning outcome questions which will help you through your revision. They can also be found in the Learning outcome section in the Course Material drop down menu. Answers are on here too, but copying from the answers is a pointless activity. Hopefully by completing all of these questions you will have produced an excellent set of revision notes from which to revise.
You can always use these in electronic version to answer the questions but DON’T think you’ll produce one set between you and copy!

Electromagnetic Wave Practicals
One of the uses of UV radiation is a security feature of bank notes. Shining UV radiation on to the bank note causes them to fluoresce (the atoms in the material take in the UV radiation and re-emits it as light which we can see)
Look at how advanced the fluorescing shapes and colours are.
IR cameras are used by the police to track for criminals at night but they are also really useful to the fire brigade at finding people in smoked filled buildings, you can’t hide behind a bin bag and even a hand print can leave a “heat print”.
Did you know you can be on the radio? Not very musical but it can drown out Radio Scotland.
The electromagnetic (em) spectrum is a collection of transverse waves that all travel at the same speed in air, the speed of light, 300 000 000 m/s. (equivalent to 7.5 times round the Earth every second)
One of the waves is VISIBLE LIGHT
Others are RADIO & TV, MICROWAVE.
The others are INFRA-RED, ULTRA VIOLET, X-RAYS, GAMMA WAVES.
The only difference between each of these waves is their wavelength or frequency. They all fit the formula
Speed= frequency × wavelength
The order is important and to remember it use the following rhyme!
Randy Radio & TV
Period, T, is the time for one wave to pass a point and is measured in seconds.
Frequency, f is the number of waves being produced or passing a point per second. Frequency is measured in Hertz (Hz)
Here are lots of resources for you to check and practice. My utmost apologies if I have not credited people for sending this material. As soon as I know who you are I will thank you personally.
REVISION GAMES FOR WAVES
A couple of songs for this unit
This is the updated version of the Dynamics booklet, updated to match the 2017 SQA changes.
This one is a joint effort by Miss Horn and Mrs Physics with formatting help from Mr Risbridger.
New in by Melanie Ehsan, with thanks to eSgoil (who provide lots of online materials), the first of a collection of mindmaps.
The materials below I’ve just uploaded from my Intermediate 2 folder and thought some of this might be useful. It’s a quick upload and I’ll sort it out when the rest of the development work is completed (hahaha). Currently I’ve a prelim to write and get copied for two weeks time.
Here are some practice questions with worked answers and 6 to a page diagram of the sky diving graph
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.
