A collection of Resources for colour and light. I will source contributors and add a reference section at the end. Thanks to all those people who supplied resources.
Some people are unfortunate and have colour deficiency. This is usually a genetic condition.
The different types are protanomaly, which is a reduced sensitivity to red light, deuteranomaly which is a reduced sensitivity to green light (the most common form of colour blindness) and tritanomaly which is a reduced sensitivity to blue light (extremely rare).
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
v=f λ
The order is important and to remember it use the following rhyme!

Xylophone X-rays
Gunships Gamma
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.
Keith Johnson has written an amazing book which is being updated regularly. You can access free powerpoints here. I really hope that he doesn’t mind me reproducing one of them here, but pop along there for a whole list of useful powerpoints for all your classes, or for students to brush up on lots of Scientific skills.
Then answer the questions below, complete the WAVES section to the end of section 19 inclusive.
Week 4 due date 08/01/20
Dynamics Section (section 1) Answer the Introduction part of Dynamics and then answer all of the questions in each of the following sections 1.1, 1.2, 1.4, 1.5, 1.6, 1.8
Hooray! we’re back to doing our heat unit with a few minor changes. Let’s see if I can upload the ppp here! They’re rather large. No idea why I’ve large gaps. Originally these showed the pdf files and now I’ve no idea what has happened!
NB if you want a copy of the Conduction ppp you’ll need to email me, as it has embedded video it is a whopping 484 MB! I’ve taken out the videos and its just 98MB
Thanks to Adam P for holding the camera as I did this demo. It shows so much Science in one large boiling tube! Convection, lack of conduction, state of matter, floating and sinking, density! Hope you like it.
The gauze is there only because the ice floats on the water and the ice needs to be at the bottom for the experiment to work.
Below are the resources for the HEAT topic that you’ll cover in S1 Physics. You might not be given all of the information by your teacher, but you can always use the additional materials to read around the subject, that’s what makes a successful learner, confident individual and responsible citizen.

A document on how to succeed in Science has highlighted the following skills and this is what you will be marked on during the HEAT block. Everyone starts with 3 points as an average and you can go down to 0 (not usual) and up to 5 points depending on your contribution. Some skills are so important they count twice in the score!
S2 Forces Unit Material, containing the Assessed Practical and details for plotting graphs in Excel.
Wow! This is an important Physics topic, your first topic in the S2 physics course. All the info you cover in class is given below. We will start at the beginning but can rush through the bits that you’ve covered in primary.
Forces powerpoint and powerpoint pdf file for 2021 onwards
In the back of your jotter write a piece “What I learned about myself in S1 Science” This is not the topics that you covered- I know those, but what did you learn about yourself, your ability to think for yourself, try tasks etc. What skills have you learned .

Revise the work you’ve completed this week and previous weeks
If you haven’t got results for the Hooke’s Law Assessment use the ones below. Copy the results into Excel, find the average extension using the formula =average(range) . Then plot a graph of Weight against average extension.

There is a separate post on EXCEL with details of how to create a table of results and plot a graph in Excel, which is useful for all students studying Physics, and other Sciences too- a useful life skill.
