Make Revision cards on anything that you think you will need to know. Keep using them, test each-other and order your cards with the ones you remember every time at the bottom of the stack.
Use the resources here, find your own (from reliable sources), make and use your cards for a minimum of 2 hour’s work weekly to keep on track. If you find anything confusing then spend more time on that area. Put in the time and the fog will clear and you will feel good about it.
Some videos may cover things that we haven’t done yet- don’t worry if you find some parts confusing, just focus on the parts that are familiar from our lessons so you can understand them. Watch more than once and TAKE NOTES- Just watching them will not give you much benefit.
Keep up with current issues in science! I will add any interesting links here, please pass on any that you find as well. Good sci-fi films and books can be excellent at thinking imaginatively about science, and bad ones are good so you can spot the things that they get wrong (like hearing explosions in space).
Keep trying the Cognito practice questions every week, watch the videos and make notes & cards when you find areas that you need more work on. Also use Bitesize, the KS3 Revision books, wikipedia and other legitimate resources.
Home Learning for 6 December
You can add to or amend the last (longer) answers from the last lesson, which we will go through on Monday:

- A meteorite burns up as it enters the earth’s atmosphere. Describe the forces involved.
- Why does the moon orbit the earth? [Don’t just say ‘gravity’]
Electricity generation. Look at p102/section 13 of your revision guide, and research in the usual places. We will discuss your answers and research together on Monday. You will need to use some previous work on energy processes, and a little bit of electromagnetism- this is difficult so don’t worry of you find it hard, everyone does.
- Coal fired power stations and nuclear power stations generate electricity in exactly the same way. Explain. [paragrah]
- What is the problem with fosil fuels? Why is the whole world saying that we need to phase them out? [paragrah]

Home Learning for 29 November
Waves waves waves. Remember- waves are fun. Lots of things come in waves, including waves, and waves of waves. EM waves are a bit more confusing, because there is no medium that is waving (like air or water), they are just waving at themselves really. Best to try to understand the basic properties of all waves and then think a lot about waves. Waves.
Try to find out more about the difference between LATITUDINAL and LONGITUDINAL waves, look at images and videos for both, draw your own representations. Longitudinal waves go aLONG, like you saw in the slinky. Find and learn the definitions for the new vocab in the glossary above. Look at waves, think about waves, make cards about waves. Waves.
Bitseize pages on waves are pretty decent: https://www.bbc.co.uk/bitesize/guides/zgr8d2p/revision/1
Also look in the usual places then test yourself with Cognito. When you know all about wave properties, come back to EM waves.
Home Learning for 24 November
Research the Electromagnetic Spectrum (this is a new image, with lower freq on the left now)
What is the difference between ‘wavelength’ and ‘frequency’? How are these two concepts related?
How are EM waves different to sound waves?
Describe all of the EM waves that you might find in your home. What are they used for and how are they different.
What are EM waves? What is waving?
How fast do they travel?
Do they get weaker the further they travel, like sound waves? Explain your answer.
Make a revision card for each of the sections of the EM spectrum, with characteristics, dangers, uses, frequency bands.
Home Learning for November
REVISE EVERYTHING SO FAR! Scroll down this page to remind youself and find links.
Create your own student acount with Cogito:
For exam board choose ‘don’t know’ and choose the combined science option. Choose Physics Practice, Topics 1, 2, 4 & 5. Choose the foundation tier (unless you find it too easy). Try setting yourself 5 questions to try each day, and try to answer them BEFORE watching the video for each (there is a play icon that will take you straight to the related video). There will be questions that we haven’t covered yet but any that are on subjects we have covered that you can’t answer, you must go back to the lessons and revise.
This is a fantastic resource that will help you learn and practice. The videos and other supporting material that we have used will help you when you get stuck or can’t answer the questions. Good luck!

Home Learning for half term
VOCABULARY: Learn the definition and usage of all of the terms listed in the gloassary above. Make a card for each if it helps you learn it- we will be using these terms from now on with an assumption that you know what they mean. Some of them (like voltage) are hard to understand, don’t worry- everyone finds them hard.
MAKE & USE your cards. You have a nice stack now, use them in the ways we have discussed, ask friends and family to test you, turn it into a game, improve them, add to them. They will fix this difficult stuff into your brains forever.
REVISE everything that we have covered so far this half term.
I won’t usually list videos any more, you know where to look: Cognito, Bitesize, search ‘ks3 physics forces’ on youtube. A lot of cognito videos don’t come up on their home page, but you can find the full Physics playlist here: https://www.youtube.com/playlist?list=PLidqqIGKox7UVC-8WC9djoeBzwxPeXph7
Download this pdf and work through the questions, using the formulas we have covered. Whenever you get stuck, research in the usual places until you know how to do it.
We will be starting on atoms after half term so it would be a good idea to do some preparatory work on those lovely little things.

Home Learning for the summer : Revision cards
Cards are the best way to learn lots of information. They can have simple diagrams or bullet-points, but shouldn’t just be full of writing. You need to make a minimum of 30 over the summer but 100 would be far better. Make them clear, neat and simple but don’t spend too long on each one. You could make 3 each day, or set yourself a weekly target.
Send me a picture of one of your best cards so I can put them up here and we can get ideas from each other’s systems.
- Use colours and symbols- neauroscience tells us that this helps the brain to learn and remember information better than just text on it’s own.
- Decide on a system to categorise your cards. A coloured strip down the side to show Physics, Chemistry & Biology works well. You could use symbols or more colours for different topics, for example you will need several cards that are about cells.
- You will use these cards for the next 3 years so you will definitely need a container (maybe a plastic tub) to keep them in.
- Highlight or underline KEY POINTS & VOCABULARY using colours and CAPITAL LETTERS.
- Think carefully about how much information to put on each card. Don’t cram it in, it needs to be quick and clear so you can pick up a card and read it in about 10 seconds.
- Make cards for things that you don’t know, using your science book or text book.
- Some cards could be test cards with questions on one side and answers on the back. You can test yourself and then each other in September.
- We will continue making cards next year so eventually you will have a lot of them, so make sure you are happy with your system and make sure they are neat and clear.
Using your Revision cards
Take them with you if you go away, keep them handy so you can glance at a card several times each day. Just making beautiful cards and keeping them in your room is a waste of time.
Everyone must find their own best way to learn- we are all different but here is what I find useful for me: Pick up a card several times every day and read the information. Put the card down and see if you can remember everything that was on it. Next time try to remeber before you look at the card. Keep going until you are sure you know that card fully and can remember it even after a few days.
Good sleep is essential for information to be stored in long-term memory. Exercise and good diet have also been shown to help.

This may seem a lot of work but we need to start getting ready for GCSE level work; you should expect to be spending over 4 hours each week in the 2 years before your GCSE exams, so at least 2 hours each week would be the minimum for now so you are well prepared for this. Feel free to find out about other areas of science but remember that chemistry is what we will focus on now until March.
Intro to Chemistry
Watch this video:
Yes, it’s an American accent, get used to that. Please watch it twice, take notes of any key points and also anything that you don’t understand. There are many similar videos, some good, some not. Try to find some other good ones and write down or save the link for everyone else.
Periodic Table- download
Please download this onto a pad or computer, you will need it. A printed version is nice too.
The app/online version is good as you can see what each element is and what they are used for, but a printed version will also be useful for lessons.
We will soon be playing Elemental Bingo each week using flash cards and memorising the key info and symbols.
For further listening/learning I can recommend this (optional) audio series on the BBC which gives plenty of info on the uses of some of the elements:
Make sure you learn all of the key words in the glossary at the bottom of the page.
You will need to complete ALL of the units in Bitesize Chemistry in a few weeks so we can start of the GCSE level stuff. Feel free to move on to the next units, but it’s best to learn each one really well.
Work for week starting 11 Jan
BBC bitesize Chemistry. Read & watch all pages on both of these units, then take the tests and see what you can remember. We will have a little test on Thursday. It can seem like a lot to remember- you definitely won’t get it all the first time. Repetition is the only way. These webpages contain EVERYTHING that you need to know for now, so use them.
