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.

- uses- relate to properties
- atonic structure
- use Bitesize, wikipedia or other sources
- summarise your research neatly in your book
- everyone will be asked to feedback next Thursday
Work for week starting 25 Jan
Copy and learn the vocabulary above. This does not mean just reading it! Copy it into the front inside cover of your science book. Learn them by heart so that you know them without looking. Test yourself. Copy the list onto a sheet of paper as well and stick it up in the kitchen or somewhere you see it every day. Learn a new one every time you pass.
Learn and memorise the symbols for: Hydrogen, Helium, Carbon, Oxygen, Nitrogen, Lead, Gold, Sodium, Magnesium, Iron, Sulphur, Zinc, Calcium, Aluminium, Chlorine
Read and complete ALL of the States of Matter unit and the Atoms, Elements and the Periodic Table, Chemical Reactions and Tests units:
Draw three sets of small squares or circles to represent a SOLID, LIQUID & GAS. Draw these in a triangle with arrows going between each STATE of MATTER. Write the words for CHANGES in states of matter next to the arrows.
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.
- The Physical World is made up of Matter, Energy & Entropy
- MATTER: has Mass and takes up Space
