Now is the time to start really thinking about how you are going to revise your topics for the upcoming exams. One good place to start is to make posters for each topic. Invest in a cheap roll of lining paper from a diy shop and then go through your notes and text books and make a start. Refine your notes down to fit a poster and then you will have a visual aid which you can put up in a bedroom or if your parents don't mind you can hang them all around the house. The process of working out what to put on the poster will help you revise each subject and then just having them on view will be a constant reminder, once in the exam room visualising the poster itself should aid your memory of the subject.

Some key terms and exam tips.
Compare - Are the things alike or are there important differences? Which do you think is best? Why?
Contrast- Look for differences.
Criticise- Use the evidence to support your opinion on the value or merit of ideas, facts or views of others
If you want to be a scientist and
take part in real science, citizen science is for you. If you don’t believe me go a look at
Zooniverse.com. You can log on and help with research, which
leads to publications.
One cool one is Whale FM (see link) it takes recordings of whale song and looks for patterns. It has only been going for a short time but has two publications in peer review journals (top scientific publications).
One of the greatest experiments going on now, is the Large Hadron Collider at CERN. If you've never heard CERN it's a huge research facility on the France-Switzerland border. If you don't think it has anything to do with you, it's where Tim Berners-Lee invented the codes that brought about the Internet. So what do they do there? Have a look at this link and find out.
Okay, I know I am supposed to be more enlightened, but there has to be some 'boys own' stuff in science. Check out some fast planes.
Look at the number of marks. There is a simple formula that states the number marks is equal to the
number of points you need to make in your answer.For a one pointer, just say one thing, don't write five sentences. For a six pointer, make sure you have made six points.
We've all seen the reaction between alkali metals and water. If you haven't followed the links to the video.
You should know that:
alkali metal + water alkali metal hydroxide + hydrogen
We know that reacts vigorously because of the metallic structure. Metallic bonding is a matrix of positive ions surrounded by sea of delocalised electrons. The less electro negative the metal, the less tightly the electrons are held in the structure, a more reactive metal. Here is some original research showing what happens at the interface between the metal and the water as soon as the two are brought together.
If we don't find a different way of meeting our energy needs, but probably a little bit stuffed. In my humble opinion the future is nuclear fusion. Follow these links to hear an in-depth discussion on the subject and to find out more from BBC Bitesize.
Magnetic - Energy in magnets and electromagnets
Electrical - Energy in moving or static electric charges
Kinetic - The energy in moving objects. Also called movement energy.
Heat - Also called thermal energy
Electromagnetic radiation - Light energy, radio waves, UV etc
Gravitational potential - Stored energy in objects raised above the ground
Chemical - Stored energy in fuel, foods and batteries (the energy in chemical bonds)
Sound - Energy released by vibrating objects (including the molecules year)
Elastic potential - Stored energy in stretched or squashed objects
Nuclear - Stored in the nuclei of atoms.
Energy can neither be created nor destroyed, it can only be changed in one form into another.
When changing energy from one form to another the change is never 100%, there was always waste energy normally in the form of heat.
Read the question! I know you "read the question" otherwise how can you answer it. But do you read it properly? Do you read every word? It's very easy to see the question in which the first sentence talks about let's say respiration, and think the question is about just that. Especially in higher level exams this is rarely the case. Read every word carefully.
