We spoke this morning didn’t we? That is a lot of things to cover in one test! It sounds like a difficult one. It is a bit hard to give you advice based on what you have said. Forces could mean a lot of things. As a mechanical engineer I use forces everyday. I’d say if you learn the basics of Newton’s Laws you’d be doing well.
Newton’s first law effectively says that an object will stay at rest, or continue to move at the same velocity unless an external force acts on it. The second law says the the Force acting on an object is equal to the acceleration of the object multiplied by the mass of the object F=ma. The third law says that every force has an equal and opposite force acting in the opposite direction.
As for food glorious food I have no idea what that is going to cover sorry! It is just making me think of chocolate. Hmmm chocolate 🙂
All I can suggest is to do some careful revision before the test but don’t worry too much about it because that won’t help. Read your textbooks and notes from class a few times and write down some revision notes that you can glance at before the test to jog your memory.
That does seem like quite a random collection of things to have a test on! I’m trying to think of where they might all be used together…
I think Naomi has got forces covered so I’ll see what I can add for separations. I’m a chemical engineer so I make use of separations fairly often. I believe the key is to think about the physical properties of whatever you are trying to separate. For example, if there is a difference in boiling point, density, size or even colour then there’s a way to separate whatever you have. Also think about what phase (solid, liquid, etc.) you are trying to separate and if you get two different phases then there’s another way to separate.
It might not be terribly specific, but my biggest tip on food is to make sure you eat well before your test. If you’re like me just thinking about food when I’m hungry will make my tummy rumble and lose concentration!
Good luck on Thursday!
I think the Naomi and Billy have given you some great advice! The thing that got me through my exams was practice papers just doing as many as you can so you recognise them when you are in the exam and know what kind of answer they are looking for! Also read the question at least 2 times as I always missed something the first time. And finally as soon as you start the exam write down all the formulas you have learnt because mid way through the test when your brain has been working on lots of different things its harder to remember them 😀
