    do we have the same paper for chemistry?? mines called "Bolivian Bonanza"

    I have the same one the class read it and we were all like .... :O
    I'm sure one of the smarty's in the class said he was going to revise mainly on C4 for it, i'm not too sure :/

    The face cream ones just like, placebos & double blinds etc. Our teacher printed off a sheet & was like, oh, what creams would they of tested it against? apparantly, cheap & cheerful creams to olay isn't a valid answer :/

    Physics is more with the motion (P4) and waves (p6)

    I'm more worrid about the chem tbh, xxxx

    aww and i dont have any teacher to help either do you have like any possible questions and asnwers form school you can post cos i'm on gap year
    and do you know what section biology covers? b1,2,3,4,5,6?????
    THANK GOD I'M NOT DOING PHYSICS :P

    I haven't actually read the Chem one, I'm sorry Just very poorly organised. I'll send you the Biology face cream questions I have and if I make any for physics/chem I'll pass them on too. Good luck!

    Hahaha, you're lucky(:

    I'll have a look, they just gave us a sheet of questions he got from another schools website(; 'cos he's hard(; hahah, if you're doing core, its biology 1,2,3, additional is 1,2,3,4,5,6 & triple is 1,2,3,4,5,6,7& pre release :/ xxxx

    Thanks sooo much )
    erm i got this thing anti-wrinkle cream for ideas in context
    the chemistry ideas in context covers c4 and a bit of c5&6 apparently ;p
    i dont get which section i should do for the antwiwrinkle cream thing :/

    lol haha "hard" teacher :P

    Hahahah, thankss) the anti wrinkle creams more to do with the peer review and the blind/ double blind tests with placebo's etc. I think its B3, xxx

    Hmm well, I have mine for Additional 21st Century Science?
    Biology: Brain, mind and memory
    Physics: Forces and rockets
    Chemistry: Copper in mobiles etc.

    Anyone doing these ones? We can discuss
    Yeh, I'm new oh here! Hi! lol i'm resittin this and the core one and have some questions that my teacher gave me on revision day in the hols just recently!
    Reply back and let me knw and we can help each other out!

    Thank You
    P4 Questions:
    1) Write definitions for:
    -Kinetic Energy
    -Resultant force
    -Momentum
    -Friction
    -Velocity

    2) How does the Gravitational Potential Energy change as the rocket lifts off?

    3) How long does it take for the resistance to get to 0?

    4) What is the height of the rocket after.. a) 5s b) 15s c)25s?

    5)Explain how the thrust changes with time.

    6) It takes a lot of fuel to launch a space craft. Explain why very little fuel would be needed once the spacecraft has left the earths atmosphere.

    7) When a rocket is travelling in space, there is no air. How does this affect the drag?

    8) Calculate the GPE of the rocket 20 seconds after take off

    9) Work out the change in momentum at 5 seconds after lift off

    10) Draw arrows on the drawing of the rocket to show all the forces in action. (Think about sizes, direction etc)

    11) Sketch a speed/time graph for the rocket.

    B5

    1) Which parts of the body make up the Central nervous system?

    2) What is the Peripheral nervous system?

    3) What is the sensory memory store?

    4) Explain how rehearsal facilitates information transfer from short term memory to long term.

    5) Do long term memory and short term work together in the brain?

    6) Explain how a neurone is adapted to its function

    7) What is serotonin and why is it necessary for survival?

    8) What is the gap between neurones called and explain how neurones travel across it.

    9) What must be done to increase the reliability of Prof Yanker's conclusion?

    10) Explain two ways scientists can study and find out information about the brain.

    11) Explain why it is harder for older people to learn new things.

    12) What effect does Alzheimers have on memory?

    I hope these help guys! I havent been given any for chemistry yet, I'll get those after half-term. If you can answer all these, you'll get an A for sure.
