    I said that temp. changes cause radation takes place bu the heat from the hot water going into the cold ..?! i did not have a clue what to say?!!

    It was quite hard this year..hopefully praying to god i get an A!

    This. Radiation is when there is no medium. The copper was a medium.

    For the second question, stuff like wood and polystyrene were sufficient. Very good exam, no expiriments too. Hoping thats an A.

    Lol I wrote a Snake as invertabrate.... Why didnt I write Sponge? Oh well.

    Plastic or wood sounds about right, they're heat insulators, I was trying to think of that conduction experiment, y'know where the wax falls off the pins. I was right in saying that Iron was the worse conductor of heat in those, but it's probably a fair enough conductor of heat anyway, don't really know how I'll have done in that now. :/

    That is debatable. Some plastics can conduct heat, eg Polyacetylene...

    The only one I think I got wrong was "show sound is an energy", I wrote that electrical energy in speakers create sound, so that automatically proves it (since there was an energy conversion from Electrc to Sound), but thats correct anyway, isnt it? I know its not in the book though.

    That was radiation, I looked over it like five minutes before I went into the exam. :p Sure you might get a few marks for whatever you wrote.

    Darn ittsss, I thought it had to do something with conduction and convection- Thank God I didn't write any of those two words down though >.<
    I sure hope so <:

    Ummmm let's start a catfight here and I'm going to say that I think it was radiation. :p I can't be absolutely sure without seeing the question again, but like...heat was radiated from the cans, I remember that experiment really well.

    Yes, but the copper was an external medium, wasn't it? So, it WAS convection, not radiation, as there was some medium involved.

    And I said plastic for the final question.

    Same, I would have said said conduction and plastic.
    WELL GAIS, We'll know whos right when we get our tests back in September!

    Ps: Do any of you guys remember what color the cans were? Aren't they supposed to be black or radiation or something along those lines? >.<

    I said invertebrates were slugs...

    AnnKiins, it WAS conduction, but not convection. The medium (copper) was a SOLID, not a liquid or gas. If you wrote something on conduction, then you can expect a lot of the marks to be given.

    P.S Slugs are invertabrates, hopefully the examiner will forget that snakes have a spine? Probs not tho

    OK, majority rules I guess. I really have no right to argue since I can only say from what's in my book, not my extensive scientific knowledge...but in my book, well, for the experiment there's two metal cans which 'radiate heat' and as it says over it, 'all hot bodies radiate heat'. So y'know, that's all I thought about when I was writing but sure, I'm probably wrong. What did you guys say for the questions in it then, hopefully I'll have salvaged some marks.

    Is it conduction AND convection? >.<

    EDITED: Oh I seee, I wrote somethong on the lines of conduction so, fingers crossed ^-^

    What cans? Oh, the things the water are in? Well it's definitely conduction because the heat is passed from one to the other through the copper which acts as a conductor.

    Oh no, sorry, spelling typo.

    It was CONDUCTION, and conduction only, period..

    the metal conducted the heat from one beaker to the other

    who cares if it was conduction, convection or radation to get an A you need to get 330/390 so ya it will not matter if you lost 6 marks on that question :)

    Does anyone remember the questions on the can experiment...?

    Hmmm....
    Something along the lines of

    'Justify what will happen in a few minutes time'
    'Name a suitable [compound?] in which there will be no change in the two cans'

    @P H A 7V T O M-

    not if you did good in therest of the paper!!and even if you got 83 my teacher said they will put you up to an A as she corrects them! :):)

    What were the 2 colours for the Prism question?
    I guess Yellow and Blue

    Hmmmm....quite possibly got 0 marks for all of that so. I really wanted an A in Science too... :/ At least I think I did rather a good investigation...c'moooon September.

    Theres always attempt marks ^^
    You probably did grand in the other questions so chin up :D
    I'm not getting any marks for the investigation, I forgot to tick off all the boxes x__x
    Ikr? But I wanna get through Summer first!! >o<

    You might get attempt marks for naming a colour, esp. real rainbow colours, and not aqua-marine-teal-cyan-shmurple, which was, coincedentally, thevother answer you could have given to get full marks.

    'Twas a fairly tough paper but I'd say I nearly got full marks in Physics and had a good go at the other ones. Hopefully a B.
    All the mixture/compound/atom stuff always confuses me though.

    Physics was impossible this year! At least question 7 and 8, I really liked 9.

    Question 1: Our book tells us nothing about what the cornea does and I didn't study parts of seed either so tough question.
    Question 2: IIRC there were a couple I was unsure of.
    Question 3: This was respiration and reproduction right? Loved it, made up for my poor showing elsewhere.
    Question 4: Brilliant question, very happy.
    Question 5: Toughest chemistry question I felt IIRC but I'll have to jog my memory.
    Question 6: This was the atom question right? Whatever it was I did very well on it.
    Question 7: Found the one with the hair and sound impossible, and they were very likely 6 markers too. Messed up my good work elsewhere.
    Question 8: Wasn't a big fan of this but not catastrophic.
    Question 9: Dead easy, made the A far more likely.

    Looking like I got an A if I got 22/25 % on my experiment coursework yoke. Does anyone know how easily they give the 25%?

    Awful paper, *hope* but doubt I got the 77% :(

    I am very happy, none of the formulas came up and Physics (my absolute worst section) was pretty easy. Chemistry was a bit challenging but do-able. I thought Biology was fine, I'm just praying I get at least 25% from my project and experiments. I thought it was pretty good and so did my teacher so I'm not too worried. I'd reeeally love an A.
    After the exam I was talking to my teacher and I told her I was fairly happy, then my examiner came out of the room and told me I did really well. (He's a Science teacher and he looked through my paper..Is he allowed to do that?) Anyway, I'm happy.

    That paper went pretty well for me. Pretty happy with it. Had to make a guess here and there but pretty confident I'll get the A.
    What was the difference in the functions of the placenta and the umbilical cord and in the question about the earth and how its our primary source of energy? :confused:

    Two questions..
    Do we get our exam papers back when we get the results?
    I put red and purple for the colours that refracted from the prism thing in physics, will I still get full marks for that question? I read back a few pages it was violet, but I put purple. I don't know the colours of the rainbow so I just guessed purple.


    I actually really liked physics and chemistry this year. The only thing I didn't like about physics is none of the forumals I learned came up. I left out the cost ones and just my luck, they came up1 I'd say I got at least 60 marks on each though. I actually found biology pretty hard and that's usually my highest one. Hoping for a B.
