What did people say for that colour yoke on the dispersion? I said 'red' and 'violet'. Please have saved me, Richard of York...

Also, y'know the first question on the rays, what was the answer to that? And was the next answer 'refraction?'

Red and Violet are correct, refraction is correct, and the first answer was reflection.

I'm pretty sure it was reflection for the first one. It couldn't be anything else could it?

spirit_77

this was the subject i was most dreading as it was the only one i failed in the mocks,but was delighted with it.in my opinion the easiest paper out the last 5 exam papers.Hoping to get a B

Wow I should have remmebered that, I wrote red and purple, I'm such a dope xDD

I said refraction, didn't get the other part though!

YES. :L Lads, I think I got full marks in Physics, that was the question I thought I did crappy enough in, (despite it not being very hard )..if anyone wants to tell me if Iron was a suitable answer for the last question on a metal that would do...something, can't remember which, then that would make my day.

That went awful

oo was the last question not on a material you could replace the copper with that would not allow the change to occur? I.e an insulator? I said plastic or wood

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

Was it not conduction..? The transfer of heat through a solid without the particles moving? Therefore both cups will become warm.

It was conduction, Slow Show, not radiation.

And I said plastic for the final question.

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.

Slow Show wrote: »

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.

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. 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.

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? >.<

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..

Oh...so it seems I read the question wrong. Well, FML anyway. I'm such a dope...

Don't beat yourself over it c:
Everyone makes mistakes ^-^
I probably got half the paper wrong xD

healy77

the metal conducted the heat from one beaker to the other

fabulousdiva

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

healy77

it could be the difference between an A and a B

AnnKiins

Slow Show wrote: »

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'

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
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<

Damn
Sill a fairly alright paper, Id say I got a B

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%?

shadowninty

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

Cakeplease

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.

phenomenale

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?

Joe95

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.

No, you do not, as far as I know, you cant see your JC papers ever again. You can appeal the result, but not view them (You can freely view the papers in the LC).

It depends if you get a mean examiner and or the marking scheme.

Physics seemed to me like by far the hardest section. Totting up the marks at the end it was just about my worst section even though in the mocks I got around 90% of the physics marks.

The results are just a letter so something like A or B. What's all this obsession with how good physics was I thought it was tough.

So we don't actually get the exam sent back to us? That sucks.
I don't know, maybe because I put around 3 hours of studying physics last night it made it easier for me, I've always liked physics though.

i think i did decent.
was a weird paper, idk.. hopefully a b!

FatRat

Few questions:

What are the two sub-sets of an element?

What was the thing about after the blood passes through the cappiliraies in the lungs what happens to it. I said, it mixes with O2, mixes with water and mixes with more red blood cells. Is this right? I think mixing with O2 is right, but what about water and red blood cells?

For the one with the hair rising on your man. I wrote "Because of static electricity" I didn't write anything about electrons. Would this be enough for the question?

For the question on the placenta, what does it do? I said the embryo grows on it and it acts like a cushion for the baby. Is that right?

For the magnet one about finding out which sid of it is the north side, I said put one side next the a compass and the compass should point to what side that is. Probably wrong, but is it?

And for the cup one, I got it right alright, but I said that A will cool down and B will get hot. B will get hot because the copper will get hot and then it will heat up B. But I said, since a is hot already, it will eventually cool down because it's exposed to the air. Is that right?

And..... for the animal cell, when it asked name an important structure in the nucleus, I said chromosomes, is that right?

The bio-degradable bottles one threw me off. I said it would upset habitats and if animals ate them, they could get sick and die :pac: Any chance of that being right?

Anyone who answers all these question, I'll give ye a million a euro.
I thought the very first question was the hardest, it the only one i couldn't even make a guess with .... threw down tuna in the end cuz I'm a mad bastard. :pac:

For the cup I basically said that they blanced eachother out and heated the copper to an extent that it was able to heat up the cold one but had a cooling effect on the warm one.

I guessed reactive and unreactive elements for my two subsets.

Blood leaving the lungs contains more oxygen and less carbon dioxide than blood entering the lungs.

I'm pretty sure genes are the important structures in the nucleus, open to correction though.

I think the chromosomes are the structures and genes are in chromosomes. Also my book, in the only place that it vaguely categorizes elements has metals and non-metals. Got the lungs one, happy I studied the whole gaseous exchange thing and it came up.

Also, I think what a test for water was came up twice and I left out what colour the paper should turn, will I lose marks? I also accidentaly said water vapour instead of water for photosynthesis, will I lose marks?

FatRat

Bita research there and genes and chromosomes should both be right. Chromosomes are in the nucleus but genes are also in the nucleus and are "important" so there's no reason it should be wrong.

I'm on course for an A. It seems I got most stuff right, even though I thought I got it wrong during the test. Pessimistic result would be 300/390. Optimistic is 340/390.
Basically, if I do really well in coursework B, I should get an A. And to answer a question someone asked above, coursework B is marked VERY easily. As long as you did it right. You can see the marking scheme on examintions.ie. Just go into the marking scheme for the 2010 science test, scroll down and it's at the bottom of the page.
