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.

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.

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.

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.

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.

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!

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 · 16-06-2011 03:53PM

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.

FatRat · 16-06-2011 03:56PM

Slow show, I'm positive that they would accept radiation as an answer aswell as conduction. I did conduction but radiation would have been right too.
As long as you said that the white cup doesn't give off much heat through radiation, but it still gives off some. Because of this it would take ages for the water to get hot, but it would eventually. You'd probably get a lot of the marks for it. Obviously conduction is the more obvious one, but you have a point. Radiation would also heat the water in cup B. But only by a small bit.

Slow Show · 16-06-2011 04:03PM

I don't think I deserve any marks tbh, didn't read the question properly at all and made no reference to different colours.

it's my own fault, I should have known to read every question so carefully. I'm hoping it won't cost me that A I want so badly but meh.

Out of curiosity, what was going on with that magnesium question? Hopeful I got lucky and got it right.

I said that the compound was magnesium oxide. And the thing about the mass was that the magnesium reacted with the oxygen in the air thus forming an oxide layer and increasing it's mass.

That's right.

I guessed. I said the mass increased "because of the gas in it" hopefully I'll get 3/9 :cool:
As for the other two. Complete guesses. I said charcoal for what it created. :pac:

Slow Show · 16-06-2011 04:20PM

Yeah I was completely dumbfounded and said something about expanding on heating. I did say magnesium oxide though, so 3/9. :cool: Should have thought about it corroding, ah well. Waiting for the exam papers to come online so I can tot up marks and calm myself, looking back I suppose I didn't do too horribly.

scipsss · 16-06-2011 04:21PM

HARD

FatRat · 16-06-2011 04:29PM

I have the english version of my test here, because I did it through irish.

Looks like this is what I got: (I deducted a few marks for the waste management and plastics questions just because I might have lost a few marks in them)

Biology - 115
Chemistry - 106
Physics - 109
330/390 and with the irish bonus I'd get close to 350. :cool:

All I need is a good coursework B. It's funny, because, yesterday, I thought I was gonna go in and get about a C.
Not a lot about plants was good. Ionic bonding and atoms and all that stuff was crap, I was planning on guessing all of that if it came up and then I get 2 pages of it :rolleyes: All the stuff about the environment was nice since a lot of it is common sense.

I think I'll leave science at that! Happy enough with it overall.

cathalio11 · 16-06-2011 04:37PM

Guys, I said Magnesium DIoxide instead but gave the exact same reason and all, just got the name wrong. Will they slam me much for that?

Subsets of elements - Metals, Nonmetals
Blood - I said that it was high in co2 and low in oxygen entering the lungs, but had little co2 and was oxygenated when exiting
Hair thingy question - I kind of winged it on the question, but my teacher says im right so yay :L i said that the hair became positivly and negatively charged, causing them to repel eachother, and then at the end i just mentioned it was static electricity
Placenta - I said that it delivers oxygen in the blood to the baby along with nutrients from the mothers diet needed for development and that it cushions it
Copper and cups - yep, youre most definately right

Cells - I also said chromosomes

Plastics - I said something quite similar to you, so hopefully its right :L and i also mentioned that if plastics are burned they can release harmful emmisions
For the first question i said eggs and poultry

Home ec FTW ^^

P H A 7V T O M · 16-06-2011 04:50PM

The correct answers could have been Chromosomes, DNA or even "genes" though that last one is a bit simple....

For the one on the hot air baloon, the answer was "because the gas used within the baloon is less dense than air, so it rises" correct?

I said oils or butter on the first one. The only one I really think i got wrong

Well the same gas is used inside the baloon than outside it, i.e Air
I said that it rose because how air is less dense than cold air and so it rose ^^

Well I *think* my answer is still legit - the air, because it's heated, IS less dense, which supports the answer, hopefully that stillmeans full marks.

The gas the balloon uses to heat is propane, which acts upon compressed air very quickly, if anyone was interested... :S

Heat does rise in air, (technically heat causes the air to rise) as it does with any gas, so you are somewhat correct. There wasnt enough space to conduct analysis etc., you should get marks.

I was going to go into more detail about it saying how 'there's a fire underneath somewhere which causes heat particles go up to the balloon making the air inside the balloon less dense and making the air inside expand because it's heated', you get what I mean. :P But yeah, there was only 2 or something lines and I didn't want to write anything on the back of the extra work, lol.
