Science OL & HL

All discussion and questions about the Science papers goes here, following the exam.

Please keep off-topic chat elsewhere.

Good luck all.

Finished early, such an easy exam, so happy.

How did you do?

Just finished Science exam! :P

I have to admit, the questions were tricky but i've managed. I know I got every question right except the one with the Iron and Sulfer table as my teacher said that shouldn't be there as it's not really on the course(I gussed red for the colour of ironsulfate and got it right! ). I had to do the last question without a calculator, such an easy question if you have a calculator. I used up half of the rough work page at the back just to find out what 500/1.5 is ... I think I got the answer right because the answer I got seemed logical and I think a few people in my class got it too.

Overall, a good paper, probably not the easiest in the last few years, but a do-able paper. I finished early too! Easy A .

Definitely an A without any doubts (as long as I get my 35% on the other work), one question I couldn't get was the Chemical formula for the Calcium Carbonate question. Raging about that, apart from that, everything was more than do-able. How about yourself?

2HCL + CaCo3 ----> H20 + Co2 + CaCl2

That's what I wrote.

My teacher was really bad, so I thought it was a dodgy enough exam. Should have 35% in the bag, so I should, hopefully, get a B.

Ninjah Tigah

Lol, I forgot all of them, apart from Calcium due to studying the reactive effects of Calcium, Magnesium, Zinc & Carbon in water. Thanks very much. The examiner will most likely look at my answer like O.o

A lot of questions were similar to 2007 paper too btw. ^^

Maybe next year will be similar to 2008? I'd be very interested if this "science" follows a hidden pattern with the structure of the questions :pac:.

Ninjah Tigah

I'd be useless now though, due to the syllabus being changed lol.

Just home, good paper I thought. Maybe if I do well in Corsework B I can get the A I really was aiming for. On the paper alone I don't think I got that.

Just home such an easy paper the only things that stumped me were the co2 experiment and the equation but I am still hoping for the a because my teacher said my project was excellent

When I did that reaction my iron sulphate wasn't red haha, it was more like grey/metallic :P

Not happy with how the exam was worded, ''what part of white light is refracted the most''

Too misleading.

Average enough test. I have an awful teacher and I wasn't prepared. However I did give a logical guess for everything so I think I am capable of getting an A!

glitzandbits

Had to completely make up the carbon dioxide experiment hope I get some marks...

Masterful Sponge

Some questions were worded badly i thought. A if I did as well as I think I did anyway, and I get a greyish colour when I did the iron sulfied experiment too

abcdefghijkl

Ehh... that was pretty awful. Biology wasn't too bad, as I studied it quite well. Made a bit of a failed attempt at Chemistry, and had a lot of guesses in there (did not have a clue about the CO2 experiment). Physics was pretty bad too, again with many guesses. I'm a bit disappointed, as I did study for Science quite thoroughly, but I had no recollection of the answers to a lot of the questions that came up. I would love to get a B (think I got a C in that exam, but the other stuff may bump me up to a . Anyway, won't dwell on it.

Ya I was so confused on that bit, I had revised light the night before and I never read anything about that. Does anyone know the answer?

claryfray

Well i am rubbish at Science but that went really well for me
I also worked really hard on my Coursework B , so hopefully because of coursework B, I'll get a B (I'll probably just get a C though :P)
If I don't get like 90% + on coursework B I am blaming my teacher because she told me mine was perfect (and she is a really bad nd scattered teacher so...:L)

claryfray

Usually kids at school who don't do any study can pass on stuff we did in class, but a lot of people walked out of Science today saying they know they failed because everyone talks/messed 24/7 in my class and whenever my teacher talks its to give out about something

So we literally did nothing in class :L

Tricky enough, especially the atmosphere question we didn't do much on that I think

After the exam my teacher said it turns yellowish ... I don't care anyway, I think I got an A eitherwise .

I guessed red because red is the colour that refracts the highest. Red is the first colour of the septum so it's probably the "part of white light" that refracts the most as it starts from top to bottom, I don't know. We didn't cover that in class ... I just made an educated guess.

I guessed red too.

SuperMattDude

i also said red

OMG Same. That's exactly why I guessed red. Science is my fav subject but like my mom said, learning stuff from the book is not enough for this subjec. You have to learn a lot yourself. Most questions were really confusing.

CathalRyano

I didn't understand the refraction question and just guessed green. Hadn't a clue.

I said Red too ha ha.

I looked it up and I am still confused. That's how badly phrased the question was :P

Junior cert1997

I said violet and looked it up but I'm still not sure

BBC GCSE notes say

"Using a prism, you can split up white light to form a spectrum. (A prism is a block of glass with a triangular cross-section.) The light waves are refracted as they enter and leave the prism. The shorter the wavelength of the light, the more it is refracted. As a result, red light is refracted the least and violet light is refracted the most, causing the coloured light to spread out to form a spectrum."

So...violet is the answer?
