Science...

Strokesa

I no its not til thursday, but i was thinking that il start studying for it today, so does anybody no what would be the most important experiments to learn? I have the less stress more success book and ive been told to learn all the experiments in it but surely we arent expected to know ALL THEM!!!
So does anyone know?

Irishstabber

Id def learn the food tests...my teacher never shuts up about them :mad:

Fobia

I'm afraid you are, and most will agree that it's near impossible to know everything on the course. So as with some other exams it can come down to pot luck on the day. As for revision, the less stress more success book doesn't actually cover the entire course afaik, but it should be ok for Thursday's exam.

As for what you should revise one thing I'd do is pick out two out of the four choices for Section D (I think it's section D...the one with horticulture etc etc), I'm picking electronics and energy conversions.

We only did two of them... Material Science and Food. And I hate Food (there's a REASON I didn't do Home Ec damnit) so I did electronics as well. It's such a short section in comparison to the rest of them. o.o Barely nothing to learn.

As for experiments... I've heard the preparations for Carbon Dioxide and Oxygen are important. A lot of experiments are obvious once you know the theory behind them. (I mean, demonstrating the transpiration flow in a plant, yeah, stick it in food colouring, cut it in half, it's common sense.) I'd say the chemistry experiments might be the harder ones, all the chemical formulae and stuff you gotta know, you can't exactly make that up.

That said, you might as well know your Applied Science sections really well since you KNOW you're going to have to answer on them.

*MmmPie*

I think some of the most important experiments are the preparation of CO2/O2 and the titration/neutralisation reaction experiment with HCl and NaOH. Learn all the experiments for the Applied Sci section cos they're guaranteed to come up.

Thank you!

princess fluff

dese are the things we were told that will come up. .
physics. . .
ohms law def comin up
sound
law of the lever
pressure
density
chemistry. . .
simple/dry cell
prep for carbon dioxide
distallation
water treatment and ph scale
exothermic and endothermic reactions
biology. . .
ecology
eye
soil
respiration
heart
reproductive system
just learn dese and ul be sound!!!

Nothing will "definitely" come up.

Alqua

Do you think we'll most likely get a chemical equasion to write/balance? I do not understand them at all.

PurpleFistMixer

Probably if it comes up it'll be in the short questions...

Although for chemical equations, it'd be an idea to know Photosynthesis/Respiration.

... which are each other's mirror images, don't forget.

If you plan on answering the preparation of O2 and CO2, don't forget those formulae.

Alqua

It's things like that that make me want to do pass Science! For pass, isn't it just the word equasions that you need to know?

I hear Physics, Chemistry and Biology will, maybe other bits

philologos

lol science is a pure fail for me

Fobia

Latent heat is tipped to come up this year apparently, as it was a hot topic up until a few years ago...

Flashling

My friends teacher got them all to sing a song to remember how to prepare O2, not as catchy when it's written, but here goes....

To the tune of BnBn.

"MnO2 and h2O2 make oxygen and H2O."

Wow, it loses alot in the translation....

Strokesa

Rock on!

modular

What is the tune that it's sung to exactly?

I presume it's an all-girls school?

Do you do the "dododododos" in between the Mn02 and the "and" yeah?

You don't remember the BnBn ads modular? I presume it's the tune of that.

PurpleFistMixer

I'm presuming there are no "dododo" bits and you just say the "and h202" instead. If I had a mic I'd record myself saying it but damn I should be doing maths. And also have no mic.

modular

Oh, gotcha. Right, missed it in the post.

...and it was on The Muppet Show first, I believe.

Indeed, it was originally sung by Mahna Mahna and then brought back in later as the "phenomena" song, a big muppet fan I am

/me goes off to watch the clip again..

Strokesa

Ok, that actually works!
Seriously thanks i think il remember it now!

Flashling

Don't thank me, thank O2! Oh pfm, you're right, and I have a mic, but I don't know how to post music...al...ish...y clips. And I go to a mixed school actually!

I go to an all girls school and we never sing songs...or stuff...Id say its more likely to be a mixed school, personally. But maybe thats just cos my school is filled with a lot of the "OMG a song?Thats so ****ing gay.Why the **** are u so ****ing weird?" types...

I said it cus that's the kind of response that 90% of guys would give...cool school flashing.

My class is a little different, we'd happily try to sing it but just fail miserably

PurpleFistMixer

My class's response to a song would probably be something like "State ah dat!"

... ah yes, fun times.

Although we once sucessfully sang 'Frere Jacques', in canon. That was a unique occurance.

To be honest i couldnt giv a toss bout science........ im not gonna study 4 it cos im droppin it next year...........

Mysteryfish

there's just so much to study for science. I'd say go over some exam papers and if there's anything that you REALLY don't know or understand (i.e. you can't even bluff your way through), go over it.

JBoyle4eva

Well, if your doing ord level then don't get stressed: It's Mostly mix n match, fill the gaps etc. altough they will have ask for the most memorable experiments compelteted over the last 3 years, so don't get too stressed.

Higher level is all about what you kn'ow. You should now be revising all the chemical names etc.

Did anone else beside me have to learn Applied science by themselves? Our teacher never helped the applied science students but instead helped the local studies whenever he could!

lol ye theres just far too much to learn its impossible
