Title: CIE physics as practicals
Post by: Sanjee_KP on October 20, 2009, 12:21:59 pm
Does anyone know what we'll get for da as practicals. I'm in need of serous help here. My practical skills are very poor so I really need help on this. Or do you know how to get the confidential instructions? Please help me!!!!!!!!!

I'm doing physics on 3rd nov.

Anyone with ideas of what can come?

dude anything can come
some ppl in ma area are actually doin different variants of the same paper....
i jus dont want electricity..i hate settin that stuff up!! :(

Well . No . there are two papers 31 and 32 being on 3rd n0v and 27th oct. Praticals arnt hard . jst do stuff wif errors . The linear equation thingy wid graphs ( y=mx+c ) and how to make tables ! =D

But if we cud see da confidential instructions we will know wat r da practicals we r going 2 get, so any idea how 2 get dem....

NO CHEATING........FIRST OFFICIAL WARNING.

And how come no 1 else saw this thread??

I am going to disagree. This is NOT cheating.

Schools are supposed to hint what kind of experiments can come in practicals. It's their job. Our school, however, is new to the system and thus don't understand what to tell and what not to. So, they tell us nothing. Meanwhile, in other countries (and I am sure about this), students get the help/hints they need and have already done many related experiments via guessing, etc. We suffer as the threshold is always up there, you know (I did brilliant in my paper 1 and 2, but failed to achieve decent marks in paper 3). In addition, practicals are all about practice, so we need all the practice we need. If we know what apparatuses will be used or just a hint, we can try doing all possible experiments, etc. It's not like we have the question paper or anything. It's like pre-exam preparation, which is essential as we don't really know what to do before a practical.  At least, I don't. lol.

Anyway, if you feel otherwise, please elaborate.

Thanks.

No hints or whatsoever.....Not allowed on this site. if you think your school will tell you, you may well approach them. And if they tell you, i don't see that happening in a good school, but if they do, then that is in itself cheating

You may discuss the possible practicals but not let out a single thing which was on the paper. I hope you understand. These r the rules of our forum. Our member are supposed to abide by it

Thanks

Obviously no one knows what REALLY will come in the exam, not even the school. 99% of schools do hint what apparatuses can come, then us students gather and try to guess what CAN come.

How is that cheating?! >:|

hey...even im giving my phy pracs on 3rd....
im really worried bout setting up d electrical stuff...

if someone cud post nething helpful it'd be gr8....

and tbh i do think tht getting evn d apparatus list in advance is cheating.....
though now i'm wishing my school cud cheat this once... :(
Title: Re: CIE physics as practicals
Post by: Lana Wolf on October 25, 2009, 06:50:26 am
the whole idea of an exam is not knowing what questions are going to come...

and By the way my school duznt hint anything at all....

You may guess....guess as much as you want. No one is stopping you.
Don't let things out. The forum had defined cheating. It is for the mods and admins to decide what is cheating and what is not. We will take action appropriately

Thank you

For a guess, you need some sort of starting material or an idea. .

Never mind. I guess you know better.

it is considered cheating, actually.
if anyone finds out that your teachers have been giving you "hints" and reports you/them, you may well be disqualified.
at least, that's what my teacher told me.

but yeah, i'm resitting AS physics and i'm doing the practical on the 3rd as well. dunno what to revise tbh, might just go over electricity experiments.. i get confused when setting up that ammeter/voltmeter thing  :-\
Title: Re: CIE physics as practicals
Post by: nid404 on October 25, 2009, 09:37:04 am
jst remember......ammeter in series, voltmeter in parallel....that is all u need to know for setting up
Title: Re: CIE physics as practicals
Post by: falafail on October 25, 2009, 09:52:45 am
oh, no, i know how to set them up.. but there's this thing that works as both a voltmeter and an ammeter, and you have to turn this thing.. hold on, i'll find a picture. i don't know how to explain it .__.

Post by: nid404 on October 25, 2009, 09:55:23 am
It's a digital multimeter....you just turn the knob to tell the machine what you want to measure :)
Title: Re: CIE physics as practicals
Post by: falafail on October 25, 2009, 09:58:53 am
yeah, the whole turning the knob thing is what confuses me XD

k, so.. it says that you should usually use the 20V one for measuring the voltage, but what about the current? do we choose 20A?

how do we measure percentage uncertainity and percentage error ? and also... when we draw the graph is it necessary to start from origin ? i mean what if we have really large values for the y axis .. ?

thank you nid. and please tell me about the graph as well... is it necessary to draw an origin ... where both values are zero?

it's not a compulsion...it actually depends on the values

HEY nid! so if someone were to tell us what happened on a different paper to ours, would that be cheating? for example if some1 did the paper on 27th october, and that person tells us what they did in that paper,even if we r doing a different paper on november 3rd, would that be cheating? thank you.
Title: Re: CIE physics as practicals
Post by: MaNi_DaDuDe on October 31, 2009, 02:01:47 pm
I don't believe how that would be cheating.

Exams are on different dates.

However, Nid knows better; so wait for her response. :D

well guys....guys let get all this crap over....back to the discussion about paper 33....i heard that both questions are mechanic....no electrical questions....
and what i feel is that besides predicting on the paper i guess we should focus on knowing how to tabulate the data(eg raw data based on dp while processed data based on sf.....this is very important), calculating uncertainty in measurements, justifying...and most important thing is that knowing sources of error and methods of improvement..... guess i have to revise the  past papers
