Hi all,

I need to decide what the subject of my AH Physics Investigation will be.

What have other forum members done in the past or could you give me any ideas for what I should do!!

The more dangerous and original the better...

I too am looking for a good source on potential practical projects in AH physics.

Any help would be greatly appreciated

Hey, I'm doing AH physics as well, but we do not start our investigation for a while yet.

Do you read magazines like New Scientist? There is a lot of information in such publications which could help you with your project.

Most of my class subscribes to New Scientist or Scientific American.

Me 2 im doing advanced, weve also got a while yet for our investigations, but why not start to plan early.
Btw which investigation are you all doing in class?
We have just done the Outcome 3 one, the angular accelerationn with torque one.

[Holmes]

We've more or less been told ot keep it simple, the best opton being just to do something from the unit we're working on at the moment. Its a bit of a burden for us to start them so early but our teacher says he just wants us to get them done as quick as possible and out the way.

I need to put my initial ideas in by Thursday. At the moment it looks like being measurements of g, or something to do with centripetal acceleration.

We've more or less been told ot keep it simple, ...our teacher says he just wants us to get them done as quick as possible and out the way.

Our teacher who is a marker for the investigations at advanced higher was talking to use about that sort of thing. Apparently there has been an increasing downward trend in the quality of the investigations over the years that advanced higher has been running. From what she has seen the simple investigations tend to score poorly where as other invetigations which transcend the course tend to score well. Those investigations which seem to have been done "to get them out of the way" also seem to score poorly.

Now dont start ranting at me for saying that becuase I am sure that your teacher and you know what you are doing, I am just giving you the perspecive of a marker.

my investigation is to measure the focal length of a concave and cenvex lens using three different methods. i think its pretty good and has been done before and scored highly as far as i know

i know a marker and they say keep it simple and produce a good report at AH level,,dont make it complex

[Holmes]

Well i have to put in my inital ideas for tomorow about the project. after much research this afternoon ive came to the conclusion of doing something to do with refraction. Im going to find the refractive indexes for a liquid using a few methods. either that or i will determine the variation between the temperature of a liquid and its refractive index.

My biggest problem at the moment is finding 1 method let alone a few for measuring the refractive index of liquids.

Anybody got any idea about this?!

Took me ages to think of somethin aswell. How about measuring refractive indices of substances at different temperatures and pressures an seeing if there are any relationships. I knew a guy got killed trying such experiments, V dangerous, was of boredom mind, but might be worth a try

Thats what im doing, the refractive index related to temperature.

hey...my teacher just mentioned the projects to us today...said something about me doing one where you pour water through tubes and measure the speed or something like that....he told another guy in my class about the spectroscopy of a hydrogen atom...and another guy is doing torques....he said the easiest one to do is all the different measurements of g....and another possibility is how the resistance of an LDR varies with light intensity....sorry if thats a bit vague

[$impl¥_®i¢h]

Ive been given my investigation topic, and i will be investigating ways to measure "g"!! (woohoo)

[Dave]

they tell me thats one of the easier ones so congrats

[$impl¥_®i¢h]

Hey Dave cheers.
Im not sure if its easy or whether its hard. I dont think it will be extremly difficult nor will it be too easy.
I think its finding the value for "g", using things like Simple Harmonic motion, with springs, and also pendulums.

[Dave]

logical i don't know how the guy in my class is going to do it i am pretty sure he aint even thought about it

[$impl¥_®i¢h]

I havnt thought much about either, i was jut given it yesterday, so ill need to look on the web to see if i can find any experiments.

[Dave]

A-level physics textbooks are always a good bet for this sorta thing sad but true

[$impl¥_®i¢h]

Cheers, will try and get hold of 1, if ne 1 else knows any more good sources, then fire away!
