What is everyone doing as an investigation this year?

i'm doing 5 experiments to determine "g", how about the rest of you?

[Jonny-Sensei]

I'm investigating the factors affecting the flux density in a solenoid (which is basically a long coil of wire). I think I'm doing four experiments for it.

[Pringles]

Iam doing my investigation on the viscosity of water. I think Iam doing three experiments. Is there anyone else doing this investigation I need a few ideas

[BIG SIG]

I'm doing "An Investigation of Light Bulbs"

[Vixus]

I may do something with buoyancy. Or the venturi effect.

i've got notes on this from a class i'm doing at uni this year, incase you want any background info. just give me a shout

[Vixus]

Well, I've been forced into doing the coefficient of static friction, now... hope it goes well. I bet the investigation markers find this boring as anything.

[Dave]

quite a lot of people doing it this year. Science isnt dieing after all

i found out my mark from last year 7/25 achem not good.

i did an investigation on focal length. My problem was i couldnt get an experiment to work

I'm not quite sure what to do - I'm doing A levels though. Everyone in our class has to do a different one. All the obvious ones are taken - SHM and damping, Capacitors, Heat Capacity... bah. So confused.

I am supposed to be doing an investigation using a spectroscope to do something i think determine wavelengths, but im failing miserably, any ideas?

Sorry I'm blank on that one. I've decided I'm doing SHM damping using Eddy Currents which should be exciting.

Btw this is the HOLY GRAIL of physics investigations

I might do something with water turbines but I'm not sure how to go about this

[herbeey]

We're to start looking at the investigation on Friday... does anyone have any advice of the easiest or best investigations to do? I know that it shouldn't be just to do with these elements, but I'd like some guidance as to what kind of investigation is good and all that.

hey

im doing my investigation on factors affecting the force on a current bearing wire....i've done a few experiments, one of which refused to work and i've ran out of ideas

i've done the obvious ones like current, direction, length of wire, angle .....

anyone got any ideas??

[Vixus]

My static friction one is going well. I just hope its enough for a good pass.

[colinH]

i'am finding the wavelength of laser using different methods.

[Vixus]

Does anyone have any tips on how best to write up the investigation? Does it have to be long or will short simple paragraphs do?

[broughy]

if you ask your teacher nicely, they might let you have a look at some old investigations, just to see the style of it - ours did

I was doing inertia until 2 weeks ago, when suddenly my teacher changed it to stuff to do with hydrogen and a spectrometer.

The reason being that no one has ever done inertia as an investigation in my school before. She said there was plenty for me to write about, and the experiments were easy to get the right equipment/ cylinders... but she wouldb't help me out with any of it, since she didn't actually have a clue. She also told there was tonnes of background info, but gaves me no hints whatsoever. So I had to change if I was ever to get any help.

This new one is dead easy. I'm well on my way 2 weeks in.
