[Louise McFadden]

I'm really interested in my projects being medical-related but don't want to get over my head. Does anyone have any good ideas? I'm kind of thinking along the lines of exercise for biology but chem is proving tricky. Can't do aspirin tests cos someone else got it first!!
Thanks a million

:rolleyes:

Hi Lousie the vitamin c test is mentioned in the post ah chem projects if thats any help??

Can you not do aspirin but with a different aim?

Three boys in my chem class ( and there's only 7 of us! ), are all doing theirs on wine analysis, but investigating different things!

I did my project on indigestion tablets - but be warned it was quite boring and repetitive. I tested how quickly they raised pH, Co2 production etc. Was not too bad but probably wouldn't do it again.

as long as you get loadsa graphs with nice curves then that's what the markers like

[ehart]

My chem and biology teachers told us that they like references as well.

EMMAXX:D

[KL Chalmers]

Yeah, they definately like graphs, references, and diagrams. I added lots of them and it made it look a whole lot better than it really was. As long as you know a bit about it when you have to do your oral you'll be fine, even if you don't really know what it means!

If you are doing an exercise based project for biology i can help you out as i am just about to finish my final hons year degree in sport and exercise science before going on for medicine.

My dissertation investigates the way blood glucose concentration affects anaerobic exercise performance. This has never been investigated so you could do something similar and get away with saying what you want as there is no information to contrdict your findings
:D

that's cheating

[MartinC]

l'm doing wine analysis for my chemistry project, and was just wondering if there was anyone else doing that, and if so, what factors they investigated. Also, does anyone have any good medically related ideas for a biology project (other than the glucose tolerance ones, coz l'm not allowed to do that)

thanx

Vitamin C is supposed to be a good one. I haven't done CSYS biology personally but a friend did it and he said it was reasonably simple to do.

I'm doing physiology at the moment. I remember doing a project in first year which involved working out respiration rates with a spirometer, body mass index and % body fat. We then took a note of everything we ate and did for two days and worked out how our intake compared with the energy required. I haven't got all the notes but its a start. Your teacher could possibly help you when you work out your metabolsim output. It was a really good experiment.

thanx - l'll talk to her bout it

[jo.kane]

No problem. If you need anymore help give me a shout. I might still have the book with details so I'll have a dig and see if I can find it!

If you have the equipment at your school you could compare the respiratory quotient (RQ) of diabetics to non-diabetics. As it is suggested that diabetics utilise free fatty acids more readily as a fuel source compared to non-diabetics. This would show up in a simple expired gas analysis. I think that if the RQ value is below 0.7 the predominant fuel being metabolized is fat and around 0.82 or 0.9 the predominent fuel is glucose (i can't remember the exact value of the top of my head).

The RQ is just the percentage of oxygen to carbon-dioxide in the expired human breath (i think???). Just collect a sample in a bag and analyse the percentages of gases.

I'm doing Identification of an Unknown. Sounds interesting, huh?
Anyone got hints on TLC?
I also get to use an NMR spectrometer, which should be fun!!!

:moon: :moon: :moon:

[ehart]

TLC- as in thin layer chromatography?

I think one of my teachers said propanone is a good solvent

[elliottsimpson]

TLC as in tender loving care? Plenty people here with suggestions, I'd imagine.

[kenclark1uk]

whats a NMR sprectrometer???

:confused: :confused: :confused:

[andrewbaillie]

Nuclear Magnetic Resonance I believe.......no clue what its for though!!!!!!!!!!!!

[ehart]

i think its used to work out the main functional groups of a compound

[Hayley]

I have to use Thin Layer Chromatography to identify which Amino Acid out of a possible 5 is the unknown.

Then I need to use the NMR spectrometer at Bell College to verify the results. But I've had some problems trying to find decent solvents for all the amino acids!

[Damien]

You can't go wrong with Brut aftershave - that would dissolve anything!

[andrewbaillie]

Or old spice? No offence to anyone here that wears it.....!!!

[Hayley]

Gee thanks guys. My Chemistry teacher probably wears both, so I'll ask him about it.

:evil :lol :evil

[hugbug3000]

you're lucky your chemistry teacher WEARS aftershave...

last year mine, (name of Dr. Briggs.... never Mr. oh no, not if you wanted to remain alive) seemed to rejoyce in fumigating the class with his cigarette smell.......

mmmmmmmmm....... and they wonder why we fought over the seats at the back of the class....

[Hayley]

Hmmm... sounds like a pleasant guy.
I still don't know what I'm doing about solvents!!!
Oh well, maybe I will try the aftershave.

:lol

[elliottsimpson]

I have used aftershave to clean a white board after someone (no - not me) used the wrong type of pens on it.

Also used it to make a few corrections to overhead projector sheets when using solvent based pens - if you use water soluble pens you have to be careful to not get sweaty fingers or carry the OHP sheets in the rain - can make a right mess.
