Yes yes I know. This has been posted too many times, but after doing a search of the forums I still haven't found a satisfactory experiment for a science fair.

I am a 10th grade student. I'm mostly interested in chemistry and physics experiments, as well as engineering. Financial-wise, I can spend about $500. The project has to be an experiment, and I'd like to do a particularly difficult one, if possible (but not TOO dangerous). Any ideas? Thanx a lot!

How old is 10th grade? What topics have you covered?

 

In terms of sterling, £285.070 is gonna buy you a lot of LASER.

10th grade = 15 - 16 years old. Topics I don't mind, as long as they are within my categories, are manageable, and are not too deadly. If I feel that a topic is too advanced I'll try my best to understand it by researching.

That sort of freedom is awsome. Does the school give you the funds?

We're doing "practicals" for A-level (17-18 y/o) that is one fixed project

 

Does a Science Fair mean it'll be a competition (like on the Simpsons)?

I feel sorry for non-americans, who have little experiance with science competitions. It's quite big business in the US... the first prize for the Intel Science Talent search is $100,000. There are other competitions with similar prizes.

 

Not only that, these competitions have stimulated me, as well as many others, to enter the field of science research.

yes yes. So, any ideas for the project/experiment??

Thanks a lot.

Your best bet is to read some papers on subjects that you're interested in and do some sort of follow-up or related experiment.

first option...

1.thermite

2.Co2 laser

3.nitrogen laser

4.turbocharger jet engine

Could you explain each of your ideas for me please? Thanks.
