I'm trying to think of a science experiment I could do involving black holes. I'm not sure how to do one, and I'm pretty sure I can't build a hypothetical model of a black hole...
Another experiment I could do, would be with holograms. Again, I'm still not sure what experiment I could do.
Which one should I choose? The black hole? or the hologram? Or if you have any other suggestions, just post them! ;D

Hologram, anyday. I'll get my thinking cap on...

Iv always tried to do something like that but the lack of materials stop me (ie, ahologram machine/ a black hole). I suggest doing it on the computer. Use a program to do a hyperthetical black hole or hologram system. If you could, you could make a program for the black hole/hologram machine and imput data and study the effects. Thats what scientists do when its too dangerous to do it in real life but in your case it is accesing problems. Programs I suggest is a spreadsheet program and set up forulas for reactions a black hole/hologram has to different impurts. Experiemts you could do include finding a tipping point or a limit of some kind. You could use any program where you imput data realy, I'd use Game Maker and change the values of the 'sprites' (ie. objects). Also on Game Maker you can change the gravity and you have a visual represtentation of what you are doing. You'd have to get info and data on the black hole/hologram. I suggest a black hole as they are simpler. You could work out the effects on differnet masses and speeds etc. The reason I dont do it is I havent got anything to experiement. But if you need any help I will.

The reason I dont do it is I havent got anything to experiement. You can experiment on me. Shove me through a black hole and see where I end up. If I end up anywhere. Lazer, the experiment you're thinking of doing sounds quite difficult - but then, I was only C-average when it came to Science, so it may be quite easy for anyone who's very good at the subject. I agree with Adam that it would probably be easier to do it on a computer.

You can experiment on me Sounds wrong You can experiment on me. Shove me through Sounds wronger You can experiment on me. Shove me through a black hole and see where I end up. If I end up anywhere. Phew! Thats better. (Thats what I was thinking as I read the post. The first bit sort of caught me off guard.)

So like....if I was going to do the black hole thingy on the computer, how would i get the program right?

To be honest, it's far, far too complicated. Not sure why Adam suggested it. It'd be much easier to do something with a hologram, and they're fairly easy to find.

Use Microsoft Exel.Islander, where have you seen a hologram, and if you have, could you experiemnt with it? (In real life not digitly)

Adam, I think I've done a fair bit more modelling in my life than you - I know you can use Excel, besides, there are many better pieces of software out there for modelling. Anyway, that doesn't really count as experimentation - not sure if it would fit the brief for lazerxangel's project.
And where have I seen a hologram!?! Are we talking about the same thing? Holograms are everywhere! On credit cards, on money, on DVD cases (thousands of security applications, for example there's a hologram at the bottom of GCSE's to prevent fraud), on wrapping paper, on novelty bookmarks. As for more advanced holograms, well there are always a few in my local Vue cinema advertising various films that are currently out, there are many pieces of art etc. etc. etc.
...You get the picture.And yes, I'm sure there's some experiment you can do with them - diffraction gratings would be a good place to start. I'm not quite sure how you'd carry on, but I'm thinking on it.

Oops, yes I did get the wrong hologram. With the one your thinking about i have got a TARDIS version when I bought my Sonic Screwdriver.
Also other programs for modeling are either expensive or for to download and I was trying to make it easier for Lazer.
I think nmy project brief is easier to do and is any case the origianal brief was sketchy.

Honestly, if I were you I'd choose something a bit more straightforward and standard that black holes and holograms - something your school is guaranteed to have the equipment to do. Does it have to be physics related? If so, there's no way I can help (the only experiment I even vaguely remember from physics was something to do with springs and putting weight on them for some reason) apart from suggesting going to your library and checking out some practical textbooks for ideas. Mind you, that would be my advice if it was chemisry or biology. I don't see the point of reinventing the wheel for a school project. In university, sure, go for gold, but in school it's easier to pick something straightforward that's has easily controled variables and is easily measured or whatever and just being precise and throrough in technique and in your report. Just don't make the mistake I made doing psychology coursework - keep it simple and don't try to fit too many ideas and hypotheses into one project! (I will be furious at myself if me overcomplicating my coursework means I haven't done well ¬¬)

Yes I think picking something less obscure than black holes or holograms is a good idea. i like the chemistry and biology idea as they have some substance to them and a lot of physics is theoretical or is hard to test. With chemistry and biology you can test things easier. is this for school or just for a laff?
I suggest chemistry is better as with biology you can only test on plants really and that can get boring.
With chemistry I suggest not to just randomly mix chemical in hope of finding something interesting but monitoring a percific reaction such as dissolving but something more interesting than that.
You could always fix both subjects and so the effects on certain chemicals on plants. Either in the soil or as a pesticide or Miracle-Grow product. You could see the effects and differences between different chemicals on the plants and even if it is worth getting chemicals for your plant.
I would not eat anything you put chemicals on as a warning or keep plants sprayed with chemicals in the house.
You could always if you wanted just to keep to biology cross breed plants/flowers which would actually be cool. I suggest picking flowers/plants in the same 'family' as they are most likely to breed as some animals do not breed together.
You could also study the effects on living conditions of the plants but thats a bit boring.
Just remember in what ever experiment you are doing that be mindful of what chemical you have and where they are going and also remember to keep it a fair test and treat all things the same except the thing you are testing.I feel like a teacher LOL.
If its for school you should get a lot of support etc.
Gosh that was a big post LOL

If it has to be Physics, there are thousands of easy experiments that I could suggest, and to be honest Physics would be much easier than either Biology or Chemistry. Earlier this year I did my practical coursework for A-level Physics, so I have done quite a lot of planning and performing Physics experiments.

Wow...so many ideas! Maybe a black hole or hologram is too hard...but my teacher says I have to come up with an original idea that's middle school-high school level. So plants may be a bit hard to find an original idea from.

Right, now that I have some leaway, I'll be able to think better!
Give me a short while...
