I remember as a kindergartner creating a stupid shoe box to catch Leprechauns. We painted white paper into yellow to look like gold. Then I added a bunch of paper strings to "trap" the leprechauns but I remember taking out the strings and telling people that once the leprechaun was inside I would kick the box. The leprechauns would be in shock so I'll take his pot of gold.

well the whole saturated solution sounds very easy and explaining the chemical reactions would be easy as well. I wouldn't recommend anything too elaborate because there will be more issues that you may not be aware of... Best of Lucks!

Now that is super saturated T_T

I don't have anything for you cool idea for a math fair would be show the principles of a slide rule. But as far as science fair. Physics > Chem >>Biology imo.


are you joking? just for showing off cool shit chemistry is much better than physics, but i agree with that they are both >> than biology

edit: i'm not saying that chemistry is better than physics either, i'm just saying when it comes to showing off random cool experiment shit, chemistry is better.

If you took Bio last year you could do a project on biofuels, like ethanol.

Specifically I used a bacterium called Clostridium acetobutylicum last year to create butanol fuels. The growth media are relatively easy to acquire (some kind of sugar solution + beef extract + yeast extract + deionized water) and analysis wise you pretty much just need a mass spectrometer/Gas chromatographer. The latter may be a bit tricky to get (as they are FUCKING EXPENSIVE) but you can usually go to some college and borrow theirs. At least that's what I did. Then you just analyze results and say oh so and so bacteria >>> yeast ethanol, butanol is a good fuel, or vice versa.

Material wise the bacteria is about 30$ and the other crap about 20$. I used Carolina Biological Supply Company (they have awesome service, etc.) but you probably have a Western version of it.

I did that and got to be finalist at my state science fair and got $150. Go figure.

If you decide to pursue this line of project I can help you out a little bit, but college will keep me busy so I may not be able to be there all the time... lol.

Its Biology, Chemistry, and OChem, which is fucking hardcore.

HCl + NaOH => NaCl + H2O

anyways I bought random metals from a home depot, put them in HCl, and hypothesized which ones would be gone first, in order ofc.


one of my favorite ones to do (you better check your fucking math twice on this one)
mix equimolar amounts of HCl and NaOH (or KOH, any hydroxide salt) in a beaker, then drink the solution. i've only done this once... fucking scary. you can check ph before you drink it, but then it kind of ruins the fun (maybe it would work better if you don't tell them what you're doing when you're testing the ph) oh yeah, and you should just use one of those strips to test ph, i can't remember the name of them.

edit: oh yeah, you'll be fine unless you get the ph off by like more than 5


Uh... drink it? I'm pretty sure even if it was neutral I wouldn't drink it due to impurities... and if you're a little off, it won't kill you, but it will probably taste terrible.

then don't get impure hydrochloric acid and sodium hydroxide...

and that's why i said it shouldn't be too bad if you're off by ~5, but beyond that you'll probably get heartburn.

science fairs are so useless in high school

anything you would do can be easily researched -__-

Two that I've done to great success.

Make a device to measure changes in earth's magnetic field:

http://www.all-science-fair-projects.com/science_fair_projects/7/62/e2201d694a1199ad282084665caa9698.html

or make your own parabolic dish.

To be perfectly honest I just dunno if the latter one is too easy to be considered for your project, but the magnetic field one is solid gold, I did very well with it. I didn't use that specific design though, so search around for something better

You could try something like monitoring people as they play different video games or some shit. Like have a bunch of people of different age groups, etc. play a bunch of different types of games or watch different movies, then monitor things like heart rate, respiratory rate, things like that.

Magnetism is always fun.

You could hypothesize that if you put a compass on the ground that the needle would be inaccurate by X% depending on the amount of metal under the ground.

eh i think bio projects are cool
one kid who went to the national level at my school did an experiment to see whether mushrooms could facilitate habitat repair or something along those lines

i don't recommend doing just a random demonstration. i would try to come up with a question and an experiment rather than blowing something up, as much fun as that is

It's not going to be metal under the ground though usually- Compasses are usually off by a little because the magnetic north doesn't exactly match up with polar north.

some cool ideas but this kid is in gr.10 chem, im in gr.12 chem and i dont know understand half the shit people are posting, something easy like Na in water, or better yet like imBLIND suggested, francium! =D

Get a huge chunk of sodium and throw it into a barrel of water.

Warning: It will cause a big explosion
