I suggest that you create a supersaturated solution first. Reason being that the more highly saturated the solution, the better the formation of the crystal and the larger the end product. This can easily be done by heating your solvent to a very high temperature and stiring in copious amounts of whatever is going to make up your crystal. Lower the heat as it goes and you should idealy end up with a very viscous solution, not so much of a liquid but more to the kind of stuff you get when you mix a bit of cornstarch with water. Thereafter dump everything in a beaker or bowl and suspend a thin wax thread in the solution itself. Cover up the bowl and leave to set for a few days. If you have done it correctly you should see a very nice, large crystal forming. Just a note though, don't let the thread touch the bottom of the bowl or even any thing other than the solution, or your crystal will be lopsided

One of my favorites is making carbon dioxide. I have used this with my nephews and nieces.\n\nYou will need water glass 6 to 8 oz\nbaking soda\nvinegar\nmatches\n\nput a couple teaspoons of baking soda into the glass (you don't need an accurate measurement)\npour in vinegar until the glass is about 1/2 full\nuse the time it fizzes to explain about carbon dioxide (do a little research for this part)\nlight a match and insert the lighted end into the glass (it will go out) or\nlight a match and very carefully tip the glass, pouring the gas over the match, it will go out. Be careful not to spill out the liquid. You won't hurt anything if you do, it just spoils the effect.

DO NOT add sodium bicarbonate! The pH is already too high. Bicarb will only COMPOUND the problem, not fix it. What you need is acid. Bicarb has an alkaline pH.

You could do a base and acid mix and explain the reaction, such as vinegar and baking soda.\n\nAlso the erupting marshmallow mixture is pretty cool... and edible.\n\nCheck out this link for a bunch of cool activities you could do.\nhttp://www.calstatela.edu/dept/chem/chem2/LACTE/K12.html

How about making your own sherbert using citric acid (available in chemists) and icing sugar? \n\nOr you can use those mini marshmallows and cocktail sticks/skewers to construct  something that can bear a load (a paper cup of water or a egg work well but make sure you put newspaper down first!)\n\nHow about dropping sultanas in a glass of lemonade? They'll sink at first, then rise, then sink again etc - can they explain why?\n\nOr use jelly beans and have a blind taste testing and see if they can catch their friends out.\n\nOr just a blind taste test with different things to show how we can tell sweet, salty, sour etc. Just make sure you know about any allergies/religious requirements first.\n\nAny help? These experiments all went down well with our Brownies (Girl Scouts)!

Try dissolving sugar in water then freezing it this is a solid solution. The solute is the sugar and the water is the solvent

I think you can use something called silica crystals! I know my dad us to use it when we were kids! Was great!

If you absolutely have to have it sweet then use Splenda.  It is made from sugar but doesn't have the effects of sugar.  Even sugar subsitutes should be avoid where possible because they tend to elevate you insuline.

Soda is acidic.\nGum is rubber.\n\nI don't see why not, given enough time.\nI shall approximate the time for you...1 to 2 weeks.

Hey that's worth a shot although i think ill need a couple kilo's of sugar, couple of slices of bread, some vitamin B to get the process going. but then again the carbon dioxide produced by the ferment will kill me. oh well back to the drawing board.

How about the effectiveness of different sodas on mold growing. Have you ever left a coke for a week and come back and it was molded? I've always wanted to do that project.

Sugar is sucrose, a molecule composed of 12 atoms of carbon, 22 atoms of hydrogen, and 11 atoms of oxygen (C12H22O11). \nThe 1st link is just general info, the 2nd may give you an idea for an experiment.
