A little gross but they do have others just follow the directions.
Example;
School science/Screaming jelly babies
http://en.wikibooks.org/wiki/School_science/Screaming_jelly_babies
Results
If all goes well the jelly baby will burst into flames and make a very impressive "screaming" sound as it burns to death! A smell of candy floss will also make its way around the room.

Answer 2

I did one on the effects of extreme heat and extreme cold on highp performance engine oil. The question is do national brands of oil work better than generic brands? You pick which one oyu think will work better, this is you hypothesis.I bought two national brands like Valvoline and Mobil and two generic brands, I think I used the ones from gas stations, they usually have their own brand. You are gonna need 8 plastic/styrofaom,(stryofoam works best, I think) cups and four old soup cans, and a frying pan (it doesn't have to be old, it wont get dirty) and a candy thermometer (this will get dirty) and 12 old spoons (try a dollar store or walmart, you can usually find spoons at 4 for a dollar). Make sure to label the cups and cans with the brand!! Pour about 2 inches of each liquid into seperate cups, these are you constants. Set those aside. Pour 2 inches into three more cups, set these in your freezer for about an hour. While those are cooling, pour 2 inches of each into seperate soup cans. Set teh soup cans in the frying pan and turn on the heat. Heat until the oils hit 220-230 F. While it is heating, use the spoons (seperate one for each oil) check and examine the consistincy of the oil you set aside. See how quickly it runs off the spoon and stuff like that. Take the oil from the frying pan and check its consistincy, compare it to teh corresponding oil that was sittin out. Is it the same?Or is it runnier, or maybe thicker?? Does it fall at the same rate?? Now do teh same with the oil from the freezer, do teh same tests. Car oil needs to have teh same consitency at very high temperatures and very low temperatures. If it doenst it isnt a very good or dependalbe oil. Decide which is bettter, a natioal brand or a generic brand. Thats your results. This is a good experiment adn it only takes about an hour for the actaul experiment. I won first place and went on to teh next round where I got second. Hope this helps.

I went to the book story for my daughter and got a book for science fairs it gave us everything step by step all kind of ideas from hypothesis to conclusion
