I did it in fifth grade with some help from my dad and got an award. There are many books in the library about how to "make a circuit that will turn on a light. so basically it is an experiment on electricity. Get a small battery a bit bigger than used in a remote control car and attach it to a board. I used wood plyboard but it was heavy. on the other side is a regular15 watt light bulb and wire connectors. Basically you allow the judges and others to try their hand at your experiment once you are done. the open wires are alternately pressed to anything you can think of: paperclip, plastic spoon, penny or other coin money, a piece of apple, a pencil, a piece of potato, etcetera.
Of course the circuit will be filled by any metal object and your light will go on. But the high starch content of the potato will also run your light bulb!
Your hypothesis will simply be to see what sort of items will conduct electricity.

My little brother mixed sugar and water together then filled different bottles with the mixture. He laid a pencil across the top with a string tied from the middle and a weight on the bottom the string. He then stuck these bottles in different places to see if different amounts of light affected the size of the crystals that grew on the string. He also wanted to try different mixtures but hasn't had the time yet. Have fun! Good Luck!

Compare melting times of cheese. I did this in seventh grade, but it is fine for sixth graders. Have them research cheese and why one cheese would melt faster. The answer is that cheeses with longer aging times take a much longer time. GOOD LUCK!

Yea Im doing a science project too. Im seeing if plants do better without sunlight or with and also if they do better with little amounts of water or lots of water.
hoped that helped! :) oh I asked my teacher if that was a good idea to do and he says "Yes."

google "freezing hot water"
it's a neat test which tests whether or not hot water freezes faster than cold water...
Sounds like a no-brainer, however, it is actually tricky
