example: christmas ornaments with elements on them.

Last year my nerdy friends and I made Christmas ornaments out of test tubes. We got ahold of some stuff called Tollen's reagent that's used to perform the "silver mirror test". That's used to distinguish between aldehydes and ketones because mixing Tollen's reagent with an aldehydes causes it to coat the vessel like a silver mirror, but nothing happens with ketones. We mixed the Tollen's with an aldehyde and shook the test tubes until the mirrors formed, then decorated them.

While this may be slightly dangerous (the liquid is non toxic but stains PERMANENTLY), you could do a project on bubble lights! You could explain how the crystals in the bottom of the tube react to the solution (to cause the bubbling) when they are heated by the bulb, as well as any other chemical reactions that occur.
However, you will not be able to find out exactly how they work for the same reason that no one knows how to make Krispy Kreme donuts - it's a secret!

Totally kewl! Demonstrate how to make peanut brittle. Use clean beakers and other glassware. Use the chemical names for the ingredients such as sucrose for sugar, partially hydrogenated vegetable lipids for margarine, etc. Also use metrics for your measurements and temperature. While cooking,
explain all the chemical processes that are taking place.
Another idea is to take pine cones and dip them in watered down Elmer's glue. Then sprinkle them with NaCl, CuCl2,CaCl2, etc. Same salts you use in a flame test lab. When they are dry put them in a basket with a Christmas ribbon. They make a great gift. When they burn in the fireplace the flames will flicker in different colors just like in the flame test only more so because you have used more salt.

The water going into a Christmas tree has a type of reaction. Using hydro-energy and photosynthesis it creates energy.
Also in Christmas lights phosphorus-gas and magnesium-gas are always in a bulb. When the electric current (oxidizer) mixes with them the gases expand and create light. Same thing with a match because it also has phosphorus.

How about making Ice crystal ornaments??

Design a solution which, when added to the Christmas tree's water supply, will make the tree less flammable.

You could study snow. Like the crystalization pattern of water when it freezes making a snowflake.

how about you take your balls and freeze them in ice and then take it to school and melt it then you can say that the reaction was endothermic becausethe ice melted and then your balls warmed up which is exothermic which means you absorbed heat

Make your own fake snow that won't dissolve or poison anyone.
