Are you looking for another source of fun for the winter holidays? Why not add some educational science projects with a winter holiday theme? These seasonal activities and experiments will entertain you, plus you may learn something too.

Christmas Tree Preservative - You can use a little chemical know-how to keep your holiday tree fresh and beautiful. All you need are some common household ingredients.

Marbled & Scented Gift Wrap - Use a surfactant to marble paper to make your own gift wrap. You can embed a fragrance in the paper, too, so that it can smell like candy canes or Christmas trees.

Make Your Own Snow - If the temperature where you live dips below freezing, then don't settle for polymer snow. Make your own water snow!

Magic Crystal Christmas Tree - Grow crystals on a paper or sponge Christmas tree with this fun and easy project.

Poinsettia pH Paper - The colorful bracts of this traditional holiday decoration contain a pigment that you can harvest for use as a pH indicator.

Kid-Friendly Snow Globe - This is an arts-and-crafts type of project that shows even very young kids how to make their own snow globe or water globe.

Crystal Snow Globe - On the other hand, if you are more proficient with chemistry, try using benzoic acid in your snow globe. The benzoic acid precipitates into crystals that look very much like real snow.

Make Colored Flame Pinecones - Toss one or more of these pinecones onto a holiday fire to produce colored flames.

Make Fake Snow - Do you want a white Christmas, but know it won't snow? Make artificial snow!

Make Peppermint Cream Wafers - This is a cooking recipe that is written more like a chemistry project procedure. You can eat the candy that you make.

Copper Plate a Christmas Ornament - This is an electrochemistry project in which you plate a bright copper coating onto a holiday ornament. It's educational and produces a pretty decoration.

Make Snow Ice Cream - You can learn about freezing point depression or just make a tasty treat. If you don't have snow, substitute shaved ice in these recipes.

Grow a Crystal Snowflake - Crystal snowflakes make beautiful sparkly holiday ornaments. They grow overnight, so they don't take much time to make.

Cheery Colored Fire - A holiday fire is always nice, but it's even more festive if you add some color. These chemicals are readily available and safe enough for use in your home.

Re-Use the Turkey Thermometer - You don't have to throw away the pop-up thermometer that comes with a holiday turkey. You can reset the thermometer to use for other turkeys or poultry.

Glow in the Dark Crystal Snowflake - These snowflakes are cool because after you turn out the lights they continue to glow for a while.

Baking Powder vs Baking Soda - If you run out of one or the other during your holiday baking, you can substitute the ingredients. You just need to understand the chemistry of baking powder and baking soda.

Silver Crystal Christmas Tree - Grow pure silver crystals on a tree form to make a glittering silver Christmas tree. This is an easy chemistry project that makes a spectacular decoration.

Holiday Gifts You Can Make

Top Gifts Science Geeks Can Make - This is a collection of quick and easy gifts you can make using your chemistry know-how.

Signature Scent Perfume - Crafting a signature scent is a classic chemistry project.

Solid Perfume - You can also make a solid perfume, which is a convenient alternative to liquid perfume.

Fizzy Bath Balls - Fizzy bath balls use sodium bicarbonate (baking soda) to produce their 'fizz'.

Scented Bath Salts - There are different types of salts. A good scientist knows which to use to make soothing bath salts.

Festive Gel Air Fresheners - You can make your own air fresheners. You can layer festive colors and add holiday scents, too.
