- Identifying mystery powders, includes a decision chart and backstory (I’m guessing Mrs. Claus isn’t very good at food storage safety). Requires basic household supplies: baking powder, baking soda, flour, powdered sugar, baby powder, corn starch, vinegar, and iodine.
- Chromatography Christmas decorations (requires coffee filters and non-permament dyes, like those in an overhead marker. I’ve even seen it done with M&M’s)
2. Â Christmas Ornament (Crystals)
A holiday variation on your typical crystal garden experiment.
3.Â Examining Snowflakes (Crystals)
This one requires children to collect snow flakes as they fall, inspect them, and record their observations. Not really an option here on the border, but maybe you’ll have a White Christmas at your house!
4.Â Old Fashioned Sponge Candy (Acids and Bases)
The combination of vinegar (acid) and baking soda (base) makes a foamy candy.
What would Christmas be like on the other planets in our solar system?
6.Â And don’t forget to let the kids help you with the baking! Cooking is full of math and chemistry, and it’s yummy, besides.
