Yum, the taste of gingerbread cookies is something I definitely can’t pass up! Did you know that cookie baking is science too and also makes a fantastic Christmas theme science activity? It’s actually chemistry because a special chemical reaction occurs to give our cookies {and other baked good} a little lift. Try out this simple gingerbread man chemistry activity!


Gingerbread man chemistry Christmas science activity for kids and cookie science.

Science is fun. There are so many easy ways you can use simple science experiments to help kids explore the world around them. I am a huge believer in themed experiments too, and I know for my son they reinforce the basic concepts over and over again.

Holiday-themed science experiments including Christmas science activities can be super fun and work with what you already have. This year we are enjoying a gingerbread man theme for our science explorations including gingerbread man slime and crystal gingerbread men!



When I think of Christmas, I think of gingerbread men and gingerbread houses! Since we know baking cookies is a all about science, why not explore the chemistry in gingerbread men cookies. What makes the delicate puff of a cookie? A chemical reaction.

Christmas gingerbread man chemistry activity set up and supplies.

Set up your cookie cutters on a tray or plate to catch the mess. Add baking powder to the inside of the cookie-cutter, spreading out an even layer. Sprinkle with cinnamon to delight the senses too. Add a small container of water and an eyedropper.

Christmas science with gingerbread man chemistry experiment


Baking powder has both an acid and a base already combined. All it needs is to be moistened by whatever liquid is being added to the mix.

Baking soda eruptions need vinegar or another acidic liquid to create the eruption. However, they both let off carbon dioxide gas which causes the rise in the cookies.

Testing out baking powder chemical reaction for Christmas chemistry

Check out the reaction. It doesn’t have quite the wow factor of our regular baking soda reactions, but this is still awesome science for kids to learn about. And if you follow it up with some cookie baking, you will be their hero.

Christmas science and gingerbread man chemistry for kids


Test out different liquids. Look up recipes and see what else might used besides water. Test the chemical reaction.
