25 of the Most Festive Christmas Science Experiments for Kids

If you love Christmas science experiments, this is the list for you! Kids will have a blast completing these Christmas science projects.

One of my biggest passions is bringing “boring” subjects like science and math to life for kids like we do in these Christmas science projects!

When I was a child, I HATED those subjects and would have rather written 1000 papers over doing one science project.

But when my daughter was born, she was really into science. She didn’t get that from me.

But through her, I realized that STEM activities can be fun.

Now for every holiday, we complete different STEM challenges and science experiments that fit that holiday and theme and have amassed over 25 Christmas STEM challenge ideas to try.

These are the best Christmas science experiments for kids that will keep them loving science the entire Christmas season. Make science fun again! #stemed #sterm #handsonlearning #chrsitmasactivities

Today, I’ve gathered some of my favorite Christmas science experiments that you can do in the classroom or at home with the little science lovers in your house.

And I don’t believe there is a child who doesn’t like science. She just hasn’t found the right science experiment yet!

We’ve done a lot of Christmas science experiments, but we’ve listed only our favorites below!

Why do Christmas science activities?

Christmas science for kids is for kids who already have a love of science and for those who don’t realize they love science experiments quite yet.

Science isn’t just a list of facts in a textbook, but something that actually has a lot of creativity and innovation hidden inside it.

When you do these fun and simple Christmas science experiments with kids, they quickly learn that science can not only be enjoyable, but that it is one of their favorite subjects in school.

And the more kids who are interested in science in the early years the more kids will choose science-related careers, which is a wonderful career path to follow.

If you love Christmas science experiments, this is the list for you! Kids will have a blast completing these Christms science projects.

The world needs more innovators, scientists, and creative people who aren’t afraid to fail. And it can all start with a simple Christmas science activity.

Holiday Science Experiment Tips

christmas science activities

 The best thing to stress for kids when completing a science experiment is that there isn’t a “right” answer.

Science is all about proposing, trying, and testing an idea.  

Recording results and trying again with a new twist are also key elements of any science activity.

It’s helpful when completing Christmas science projects to keep a journal of the different experiments and how they turned out.  

This will likely spark a whole list of new questions for kids and they will want to try all sorts of fun science activities.

Every successful science project includes all elements of the scientific method:  


You can’t experiment without a question. Many science experiments start with the question “what will happen when…”


This is where children determine what they think might happen.


The fun part is testing out the ideas!

Analysis and Recording

Data mining and recording results is an important part of any science experiment.


Try something different and test again!


What happened? Was it what the kids expected?
