Explore Christmas Theme Science

I am really excited about our Christmas advent calendar this year because I wanted to make it simple and fun but still a great hands-on learning experience. Fun holiday science themes make it extra special.

You already will have most of the supplies on hand for these min Christmas baking soda eruptions! Your kitchen is a great place to learn about science!

Test it out! Baking soda science activities are always a hit with kids because of the wow factor! The bubbling, erupting, fizzing concoction is such a rewarding sensory experience.

Adults love it too. Not only are our mini Christmas baking soda science eruptions a cool activity, they are also science!

These easy mini Christmas baking soda science eruptions are perfect for an afternoon activity. You can really use an colors you like, but red and green is our choice.

All Kids Can Be Scientists!

So what exactly is a scientist? How can you encourage your kids to be scientists without a lot of effort, fancy equipment, or complex activities that create confusion rather than curiosity?

A scientist is a person who seeks to acquire knowledge about the natural world. Guess what? Kids do that naturally because they are learning and exploring the world around them. All that exploring brings up a lot of questions!

A good scientist asks questions and makes observations as they explore the natural world, and we can further encourage this with simple science experiments. Knowledge is gained through all of these questions, explorations, and discoveries! Let’s help them by providing fun science activities that spark their inner curiosity.

This Christmas baking soda experiment is quick and gives kids that instant gratification they so crave! Being curious, trying different theories, investigating, and exploring are all critical in science. Not every science experiment needs to be deep and probing!

Making mini erupting volcanoes is a perfect kitchen science activity for Christmas! It is fun to explore and observe, and the setup is simple enough for busy families and classrooms to fit into the day.

Helpful Science Resources To Get You Started

Here are a few resources that will help you introduce science more effectively to your kiddos or students and feel confident when presenting materials. You’ll find helpful free printables throughout.

How Does A Baking Soda and Vinegar Reaction Work?

An acid-base reaction occurs when baking soda (sodium bicarbonate) and vinegar (acetic acid) combine. The vinegar is an acid, and the baking soda is a base.

When they are mixed, the acid and base react, producing carbon dioxide gas. The release of carbon dioxide gas creates fizzing and bubbling, making this reaction visually exciting.

Supplies:

  • Small Clear Cups (or cookie cutters)
  • Vinegar
  • Food Coloring
  • Baster or Eye Dropper
  • Glitter
  • Tray

Set-Up

STEP 1. Set out a tray to catch the fizz! This mini Christmas baking soda eruption can get a little messy! It is an eruption, of course.

STEP 2. Place as many cups as you like on the tray.

STEP 3. Add baking soda {1/2 tablespoon or so} to each one.

STEP 4. Add a few drops of food coloring to each one and sprinkle with glitter.

STEP 5. Set out a bowl of vinegar and an eyedropper or baster. Use the baster or eyedropper to squeeze vinegar into the cups and see what happens!

Try this with plastic ornaments! Take a look at our erupting Christmas ornaments setup.
