Baking soda and vinegar science experiments are always a huge hit with my preschoolers. No matter how many times we make a volcano erupt, they keep begging to do it again and again. Snow Volcano Winter Science Activities for Preschoolers are a great way to take advantage of the snowy weather and take science learning outdoors!

Recommended Grade Level:

Materials for the Snow Volcano:

  • Vinegar
  • Dish Soap
  • Baking Soda (Bicarbonate of Soda)
  • Red Food Coloring, Orange Food Coloring (or a color of your choice)
  • Spoon
  • Cup or Plastic Bottle
  • Squeeze Bottle
  • Snow

Don’t get me wrong, we love playing outside in the snow, making snowmen, throwing snowballs, and creating snow angels, but every once in a while we like to mix it up and find a new and exciting activity to do!

All your snow loving kids who love science will be excited to create a volcano and do this winter science project for preschoolers.

Baking Soda and Vinegar Experiments For Preschoolers:

Vinegar and baking soda science experiments for kids are not only super fun to watch, but can be used to introduce a variety of science concepts to children.

Snow Volcano Activity for Kids

This snow volcano science experiment is a wonderful way to introduce chemical reactions.

Creating volcanic eruptions with baking soda and vinegar can be a good experiment for a solid, liquid, and gas unit.

Simple science experiments like this cool winter science experiment are also great ways to teach about the scientific method and about science experiment safety!

A Step-by-Step Guide On How to Make a Snow Volcano For Kids:

Instructions for the Snow Volcano:

Make a Cone:

Use your scoop or a small shovel to create a pile of snow. Form the snow into a volcano shape using your hands.

Scoop out the middle and place your cup inside the center of the volcano.

Repack the snow around the cup and fix your volcano shape if necessary.

How to Make a Volcano Erupt (With Baking Soda & Vinegar):

Put 2-3 tablespoons of baking soda into the cup. Add 1 teaspoon of dish soap and a few drops of food coloring to the baking soda.

Using the squeeze bottle, pour vinegar into the cup. Watch as the mixture begins to react and overflow causing a snow volcanic eruption to mimic a real volcano!

Continue to add vinegar to create new bubbles and watch your volcano erupt over and over again! Enjoy the fact that the mess is outside!

Observe Science:

What did you observe in the volcano experiment?

The baking soda (bicarbonate of soda) and vinegar reaction inside of the volcano causes a chemical reaction and the ‘magma’ from inside the volcano explodes from the top of the snow volcano.

Children can watch the lava flow down the volcano and follow the path that the lava makes down the ridges and valleys of the volcano.

Using red food coloring or orange food coloring in the white vinegar makes the reaction more visible against the white snow.

What will children learn from this snow volcano experiment?

The Science Behind the Volcano Eruption Experiment

According to Britannica Kids

“Mixing baking soda (sodium bicarbonate) and vinegar (acetic acid) causes a chemical reaction that produces a salt (sodium acetate) and water, as well as carbon dioxide gas.”

FAQs About Snow Volcano Experiments (Frequently Asked Questions)

What is a good hypothesis for a volcano project?

Every science experiment starts with a hypothesis. A hypothesis is a statement that can be proved or disproved. It is typically used in quantitative research and predicts the relationship between variables.
Example:
“Combining baking soda and vinegar with cause a reaction that looks like a volcanic eruption.

How do you make a volcano erupt without vinegar?

You can use another acidic liquid instead of vinegar to create a similar reaction, such as lemon juice or orange juice.

Can you make a volcano with lemon juice?

Yes, you can replace the vinegar in this experiment with lemon juice to create a similar reaction. Results will vary based on the strength and quantity of the lemon juice.

Other Ideas For Your Baking Soda Volcano Science Activity:

  • Don’t currently have any snow where you live? Try this fun play dough volcano!
  • If it’s too cold outside, bring snow inside and use a shallow clear bin or craft tray to create your volcano inside.
  • Research and look at pictures of different types of volcanoes (shield, cinder cone, composite, lava dome) and have your child create the four different shapes in the snow.
  • Take pictures of the experiment and create a scrapbook page or science journal page about your experiment.
  • Use a small beaker and a balloon when you do a baking soda and vinegar activity for preschoolers to show how the carbon dioxide will blow up the balloon.
  • Try this fun apple volcano science experiment!
