Why Do Fun Winter Science Experiments?
There are many benefits to completing seasonal science experiments that go beyond just viewing a science demonstration.
With fun science experiments, kids learn to view the world with curious eyes, and can discover that learning is fun.
Science is one of the best hands-on learning tools for kids, and it combines many elements of effective learning that can transcend the science lab into other areas of learning.
In a winter science experiment, kids are learning about the world and about a scientific concept. But they are also learning things like:
- How to follow directions
- How to set up an investigation
- How to test a theory or idea
- How to think logically about a problem
- How to come up with solutions to a problem
- How to make changes to a process along the way
- How to prevent frustration when something doesn’t go quite right
Kids also learn creativity and critical thinking skills in the science classroom that are useful anywhere in life.
So if you’re ready to get started with these fun winter science experiments, keep reading!
The Ultimate List of Fun Winter Science Experiments in Jars!

If you have a jar, you can do these fun winter science experiments in jars. Kids of all ages will love these wintery science experiments.
In just five seconds, kids can make ice! How does it work? In this experiment, kids learn about molecular bonds, the freezing point of water, and how crystals form.
You can make a blizzard in a jar! This super fun winter experiment teaches kids about chemical reactions, gasses, weather patterns, and more!
If it’s not cold enough outside, you can make it cold inside by making frost in a jar. This science experiment teaches lessons on freezing point, condensation, the melting point of ice, and weather.
In this winter slime experiment, kids can learn about polymer chains, chemical bonds, states of matter, and non-Newtonian fluids all while having fun playing with slime!
Kids will be amazed that they can make an ice-like substance without any cold temperatures at all. Learn about chemical reactions, states of matter, crystal formation, and more in this fun experiment.

Nothing is more fun than snowflakes during the winter. Make your own in the borax crystal snowflake experiment. In just a couple of hours, transform borax powder into glittery snowflakes.
Making a snowglobe is a fun way to celebrate the wintery season. While making the snow globe, learn about solutions, reactions, and the scientific method.
Burning Ice Science Experiment
In this science experiment, kids determine if it is possible to get ice to burn (safely), and how to do it. This experiment should only be done with close adult supervision.
Freezing Oil and Water Mixing Experiment
In this winter science experiment, kids determine if freezing oil makes it easier or harder for water and oil to mix.
Make slime with a wintergreen scent and learn about polymer chains while smelling amazing!
