One of my favorite tools for doing science and STEM is a simple glass jar (you can also use plastic with younger kids!).
Jars are perfect for measuring, experiments, and all kinds of learning, and their clear apperance makes it easy to see reactions!

How I got into mason jar science experiments
When my oldest was four, I wanted to help her learn to love reading.
I got out all my favorite books, many of which had fantasy themes.
But she HATED those books.
I was confused. What kid doesn’t like fantasy books?
So, I took her to the bookstore and let her pick out the books.
She picked books on animal science, weather science, and chemistry.
Science was my most hated subject in school, so I was in trouble.
How could I foster her love of science when I didn’t know much about science?
After thinking a while, I realized we could do fun science experiments together. She’d be learning, and I’d be learning right along with her!
I didn’t have any formal science equipment, so I used what I had. Which happened to be mason jars. So, we started doing Mason jar experiments!
Now, we have the Jarring Science Club so you can do your experiments in jars, too!

Why Do Mason Jar Science?
Today, science experiments for kids are more important than ever.
Science and technology are huge parts of our world today, and the future will be even more science and tech-focused.
Kids who aren’t immersed in the world of science and STEM exploration from a young age will be left behind their peers, and may struggle to find work in the fast-changing landscape of future careers.
The simple science experiment that a child does today may spark their desire to discover something that will change the world in the future.
Every day, young children are using science experiments to solve real-world problems in medicine and technology that have never been uncovered before.
And all these scientific discoveries start with a firm foundation in science and STEM.

WHY DO SCIENCE IN MASON JARS?
You certainly don’t have to use mason jars for science. We’ve also used pickle jars, olive jars, jelly jars, and baby food jars.
But the main benefit of using a mason jar for science is that they are glass. Plastic isn’t a suitable material for many science experiments, because it can warp or melt.
Glass, on the other hand, is what most science equipment is made of and creates purer results.
THE MASON JAR SCIENTIFIC METHOD FOR KIDS
Every science experiment contains four elements:
Kids should start every science experiment with a question, even if that question is just “what will happen?”
Before doing any experiment, children should record what they believe will happen.
This is where the fun part comes into play. Test the hypothesis to determine if it answers the question fully.
A Recording and Analysis
As the test is completed, record what happened and analyze why.
Try different variables and try a new test to see if the original answer is confirmed or disproved.
