Why Do Science Experiments in Jars?
You may be wondering?
Why are science experiments in a jar a thing?
Well, mason jars are typically made of glass. This makes them similar to science flasks and beakers- except, that most of you have at least a few mason jars in your house.
So, a jar is the perfect starting science tool for children just getting into science who may not have a full set of “official” science tools.
With mason jar science projects, children can get started with science right away, and they don’t need to get any special tools.
As a parent, it’s nice to have a list of screen-free activities that you can offer up to kids when they declare boredom, as is inevitable during summer and other school breaks.
And as a teacher, mason jars are easy to use in the classroom because they are less expensive than “real” science tools and you can even ask parents to donate mason jars to use in the classroom for science experiments.
You can teach everything from geology to chemistry in a jar- and even learn about space in a jar, too!
What do you need to get started with science experiments in a jar?
You don’t need much to get started with science experiments in a jar! Just a few things, like:
- Mason jars
