Kids Science Experiments in a Jar

Have a few empty Mayver’s jars laying around at home?

Put them to good use with these easy home science experiments! The best part is that using jars for experiments means low mess impact! Perfect kid-spiration for the weekend!

These experiments are not only super fun! They are also a great way to get kids thinking.

With all experiment get the little ones critically thinking about what they are actually doing and why the experiment has turned out a certain way. A great way to do this is to ask what they think will happen with the experiment a then compare it to what actually happens.

These are our 6 favs!!

Rainbow jar

With just a few common household ingredients like dish soap and honey, little scientists can actually pour a rainbow in a jar. There’s no need for any magic, just 100% kid-friendly science. This one teaches kids about the concept of density.  Click here for step by step instructions!

Cloud jar experiment

This helps visualise the concept of raining. The shaving cream represents the clouds, the water represents the air, while the coloured water represents rain. As the coloured water saturates the “cloud”, it gets heavy and eventually gets so heavy that it can no longer hold the coloured water. It “rains” down into the jar – through the “air.” Click here for the experiment!
