One of the most fascinating things about science activities for kids has to be the ease in which you can set so many up, even at home! The one thing that all of these science experiments have in common is that they can be easily set up in a mason jar. How fun is that? Science in a jar is a super fun way to get those kiddos engaged in easy to understand science concepts using a simple mason jar.
FUN SCIENCE EXPERIMENTS IN A JAR!
SCIENCE EXPERIMENTS IN A JAR?
Can you do science in a jar?
Is it hard?
What do you need to get started? How about a mason jar! It’s not the only supply, but it will get kids asking what the next science in a jar experiment you have waiting for them!
Here are ten of my favorite mason jar science experiments for kids that are totally do-able and make sense!
TRY THESE MASON JAR SCIENCE ACTIVITIES
Click on each link below to see supplies, set up and process information as well as quick science behind the activity information. Also, grab our free mini-pack which shares the science process in a fun and digestible way for young kids as well as a journal page you can pair with each activity for the older kiddos.
These are science activities for kids that work well with many age groups from preschool to elementary and beyond. Our activities have also been readily used with special needs groups in high school and young adult programs! More or less adult supervision depends on your kids’ abilities!
Grab a mason jar and let’s get started!
Tip: Dollar stores and grocery stores both carry mason jars or generic brands! I highly recommend having six on hand but one will do fine as well.
MAKE RAIN CLOUDS IN A JAR
Explore clouds with easy to set up rain models in mason jars! One cloud model uses a jar and a sponge, another uses shaving foam! You can even make a cloud inside a jar or a tornado. Basically, you can explore a bunch of weather science activities using a mason jar.

MAKE A RUBBER EGG IN A JAR
Grab a jar, vinegar, and an egg to make the classic bouncy egg or rubber egg experiment. It’s one of the coolest experiments to set up with the kiddos because it’s a raw egg with a dissolved shell that actually bounces. This egg and vinegar experiment is sure to WOW!
CREATE OCEAN LAYERS IN A JAR
Have you ever explored the 5 unique layers of the ocean? Did you know you can recreate them in a jar and explore liquid density at the same time? It’s a very fun way to not only explore marine biomes but also explore simple physics for kids! You can also try this non-ocean theme liquid density jar activity.
Also, try creating ocean waves in a jar!
HOMEMADE LAVA LAMP IN A JAR
A mason jar is a really great option for setting up a homemade lava lamp science activity. Simple supplies that include water, cooking oil, food coloring, and generic (or regular) Alka Seltzer tablets. You can redo this one over and over again in the same jar so stock up on tablets.
MAKE HOMEMADE BUTTER IN A JAR
Get shaking! You are going to need strong arms and maybe several pairs and a good 15 minute stretch of time to turn cream into whipped cream and finally into whipped butter and then solid butter! All you need is a mason jar with a lid and cream!
FIREWORKS IN A JAR
Fireworks aren’t just for the sky or for a holiday! Recreate your own version of fireworks in a jar with food coloring, oil, and water. A fun lesson in physics that will be eagerly enjoyed by all kiddos!
DIY ROCK CANDY IN A JAR
You’ve bought rock candy from the store before, but have you ever grown your own sugar crystals in a jar? Well, all you need is a mason jar, sugar, water, and a few other items to start making rock candy in the kitchen today. This will take a few days, so get started today!
EASY GLITTER JARS
DIY glitter jars, sensory jars, or calming jars all have one thing in common! A jar! You can use any kind of bottle or mason jar to make these gorgeous, sparkling, glittery jars.
GROW CRYSTALS IN A JAR
Borax crystals are a classic science activity that actually does best in a glass jar such as a mason jar. You’ll get better crystal formation with glass than plastic! All you need is a jar, water, borax powder, and pipe cleaners.
WATCH CORN DANCE IN A JAR
Is it magic? Maybe just a little at least in the eyes of the kiddos. However, it’s also a bit of chemistry and physics too. Popping corn, vinegar, and baking soda is all you need to get started, and you’ll also find an alternative method included as well.
SET UP A SEED JAR
One of my all-time favorites, a seed jar! Grow seeds in a jar, identify the parts of a plant and get an underground look at the roots! This one is a great project for everyone to enjoy. Put it on the table and use it as a fun conversation starter too.

CABBAGE PH EXPERIMENT
In this chemistry experiment, kids learn how cabbage can be used to test liquids of varying acid levels. Depending on the pH of the liquid, the cabbage turns various shades of pink, purple, or green!
