We are creating a jellyfish in a jar preschool activity that is part art project and part science to highlight World Jellyfish Day on November 3rd. Also, you’ll love How to Homeschool Preschool and Learn How to Make an Easy Jellyfish Lights Craft.
It is a fun but simple demonstration of how jellyfish move in the water and making the jellyfish together provides the perfect opportunity to talk about its anatomy.
The best part is that you can make it with trash, well at least items destined for the trash or recycle bin.
What makes this cool science activity work the way it does?
Air is lighter than water, so any way that you turn the bottle, the head of the jellyfish will rise to the top.
Use these facts below to learn more about the moon jelly that closely resembles our jellyfish in a jar and some of the resources and activities I found to create an entire study or just a day of fun and learning.
4 Facts About Moon Jellyfish
Since our jellyfish in a jar activity resembles a moon jellyfish, we are going to swim right into it and learn all about this amazing invertebrate.
- Aurelia is a genus of jellyfish; they are commonly called moon jellies and are in the class Scyphozoa. There are currently 25 accepted species that fall under moon jellies.
- Moon jellies can be identified by four circles visible through the translucent white bell and short tentacles.
- Moon jellyfish can be found in oceans all around the world. They thrive in a warm environment and are often found near coastlines in the Atlantic, Pacific, and Indian oceans.
- Moon jellies even went into space as an experiment on the Space Shuttle Columbia in 1991 as part of a study on the effects of weightlessness on the development of internal organs in juvenile jellies.
Also, look at some of these books about jellyfish.
I always lean toward living books first, then add reference books.

Finally, look how to make this jellyfish in a jar preschool activity.
Jellyfish in a Jar Preschool Activity
You will need:
- Large clean jar
- Water
- Small plastic bag
- Scissors
- Straw
- String
- Blue food coloring
First, cut a square of plastic out of a store bag or ziploc bag that would fit inside your jar with plenty of room to move.
Cut strips through both sides, leaving a few inches uncut for tentacles, you may want to cut away a few of the strips so it is not so full.
Place a straw into the center and wrap a string just above the cuts to define the head (bell) of the jellyfish.
Blow into the straw to fill it with air. As you pull out the straw, tighten and tie off the string to keep it filled with air.
Fill the jar with water and a drop of blue food coloring.
If you add too much blue it will be hard to see your jellyfish.
Use the straw to push the jellyfish down into the jar.
Replace the lid and watch the tentacles dance around as you gently swirl the water.
To extend the activity a bit you can let your child use dry erase markers.
Use the markers on the jar to create a colorful world for your jellyfish to live in.
