This week we have been learning more about the Jellyfish. One important fact we learned was that the jellyfish is now called a sea jelly. Just like starfish are now know as sea stars, jellyfish are now known as sea jellies. Why the switch? Jellyfish aren’t actually fish, making the name sea jellies more accurate. It will be hard to make the switch because we have been calling them jellyfish for such a long time, however we are going to do our best.
After learning all about sea jellies we thought it would be fun to make our own to keep in the classroom. If you would like to make one at home this is what you need:
- a clear plastic bottle
- string or a rubber band
- a plastic shopping bag
- a few drops of blue food colouring
Here’s what you do:
Cut the handles off the shopping bag so you have a plain square of plastic. Tie a section off with the string (or rubber band) to make the sea jelly’s head. Cut the remainder into strips for the sea jelly’s tentacles. Put the sea jelly into the empty bottle. Fill the bottle with water, add a few drops of the blue food colouring. Squeeze the bottle or tip it upside down to watch it swim up and down the bottle.
