It's spring! Many of us have been in the gardens and getting plant projects ready with kids. It's also a great time for worm education! A in-depth discussion about such a small critter on the farm is a great puzzle piece for larger conversations with other plants and animals. This year we made this 'puzzle' worm I photoshopped it together for the document I am sharing below. You can cut out and use the element pieces (oxygen, food, and electrical signals) to ask a child to trace the movement through the worms systems.
What really started this project was my class of fairly educated students who maintain a worm food waste system, said they believed wholeheartedly that if they chopped an red wriggler from the worm bin in half both halves would grow a new worm (like the flatworm dissection) and we could double our worm bin population. This allowed them to see that important functions within a worm that keep it alive.
My file has the name of some of the body parts common in earthworms. This artwork is a very simplified worm and more detailed sketches and images can be found on the internet. You and your crew can make your own worm puzzle (we used poster paper, paint, and markers, then cut out the pieces and laminated them together) and pick and choose which structures and systems to focus on.
