Walking into a classroom of 1st graders, armed with a bin of worms is a fun thing. Students usually squirm a bit, are slightly afraid and timidly even voice that feeling, but in general, get engaged very quickly to learn about why wriggly, slimy worms are so important to our world.
Students learn that worms are living beings that breathe through their skin. I enjoy watching them looking in disbelief at their skin trying to grasp the concept. Worms can eat enormous amounts , half of their body weight every day. To demonstrate that to the students I have them get up and put their hand at slightly above their waste and ask them to look down upon their legs and to imagine to have THAT much to eat every day.
After learning how they move, what muscles can do, how worms reproduce (by laying cocoons that contain 2 to 3 live worms, just in case the intrepid reader of this post was interested in these details), students had a chance to get up close and personal with a handful of worms.
Checking out to see the castings in the translucent tail sections of the worm gave way to great excitement and when we found the mother load of cocoons, the students were beside themselves with excitement.
Teaching students that every living being has important jobs to do and without these jobs done, everybody is in trouble is an important life lesson for kids to learn. All worms ended up with names. Jeffrey seemed to be the favorite. Students wrote afterwards what they learned about worms and they all agreed that worms are our friends.
