Mt Vernon Hamilton first graders examine the role of worms in the environment

Nothing is more fun than going into a classroom with a worm bin and teaching first graders about how every living being has a really important job to do.

Picture1The initial reactions of the little ones is a long drawn out “uuuhhhhh”, when I show them pictures of my worms and tell them how much I love them. They usually look at me with disbelief. And then they learn about all the fabulous things that only worms can do for us, and without that, our world would truly be in dire straits.

Students learned how worms breathe and upon learning that it is through their skin, they all rubbed their arm in disbelief. They learned about the function of muscles and it was very cute to watch them flex their biceps repeatedly, imitating contraction.

They learned about how much worms can eat, how they are the cleaning crew of our world. As they are translucent, one can actually observe the castings ( worm speak for “bathroom business number 2”) pass through their body and students learned how they are connected to healthy soils and plant life. I was blown away that all students knew that plants gave us oxygen (yes they used that word!) and food.

They learned how worms reproduced and all were very busy looking for cocoons and to identify what age a worm might have based on its size. BTW, just in case the intrepid reader wants to know. Worms have both male and female organs, but two worms still need to mate, and then both can have about 5 cocoons per week. Each cocoon contains  2-3 itsy bitsy live worms, that will stay for about 45 days in the cocoon until its time to hatch. It takes 6-10 weeks to grow to adulthood and they have a lifespan of 3-5 years (quite astonishingly long)

The lesson was capped with a wet paper towel in front of the kids, with a handful of worms on it to get up close and personal with them. Students learned that every living being has an important job to do and deserve our respect.
