The Wonder of Worms
We are wrapping up our science unit on Ecosystems before the upcoming break and today was a day we had eagerly anticipated- we were getting worms!
We have talked abut ecosystems and learned about the interdependence of the components of ecosystems. We have visited the rain forest and seen nature up close. We have observed plants and experimented with taking away one of their needs to see how they coped. But today, we got worms.
Last week we knew we had to prepare, so we started shredding newspaper and cardboard (yes, the worms will eat this to start composting). On Monday we were excited and ready, but got word at the last minute that it was postponed for a day. Finally Tuesday arrived and when the students saw me they asked, “Are the worms here?”
I explained that I was not the ones bringing the worms, but that Ms. Nisha was due to arrive shortly and after Morning Meeting we would go to the science lab to wait for her. While we waited we read Wiggling Worms at Work to give the students some background knowledge.
When Ms. Nisha arrived the students were so excited. We teachers worked with her last year, so knew what to expect, but she had definitely improved her already strong presentation. She talked to the students about the need for sustainability and explained what that meant. Our school really promotes this, so the students were fairly knowledgeable.
She then showed them her model of what they would see if they were underground and talked about the worm bin ecosystem.
Then we were ready to meet our new friends. Many students wanted to hold the worms and it was quite fun to see them wriggling around.
Then we built their “bed” by putting in some torn cardboard and shredded newspaper, which was then sprayed with water. Next Ms. Nisha took out about 50-60 red worms from her worm bin to share with us. A few food scraps and an explanation of surface area for eating and the worms were fed. Finally, we took a good look again and our worms were in their new bin (we requested that the inner bin be see through so that we can pull it out and do some observations).
The students were so excited and had learned quite a lot. They were eagerly discussing who could babysit them over future school holidays and the recesses they would want to miss just to watch the worms. I love that these students get to have experiences like this and know that they will be problem solvers now and in the future as they become more aware of choices they can make to live more sustainably.
