For Earth Day – A Chance for Environmental Custodians to Show What They Know

Knowing that I have a worm composter in my kindergarten classroom, two girls (grades 1 and 2) came up to me last week as they walked in from recess holding a bucket of earthworms. A bucket. Full of worms.

They asked me if they could join these worms with the ones in my classroom, and I had to tell them, “No”, that just as there are different kinds of fish or dogs in the world, so are there many different kinds of worms, and these two kinds were very different, not to mention the fact that the worms in the bucket had been born in the wild and that is where they should remain. The students were a little disappointed by my answer, especially after all their hard work delicately harvesting about 2 cups of worms, so I suggested that they could introduce them into the gardens in our courtyard (outdoor) classroom. The girls headed into the courtyard, found a spot near a tree and gently dumped the contents of the bucket on the ground. They were very proud of themselves and told me they knew about how worms help us so they felt that they had really helped the worms, too.

While I was on lunch duty in their classroom a while later, the girls were still eager to talk to me about the worms – evidently, the vermicomposter makes me some sort of expert in the way of the worm. Anyway, they told me that they were just getting started. The girls had BIG PLANS. They wanted to start their own Worm Care Service, since they know exactly what worms need. “Great!” I said, as I realized what a great inquiry-based learning opportunity this was, “Maybe you should make some posters and business cards telling people what it is you do.” This got them even more excited and they wanted to get down to work as soon as they finished eating. Even though selling a worm care business may not be a realistic venture, there is the fact that the girls could at least have an opportunity to share their knowledge about worms. And that is how the idea of a Children’s Fair to showcase students’ environmental interests and projects has come to be added to this year’s Earth Day Celebration. Being the first time at my new school, it will start out with just one or two tables, if we’re lucky, showcasing students and their nature-conscious projects and hobbies. The Fair is open to grades 1 to 6, and all the students will get a chance to visit and ask questions and learn from each other.

Having done something like this last year at my previous school on Earth Day, I had forgotten how rich an experience it was for the students involved. I realized afterwards that it had been so successful because it was an opportunity for students to do something at school which had no rubric or assessment attached to it, and for which they were highly motivated. Last year, all I did was call a meeting together asking students how they would like to participate in the Earth Day Celebration. That’s when things just started to morph into them wanting a way to share their knowledge or expertise about the environment. At the meetings, there were lots of ideas and “Can I…?” questions. In the end, not everyone was ready to set up a table with items and information, but at least it got them to consider the possibility that something they know or do could be of some interest and value to their peers and the adults in their life. This year, I don’t know what expertise we will showcase, but If someone has a feather or rock collection they are proud of, if they know how to fold newspaper into compost bin liners, or if they know how to make bird calls or care for worms, then the Children’s Fair is the place to show what you know.

Kinders as Enviro-Experts

A couple of months ago, I got the idea into my head that we should have an Earth Day Fair at our school. I found it frustrating that although we touch on aspects of sustainability and respect for the environment in the curriculum, when it came to Earth Day, saying “Happy Earth Day!” over the morning announcements, was pretty much as far as it went. I happened to mention it to the principal one day, and she said, “Got for it!”. So I started to put more ideas together and tried to figure out how I could also bring my kinders into the mix, not just as participants, but as leaders.

Time passed and things slowly came together. We held our fair  in the morning, indoors, where tables were set up with various presenters to showcase their eco-friendly projects. In the afternoon, the whole school was invited to participate in a variety of eco-friendly activities in the school yard. It was marvelous!

Generally speaking, kinders are often not invited to participate with the general school in certain events due to their young age and somewhat shortened attention span. With the Earth Day Fair, however, I was willing to try out having a table set up, just like the big kids, where kinders could share their knowledge of the worms we have in our vermicomposter.

I decided to follow the science fair model of having a tri-fold poster board for all our information, some literature about worms, the things we need to prepare the compost, and the worms themselves for our information table. In the weeks preceding the fair, I invited students who were interested in showing what they know about worms to a table with pencils and paper and the tri-fold board already set up. I divided up the board into three sections I knew my kinders could elaborate on in order to be able to teach others about vermicomposting;

  1. All about Worms
  2. How to Compost
  3. Why is it important?

There were 8 students who showed an interest – reviewing the books and looking at pictures (some even reading – “Madame! Look! It says here that worms can push ten times their weight!”); who wanted the challenge of writing and drawing their information; and who stayed and observed and asked more questions whenever I would open the compost bin to feed or check on the worms – and so they became my Worm Experts. Because they contributed to the poster display, they were the right people to represent our vermicomposting table at the fair. They were so excited!

I was there to supervise while the Worm Experts had the responsibility of answering questions. Students and staff who visited the display learned a lot as the kinders presented anatomical drawings they had made of the worms, delighting in stating that worms have 5 hearts. The Experts also explained that worms need to stay slimy or they will die, because they breathe through their skin. The composting they explained in three easy steps; collect compost, blend the compost, feed the compost to the worms. Finally, they stated that worms are important because when they dig tunnels, their poo becomes soil with nutrients that helps plants grow. 

The Worm Experts answered questions for the better part of an hour, with the whole school filing past to visit the display. With their enthusiasm beginning to fade a bit towards the end, I asked if any of them would like to stay at the fair or return to the classroom. Half of them decided to return to the classroom because “Being an Expert is hard work.” The others who were happy to stay, chatted with other presenters or went and visited other displays with grade 6 Big Buddies, just like the big kids.
