“Unless someone like you cares a whole awful lot, nothing is going to get better. It’s not.” – The Lorax, by Dr. Seuss

It’s time to warm up to worms! Did you know in ancient Egypt under Cleopatra’s rule, it is reported that anyone who knowingly killed a worm would be sentenced to death?

Composting in your classroom is easy, and you will be surprised at how little mess and odor there is! You don’t need expensive large compost bins that require lots of maintenance to keep them running. In this blog, I will show you one of the easiest and cheapest ways to create a composting system in your classroom.

You can compost without worms, however, worms are fun! Kids love them and it will ensure that the process of decomposing happens a lot quicker!

All while teaching your students about sustainability and doing your bit for the environment.

Composting Chatter

It’s important to talk to your class about what composting is and how it helps the environment. I found this really cute video on YouTube which explains, in kid-friendly terms, why it is important to compost.

We have also developed these cute posters which explain to students the compost cycle, what goes in a compost bin and how food scraps going to landfills can harm the environment.

Our Compost Bin Needs...

Warming Up to Worms

Worms are the best for composting boxes. The feeders that are used are manure worms, red wigglers or redworms. You can purchase a box of wriggly worms from Bunnings or any good hardware store.

Step-By-Step Composting Set-Up

First, you need to get two plastic tubs. Worms like the dark! So tubs that are not see through are essential! I purchased these tubs from Bunnings.

You need to make sure the gap between the top tub and bottom tub is big enough to catch all of the excess liquid and worm wee!

I popped two smaller plastic containers at adjacent corners and placed the top tub on top!

Next, you need to drill holes into the bottom of the top container, the lid and around the top edge of the container. Ventilation is crucial in this process.

The holes also allow the excess liquid to drain out!

Make sure the holes are small enough so that the worms can’t wiggle out of them!

Now you are ready to fill the compost tub with essential items to help begin the composting process.

I used soil, shredded paper, and some food scraps! Mix it all up and give it a bit of a spray with water to moisten the worms new home!

Make sure your students are wearing gloves when handling anything to do with the compost bin!

Now, slowly place the worms into their new home. Place the lid on top and let the worms explore!

Then, just add some food scraps to keep the worms happy!

Sprinkle the surface with water every other day. You want the compost to have the dampness of a wrung-out sponge.

    As part of this composting unit I'd love a professionally designed infographic about what to feed worms - I've found some online, but they tend to be very wordy and often not in 'kidspeak'. A poster that shows the best food for worms, what to feed in moderation and what NOT to feed would be great - I'm sure yours would look better than anything I can knock up! Thanks for your time Doug Klaffer
