Cob in the Park Field Trip

Join us in Dufferin Grove Park for a one-of-a-kind, hands-on fieldtrip where students take part in an earthen building workshop and make their own pizzas at the park’s outdoor wood-fired bake oven. Come get muddy, learn something new, and eat a delicious lunch in the park at springtime! Read on for more details. For bookings and more information please contact park staff, Amy, at or 416-392-0913.


Every Wednesday, May 23 – June 20, 2007.

The program is 1 ˝ - 2 hours, and there are three slots available each day beginning at 10:30am, 12:00pm, and 12:30pm.


We welcome groups of any age, though grades one to eight might enjoy it most.

Part 1. Building with Cob

A day camp visit last summer

Georgie Donais, the driving force behind the community cob courtyard built two years ago, will lead students in an hour long cob building workshop where they will lend a hand in the construction of the park’s cob bio-toilet. The foundation and bio-toilet were completed last summer, and now it’s time to add the surrounding cob structure. Cob is a building material made by mixing clay, sand, and straw by foot, and forming it by hand into walls. This is a chance for students to contribute to the creation of a unique, permanent addition to the park.

It is also a rare opportunity to add an interesting practical component to discussions about the environment, sustainability, and recycling. Working with cob is a way to recycle, re-using waste materials like concrete and clay to create beautiful, useful structures. Students will gain first-hand knowledge of a natural building technique which takes less of a toll on the environment than popular construction methods. They are also encouraged to pick Georgie’s brain about the bio-toilet, an environmentally-friendly waste management alternative.

Part 2. Making Pizzas

After a quick wash-up at the sinks in the cob courtyard, it’s time for pizza-making. Park staff will have the bake oven hot and ready to go, and provide dough, sauce, cheese, and herbs from the community gardens – feel free to bring your own toppings!


Cost is $5 per student, which includes cob workshop and pizza materials.

Space is limited.
