I recently heard mention in a podcast (was it a
Geoff Lawton interview?) of a permaculture textbook that's widely used in Australian schools. I'm in Australia, and have kids in primary school, and I have no idea what it is or what it's called! In fact, I found this forum
thread while searching for it
.
I suspect it may be the Stephanie Alexander Kitchen Gardens Program (
https://www.kitchengardenfoundation.org.au/). She has been instrumental in helping to set up hundreds of school gardens, and has published an excellent book called Kitchen Garden Cooking With Kids. It ties the garden and kitchen together, explains the seasonality of all the different fruits and vegetables, and is full of really well thought out recipes that primary school kids can make.
Some other resources I came across that you might find interesting:
A paper from the NSW Education Department, called "A food centered curriculum: How permaculture taught through school kitchen
gardening can lead to more
sustainable schools and communities and a more sustainable future":

Let me know if you find anything else interesting! I'm working on getting a permaculture garden set up at my kids' school.
