You might be inspired by the prospect of outdoor learning, and by equipping your school grounds with a naturalized area. But hold on first:
Is your school still applying lawn herbicides to the schoolyard's grass?
If you are considering more outdoor learning at your school, consider stopping that before anything else.
Take five minutes right now to type into your search engine "lawn pesticides health" or "pre-emergent herbicide health risk" or "azatrine" or "glysophate". Spend just a little time to scan over the summaries of scholarly articles or other respected sources of information. What do you find?
To be fair, also briefly search "lawn herbicides harmless", or "glysophate risk exaggerated" or such terms, and scan any research that comes up.
Now, based on what you read, do a quick mental risk/benefit analysis on the use of herbicides for cosmetic reasons at school (or anywhere).

Does that make any sense?
I hope that this blog post will soon be outdated. I hope that lawn pesticides on school grounds, parks, sports fields and anywhere, for that matter, will soon be prohibited for the common good, as it already is in a number of jurisdictions. Children should not be allowed to play and learn on pesticide-treated grounds.
Even in tentative-sounding scholarly articles, like this one, researchers state that they are persuaded that herbicide exposure is linked to cancers, neurological impairment and reproductive/endocrine problems. 
At home, I do two things with regards to our lawn so as to not be 'that neighbor'. First, I know that aiming for a monoculture of grass is a fight against the way things were created to be, so I keep and add nice 'weeds' like Johnny jump-ups, thyme, clover, self heal and a few other blooming, spreading plants. Apparently, that's called a 'bee lawn'. But it helps not only bees: to build topsoil, more plant species above ground
equals more diversity of beneficial organisms below ground. Secondly, I choose a few weeds that I don't want (to inflict on our neighbors), like dandelions, bindweed and Canada thistle, and I spot-spray with a herbicide only those plants. Certainly that approach can be taken at schools if any weeds need to be dealt with at all. Healthy soil = healthy people.
