“Once the critters are stuck to the agar agar and the lid is on the dish, it’s pretty safe.”
I’ve also taken microbiology, and yes, the cultures in the dish are probably not what you need to be worried about. What you need to be worried about are all the other contaminated equipment and surfaces that you are going to come into contact with. I doubt an untrained child is going to know they have to sanitize everything with phenol every time they are finished, or that simply washing stuff in the sink is not going to sterilize it properly.

That’s why I always wiped my equipment off on the back of my pants after washing....
