Food Scraps Restaurant
A worm farm or compost bin is kind of like a restaurant:
The restaurant has a menu which is the food scraps that can go in the worm farm or compost
The restaurants has waiters that serve the food or in your case – the students who put food scraps in the worm farm/compost
The restaurant has delicious food which is the soil or fertilizer that is produced by your compost/worm farm system.
If your school has a compost bin or worm farm, a fun and creative way to educate your school community on the proper use of the system is to compare it to a restaurant!
