We have many new worms. We are working on a vermicomposting program at our elementary school, composting as much lunch wastes as possible. We've just begun harvesting castings. I place mound of castings on tarp. The worms all dive for cover and 5-6 children scrape off top layer and give to other children who sift it into wheel barrow using plastic seedling flats as sifters.
Unfinished castings go into a seperate bin for further finishing.
Sifted castings are used to ammend our transplanting mix or added to holes when planting out in garden. We keep magnifiers and ID books to help us identify all the creepy crawlies helping the worms.
