Looking For Looking For Snails For Elementary School Project (lafayette / orinda / moraga)

I run an after school program for Elementary School aged children.
Currently, we are planning a project centered around exploring the life cycle and behaviors of garden snails.
We believe that observing these creatures up close will not only spark curiosity but also deepen our students' understanding of biology and ecology.
If anybody has these pesky pests in their garden I would be glad to take them off your hands!
