Mistreatment of Classroom Animals?

I am chuffed at a recent experience.

I had multiple terrariums and aquariums set up throughout the classroom with
critters as complex as a red-eared slider and as simple as silkworms. My
philosophy behind this is quite simple: Exposure to everything and anything
offers understanding and empathy.

Imagine my annoyance at seeing the same child repeatedly attending to the
displays pounding on the glass or poking pencils through the mesh into the
living areas. Speaking to the child directly, working with his teacher, and
finally asking for a teacher-parent conference with the principal in
attendance (net-net: removal of priveleges to be anywhere near my animals)
was the escalation path.

Usually, talking to the child directly is enough but for a select few loss
of privelege or prompt denial is necessary. How can you give each child a
fuller experience without denying them an opportunity out of fear for the
animals?
