This is a great opportunity to help students self-reflect.
The idea of an iceberg came from a popular Challenge Day exercise where students think about what it means to live "above the water line," and stop hiding who they really are. We want to be comfortable in our own skin, because that is where we can feel true peace and happiness.
On this paper, students write what other people see (top of the iceberg) and what they hide (bottom of the iceberg). This can be an emotional activity, so be prepared for a longer session, if needed.
