Optics and Mirrors: Challenging Learners' Illusions

by: Thomas O'Brien

Science depends on empirical evidence, logical argument, and skeptical review. Optical illusions challenge us to consider if our eyes sometimes play tricks on us. In this activity, coins dropped into a magic bank appear to shrink in size and fall through a narrow funnel into a tiny chamber or disappear altogether (depending on which type of magic bank is used). Beyond providing an insight into the nature of science, this activity serves as a visual participatory analogy to challenge the validity of the “banking” model of teaching and learning.
