Fool Your Vision to Find Out How It Works
- Understand the main components of the visual system and how they work together.
- Formulate and defend a hypothesis based on experimental evidence for illusions created by fatigued sensory cells or for optical illusions created when the two eyes look at a different object.
OverviewHow is it possible that our eyes can see things that are not really there? In this fun lesson plan, your students will explore how our vision works with the help of two short experiments that involve some fascinating optical illusions. Let your students discuss why they see a hole in their hand, or why they see colors that were never there, and let them construct their own explanations.
