Your Father's Nose
Source Institutions
In this fun optics activity, learners explore principles of light, reflection (mirrors), and perception. Learners work in pairs and sit on opposite sides of a "two-way" mirror.
Mix and Match
Source Institutions
In this optics activity, learners explore color by examining color dots through colored water and the light of a flashlight.
