Knowledge_On-The-Go_Grade-4Level 4 Module 4 Lesson 3: Light rays 

In Lesson 3, students build on their Level 1 understanding about the role of light in sight. Students explore patterns (CC.1) of how light rays reflect off mirrors and opaque objects (PS4.B) to deepen their understanding of how light enables objects to be seen. This allows them to begin to answer the Phenomenon Question: How do we see objects in the classroom?
