Light, Reflection, and Vision

A Grade 4 science course about how eyes use light, how mirrors reflect light, and how transparent and opaque materials change what we see.

Light, Reflection, and Vision

Course overview

This course teaches Grade 4 students how light helps eyes see, how mirrors reflect light, and how different materials change shadows and visibility. Students use simple science words to explain what they observe and to test ideas with everyday objects.

What students will learn

  • Explain how eyes use light to see.
  • Describe how reflections work in mirrors and shiny surfaces.
  • Tell how shadows form when light is blocked.
  • Sort materials as transparent or opaque.
  • Plan a simple investigation about light and materials.

Lessons

Parent guide

Use a lamp, a mirror, a window, and everyday household materials to make the ideas concrete. Ask your child to explain what the light is doing, what the eyes can see, and how the material changes the result.

Completion

A student finishes this course when they can explain how light helps us see, describe a reflection, and compare transparent and opaque materials in a simple investigation.
