How the Eye Works, Eye Anatomy

Students will make a model that light reflecting from objects and entering the eye causes objects to be seen. They will understand that once that information is taken in, the brain needs to process it. This resource addresses the NGSS standards for 4th grade 4-PS4-2, 4-LS1-1, and 4-LS1-2. This resource also addresses NGSS Waves and Their Applications and From Molecules to Organisms: Structures and Processes.

This resource includes:

  • nonfiction articles
  • response pages
  • hands-on inquiry-based lessons
  • Interactive Notebook Flaps

Teachers Love This Unit!

Margaret ⭐️ ⭐️ ⭐️ ⭐️ ⭐️ Extremely Satisfied I love the detail that my students had to pay attention to throughout this resource. They learned many concepts about the eye. Love this resource.

NGSS Standards Addressed:

✅ NGSS 4-PS4-2. Develop a model to describe that light reflecting from objects and entering the eye.

✅ NGSS 4-LS1-1. Construct an argument that plants and animals have internal and external structures that function to support

survival, growth, behavior, and reproduction.

✅ NGSS 4-LS1-2. Use a model to describe that animals receive different types of information through their senses, process the

information in their brain and respond to the information in different ways.

✅ Also addresses Utah SEEd 4.3.2

Develop a model to describe how visible light waves reflected from objects enter the eye causing objects to be seen.
