Sensory Perception: Light & Sound
Students take apart and reconstruct human eye models to learn about how we perceive light.
Visible light can be split into its component wavelengths.

Grade Level: Grades 4 through 8

Description: Sense receptors have evolved to receive information in a variety of forms including light and sound waves.  Internal and external body parts capture and convey this information which is then processed and integrated by the brain.  Students will learn about the principals of light and sound and participate in the virtual dissection of a model of the human eye to gain an understanding of the anatomy of the eye and how it collects and processes information in the form of light.


Next Generation Science Standards: 

LS1.A: Structure and Function: Plants and animals have both internal and external structures that serve various functions in growth, survival, behavior, and reproduction. 

LS1.D: Information Processing: Animals have body parts that capture and convey different kinds of information needed for growth and survival. Animals respond to these inputs with behaviors that help them survive. 


PS4.A: Wave Properties: A simple wave has a repeating pattern with a specific wavelength, frequency, and amplitude.


PS4.B: Electromagnetic Radiation: Objects can be seen if light is available to illuminate them or if they give off their own light.

  • 4-PS4-2: Develop a model to describe that light reflecting from objects and entering the eye allows objects to be seen.
  • MS-PS4-2: Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
