Product Description

Three labs to look at our vision and how our eyes work. None of these require any setup so they can be used in centers or stations. As kids' understanding of light and optics develops it's cool to help them correlate that understanding with how their eyes work.

The directions are written directly to the students so you don't have to introduce them. They're great additions to a study of light and optics. Each lab includes cards for Claim, Evidence, and Reasoning (CER) that can be used in a variety of ways. Each of the three labs is complete in itself and is an extension of the concepts first taught in the activity

Use this to learn and reinforce answers to questions such as:

  • How does your eye react to changing light?
  • What is your blind spot and how can you demonstrate it?
  • How does your eye focus on different objects?

Once students try this activity, they can capture their observations using the included Lab Notes or probing questions included in the instructions. 

Concepts Addressed

  • Light stimulates a reflex to contract muscles in the eye.
  • Our retinas have a blind spot where there are no light receptors.
  • Muscles in the eye can stretch and change its lens’ shape.

Answer Keys and Teacher Notes address most questions and issues that might arise in this study—you shouldn’t have to do any outside research unless you want to.

Materials Needed A friend, Timer, Mirror (optional), Assorted eyeglasses (for far- and nearsightedness)

Prep Needed Gather supplies.
