Light and Eyes Science Activity

Make science homework meaningful by learning science by doing!

This exciting experiment has students discovering that the pupil in their eyes noticeably changes size in the light versus in the dark. Students will understand the important concept that our eyes take in light in order to see. This experiment can be a first step to understand the physics of light as well as the biology of the eyeball. You can do the activity in class or ask students to complete it at home for homework.

Included are:

• teacher notes
• a reproducible lab sheet for your students
• post-experiment teacher notes which explain (with an illustration) what students will have observed, along with a kid-friendly explanation, real-world applications and an extension activity.

The instructions are simple and require no extra materials. The students are literally amazed at what they see and instantly understand what is happening when their eyes "adjust to the dark."

This is a hands-on lab that is incredibly easy for a teacher to implement. Parents enjoy seeing kids doing an actual experiment at home and watching the surprising results.

Your students will love doing this.

This experiment works very well for distance learning and remote learning since the few required materials are things that students already have in their homes.
