How We See: The First Steps of Human Vision

Reading essays about deep-sea expeditions open this instructional activity on crustacean vision. Marine biology explorers study the compound eye and then complete a worksheet in response to all they have discovered. Although the...

Students investigate the vision adaptations in marine animals in their environments. In this life science lesson plan, students use polarized filters and make observations.  Students explain how the adaptation of polarized vision is an...

Can an organism with no eyes still see? As it turns out for the purple sea urchin, the answer is yes. In a short video, scientists explain why they believe that some sea urchins can use their spikes to visually sense the environment. 

Pupils put together their own stroboscopes so that they can observe how cyclically moving images appear to merge into a singular object. This, and several other activities published by the same source, illuminate the way the brain...

Students investigate ways in which new vision tests and technologies can be used to help detect and correct vision problems. They begin by reading the Times article, Software May Replace the Eye Chart on the Wall. They stage a medical...

Students design a morning routine for a 60 year old female senior with vision disorder. In this biology activity, students collaborate with their team to come up with possible solutions. They present at least two ideas of their design to...

A short interactive allows scholars to view a model of the anatomy of an eye that provides a description of how each part works and models how the parts function together. A short quiz on both the anatomy and the functions allows pupils...

Viewers use a small, dimmed flashlight to identify the blind spot for both the right and left eye. It is a simple activity to incorporate into your activities during a lesson on vision and the structure and function of the eyeball.

Divide your field of vision in two and see what happens when your two eyes behold two different scenes! This is a way to demonstrate to body-systems buffs how the two eyes usually blend pictures to create a three-dimensional view. This...

Take a look at an organized physics course. The 34-section electronic textbook covers material in AP® Physics 1 and 2. Teachers use the text to supplement lectures and have the class work through the labs. Each section contains multiple...
