Describes the contributions of scientists over hundreds of years leading to our current understanding of the eye and vision.

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 design a morning routine for a 60 year old female senior with vision disorder. For this biology lesson, 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...

Did you know the ancient Greeks first identified the three states of matter? Read about how the molecules differ in solids, liquids, gases, and plasma. View photographs and watch how the molecules move in each state. If you're really...

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.
