Our bodies have some amazing capabilities, but there are some limitations. Explore the limitations of the human eye through the eighth lab activity in a series of 12 biology lessons. Individuals measure their own peripheral vision...

Life science learners discover the range of peripheral vision. They compare the angles at which they can detect motion, colors, and detailed shapes. 

At one point, all mammals carried only two color receptors, but now most humans carry three. An informative presentation and hands-on activity demonstrate how this evolved through genetics. By participating in the activity, pupils...

Students are introduced to the relationship between light and vision. In groups, they participate in experiments to discover how different wavelengths are divided in the visible spectrum. They record their answers and discuss their...

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...

Third graders experience optic illusions by creating flipbooks. For this optics lesson, 3rd graders view a demonstration of the workings of rods and cones using a camera. They are shown an optical illusion and work to create their own...

Humans can only see visible light, but some insects can see ultraviolet light. Through a simulation, pupils explore how we see colors using one bulb. It moves on to demonstrate how we see colors by mixing three different bulbs (red,...

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

Students determine their own eyesight and calculate what a good average eyesight value for the class would be. They examine how technology enhances eyesight and how engineers play an important role in the development of these technologies.

Here is a great science lesson. It extends the concept of vision into the area of optical illusions, perspective, and tessellation. This well-designed plan has tons of great activities, utilizes interesting video, and should lead to a...

Ahoy, matey! Peer through a special telescope to explore the persistence of vision. The telescope has only a thin strip with which to view the world, but as it scans the area, your eye and brain work together to create a complete...

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...

Your eyes each work independently, so how do we only see one image? The quick hands-on experiment encourages young scientists to test their blind spots on each eye individually. After learning where the blind spot is and why it exists,...

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...

Construct a three-dimensional optical illusion when your class is exploring vision and how the eye and brain work together. Three concave corners are mounted inside of a black box, but as a light is shined upon them, they appear to be...

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.

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...

Using a dimmed flashlight, life science learners can see the network of blood vessels that line the back of their eye. Darken the room and let them try this activity as part of your unit on the eyeball. Also consider some of the other...

Fuzzy edges cause an image to fade from view in an activity intended to demonstrate how vision works. 

Put a new twist on your collection of optical illusion activities. Affix the linked printable spiral to a drill, record player, or some other rotating tool. Have learners stare at the spinning disk for only 15 seconds and then look away....

From the iris and retina to glasses and contact lenses, learners will be excited to see what activities are in store for them as they learn about the complex organ of the human eye.

Students review some basic biology by talking about how the eye works. They cover the concepts behind laser surgery as a treatment for saving sight. They begin to recognize the overlap of disciplines (physics and biology) required for...

Learners gain a conceptual comprehension of the functioning of the Human Eye in relation to optics and optical vision correction. They explore optics with light sources and various lenses, relating these to visual acuity, accommodation,...

Learners explore how light affects vision. In this light instructional activity, students construct a shoe box model to represent an eye. Experiments are performed with various light sources. Learners draw conclusions about how the eye...
