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

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...

Students discover the true value of their senses. In this sight lesson, students discover the difficulty of life without sight by performing everyday activities without the help of their eyes. The students examine their results and the...

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...

High schoolers 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...

Plastic math? Have young learners count and name the number of plastic items in their centers. Kindergartners match sight word cards to the number of plastics in a given group, while learning that plastics come in all different shapes,...

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. In 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...

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.

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...

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.

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.

There's no way around it—learners must use trigonometry to model the line of sight around a race track! Using the starting line as the origin, pupils model the straight line distance to any car using a trigonometric expression. The...

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...

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...

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...

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,...

Let's practice cutting and pasting! Kindergarteners color four farm animals and then cut out the back half of the animals and paste them on the correct front half. Farm animal names are included to help improve sight word recognition...

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

If you are setting up a rotation lab where learners are investigating vision at different stations, this activity can be used to explore depth perception. Setting up a giant needle eye, students attempt to pass a pencil through it with...

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...

Students 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,...
