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,...

To illuminate how afterimage occurs, create a star, square, or other geometric-shaped light for learners to look at for 30 seconds. Then, have them explain what they see as they shift their focus to a blank wall. A full explanation of...

What will viewers see when they watch this video about vision? They will observe RJ and Sam hanging out during a power outage with Rookie, the dog. The boys discuss the structure of the eye (pupil, iris, cornea, lens, retina, optic...

Take a peep into optics. Pupils watch a video about a large Polaroid camera before building pinhole viewers. The scholars then create different types of viewers and compare them to determine which provides the best image.

Can you eyes be fooled into seeing colors that aren't actually there? Budding scientists view a presentation that addresses this topic. They explore how their eyes interpret color through the retinas and messages sent to the brain. They...

Explore the difference between the two color wheels. The focus of the installment of a larger physics playlist is to explain the difference between mixing colored paints and colored lights. Viewers find that the components of their eyes...

Your eye cells come in different shapes and serve different functions; rod-shaped cells see shapes and cone-shaped cells see color. Video 18 in the series of 47 teaches all about vision. Scholars see (no pun intended!) how vision works....

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.

Take a look at the human eye through a different lens with this fun instructional video. Drawing the comparison between eyes and cameras, this resource helps young biologists better understand the anatomy and function of these...

We all know that the brain is responsible for our thoughts, actions, memories, and emotions, but it's far busier than we can possibly imagine. Watch this short video as it explores how life as we know it is made possible...

Whether it's healing a cut or mending a broken bone, the human body is capable of some pretty amazing repair work, but does it have the power to reverse the blindness caused by genetic diseases? Following along as this video investigates...

Vision is arguably the most important of the five senses, but exactly how did we come by this amazing ability?  Find out with this engaging video on the 500 million year evolution of the human eye.

Ever find yourself looking at a clear blue sky and notice something that seems to be floating across your eye? Well, you're not alone. Watch this short video to find out exactly what causes this and other common visual phenomenon.

What have our eyes and brains evolved to see? Discover the way our photo receptors and brains assemble visual information into the three-dimensional world we see around us.

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...

Learners explore the nature of light. They use on-line articles and a worksheet to explore the roles of the eye and brain in the perception of color. They draw and label a diagram illustrating the movement of light.

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...

In this light and the eye worksheet, students perform eight tests to show the blind spot in the human eye, to demonstrate Benham's disk, to show how polarized lenses work, to show how light scatters, to demonstrate fiber optic, rainbows,...

In this eye and light worksheet, students make models of the eye using black and white cardboard, a light source, and a bowl of water. They explain how each part of the model corresponds to a part of the eye. Students answer 4 discussion...

Students examine the eyeball and its parts.  In this sight lesson plan students divide into groups and complete a lab activity that includes creating a model.

Young scholars study the eye and how all the parts work together.  In this cataract instructional activity students view an interactive website on the eye. 

In this functions of the human eye instructional activity students label A-E the correct function of each part of the eye on the provided diagram.

In this senses worksheet, students use the terms listed on the eye to label the figure and describe how light entering the eye becomes an image seen. Then they name the three main sections of the ear and explain what the cochlea does.

Students explore different parts of the eye and functions of each part through a video and a dissection of a cow's eye. They discover different causes of blindness.
