A small card with a dot and an X is held at arm's length and used to show youngsters where their blind spot is. This illuminating little activity is a compact addition to your lesson on the structure of the eye as it explains the part of...

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.

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,...

In this light and the eye worksheet, learners 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...

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,...

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 determine their eye's blind spot. In this biology lesson, students explain what causes this visual deficiency. They give real life applications of this concept.

Eleventh graders explain why colour blindness is more common in men than women.

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...

Students investigate the poisonous frogs of Manu, Peru. They watch and discuss a video, conduct Internet research on poison frogs, accurately color downloaded template models of the frogs of Manu, and create a poster using the colored...

Learners are introduced to raptors and their role in the environment. They identify three characteristics of raptors and list several types of raptors found in nature. They discuss their positive and negative experiences with raptors and...

Students participate in this program that heightens their awareness and curiosity of nature as well as their sense of adventure and exploring new surroundings. They identify and choose an object from nature after exploring it with other...

Students make a graph that shows how the number of sunspots has changed over the past 30 years and discover how there is a pattern in sunspot number. They find a disruption in this pattern due to the Little Ice Age.

The blind spot in human vision is described and illustrated.

Did you know that there is a part of your eye that does not give you any visual information? In this activity learn about this part of the retina called the "blind spot".

Take this little test about the blind spot, then click on the red "explanation" button at the bottom of the page to find out what you just experienced.

Discover the blind spot in the human eye with a simple experiment, then alter the experiment to discover the size and shape of your blind spot.

In this service-learning engineering project, students follow the steps of the engineering design process to design a hearing testing device. More specifically, they design a prototype machine that can be used to test the peripheral...

Part of a larger sight on the eyeball and its function, this section describes the process of sight and ranges in topics from the chemical reaction of light hitting the retina to blind spots and animals seeing color.

Try this experiment where you examine the blood vessel network of your retina and the eye's blind spot. Includes a safety precaution.
