Seeing Your Blind Spot

In this light and the eye activity, 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...

Fifth graders investigate simple circuits and identify when a circuit is considered opened or closed. In small groups, they experiment with wires, batteries, and light bulbs to identify how to light the bulb. Students also experiment...

Learners examine how batteries work, how they provide power to the simple circuit within the battery, and how the switch controls the flow of electrons; students then disassemble a flashlight, and draw a schematic of a flashlight's...

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...

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,...

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...

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...

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...

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.
