Description
"Camera and Eyes" PPT
Part One: Activity One
Understand the basic structure
How does a camera work?
Cameras are made using the principle that convex lenses can gather light and capture images of objects.
How do eyes see objects?
Pupil---------Aperture
Lens---------Lens
Retina---------photosensitive film
The main part of the eye is the eyeball.
When light from objects enters the eye through the pupil and lens, images of these objects are formed on the retina. The optic nerve connected to the retina immediately reports these light signals to the brain, and we see these objects. The light from the object forms an inverted image on the retina, and the human brain can automatically adjust the inverted visual signal to form upright vision.

4. Combined with the structure of the camera, analyze the scientific principles of how the human eye can see objects.
The human eye is like a camera. The lens is the lens of a camera, the retina is the film, and the pupil is the aperture. After the light generated or reflected by surrounding objects enters the eye through the pupil and lens, it will form an inverted image of these objects on the retina. The optic nerve connected to the retina immediately reports these signals to the brain. The human brain can automatically adjust the inverted visual signal. Forming the feeling of uprightness, we see the object.
5. Do you know any animals with special eyes? Tell them to your classmates.
A flounder's eyes are on the same side of its body. When one of the chameleon's eyes turns to the left, the other eye can turn to the right. The compound eyes of insects are composed of many small eyes.
