4th Grade Science - Unit 2 Ch 3 Vision and Light

A structure that responds to information coming in from the environment

receptor

The pupil lets in light and information and bends it into images it can see

What does the pupil do?

They respond to information from the light and send that information to the brain

What do the light receptors do?

It carries the information from the light receptors to the brain

What does the optic nerve do?

The brain makes a picture with the information

What does the brain do?

To change information from one form to another

Process:

Light receptors to form an image

The brain does a job of‘‘ connecting the dots’’ or processing the information from the blank to form a blank that we can see

More questions and new ideas for what they want to investigate

After learning something new scientists often have blank questions and blank ideas for what they want to investigate

You get information about the environment by seeing or hearing it. Your brain processing it and comparing it to memories. You then use the information to decide how to react.

You can get blank about the environment by blank or blank it your blank it, and comparing it to blank you then use the information to decide how to blank

The eye and the brain have different structures

The blank in the blank have different blank that work together to allow an animal to see something and know what it is looking at

When light gets to a geckos eyes, it enters the eyes and gets the light receptors in the back of the eye. Next, the light receptors respond to the light and send information from the light to the gecko‘s brain. Finally, the brain processes this information and formed an image of the prey. The burning compares this to its memories. The gecko realizes it’s looking at its prey. It decides to eat it.

write a scientific explanation that answers the questions below how to take a gecko structures allow it to see. Pray how I took a gecko nose, how to react when it sees this pray
