How can you tell they’ve got it: How the Eye Works?

If they’ve got it, you’ll see things like: Name the main parts: pupil (lets light in), lens (focuses light), retina (detects light), optic nerve (sends signals to brain); Describe the sequence: light enters → lens focuses → retina detects → nerve signals brain → brain interprets image; Explain that the pupil gets bigger in dim light and smaller in bright light to control how much light enters. Or just try it together: Can your child explain what happens inside their eye when they look at something — how light comes in through the pupil and the brain turns it into a picture?

How the Eye Works

Your child can explain how we see. Light comes in through the pupil. A lens focuses it at the back of the eye, which sends a signal to the brain to read.

In curriculum terms

Describe how the eye works: light enters through the pupil, the lens focuses it onto the retina at the back of the eye, and the retina sends signals along the optic nerve to the brain, which interprets the image
