The curdling scream

School Story Curriculum

Concept: How we see?

Once a fish was upset with the appearance of a shark. The fish saw the shark, and the shark saw the fish. The fish moved to an area of the underwater without moonlight and the shark could not see the fish anymore. The shark moved to deeper water and the fish lived on. The fish knew how the eye of the shark made images of the fish and how it saw so it used this knowledge to save itself.

It was able to hear a curdling scream. Another fish swimming under the moonlight had been caught by the shark. But it was a fact that he knew that eye of the shark allowed the light to enter, then the lens focussed the light, and the retina allowed the images of the visible world to form through the light. “So, if you want to escape sharks be in dark waters,” thought the fish.
