Some old movie theaters use

projectors with concave lenses.

A light in the projector shines

through a picture. A concave lens

makes the light rays spread out

and form a larger picture on

a screen. Some flashlights use

concave lenses, too.

Lenses in Science

Microscopes are science tools that

make small objects look larger.

Some use many lenses to help us

see things we can’t see with our

own eyes. Many microscopes have

mirrors , too. Scientists can study

cells with microscopes!
