How does a magnifying glass work?
Answer 1:

A magnifying glass works by bending the light into your eyes to make small areas appear bigger. A magnifying glass is a "convex" lens, meaning it is rounded like a glass of water ( click here to see ).

Light, when it is in the lens, is bent to "spread out" the image and make it bigger. Seeing makes it easier to explain: see here

Imagine you have the convex lens on the left, and you are looking in from the left. The magnifying glass will redirect your vision toward that "focus" on the right by bending the light coming into it. If you want to observe this in similar situation, look at your hand through a clear glass of water. Concave lenses are used in eyeglasses. If you or your parents have glasses, hold them away from your face and look at them as if it were a magnifying glass. Everything will appear smaller rather than larger.
