The Magnifying Glass
Have you have ever used a magnifying glass
to look at stuff? A magnifying glass makes everything appear much bigger than
what it is. Joey likes to look at ants with a magnifying glass. A magnifying
glass is a lens that has a handle on it so you can hold it in your hand and
look through it and be able to see the fine tiny details on stuff. A magnifying
glass can make an object appear 2 to 3 times bigger. They have ones that can
make objects as big as 5 to 10 times bigger. Roger Bacon invented the
magnifying glass. The first time the magnifying glass was mentioned as being
used was in 1268.
Facts about the magnifying glass:
1. A magnifying glass is a convex lens that is made of glass
or plastic. Convex lenses are used in eyeglasses, telescopes, projectors, cameras,
and microscopes. The human eye even has a convex lens. A convex lens is usually
thinner at the edges and thicker in the center. Convex lenses are used to bring
distant light rays to a focus in your eyes. It helps make things appear bigger
and more focused.

sizes.

magnifying glass.

tiny insects. People use magnifying lenses to study stamps and coins.

skills by letting them use a magnifying glass to let them see things they
haven’t seen up close before like a tiny ant or other small insects.
