What is a lens?
A lens is a specially shaped piece of glass. When light hits hit the light is refracted. This means that the light changes direction slightly. When you view objects through a lens they may appear bigger, smaller, closer, further away or upside down.
This is a convex lens and it makes my eye look larger.
This is a concave lens and it makes my face look smaller.
If you use 2 magnifying glasses at once the image will be even bigger.
A simple telescope can be made out of 2 lenses. We tried using to convex lenses and the image appeared upside down. When we used a concave and convex lenses the image was the right way up.

Wow! I’m also learning about this right now in school! This really helped me understand concave and convex lenses! Thank you so much! I think I’m ready for my test on Tuesday! Wow!
