Reflecting Light Experiment

Shiny Spoons

 Materials you will need:

• Smiley Face
• Shiny Spoon

Steps:

1.  Look at your reflection on the inside of the spoon.

The surface on the inside of a spoon bends in like a cave - it is concave.

Dentist use concave mirrors to examine your teeth.  These mirrors make your teeth look bigger so the dentist can examine them more easily.  Likewise, shaving mirrors are concave because they make the face look bigger.

2.  Now turn your spoon out and look at your reflection on the outside of the spoon.

The surface on the outside of a spoon bends out - it is convex.

The next time you are at a funfair take a look at yourself in the crazy mirrors.  They bend in all sorts of ways so that you look bigger, smaller, fatter, thinner and even wavy.
