Bike pedals can be made up of a lot of different kinds of materials. Pedals can be made up of metal or plastic for example.

Pedals allow the rider to propel the bicycle forward by applying force with their feet in a circular motion.
The correct thread direction for installing bicycle pedals is to turn the right pedal clockwise and the left pedal counterclockwise.
Cheap bikes are made with cheap parts. Plastic pedals are cheap to make. Better pedals are made out of metal. (Worth noting: better bicycles don't come with pedals at all. This way the rider can get the pedal system that works for the rider.)
