Potential energy is stored energy in something. For example, when a roller coaster is very high up on the track, it has a lot of potential energy before it goes down the track and continues going.
Kinetic energy is energy in motion. When the roller coaster goes down the track, that potential energy gets turned into kinetic energy.

Dark colored moths survived better in the Industrial Revolution because their dark color helped them camouflage in soot. When the industrial revolution ended there wasn't as much soot, so the light colored moths now had a better chance of survival.
