Investigation can take place anywhere, even at the lunch patio at school (place where photo was taken), and Investigation can touch upon things as simple as a leaf. People investigate even the simplest things from the moment they are born, and this is a prominent part of human nature, as not many living things are able to process information gathered through investigation on a level as deep as us. Investigation is really a simple idea that people misunderstand, but people can learn to understand it through realizing that they investigate almost everything they see.
