Okay kiddo, let me explain what still life means. You know how sometimes you see a picture or a painting of a bowl of fruit or some flowers or maybe even some toys on a table? That's called still life.
Still life is when an artist takes objects, arranges them in a certain way, and then draws or paints them. They can use all sorts of things for still life, like fruits, vegetables, flowers, books, toys, or even just ordinary objects like a pencil or a glass of water.
The cool thing about still life is that the artist can choose how to arrange the objects and what colors to use to make it look pretty. It's almost like setting up your own little scene in real life and then drawing it to make a picture.
Sometimes artists will use still life to practice their skills, like making things look 3D or how to use shadows to create the illusion of depth. But other times, they just do it because it looks nice and they want to make a pretty picture.
So that's what still life is, buddy. A picture or painting of arranged objects that an artist made because they thought it looked pretty or wanted to practice their skills. Pretty cool right?
