An art object is something that someone made to look special or interesting. It can be a painting, a sculpture, a drawing or anything else that an artist creates. The artist uses their creativity and imagination to make something that they think is beautiful or meaningful. Think of it like making a really cool toy that you can show off to your friends. It might be simple or complicated, but the point is that it's unique and special. So when you go to a museum or an art gallery, you can see a bunch of different art objects made by different artists. And you can appreciate them for their beauty and creativity.
