One of the functions of visual language is describing things. Many scientists use pictures to describe and explain nature, especially animals, plants and parts of the human body.
Drawing animals and plants as a science exercise is called "Naturalist drawing". Those pictures are very realistic, because the author wants to show all the details of the living being he has been drawing. The aim of the artist is that anyone who looks at the picture should be able to recognize it if they see it in real nature. The picture is part of the author's scientific work.
We are going to practise Naturalist Drawing. The first activity will be drawing a leaf of a tree we can find in our school's playground. Please, pay attention to all the details and try to draw and colour it as it is exactly.
