NATURALIST DRAWING

"Nature is painting for us, day after day, pictures of infinite beauty if only we have the eyes to see them"
John Ruskin

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.

APPLIED GEOMETRY: SCRAPBOOK POLYHEDRON. 2nd ESO

We have been practising Technical Drawing for some weeks. I know that this part of the subject is difficult, and many of you find it the most boring thing in the world!

As we have drawn lots of polygons, I've thougth it could be a good idea to build 3D polygons. In geometry, they are called polyhedra (polyhedron in singular).

Polyhedra are beautiful 3D geometrical figures that have fascinated philosophers, mathematicians and artists. There are hundreds of polyhedra paper models on this site. And more here.

Our activity will be building a scrapbook icosahedron.  You will find detailed instructions here.

Material required

• Coloured cardboard
• Geometric compass
• Pencil and rubber
