A plumber's nightmare

Made by Sander, 12 years old

You need:

1. white drawing paper A4 size
2. colour pencils
3. pencil
4. fine black marker
5. coloured paper for background

Talk about the work of the plumber. View the pipes under a sink: how are the pipes connected, how are curves made? Talk about the horrible things a plumber may encounter: leaking pipes, filthy creatures, smelly sludge. Imagine with the class on a sewer pipe system which is inhabited by creepy creatures.

How do you draw a pipe? How can you show that a pipe is round? Where is the light part and where are the shadows? Show this on the blackboard. Children draw 'A plumber's nightmare' according to their own imagination. Leave the pipes white, make shadows with pencil lines. Outline evertything with a fine black marker. These drawing can also be done by a group. This requires the students to make agreements on connecting the pipes at each drawing.
