This module is designed to explore the use of colour in the environment.

Colour is very important to us as animals. It may be of interest for the students to look at the natural world, and study the uses of colour amongst animals and plants. This will include topics such as camouflage and warning colours [black and yellow hazard lines on dangerous vehicles have been specifically chosen to mimic the wasp and bee]. What would be the best colour for fire engines [tenders]. Pollinating insects see into the ultraviolet, as do some birds of prey, and flowers can reveal very different patterns when viewed under UV light. Fluorescent minerals also are very striking when similarly viewed.

Colour vision does not occur in all animals. Most mammals have very poor colour vision, or none at all. This could be guessed by looking at mammalian coloration, which is largely a collection of browns, greys, whites and blacks. After all, a black and white zebra would seem to stand out against the brown African veldt. Birds, reptiles and insects however, are often brightly coloured, indicating that they can see at least some colour. Your students might want to explore the reasons behind this phenomenon. Is it due to the fact that early mammals were nocturnal, in order to avoid dinosaur predators. Indeed, this may stimulate discussion on the coloration of dinosaurs.

The choice of colour in the Space Station may be more than chance. It may reflect the following concepts:

Coordination: each module can be identified by having a different overall colour scheme, and each relevant part of a module can be identified within the module.

Psychology: it has been found that people in offices work better if the colours are cool and neutral- pale green apparently being particularly effective. Perhaps the scientists will find it easier to work in a restful workplace. Other colours are known to cheer people up, and make them more positive.

Whatever the reasons behind the choice of colour, the astronauts will soon customise their particular personal space within the Space Station. Choice of colour then becomes a personal statement.

This module suggests some lines of enquiry rather than prescriptive projects, and it is hoped that the students will be able to improve on these, and create their own.
