Colours: human Vision and surroundings

We propose interdisciplinary teaching-learning sequences focusing on colours. How do we perceive colours? How do animals perceive it? How do some animals make unusual coloured liveries? The proposal was initially tested with high school students in a summer school, then it was discussed in a summer school for science teachers in order to enhance the interdisciplinary aspects. Finally, it was proposed and discussed in a training event for in-service science teachers. Involvement and motivation in the learning process were the main reactions expected and the forecasts were fully achieved.
