Transferable/Scientific Skills Developed
To observe , to understand ,to acknowledge the physic laws that govern the phenomena and to reproduce them with simple experiments.

Description
• The general aims are to develop the observation skills and the ability to work in a team enhancing their attitude and those of the others and managing conflict. To contribute common learning to carry out group activities. To work in an independent and responsible way: to be able to fit in an active and conscious way in the social life and in this context to assert their rights and needs while recognising those of the others, the common opportunities, the limits, the rules, the responsibility.
• The linguistic aims are to teach students a correct scientific language . They will have to read or to watch and to understand a scientific article or video. They will have to use a correct language when they have to explain a scientific topic.
• The specific aims are to learn to verify the theory by the simple observation of daily life recognising the physic laws that govern the phenomena observed. To learn to apply the laws of physic to reproduce phenomena with simple experiments like the reproduction of the rainbow or other similar effects .
• The target group age is 16 /18
• The level of competence in English is B1/B2.
• The time required to use the resource with the students is about two hours: one hour to look at the on line lab and to reproduce the rainbow, helped by the teacher, with a prism or with a glass of water. Another hour, to reproduce the experiment that the students have found online as homework .
• After watching the on line lab, the teacher must help the students to work in groups to reproduce that phenomenon in class. Then he asks the teams to look for other on line similar resources for homework. Every group must look for a specific topic (refraction of the light in two medium or total refraction or scattering....) and they must reproduce these experiments in class.
• Normally the students do not have any problem to make these experiments, in fact they are very amused by the activity.

Comments
• Strength: The weaker students, working and interacting in group, can be helped by other students. The reproduction of a phenomenon is a good way to fix the phenomenon itself and the laws that govern it. To look for resources on line accustoms the students to choose the information in a critical way and to assess reliability and credibility. • Weakness: The teacher should be careful to select the students for each group in order to achieve the best results and enhance group working strategy • Scientific reliability: good. The first part is a short revision of the origin of the rainbow, but the second part, relating to the experiments, is very detailed and well done. • Pedagogical value: collaborative learning, self–directed learning, homework and group work are used in this lesson.
