You will have to prepare an oral presentation about how the human eye works and about the practise you did in the Natural Science class. In order to do it well you will also need some other suport such as a power point, a slide, a poster or some photographs. All the members of the group will have to participate in the presentation. In order to organise it properly you will begin by a introduction and finish with a conclusion.
You will have to hand in the script of the presentation to your English teacher.
