Evolution & Experiment

This activity is available all year around at the Lovén Centre Tjärnö and is appropriate for high school science classes or equivalent. It is composed of equal parts evolution and experiment, using the species rough periwinkle as example.

We visit western shores of Saltö and puts us into life as a rough periwinkle in two different habitats. Crawling, crouching and lying on stomach the pupils sample the two habitat's varieties of periwinkles. At the same time the pupils consider what threats can cause periwinkles to die. In the lab, in groups, the pupils perform different experiments in order to describe differences between the two varieties. This gives training and introduction to scientific methodology. The pupils present orally how they have performed their experiments, their results and speculate what the differences mean in nature. Finally we explain how these differences have evolved through evolution, and what they have seen and studied is an example of how new species can evolve.

Time is 3,5 hours, approximately 1,5 hours in the field and 2 hours in lab. Maximum group size is 20 persons.
