“In Darwin’s Steps” is an environmental Science project, which focuses on the classification, adaptation and evolution of living creatures. Making the most out of the CLIL methodology, the project aimed at helping students understand the above issues in a funny, interactive, easy-to-learn way and making them producers of their own learning. As a result, the students developed material in English on the afore-mentioned areas with the help of digital tools and guidance from teachers and experts involved in the project.
