Learning through a Project Based Activity. Students will perform research on recyclable and non-recyclable plastics and the amount of daily plastic waste in our school. In order to reuse the plastic water bottles, they will explore ways they can create ecological straws with filters that can be used to produce clean water from the sea or rivers. Various types of filters will be tested. With their final product the students will be able to create their own small scale business (start-up), entering an eco-friendly entrepreneurship world and discovering the basic principles of marketing. A complete STEAME+ Learning Approach that involves Mathematics, Physics, Chemistry, Biology, Technology, Engineering, Computer Science (STEM), Arts (A), Entrepreneurship (E), as well as Language and Culture (+).
