We aim to develop in students a curious, flexible, and analytical mindset and encourage them to investigate and develop skills of searching and processing information. Additionally, science requires developing inference, communication, and collaboration abilities, enabling them to cultivate habits of reflection and collaborative work. Through an interdisciplinary approach, students study Mathematics, Physics, Chemistry, Biology, and Environmental Science in both Spanish and English, enabling a deeper understanding of the world and an appreciation of mathematical and scientific knowledge as a cultural asset that impacts society.
