STEM Education

STEM education is an innovative educational approach that integrates science, technology, engineering, and mathematics. Its goal is to prepare students for careers related to these fields and to successfully face the social and economic challenges of the 21st century.

STEM Students

STEM students may face various difficulties depending on their level and experience, but some are common: limited understanding of basic concepts, difficulty applying abstract ideas to the real world, lack of critical thinking, low motivation, and little practice.

STEM Teachers

Being a STEM teacher is a significant challenge, as it requires not only highly specialized technical knowledge but also strong pedagogical and communication skills to convey these complex concepts clearly, engagingly, and effectively.

To learn and experiment

In each thematic unit, we offer science kits and educational tools that connect theory with practice in a fun and effective way

Edme Mariotte independently described the relationship between gas pressure and volume, known as Boyle-Mariotte’s law, contributing to the quantitative study of fluids

“Nature never acts in vain”

Fritz Haber

1868

–

1934

Fritz Haber developed the Haber-Bosch process, enabling large-scale ammonia synthesis, revolutionizing fertilizer production and industrial chemistry

“Chemistry has the power to transform life on Earth”

Charles Lyell

Gottfried Wilhelm Leibniz was one of the founders of infinitesimal calculus, created modern mathematical notation, and contributed to mechanics and optics with groundbreaking theories

“Music is the hidden exercise of arithmetic of the soul, which does not know it is calculating.”

Léon Foucault

1819

–

1868

Léon Foucault demonstrated Earth’s rotation with his famous pendulum and measured the speed of light with great precision, revolutionizing experimental optics

“The pendulum does not lie: the Earth moves beneath our feet”

Luke Howard
