Science education at various educational levels is the cornerstone of building students' scientific understanding. In elementary school, science education focuses on developing curiosity and acquiring basic concepts through simple activities and experiments. In middle school, scientific understanding is deepened by studying the principles of physics, chemistry, and life sciences in an integrated manner. In high school, biology is taught in a more specialized manner, as students learn about cells, genetics, body systems, and biological diversity, preparing them for university studies. Teaching biology and basic medical subjects such as anatomy, physiology, pathology, and pharmacology is an important pillar in preparing students for medicine, pharmacy, and nursing. The focus is on applied science, with the depth of content varying according to each specialty, using modern methods such as active learning, simulation, and e-learning to enhance understanding and critical thinking.
