Spanish Vocabulary Science

Spanish science vocabulary is an essential part of academic language, covering various disciplines such as biology, chemistry, physics, and earth sciences. Having a grasp of science terms allows learners to engage in more advanced discussions, whether in a classroom, a research environment, or everyday conversations about scientific topics. Basic words like ciencia (science), experimento (experiment), teoría (theory), and investigación (research) are frequently used to describe general scientific processes.

In the field of biology, specific terms help explain the study of life and living organisms. Words like célula (cell), organismo (organism), ecosistema (ecosystem), and genética (genetics) are commonly used. Biology terms also include descriptions of human anatomy, such as corazón (heart), cerebro (brain), and pulmones (lungs). These terms are fundamental when discussing human health, environmental science, and the natural world.

Chemistry, which involves the study of matter and its properties, introduces another set of critical Spanish vocabulary. Terms like átomo (atom), molécula (molecule), elemento (element), and reacción (reaction) are commonly found in chemistry discussions. Understanding these terms is important for anyone learning about the composition and behavior of different substances, as well as how chemical reactions influence both industrial processes and everyday life.
