Physical Science
Physical Science
Physical science studies non-living systems and the fundamental laws of nature. It focuses on how matter and energy behave and interact. Fields within physical science include physics, which examines forces and motion, and chemistry, which studies the composition and reactions of substances. Physical science helps explain phenomena such as electricity, gravity, chemical reactions, and the structure of atoms
Life Science
Life Science
Life science focuses on living organisms and how they function, grow, and interact with their environments. It includes fields such as biology, genetics, microbiology, and ecology. Scientists in this area study cells, plants, animals, microorganisms, and the complex systems that support life on Earth. Life science research helps us understand health, ecosystems, evolution, and the biological processes that sustain life.
Earth and Environmental Science
Earth and Environmental Science
Earth and environmental science examines the planet we live on and the systems that shape it. This includes the study of rocks, oceans, weather, climate, and natural processes such as earthquakes and volcanic activity. Scientists in this field also investigate how human activity affects the environment and how natural systems can be protected and sustained.
Space Science
Space Science
Space science explores objects and phenomena beyond Earth, including planets, stars, galaxies, and the universe as a whole. It includes areas such as astronomy, astrophysics, and planetary science. Researchers use telescopes, satellites, and space missions to study how celestial bodies form, evolve, and interact. Space science helps us understand the origins and structure of the universe.
