Vocabulary for Specific Sciences

No discussion of scientific vocabulary would be complete without the names and subjects of the main scientific disciplines. Briefly,

  • Chemistry studies the building blocks of matter and chemical reactions.
  • Physics studies the basic laws of matter and energy.
  • Astronomy studies the universe, stars, and planets.
  • Geology studies the earth and its composition.
  • Meteorology studies the weather and climate.
  • Biology studies life and the way living organisms function and interact. 

Some of the biological sciences include genetics, botany (the study of plants), zoology (the study of animals), anatomy and physiology (the structures of our bodies and the way they function), and ecology (the way living things interact with each other and their environment).

Words for Health, illness, and Types of Germs has health-related science vocabulary and practice. 

You can learn much more about physics, chemistry, biology, and the other sciences, as well as the specialized vocabulary you need to understand each of them, in the Science section of Thought Company. It's fascinating!
