Key Branches of Science: A Helpful Guide for SAT, ACT, and EST Test Takers


Grasping the major branches of science is essential knowledge for standardized test takers preparing for the SAT, ACT, and EST exams. This post explores 10 key scientific fields including astronomy, botany, ecology, genetics, and more. Understanding these core disciplines provides a strong science foundation that supports success on test day.

Key Branches of Science: A Helpful Guide for SAT, ACT, and EST Test Takers 

  1. Astronomy – The study of everything beyond the Earth's atmosphere, including stars, planets, asteroids, galaxies, and more. Understanding physics and motion is key.
  2. Botany – The scientific study of plant life. Botanists study plant biology, growth, structure, genetics, ecosystems, and uses.
  3. Cognitive Science/Neuroscience – The interdisciplinary study of the mind and its processes, including intelligence, creativity, perception, language, emotion, and more. Examines mental processes through neuroscience, psychology, linguistics, and philosophy. 
  4. Ecology – The branch of biology focused on studying interactions between organisms and their environment. Includes studying biodiversity, populations, nutrient cycling, and more in ecosystems.
  5. Entomology – The zoological study of insects. Entomologists examine insect anatomy, morphology, evolution, behavior, habitats, and roles in ecosystems.
  6. Genetics – The study of genes, heredity, and genetic variation in organisms. Examines how genes determine characteristics, are transmitted between generations, and can change through mutation. 
  7. Geology – The study of the Earth’s physical structure, composition, and history. Includes plate tectonics, rocks, natural resource extraction, natural hazards, and past climate.
  8. Ornithology – The branch of zoology devoted to the scientific study of birds. Looks at avian evolution, anatomy, ecology, behaviors, and conservation. 
  9. Paleontology – Focuses on studying prehistoric life through fossils. Paleontologists learn about extinct organisms, evolution, environments, and geologic time periods.
  10. Zoology – The broad study of members of the animal kingdom, including their physiology, evolution, habitats, ecology, taxonomy, and more.  


With an overview of these major science branches, you’ll approach science-related test questions with confidence. Refer back to this guide as you prepare and study to reinforce your knowledge.



Q: How does learning the branches of science help on standardized tests?
A: Tests often include questions covering major scientific fields. Knowledge of the core disciplines improves comprehension.

Q: Which science branches are tested most often?
A: Biology-related branches like genetics, botany, and zoology are common. Physics branches like astronomy also frequently appear.

Q: What other science topics help on these exams?
A: Scientific method, experimental design, data interpretation, and technology/tools used in science are also key areas.

Q: What tips help remember the branches of science?
A: Mnemonic devices, charts relating branches to topics, and repetition through practice questions/flashcards aid memorization.

Q: Where can I find more resources to study science for these tests?
A: Official test prep books, review books, practice questions, sample tests, flashcards, and the test maker's website.
