Welcome back! Now that we understand that science is a process of curiosity and logic, let’s look at how we organize all that knowledge. Because the world is so vast—from the tiny atoms to the massive galaxies—scientists divide science into different branches.

Think of it like a library: instead of putting all books in one pile, we have sections for History, Fiction, and Sports. In science, we do the same.

Part 2: Branches of Science

Science is primarily divided into three main branches, each focusing on a specific part of our universe.

1. Physical Sciences

This branch deals with non-living things. It helps us understand the laws of the universe and the materials around us.

• Physics: The study of matter, energy, light, sound, and forces (like why a ball falls down or how a magnet works).

• Chemistry: The study of substances—what they are made of, their properties, and how they react with each other (like how milk turns into curd).

2. Biological Sciences (Biology)

This is the study of living organisms. It explores how life works, from the smallest bacteria to the largest blue whale.

• Botany: The study of plants.

• Zoology: The study of animals.

• Human Biology: The study of the human body and how it functions.

3. Earth and Space Sciences

This branch looks at our planet and everything beyond it.

• Geology: The study of the Earth’s structure, rocks, and minerals.

• Meteorology: The study of the atmosphere and weather patterns.

• Astronomy: The study of celestial bodies like stars, planets, and black holes.
