Science is a vast ocean, so we divide it into different branches to study it better. For Grade 6, we focus on three main pillars:
Biology: The study of living things (plants, animals, and humans).
Physics: The study of matter, energy, light, and sound. It explains how things move!
Chemistry: The study of substances and how they react with each other (like how milk turns into curd).

Ask a Question: "Will this plant grow better in sunlight?"
Form a Hypothesis: Make an educated guess.
Test/Experiment: Put one plant in the sun and one in the dark.
Analyze Results: Measure the height of the plants.
Conclusion: Decide if your guess was right.
