Frequently Asked Questions

What makes science different from simply memorising facts about the world?
Science involves actively observing, questioning, and testing ideas about the natural world through experiments, rather than just memorising facts, building a deeper understanding of why things happen.

Why is asking questions considered an important first step in scientific learning?
Asking questions drives curiosity and guides the process of investigation, since identifying what one wants to find out is what leads to meaningful observations and experiments.
