Answer 1

Science (from the Latin scientia, meaning "knowledge") is the effort to discover, understand, or to understand better, how the physical world works, with observable physical evidence as the basis of that understanding. It is done through observation of existing phenomena, and/or through experimentation that tries to simulate phenomena under controlled conditions.

Answer 3

Here's a good simple definition. One could of course add pages of explanations and examples, as well as discussion of what science is not and what is not science.

Science (from the Latin "scientia", meaning knowledge) is the effort to discover, understand, or to understand better, how the physical world works, with observable physical evidence as the basis of that understanding. Science is done by observation of existing phenomena, and/or by experimentation to simulate or generate phenomena under controlled conditions. Science yields verifiable factual statements about things and events and progresses by expanding and deepening our understanding of them.
