Science is reliable because it is open to being corrected by new evidence. No theory is ever final; ideas are constantly tested, revised or discarded based on critical examination and updated empirical observations.

A law describes a regular pattern in nature. A theory provides an explanation for why those patterns occur based on evidence. Principles are broad ideas that help make sense of a given situation.
Estimation is vital because it builds intuition, helps detect potential errors in calculations and confirms if a result is reasonable. It allows for quick evaluation, which is often sufficient in early scientific reasoning stages.
A situation defines the problem. Quantities are the measurable factors within it. Estimation simplifies these into useful approximations. Together, they form a strategy by managing complexity, allowing quick analysis before attempting precise, full calculations.
Yes/no questions limit inquiry to binary answers. Evidence-based questions, however, focus on patterns and “how” or “why,” uncovering the deeper mechanisms of nature. This depth fosters critical thinking and leads to authentic scientific understanding.
