Any three key features of science

Answer 1

The word science is derived from the Latin word 'Scientia' which means 'knowledge'. Science is the pursuit and application of knowledge and understanding of the natural and social world, following a systematic methodology based on evidence.

The key features of science are:

1. Empirical evidence - It refers to acquiring information through direct observation or experiments. Scientific knowledge is based on verifiable evidence.
2. Objectivity - This refers to the ability to observe and accept facts as they exist, setting aside all sources of expectations, values, prejudices, etc.
3. Scientific causality - Science aims to establish a cause effect relationship between the variables under consideration, i.e., the effect of the Independent Variable on the Dependent Variable.
4. Systematic exploration - Science adopts a sequential procedure for studying various phenomena. It includes scientific steps like formulating a hypothesis, collection of facts, scientific generalization, etc.
5. Replication - Scientific knowledge can be replicated under the same circumstances as the original experiment. This ensures the reliability of results in establishing a scientific theory.
6. Predictability - Science involves describing and explaining phenomena as well as making predictions accordingly.
