Скачать или смотреть Difference Between Hypothesis, Theory, & Fact | Stages of Science

The terms hypothesis, theory, and fact are distinct concepts in science and understanding their differences is essential. Here's a breakdown:

1. Hypothesis
A hypothesis is a testable and falsifiable idea or prediction about how something works or why something happens. It is often the starting point in scientific inquiry.

Key Features:
Based on observations or prior knowledge.
Tentative and needs to be tested.
Example: "If plants receive more sunlight, then they will grow faster."
2. Theory
A theory is a well-substantiated explanation of some aspect of the natural world that has been repeatedly tested and confirmed through experimentation and observation. It integrates facts, laws, and tested hypotheses into a coherent framework.

Key Features:
Broad in scope and supported by extensive evidence.
Subject to revision if new evidence arises but is usually very robust.
Example: The Theory of Evolution by Natural Selection explains the diversity of life on Earth.
3. Fact
A fact is an observation or piece of information that is confirmed to be true and can be directly verified. Facts are the building blocks of science and are used to support hypotheses and theories.

Key Features:
Objective and indisputable under current understanding.
Example: "Water boils at 100°C at sea level."
