Questions and Answers

What is the basic approach of science in determining what is true?

The basic approach of science is to propose a hypothesis and test it through experiments to see if it holds up against evidence.

How does inductive reasoning differ from deductive reasoning in scientific inquiry?

Inductive reasoning involves forming hypotheses based on observations and is speculative, while deductive reasoning involves deriving conclusions that must logically follow from true premises.

What is the role of evidence in the scientific method?

Evidence serves as the final arbiter of scientific truth, determining whether a hypothesis is supported or contradicted by observations.

In what way does science advance according to the content provided?

Science advances by disproof rather than proof, becoming more accurate by eliminating wrong ideas. Signup and view all the answers

Study Notes

Understanding Science

Science is a method for determining truth through empirical evidence.
It relies on external testing of ideas to confirm or refute assertions.
Evidence serves as the ultimate judge in scientific discourse.

The Role of Biology

Biology focuses on the empirical study of life forms and living processes.
It involves testing hypotheses related to living organisms against evidence.

Scientific Methodology

Scientists propose a hypothesis to explain phenomena and test it through experiments.
Inductive reasoning is employed to formulate hypotheses, leading to probable conclusions based on evidence.
Conclusions from inductive reasoning are not guaranteed, inviting a degree of speculation.

Inductive vs. Deductive Reasoning

Inductive reasoning allows for creating multiple plausible hypotheses but cannot confirm their correctness.
Deductive reasoning provides absolute conclusions based on true premises, allowing for definitive predictions.
The empirical process helps science distinguish valid hypotheses from incorrect notions over time.

Progression of Scientific Knowledge

Science advances through the disproof of incorrect ideas rather than outright proof.
It comprises both the process of investigation and the accumulated knowledge.
Claims that cannot be tested scientifically fall outside the realm of science.

The Dynamics of Scientific Theories

Theories are broad explanations that connect various observations across disciplines.
A theory must generate testable predictions consistent with evidence to be considered valid.
Major scientific theories include:
- Cosmology: Big Bang Theory
- Physics: Atomic Theory, Thermodynamic Theory, Quantum Theory, Theory of Relativity, Theory of Gravity
- Geology: Theory of Plate Tectonics
- Biology: Cell Theory, Germ Theory, Endosymbiotic Theory, Theory of Evolution

Definition of Life

Life is defined as a self-perpetuating biochemical system capable of growth, response to stimuli, and reproduction.
Organisms, which are complete living entities, range from single cells to complex multicellular systems with trillions of cells.
The cell is recognized as the smallest unit fulfilling the criteria for life.
