Questions and Answers

What best describes the function of empirical evidence in scientific research?

It relies solely on theoretical models without practical application.

It is primarily based on personal testimonials.

It serves as the foundation for scientific knowledge obtained through observation and experimentation. (correct)

It is data derived from speculation and assumptions.

Which aspect of scientific practices ensures the validity of research findings?

Displaying results without independent verification.

Relying on anecdotal experiences.

The peer review process where researchers critically evaluate each other's work. (correct)

Using only a single method for experimentation.

In the context of scientific investigations, what role do controlled variables play?

They are the variables that are left uncontrolled to observe their effects.

They are kept constant to isolate the effect of the independent variable. (correct)

They are the factors that change independently during an experiment.

They are the results that are measured at the end of the experiment.

Study Notes

Introduction to Science

Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.
It relies on empirical evidence, which is obtained through observation and experimentation.
Science aims to understand the natural world through a process of inquiry.

Branches of Science

Natural sciences study the natural world and encompass various disciplines, including:
- Physics: Studies matter, energy, and their interactions.
- Chemistry: Studies the composition, structure, properties, and reactions of matter.
- Biology: Studies living organisms and their interactions.
- Earth science: Studies the Earth's structure, processes, and history.
- Astronomy: Studies celestial objects and phenomena.
Social sciences investigate human behavior and societies, such as:
- Psychology: Studies mental processes and behavior.
- Sociology: Studies human social behavior and societies.
- Economics: Studies production, distribution, and consumption of goods and services.
- Political science: Studies political systems and behavior.
- Anthropology: Studies human societies and cultures.
Formal sciences utilize abstract structures and mathematical systems, including:
- Mathematics: Studies quantity, structure, space, and change.
- Logic: Studies the principles of valid reasoning.
- Computer science: Studies information and computation.

Scientific Method

The scientific method is a systematic approach to understanding the natural world.
It involves several key steps:
- Observation: Noticing a phenomenon or pattern.
- Questioning: Formulating a question about the observed phenomenon.
- Hypothesizing: Proposing a possible explanation or prediction (the hypothesis) for the phenomenon.
- Experimenting: Designing and conducting experiments to test the hypothesis.
- Analyzing results: Evaluating the data from the experiment.
- Interpreting results: Drawing conclusions from the analysis.
- Revising or accepting: Adjusting the hypothesis or developing new ones based on the results.

Key Concepts in Science

Theory: A well-substantiated explanation of some aspect of the natural world, supported by a large body of evidence.
Law: A concise statement or mathematical equation that summarizes a vast body of observations about a specific phenomenon or relationship.
Variables: Factors that can be changed or measured in an experiment.
- Independent variable: The factor that is manipulated by the researcher.
- Dependent variable: The factor that is measured to see how it is affected by the independent variable.
- Controlled variables: The factors that are kept constant throughout the experiment.
Empirical evidence: Data obtained through observation and experimentation, it forms the foundation of scientific knowledge.
Reproducibility: Experiments should be repeatable by other scientists with similar results obtained, lending credence to findings.
Peer review: A process where scientists critically evaluate each other's work before publication to ensure quality and validity. This process helps maintain high standards in scientific research & publication.
Models: Simplified representations of complex phenomena or structures that help us visualize and understand them.
Models in science can be physical, mathematical, or conceptual.

Importance of Science

Science provides a framework for understanding the natural world and its processes.
It enables technological advancements and innovations that improve human life.
It helps us address global challenges such as climate change, disease, and food security.
It fosters critical thinking, problem-solving skills, and a deeper understanding of the world around us.
Scientific inquiry promotes questioning, evaluation, and constant refinement based on evidence.
