Questions and Answers

Explain the crucial role of controls in scientific experiments and provide an example of a control used in a study about plant growth.

Controls provide a baseline for comparison, ensuring observed effects are due to the variable being tested. A control group for plant growth might receive water but no fertilizer.

Differentiate between a scientific theory and a scientific law using examples from physics or chemistry.

A scientific law describes what happens (e.g., the law of conservation of mass), while a scientific theory explains why it happens (e.g., the atomic theory explains why matter behaves as it does).

Describe how the use of SI units promotes consistency and accuracy in scientific measurements, and provide two examples of base SI units.

SI units provide a standardized system for measurements, reducing ambiguity and facilitating data comparison. Examples include the meter (m) for length and the kilogram (kg) for mass.

Explain why scientific knowledge is considered tentative and subject to change, even for well-established theories.

<p>Scientific knowledge is based on available evidence and can evolve as new evidence or improved methods challenge existing understanding, promoting accuracy.</p> Signup and view all the answers

Describe the limitations of science in addressing questions related to ethics, values, or subjective experiences.

<p>Science primarily deals with observable, measurable phenomena and cannot provide answers to questions of ethics, values, or subjective experiences as those rely on personal beliefs.</p> Signup and view all the answers

Study Notes

  • Science represents a systematic and organized method for deciphering the natural world.
  • It depends on observation, experimentation, and rigorous analysis to elucidate various phenomena.
  • Scientific knowledge is rooted in empirical evidence and logical reasoning.
  • Science is an ever-changing collection of knowledge.

Understanding Matter

  • Matter is anything with mass that occupies space in the Universe.
  • Matter can exist as a solid, liquid, gas, or plasma.
  • A substance's composition and structure dictates its properties.
  • Matter is able to undergo both physical and chemical changes.

Elements of Science

  • Science includes many disciplines focused on specific aspects of the natural world.
  • Disciplines include physics, chemistry, biology, geology, and astronomy.
  • Physics studies the universe's fundamental laws and principles.
  • Physics explores motion, energy, forces, and matter structure.
  • Chemistry is the study of matter, its properties, and how it changes.
  • Chemistry is concerned with the structure, properties, composition, and reactions of substances.
  • Biology studies living things, including structure, function, growth, evolution, and interactions.
  • Biology includes botany, zoology, microbiology, and ecology.
  • Geology studies Earth, its structure, composition, processes, and history.
  • Geology scrutinizes rocks, minerals, landforms, and forces that shape the planet.
  • Astronomy studies stars, planets, galaxies, and the universe as a whole.
  • Astronomy explores the celestial objects' origins, evolution, properties, and interactions.

Scientific Method

  • The scientific method is a systematic approach to scientific investigations.
  • Key steps include observation, hypothesis formation, experimentation, analysis, and conclusion.
  • Observation involves gathering information on a phenomenon using senses or instruments.
  • Hypothesis formation involves creating a testable explanation for an observed phenomenon.
  • Experimentation involves designing and performing controlled tests to acquire data.
  • Analysis involves examining experimental data to identify patterns and relationships.
  • Conclusion involves making inferences based on data analysis to determine if the hypothesis is supported or refuted.

Scientific Theories and Laws

  • Scientific theories are well-supported explanations of aspects of the natural world.
  • Theories are based on extensive evidence that has been repeatedly tested and confirmed.
  • Scientific laws are descriptive statements or equations that consistently describe phenomena under certain conditions.
  • Theories explain "why" something happens, while laws describe "what" happens.
  • Scientific theories and laws are subject to change as new evidence arises.

Measurement and Units

  • Measurement assigns numerical values to physical quantities.
  • It is essential for quantifying observations and performing experiments.
  • Units are standard measures used to express quantities.
  • The International System of Units (SI) is the primary system in science.
  • SI units include meters (m) for length, kilograms (kg) for mass, seconds (s) for time, and kelvins (K) for temperature.
