Questions and Answers

What distinguishes a scientific law from a scientific theory?

A scientific law explains why phenomena occur, while a scientific theory describes what happens.

A scientific law can be changed by new evidence, while a scientific theory remains constant.

A scientific law is established through experimental results, whereas a scientific theory is based solely on observation.

A scientific law universally describes a fundamental principle, while a scientific theory provides explanations consistent with evidence. (correct)

Why is it important for scientists to acknowledge the limitations and uncertainties of their findings?

To enhance their credibility and encourage public trust in scientific findings. (correct)

To avoid legal repercussions related to their research.

To prevent others from conducting similar experiments.

To ensure that their findings will always be accepted by the scientific community.

Which statement best describes the relationship between scientific measurements and standard units?

Accurate scientific measurements rely on the use of standardized units to ensure consistency and comparability. (correct)

Standardized units are used exclusively for theoretical calculations, not for practical measurements.

Measurements in science are often made in arbitrary units that vary by region and discipline.

Standard units are optional in scientific measurements, depending on the preference of the researcher.

How should scientists respond to established knowledge when faced with new evidence?

They should critically evaluate the new evidence and be willing to challenge established knowledge if warranted. Signup and view all the answers

Study Notes

The Scientific Method

Science is a systematic approach to understanding the natural world through observation, experimentation, and analysis.
The scientific method is a framework for conducting scientific research.
It involves formulating a testable hypothesis, designing experiments to collect data, and analyzing the results to either support or refute the hypothesis.
Key steps in the scientific method include: observation, hypothesis formation, prediction, experimentation, data analysis, conclusion, and further investigation/refinement of the theory/model.
Observations can be qualitative (descriptive) or quantitative (numerical).
A hypothesis is a tentative explanation for an observation.
A prediction is a specific statement about the expected outcome of an experiment if the hypothesis is correct.
Experiments are designed to test predictions.
Data collection involves carefully measuring and recording observations.
Analysis of the data involves comparing the results to the prediction and drawing conclusions.
Results may support, reject, or modify the hypothesis.
Further experimentation may be necessary to refine the understanding.
Scientific explanations are based on evidence and are subject to revision as new evidence emerges.
The scientific method is iterative and self-correcting.

Branches of Science

Science is broadly categorized into physical sciences (physics, chemistry, astronomy) and life sciences (biology, zoology, botany).
Interdisciplinary fields such as environmental science and biophysics combine knowledge from multiple branches.
Physics studies fundamental laws of nature governing matter and energy.
Chemistry examines the composition, properties, and reactions of matter.
Astronomy studies celestial objects and their movements.
Biology studies living organisms and their interactions.
Zoology studies animals.
Botany studies plants.

Scientific Process and Reasoning

The scientific method is not a rigid set of steps but a flexible framework.
Critically evaluating scientific claims is crucial; looking for biases, limitations, and potential errors is vital.
Experimental design is crucial, ensuring validity and reliability.
Reproducibility is essential; other researchers should be able to perform the same experiments under the same conditions and obtain similar results.
Peer review helps to ensure quality control by evaluating other scientists' work.
Scientific conclusions are based on evidence, and scientists must be honest about the limitations and uncertainties in their findings.
Scientists should always be willing to challenge established knowledge in light of new evidence.

Scientific Theories and Laws

A scientific law describes a fundamental principle of nature that is consistently observed to be true.
A scientific theory is a well-substantiated explanation of some aspect of the natural world that is consistent with accumulated evidence.
Theories are supported by extensive evidence from various sources.
Laws and theories explain different aspects of nature.

Scientific Measurement and Units

Accurate and precise measurement is essential in science.
Measurements use standardized units (e.g., the International System of Units (SI)).
Quantities are carefully measured and recorded to avoid errors.
