Unit 1 - Lesson 1 - scientific knowledge

What is a scientific theory?

Back

A scientific theory is a well-substantiated explanation of an aspect of the natural world that is based on a body of evidence and has been repeatedly tested and confirmed through observation and experimentation.

What is the difference between a scientific law and a scientific theory?

Back

A scientific law describes a consistent and universal relationship observed in nature, often expressed mathematically, while a scientific theory explains why and how that relationship occurs.

What is Boyle's Law?

Back

Boyle's Law states that at constant temperature, the pressure of a gas is inversely proportional to its volume. As pressure increases, volume decreases.

Front

What is the scientific method?

Back

The scientific method is a systematic approach to inquiry that involves making observations, forming a hypothesis, conducting experiments, analyzing data, and drawing conclusions.

Front

What is a hypothesis?

Back

A hypothesis is a testable prediction or educated guess about the relationship between two or more variables.

Front

What is the role of evidence in science?

Back

Evidence is crucial in science as it supports or refutes theories and hypotheses, guiding scientists in understanding natural phenomena.

Front

What is the importance of peer review in scientific research?

Back

Peer review is important as it ensures the validity, reliability, and quality of research before it is published, helping to maintain scientific integrity.

Front

What is a scientific law?

Back

A scientific law is a statement that describes an observable phenomenon or a relationship in nature that is consistently supported by evidence.

Front

What is the difference between qualitative and quantitative data?

Back

Qualitative data describes characteristics or qualities (e.g., color, texture), while quantitative data involves numerical measurements (e.g., height, weight).

Front

What is an experiment?

Back

An experiment is a controlled procedure carried out to test a hypothesis and observe the effects of changing one or more variables.
