What is the scientific method?

Back

The scientific method is a systematic process used for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge. It typically involves making observations, forming a hypothesis, conducting experiments, and drawing conclusions.

What is a hypothesis?

Back

A hypothesis is a testable prediction about the relationship between two or more variables. It is often formulated as an 'if-then' statement.

What is an independent variable?

Back

The independent variable is the one variable in an experiment that is purposely changed or manipulated by the scientist to observe its effect.

What is a dependent variable?

Back

The dependent variable is the variable that is measured or observed in an experiment. It is affected by changes in the independent variable.

What is a control group?

Back

A control group is a group in an experiment that does not receive the treatment or intervention and is used as a benchmark to measure how the other tested subjects do.

Front

What is the purpose of conducting experiments?

Back

The purpose of conducting experiments is to test hypotheses, gather data, and draw conclusions about the relationships between variables.

Front

What is an observation in the scientific method?

Back

An observation is the act of noting and recording something with instruments or through the senses. It is often the first step in the scientific method.

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).

What is the importance of repetition in experiments?

Back

Repetition in experiments is important to ensure that results are reliable and can be reproduced. It helps to confirm findings and reduce the impact of anomalies.

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 stood up to repeated testing.
