What is a variable in an experiment?

Back

A variable is any factor, trait, or condition that can exist in differing amounts or types. In experiments, variables are what researchers manipulate or measure.

How many variables should be changed in a well-designed experiment?

Back

Only one variable should be changed to ensure that the results are due to that specific change.

What is data in the context of scientific experiments?

Back

Data refers to the information collected during an experiment, which can be organized into charts and graphs for analysis.

Why is it important to repeat experiments?

Back

Repeating experiments is important to verify results and ensure that they are consistent and reliable.

What is a hypothesis?

Back

A hypothesis is an educated guess or prediction about the outcome of an experiment, based on prior knowledge and research.

Front

What is the purpose of the research step in the scientific method?

Back

The research step involves gathering background information and existing knowledge related to the experiment to inform the hypothesis.

Front

What is an observation in scientific research?

Back

An observation is the act of noting and recording something with instruments or through the senses, which is crucial for forming hypotheses.

Front

What is a conclusion in the scientific method?

Back

A conclusion is a summary of the results of an experiment, indicating whether the hypothesis was supported or refuted.

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).
