What is the purpose of a hypothesis in scientific investigations?

Back

A hypothesis is a testable prediction about the relationship between the independent and dependent variables.

Front

What is the significance of conducting repeated trials in an experiment?

Back

Conducting repeated trials helps to ensure the reliability and accuracy of the results.

Front

What is the role of observations in scientific investigations?

Back

Observations are used to gather data and evidence during an experiment, which can lead to conclusions.

What is a conclusion in the context of scientific investigations?

Back

A conclusion is a summary of the results of an experiment, indicating whether the hypothesis was supported or not.
