What type of graph is used to show parts of a whole?

Back

A pie graph is used to show parts of a whole, representing the proportional relationship of one set of values in percentages.

Front

What is the first step in the scientific method?

Back

The first step in the scientific method is to identify a question or problem that needs to be addressed.

Front

What is a hypothesis in the context of scientific research?

Back

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

Front

What is the purpose of a control group in an experiment?

Back

The control group serves as a baseline to compare the effects of the independent variable, ensuring that the results are due to the variable being tested.

Front

What is the significance of replicating experiments in scientific research?

Back

Replicating experiments is important to verify results and ensure that findings are reliable and not due to chance.

Front

What is the role of data analysis in the scientific method?

Back

Data analysis involves interpreting the data collected during an experiment to draw conclusions and determine whether the hypothesis is supported.

Front

What is a variable in the context of scientific experiments?

Back

A variable is any factor, trait, or condition that can exist in differing amounts or types and can affect the outcome of an experiment.
