Back

A systematic process used for scientific investigation, involving observation, hypothesis formulation, experimentation, data collection, and conclusion.

What is a hypothesis?

Back

A testable prediction about the relationship between variables, often stated in an 'if-then' format.

Front

What is an independent variable?

Back

The variable that is intentionally changed or manipulated in an experiment to observe its effect.

Front

What is a dependent variable?

Back

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

Front

What are constants in an experiment?

Back

Factors that remain unchanged throughout the experiment to ensure that the test results are valid.

Front

Why is it important to conduct multiple trials in an experiment?

Back

To ensure reliability and accuracy of results, as one trial may not provide enough data to draw a valid conclusion.

Front

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

Back

To serve as a baseline for comparison, allowing researchers to see the effect of the independent variable.

Front

How can data be represented for better understanding?

Back

Data can be displayed on graphs or charts to make it easier to interpret and analyze.

Front

What is the role of observation in the scientific method?

Back

Observation is the first step in the scientific method, where scientists gather information and identify problems or questions.

Front

What is an experiment?

Back

A procedure carried out to test a hypothesis by manipulating variables and observing the outcomes.
