What is measurement in scientific experiments?

Back

Measurement is the process of obtaining the magnitude of a quantity, often using tools like rulers, scales, or thermometers.

Front

What is the importance of control variables?

Back

Control variables are factors that are kept constant during an experiment to ensure that any changes in the dependent variable are due to the independent variable.

Front

What is data collection?

Back

Data collection is the systematic gathering of information during an experiment, which can be qualitative or quantitative.
