What is the scientific method?

Back

The scientific method is a systematic process for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.

Front

Why is it important to have a control in an experiment?

Back

Having a control allows scientists to isolate the effects of the independent variable and determine if the results are due to the treatment or other factors.

Front

What is data in the context of an experiment?

Back

Data refers to the information collected during an experiment, which can be quantitative (numerical) or qualitative (descriptive).
