Science
Hypothesis and experimentation
In Class 9 Science, within “Exploration: Entering the World of Secondary Science,” students learn how scientific questions can be turned into testable hypotheses. They examine the difference between an observation, an inference, and a prediction; identify variables and controls; plan fair experiments; and record evidence carefully. The topic develops skills in measuring, organizing data, interpreting results, recognizing sources of error, and drawing conclusions supported by evidence. Students also understand that experiments refine ideas rather than simply prove them.
