Frequently Asked Questions
What is the first step of the scientific method?
The first step is making an observation about something happening in the environment or asking a question about a natural phenomenon.
Why is a control variable important in an experiment?
A control variable is kept constant so that it does not affect the outcome, ensuring that the experiment only tests the effect of the independent variable.
Can a hypothesis be proven wrong during an experiment?
Yes, if the experimental results do not support the hypothesis, the hypothesis is either rejected or modified for further testing.
