Frequently Asked Questions
What is the very first step in any scientific investigation?
The first step is making careful observations of the world around you and asking a question about what you observe.
Why is it important to change only one variable at a time in an experiment?
Changing only one variable (the independent variable) ensures that the results are caused only by that specific change, making the experiment fair and accurate.
What should a scientist do if their experiment disproves their hypothesis?
This is normal in science! The scientist should accept that the hypothesis was incorrect, analyze why, and form a new hypothesis to test.
