<h3>Explanation:</h3>
Scientific method is the protocol in an experiment for a hypothesis that involves testing, measurement, observation and necessary modification of hypothesis during the course of the experiment. There are several manners and experiments that can be tested for the hypothesis, and plenty of ways to design an experiment.
Scientific experiments can be very tricky to design, owing to the numerous parameters and variables that need to be accounted for. Of course, there are some relatively simple experiments. Creativity is needed for all branches of science, because each field presents obstacles in discovery, and creativity allows for us to devise ways around those obstacles. Science has always tested humans ability to think outside the box and question their surroundings, and creativity has been the driving force.
Hope this helps!
