Answer:
1-creating a hypothesis
Step-by-step explanation:
The scientific method (or scientific process) is a set of basic rules to develop an experience in order to produce new concepts, also to correct and integrate existing knowledge.
Drawing a conclusion is the last step and designing an experiment certainly come after knowing what is being experimented. Before that, you must research about whatever is that you are studying and that research (or investigation) only happens once you had an idea to investigate, which means that first, you need a hypothesis.
