A scientific investigation begins with certain observations. By seeing these observations, a question is made. To answer the question, a hypothesis is generated. A hypothesis is a tentative statement that can either be stated s correct or wrong. To test the hypothesis, experiments are made and results are deduced from the experiments. Based on these results, a hypothesis can be proved as correct or wrong. These results are then communicated to check for their authenticity.
