The universally-accepted, organised approach to the study of science, which consists of the following steps:
1. Observation – collecting data.
2. Hypothesis – forming a preliminary possible explanation of the data.
3. Testing – test the hypothesis by collecting more data.
4. Results – interpreting the results of the test and deciding if the hypothesis should be rejected. The hypothesis is rejected if the results contradict it, showing that it is wrong.
5. Conclusion – stating a conclusion that can be evaluated independently by others.
