From the previous lesson, I have learned about confirmation and how to describe confirmation. A scientific explanation or finding can be learned through a scientific enquiry method. A scientific enquiry method is a way to ask and answer scientific questions by making observations and doing experiments. The steps in a scientific enquiry method is : -
- Identification and Definition of the Problem
- Formulation of the Hypothesis
- Collection, Organization and Analysis of Data
- Formulation of Conclusion
- Verification, Rejection or Modification of Hypothesis by the test of its consequences in a specific situation
Furthermore, we also learned about internal and external virtues. Internal virtues are features that do not depend on observations for evaluation. It depends on the consistency of the claims in a theory. However, external virtues are dependent on the observation of the experiment that is carried out. A theory that is made must be testable and the easiest way to test it is by observing through experimentation. However, theories are usually used for objects or events that are not amenable to observation. The theories do not test what can be observed with the naked eye or other five senses however the effects of the theories can be observed such as the effects of energy.
Moreover, we also learned about the basic model of confirmation which is a model that confirms a theory based on deductive reasoning. This model is called the hypothetical - deductive model of confirmation. This confirms a theory based on deductive reasoning which is, if the hypothesis is true, then the effect must happen and when the effect happens or can be seen, so the theory must be true. The presentation stated below further explains the hypothetical - deductive model.

There are also amendments made to the first model because there were only two components which are the hypothesis and effects. However, the conditions of the environment might affect the result. Therefore, the new model has three components :-
1. Hypothesis
2. Conditions of testing
3. Predicted effect
If the hypothesis is true and the conditions are right, the effect will be observed. The results might fail because the conditions were incorrect but that will not necessarily mean that the hypothesis itself is wrong. Therefore, it must be regularly tested in order to confirm the hypothesis.
From this chapter, i would need most help in memorizing the scientific enquiry method. This is because I have not familiarized myself with the steps. I would use this knowledge to be able to conduct experiments or teach my students to conduct experiments properly with the methods given.
