5. REAL LIFE SITUATION The 2004 Indian Ocean tsunami and the location of its epicentre REAL LIFE SITUATION The 2004 Indian Ocean tsunami and the location of its epicentre Presentation 1: Science and Prediction Tectonic theory explains occurrence of a sunami. Sunami occurs. Does that mean that prediction theory is valid? Could there be another reason for a sunami besides the movement of a tectonic plate. Identify a pattern and then you can make a prediction without needing to continuously test. Tectonic theory suggests that movements in the plates of the earth crust cause earthquakes under the ocean and this causes massive water surges leading a sunami. The story of the neutron and the atom. Scientific theory states that every atom has a nucleus. If you fire radiation at the centre of the atom then you can expect to have radiation rebound off the nucleus. This proves that atom has a neutron. If nothing comes back then the theory is invalid? Or maybe not. Maybe the conditions of the experiment were flawed. Eg problem with using wrong kind of radiation or a lack of precision in the measuring instrument.

REAL LIFE SITUATION The 2004 Indian Ocean tsunami and the location of its epicentre REAL LIFE SITUATION The 2004 Indian Ocean tsunami and the location of its epicentre KNOWLEDGE ISSUE To what extent does prediction test the validity of a scientific theory? KNOWLEDGE ISSUE To what extent does prediction test the validity of a scientific theory? Presentation 1: Science and Prediction KEY:Extraction Can you say that theory is valid if you can use it to make accuarte predictions? Theory = “atom has a nucleus”. Fire radiation at an atom. Some of the radiation will be deflected back because of nucleus. Is there some other reason the radiation would be returned? Do results agree with model? If they do then model might be true. It does not prove it 100% to be true. But I can disprove it? If Nothing comes when I fire radiation at the nucleus then atom has no nucleus.

KNOWLEDGE ISSUE To what extent does prediction test the validity of a scientific theory? Presentation 1: Science and Prediction General nature of scientific theory KEY:Extraction Development As long as expeiments agree with theory you keep the theory. If the results can’t be explained what do you do. Change the theory or modify experiment. Sunami tells you that Tectonic theory works. Is this true? Is it true because prediction works the theory then works also? The prediction that works validates the theory.

It is not possible to have a 100% perfect experiment. Therefore is it possible to justify the theory based on an imperfect experiment?
