Document Summary
Questions science cannot address: no supernatural explanations, science does not make moral judgements, science does not male aesthetic/value judgements, qualitative data information about qualities; information that can"t actually be measured. Quantitative data expressing a certain quantity, amount or range: observational science investigations which are purely descriptive & no ability to manipulate variables. Hypothesis driven science using experiments to test hypothesis: manipulative experiment based on direct manipulation of independent variables. Natural experiment no manipulated variables but not all variables are kept constant: controlled variables experimental element which is constant and unchanged throughout the course of the investigation. Hypotheses are tested through experimentation which creates a theory: correlation two or more variables fluctuate together. A field, practice, or body of knowledge can reasonably be called pseudoscientific when it is presented as consistent with the norms of scientific research; while failing to meet these norms. : isotope same element, different atomic mass. Radioactive isotope nucleus decay, spontaneous releasing high-energy electromagnetic radiation.
