Are all science activities called experimenting yes or no?
Science often involves making observations and developing hypotheses. Experiments and further observations are often used to test the hypotheses. Scientific inquiry often involves doing experiments, though not always.
What are natural and quasi experiments?
The difference is that in a quasi-experiment the criterion for assignment is selected by the researcher, while in a natural experiment the assignment occurs ‘naturally,’ without the researcher’s intervention. Quasi-experiments have outcome measures, treatments, and experimental units, but do not use random assignment.
