Study Notes
Hypotheses, Laws, and Theories
- Hypotheses and theories provide explanations for observations, while laws describe consistent natural phenomena.
- Predictions can be made using laws and theories, reflecting their established parameters.
Carbonated Beverages
- At cruising altitude, decreased air pressure around carbonated beverages can enhance fizzy sensations due to gas escaping more readily.
Differences Between Legal and Scientific Laws
- Legal laws are established by lawmakers considering public opinion; scientific laws are derived from experimental observations.
- Legal laws can evolve based on societal change and may have exceptions; scientific laws are stable unless new evidence emerges.
Examples of Scientific Laws
- The gravitational force between objects is mathematically linked to their mass and distance, showcasing a fundamental scientific law.
Theories vs. Laws
- A scientific theory explains observations based on extensive data, whereas scientific laws are usually expressed in mathematical form.
Testability and Falsifiability
- Hypotheses, laws, and theories can all be tested and potentially falsified, reinforcing the scientific method.
Support from Observations
- Theories and laws are underpinned by a multitude of observations, establishing their reliability within scientific discourse.
Important Criteria for Hypotheses
- A hypothesis should be testable, falsifiable, and based on established knowledge rather than subjective opinions.
Scientific Method Procedures
- When experimental results contradict a theory, verification through repeated experiments is essential before any theory revision.
Role of Hypotheses
- A hypothesis can be revised based on experimental outcomes, indicating the dynamic nature of scientific research.
Impact of Disproven Theories
- When a theory is disproven, it contributes to scientific knowledge rather than being viewed as a failure.
Comparison of Laws and Theories
- Both laws and theories can be subjected to testing, emphasizing their scientific validity and importance in research.
