Study Notes
The Scientific Method
- Observation: The starting point of the scientific method, using senses to describe an object.
- Classification: Placing observations into groups based on shared characteristics.
- Inference: Using logical reasoning to draw conclusions from observations.
- Measurement: Quantifying observations to gain a more precise understanding.
- Problem Identification: Recognizing a question or issue arising from observations.
- Hypothesis: A possible explanation for an observation, which can be tested.
- Experimentation: Designing and carrying out tests to evaluate a hypothesis.
- Results: The outcomes of an experiment, used to support or refute the hypothesis.
- Theory: A well-supported explanation for a phenomenon, based on repeated experimental verification of related hypotheses.
- Law or Principle: A statement describing a consistently observed pattern in nature, often derived from a well-established theory.
- Controlled Experiment: A parallel experiment where all factors except the one being tested are kept constant, ensuring a reliable comparison.
