1. Observation: This is the most fundamental way scientists gather information. It involves carefully watching and recording what happens in the natural world. This can be done through direct observation (like watching a bird's behavior) or through using instruments like microscopes, telescopes, or sensors. Observations are used to form hypotheses, gather data, and confirm theories.
2. Experimentation: Experiments are designed to test specific hypotheses in a controlled environment. They involve manipulating variables and observing the resulting changes. This allows scientists to isolate cause and effect relationships and draw conclusions about how things work. Examples include testing a new medicine on a group of patients or measuring the growth of plants under different lighting conditions.
