Observational science is a branch of scientific research that focuses on gathering data through direct observation rather than experimentation. This approach is often used in fields like astronomy, ecology, and geology, where researchers study natural phenomena in their real-world settings. By carefully recording what they see, scientists can identify patterns, make predictions, and develop theories based on their findings. In observational science, the emphasis is on collecting qualitative and quantitative data without manipulating variables. This method allows scientists to gain insights into complex systems, such as climate change or animal behavior, by observing how they function in their natural environments.
