A scientific investigation is a systematic process used to explore questions and test hypotheses about the natural world. It involves making observations, forming a question, and developing a hypothesis, which is a testable prediction. Researchers then design experiments or studies to gather data, analyze the results, and draw conclusions based on evidence. The goal of a scientific investigation is to increase understanding of a specific topic, such as climate change or human behavior. This process often includes collaboration among scientists and the use of tools and techniques from various fields, ensuring that findings are reliable and can be replicated by others.
