Visual observation is the process of gathering information by looking at objects, events, or behaviors. It involves using one's eyes to notice details such as color, shape, size, and movement. This method is commonly used in various fields, including science, education, and everyday life, to collect data without relying on instruments or tools. In scientific research, visual observation can help identify patterns or changes in subjects, such as animals in their natural habitat or plants during different growth stages. It is a fundamental skill that enhances understanding and supports further investigation or analysis.
