Descriptive science is about observing and describing things that we see in the world around us. It helps us learn more about the world, and it is usually the first step that scientists take when studying something new. For example, if a scientist wants to learn more about a new animal they might look at the animal carefully and describe its size, shape, color, habits, and other features. This is a form of descriptive science. By understanding the animal better, the scientist can then take the next step and study how it behaves, how it grows, and other changes.
