Final answer:
Science is a distinctive way of gaining knowledge about the natural world through evidence and logic. It includes physics, chemistry, biology, and astronomy. The natural sciences can be divided into life sciences and physical sciences, and the field of science can be separated into more specific disciplines.
Step-by-step explanation:
Science is a distinctive way of gaining knowledge about the natural world that starts with a question and then tries to answer the question with evidence and logic. It is a practice of learning about the natural world, and includes physics, chemistry, biology, geology, and astronomy. Science uses mathematics and logic, and makes observations and experiments to produce accurate facts, scientific laws, and theories.
There is no complete agreement when it comes to defining what the natural sciences include. Some experts divide natural sciences into life sciences, which study living things and include biology, and physical sciences, which study nonliving matter and include astronomy, physics, and chemistry. Some disciplines build on both life and physical sciences and are interdisciplinary.
The field of science has gotten so big that it is common to separate it into more specific fields such as mathematics, physics, astronomy, chemistry, biology, geology, and more. These fields are not always completely separate as the boundaries between them are not always readily apparent. Scientists may study the chemistry of biological organisms and be labeled as biochemists.
