Natural science essays study and describe natural phenomena. Based on experiments and observations, scientists discover laws and propose theories. They also use mathematics and logic to make correct conclusions, so they are capable of predicting some events.
Natural science is a broad term that includes several distinct disciplines. Some specialize in tiny objects, like microorganisms, elements, or atoms. Others explore the infinite space and ephemeral processes of life.
A more academic way to differentiate natural science is not based on the size of an object.
