A hypothesis is a testable prediction or educated guess about the relationship between variables. A theory is a well-substantiated explanation of an aspect of the natural world, based on a body of evidence and repeated testing, but it can be modified as new evidence emerges. A law is a concise statement or mathematical equation that describes a consistent relationship observed in nature, often under specific conditions, without explaining why it occurs. Together, these concepts form the foundation of the scientific method, guiding research and understanding of natural phenomena.
