Verified step by step guidance1
Understand the definition of a scientific theory: A scientific theory is a well-substantiated explanation of some aspect of the natural world that is based on a body of evidence and has been repeatedly confirmed through observation and experimentation.
Differentiate between a theory and a hypothesis: A hypothesis is a proposed explanation for a phenomenon that can be tested, while a theory is a comprehensive explanation supported by a large body of evidence.
Recognize that scientific theories are not static: Theories can be modified or refined as new evidence becomes available, reflecting the dynamic nature of scientific understanding.
Identify the role of experimental support: Theories are supported by extensive experimental evidence, distinguishing them from mere guesses or speculations.
Apply this understanding to atomic theory: Atomic theory, like other scientific theories, is a well-substantiated explanation that has evolved over time with new discoveries and evidence, such as the development from Dalton's atomic theory to the modern quantum mechanical model.
