provide a broader and deeper explanation for observations and laws. They are models of the way nature is, and they often predict behavior that extends well beyond the observations and laws on which they are founded. | Theory |
of John Dalton (1766–1844). Dalton explained the law of conservation of mass, as well as other laws and observations, by proposing that all matter was composed of small, indestructible particles called atoms. Dalton’s theory was a model of the physical | NEXT CARD |
world—it went beyond the laws and observations of the time to explain these laws and observations. | Atomic Theory |
The science that seeks to understand the behavior of matter by studying what atoms and molecules do. | Chemistry |
A procedure that attempts to measure observable predictions to test a theory or law. | Experiment |
A theory or law before it has become well established; a tentative explanation for an observation or a scientific problem that can be tested by further investigation. | Hypothesis |
A law stating that in a chemical reaction, matter is neither created nor destroyed. | Law Of Conservation of Mass |
Often the first step in the scientific method. Must measure or describe something about the physical world. | Observation |
A statement that summarizes past observations and predicts future ones. Are usually formulated from a series of related observations. | Scientific Law |
The way that scientists learn about the natural world. Involves observations, laws, hypotheses, theories, and experimentation. | Scientific Method |
A proposed explanation for observations and laws. Represents a model of the way nature works and predicts behavior that extends well beyond the observations and laws from which it was formed. | Theory |
