Such fact-supported theories are not "guesses" but reliable accounts of the real world. hypothesis implies insufficient evidence to provide more than a tentative explanation. A hypothesis is an educated guess about what you think will happen in a scientific experiment, based on your observations. However, a theory has been tested using the scientific method many times. MarisaAlviar-Agnew(Sacramento City College). A hypothesis is a tentative explanation that can be tested by further investigation. (NLM) I . In quantum mechanics, matter is believed to behave both like a particle and a wave at the sub-microscopic level. A hypothesis is either a suggested explanation for an observable phenomenon, or a reasoned prediction of a possible causal correlation among multiple phenomena. What do these terms mean to you? Note some key features of theories that are important to understand from this description: Scientific laws are similar to scientific theories in that they are principles that can be used to predict the behavior of the natural world.
