For many years, experiments showed that light had wave-like properties. For this reason, scientists described light as a wave. More recently, experiments produced data that could not be explained by the wave theory of light. The idea of particle properties was introduced.Why did the theory of light change over time?

Ana is planning to build an electrical circuit. Before building it, she writes the statement, "If four batteries are connected to a light bulb, then the light bulb will burn longer than if two batteries are connected because more batteries provide more energy."Which best explains why Ana's statement is a hypothesis rather than a theory?

Which hypothesis will most likely lead to further investigation and, potentially, a theory?

Jorge is testing the effect of lead on child development. Based on his observations, he finds that the longer the children are exposed to lead-based paint, the higher the chance becomes that the children may develop behavioral problems. He has done repeated experiments, and his results are similar to the results of many other scientists.Why is this scenario considered a theory rather than a hypothesis?

How is a theory different from a law?
