What is a possible explanation of a problem based on observation and prior knowledge?
A hypothesis is an idea that can be tested by an experiment-These ideas are based upon a person’s observations and previous knowledge or experience. A hypothesis is a possible explanation for a set of observations or an answer to a scientific question. A hypothesis could also be called an “educated guess”.
What is a testable prediction based on prior knowledge and observation?
A scientific hypothesis is the initial building block in the scientific method. Many describe it as an “educated guess,” based on prior knowledge and observation.
Which term is testable a prediction and can be supported or refuted by data?
A hypothesis is a tentative and testable explanation, based on observation(s). A hypothesis can be supported or refuted through experimentation or more observation. A hypothesis can be disproven, but not proven to be true.
What is the most difficult step in the scientific method?

What is least likely to occur after an experiment is conducted to test a hypothesis?
The hypothesis becomes a theory, if the results support is the least likely to occur after an experiment is conducted when testing a hypothesis. The results would still be further analyzed and if needs more experiment, then another experiment will be conducted to provide more data before it will become a theory.

What is it called when scientists in the same or similar?

Why do scientists need to repeat experiments?
Why is the ability to repeat experiments important? Replication lets you see patterns and trends in your results. This is affirmative for your work, making it stronger and better able to support your claims. This helps maintain integrity of data.
What is the first step of the scientific method?
