Summary Introduction
Introduction:
Science is a method of knowing and an approach to comprehending the natural world. It came about as a result of human curiosity about other life forms, themselves, the planet, and the universe.
Science is inquiry, the pursuit of knowledge and rationales for natural occurrences. Science involves aspects of difficulty, luck, and chance in addition to meticulous preparation, logic, creativity, patience, and the fortitude to overcome obstacles.

Students have asked these similar questions
which of the following best describes the logic of scientific inquiry?
a. If I generate a testable hypothesis, tests and observations will support it.
b. If my prediction is correct, it will lead to a testable hypothesis
c. If my observations are accurate, they will support my hypothesis.
d. if my prediction is correct, my hypothesis is supported.
Why is forming a hypothesis an important step in the scientific method?
Choose the best answer.
Stating a hypothesis before conducting experiments ensures that the method will
follow an inductive process of reasoning.
By stating a formal hypothesis, a scientist can adequately design the best control
conditions for designing experiments intended to falsify the hypothesis.
When a formal hypothesis is tested once, it will be accepted as theory no matter
what the results of subsequent experiments suggest.
A useful hypothesis typically accomplishes these two things:
Group of answer choices
it is falsifiable and clear
it clearly establishes a null hypothesis and it generates a testable prediction
it can be easily disproved and will be considered a theory if not disproved
it frames an experiment that can shed light on the observation and guides design of the experiment

- Formulate three (3) hypotheses.Hypothesis: cause and effect/premise and prediction - ”If..then..” statements Example: “If the glass is tapped, then the fish will swim away” There are four evaluation criteria that a hypothesis must meet. First, it must state an expected relationship between variables. Second, it must be testable and falsifiable; researchers must be able to test whether a hypothesis is true or false. Third, it should be consistent with the existing body of knowledge. Finally, it should be stated as simply and concisely as possible.arrow_forwardHow do scientists derive testable hypotheses?

From this observation, what is a testable hypothesis? What is your prediction based on your hypothesis? Please design an experiment to test this hypothesis and prediction.
