Ascientist noticed that a dark-colored peppered moth is more visible on a light-colored background than a light-colored peppered moth. he wonders, “does this difference in visibility affect the survival rate of dark moths? ” which part of the scientific method does he need to carry out next?

Form a hypothesis

A scientific way to investigate a problem involves mainly five steps.

→A question or problem must be formulated in the first step.

→After gathering the background information, A hypothesis must be made.

→Third step would be to design an experiment.

→Fourth step would include collection and recording of data.

→Fifth step would include the conclusions drawn from the experiment and communication of hypothesis and its results.

When  the scientist notices that a dark colored peppered moth over light colored background, he formulates a question: whether the difference in visibility affects the survival rate of dark moths or not? Therefore, next step in the scientific method would be to gather more information on the subject and formulate a hypothesis.

they should be similar or the same

it is called kinetic energy
