Science is ultimately based on observation (perceiving objects or events using one of the five senses)
Observations often lead to questions ---> which lead to experiments to answer the questions.
The common steps that biologists and other scientists use to gather information and answer questions
an explanation for a question or a problem that can be formally tested
What is a controlled experiment?
Setting up a test in duplicate- involves two groups: the control group and the experimental group
~controlled by the experimenter
Based on the data, a scientist then determines whether the hypothesis was supported or refuted. Be careful here, scientists usually don't use the word "prove" because there are no absolutes in science. In science, every conclusion must assume that the conclusion is only "true to the best of our knowledge". This is an important distinction between science and other subjects. Science is subject to change when new evidence is found. And while experimentation and observations can provide strong evidence for a conclusion, it is not absolute proof.
