Reviewing the Scientific Method

The video explains the scientific method, a systematic approach to understanding the physical world. It outlines the steps: observation, questioning, hypothesis formulation, testing, and conclusion. Using Alexander Fleming's discovery of penicillin as an example, it illustrates how observations lead to questions, hypotheses, and experiments, ultimately resulting in groundbreaking conclusions.

What is the first step in the scientific method?

• Making an observation

• Formulating a hypothesis

• Conducting an experiment

• Analyzing data

What question did Fleming ask after observing the mold?

• How can mold be grown on glass plates?

• How does bacteria grow on glass plates?

• What is the chemical composition of mold?

• Why is the moldy area free of bacteria?

Which type of reasoning is described as a bottom-up approach?

• Deductive reasoning

• Inductive reasoning

• Comparative reasoning

• Descriptive reasoning

What type of investigation involves comparing two objects or phenomena?

• Descriptive investigation

• Comparative investigation

• Hypothetical investigation

• Experimental investigation

What was the outcome of Fleming's experiment?

• The mold was a new type of bacteria

• The mold produced a substance that killed bacteria

• The bacteria grew faster near the mold

• The mold had no effect on bacteria
