The Scientific Method

The video explains the scientific method, starting with observation and questioning, as demonstrated by Alexander Fleming's discovery of penicillin. It covers formulating hypotheses using inductive reasoning, testing them through deductive reasoning, and analyzing data to draw conclusions. Fleming's work on bacteria and mold illustrates these steps, leading to the creation of the first antibiotic.

What is the first step in the scientific method?

• Formulating a hypothesis

• Conducting an experiment

• Analyzing data

• Making an observation

What question did Fleming ask after observing the mold?

• Why is the moldy area free of bacteria?

• How can mold be grown faster?

• What is the color of the mold?

• Is the mold harmful to humans?

What reasoning method is used to form a hypothesis?

• Inductive reasoning

• Descriptive reasoning

• Deductive reasoning

• Comparative reasoning

What is the purpose of conducting an experiment in the scientific method?

• To prove a hypothesis correct

• To gather evidence to support or refute a hypothesis

• To create new hypotheses

• To observe natural phenomena

What was the outcome of Fleming's experiment?

• The mold changed color

• The mold was ineffective against bacteria

• The mold produced a substance that killed bacteria

• The bacteria grew faster near the mold
