Mastering the Scientific Method for the NYS Living Environment Exam

This video tutorial introduces the scientific method as a systematic approach to solving problems. It covers the importance of scientific inquiry, the distinction between facts, theories, and laws, and the steps involved in the scientific method. The tutorial emphasizes the need for valid experiments, including the use of control groups and large sample sizes. It concludes with a summary of key points and preparation tips for exams.

• A fact that cannot be argued

What is the first step in the scientific method?

• Making observations

• Conducting research

• Forming a hypothesis

• Stating the problem

What is a hypothesis?

• A question about the problem

• A prediction about the possible answer to the problem

• A conclusion based on data

• An observation made during an experiment

What is the purpose of a control group in an experiment?

• To test multiple variables
