Scientific Method Concepts

Mr. Philip explains the scientific method, a systematic approach used by scientists to solve problems and answer questions. The process involves identifying a problem, conducting observations and research, forming a hypothesis, conducting experiments, analyzing results, and forming conclusions. The video emphasizes the importance of testable hypotheses, controlled experiments, and the iterative nature of scientific inquiry. It also distinguishes between scientific theories and laws, highlighting their roles in predicting and explaining phenomena.

What is the primary purpose of the scientific method?

• To avoid using past experiences

• To conduct random experiments

• To solve problems and answer questions

• To memorize scientific facts

What is the first step in the scientific method?

• Conducting an experiment

• Formulating a hypothesis

• Analyzing data

• Identifying a problem or purpose

Which of the following is NOT a method of conducting research?

• Reading books

• Guessing the outcome

• Using past experiences

• Using the internet

How should a hypothesis be structured?

• Using 'if-then' statements

• As a statement of fact

• As a question

• As a list of variables

What is a key characteristic of a good hypothesis?

• It is testable

• It is complex

• It is unchangeable

• It is based on assumptions

What is the role of a control in an experiment?

• To change the outcome

• To ensure all variables are constant

• To serve as a standard for comparison

• To introduce new variables

What is an independent variable in an experiment?

• A variable that remains constant

• A variable that is measured

• A variable that is ignored

• A variable that is changed by the scientist

What should be done if the hypothesis is proven incorrect?

• Publish the incorrect hypothesis

• Ignore the results

• Stop the research

• Refute the hypothesis and form a new one

What is required for a hypothesis to become a theory?

• It must be proven once

• It must be simple and easy to understand

• It must be widely accepted without testing

• It must be repeatedly tested and confirmed

What is the difference between a scientific theory and a law?

• A law is unchangeable, while a theory is not

• A theory is a guess, while a law is a fact

• A law predicts behavior, while a theory explains why it happens

• A theory predicts behavior, while a law explains why it happens
