Scientific Method Concepts

The video tutorial introduces the scientific method, focusing on writing effective scientific claims, questions, and hypotheses. It explains the roles of manipulated, responding, and controlled variables. Students learn to formulate scientific questions and hypotheses using examples, and practice applying these concepts through scenarios. The session concludes with a reflection on key learnings.

What is the primary goal of the scientific method?

• To prove a hypothesis

• To answer questions using evidence

• To create new scientific laws

• To gather opinions from scientists

Which of the following is NOT a step in the scientific method?

• Opinion

• Claim

• Evidence

• Reasoning

What is a manipulated variable?

• A variable that is ignored

• A variable that is measured

• A variable that is changed

• A variable that stays the same

Which variable serves as a baseline comparison in an experiment?

• Experimental controlled variable

• Manipulated variable

• Controlled variable

• Responding variable

What must a scientific question include to be valid?

• Only responding variables

• Manipulated and responding variables

• Only manipulated variables

• Opinions and beliefs

What is the purpose of a scientific question?

• To summarize the experiment

• To serve as the focus of an investigation

• To provide a hypothesis

• To list all variables

Which of the following is an example of a scientific question?

• Plants need water to survive

• Plants grow in sunlight

• If a plant is watered more, will it grow taller?

• Watering plants is important

How should a hypothesis be structured?

• As a statement of fact

• In an if-then-because format

• As a list of variables

• As a question

What is the main difference between a scientific question and a hypothesis?

• A question asks if something will happen, a hypothesis predicts what will happen

• A question is based on opinion, a hypothesis is based on fact

• A question includes variables, a hypothesis does not

• A question is a statement, a hypothesis is a question

What is a hypothesis?

• A random guess

• A statement of fact

• A prediction based on evidence

• An opinion about an experiment
