Testable and non-testable questions

Why is it important to distinguish between testable and non-testable questions?

• It helps in formulating scientific inquiries that can lead to valid experiments and conclusions.

• It allows researchers to ignore irrelevant questions.

• It simplifies the process of data collection.

• It ensures that all questions can be answered definitively.

What type of question is 'Does adding plant food to soil make plants grow taller?'

• Testable

• Subjective

• Ambiguous

• Philosophical

Why can't 'What makes something sink or float?' be tested?

• It is a non-testable question because it involves complex principles of physics and density that cannot be answered with a simple experiment.

• It can be tested using a simple experiment with water and various objects.

• It is a straightforward question that can be easily answered by anyone.

• It requires advanced technology to measure the density of objects.

What is a testable question?

• A question that can be answered through experimentation or observation.

• A question that cannot be measured or tested.

• A question that is purely theoretical and has no practical application.

• A question that is based on personal opinion.

What is the role of observation in testable questions?

• Observation is crucial in testable questions as it helps gather data and evidence to support conclusions.

• Observation is only necessary for qualitative research and not for testable questions.

• Observation is irrelevant in testable questions since they rely solely on theoretical frameworks.

• Observation is used to formulate hypotheses but not to test them.

What is a non-testable question?

• A question that can be answered through experimentation.

• A question that involves measurable data.

• A question that cannot be answered through experimentation or observation.

• A question that is based on scientific facts.

What is an example of a scientific experiment related to testable questions?

• Testing how different amounts of water affect the growth of a bean plant.

• Observing the color of leaves in autumn.

• Measuring the temperature of water in different seasons.

• Counting the number of stars visible in the night sky.

How can you turn a non-testable question into a testable one?

• By rephrasing it to focus on measurable outcomes, such as 'How does the type of pet affect a person's happiness?'

• By making it more vague and open-ended.

• By removing any specific variables from the question.

• By asking for personal opinions instead of facts.

Can opinions be considered testable questions?

• Yes, opinions can be tested scientifically.

• No, opinions are subjective and cannot be tested or measured scientifically.

• Opinions can be tested through surveys and polls.

• Opinions can be measured using statistical methods.

Give an example of a testable question.

• How does the amount of sunlight affect the growth of a plant?

• What color is the sky on a clear day?

• Is water wet?

• Do plants prefer music over silence?
