Scientific Inquiry and Testable Questions

Mr. Andersen's mini lesson focuses on developing testable and investigative questions related to natural phenomena. The video guides viewers through identifying phenomena, formulating questions, and determining their scientific validity. Using examples like Newton's Cradle and rattlebacks, the lesson demonstrates how to create investigative questions and make predictions. The goal is to enable viewers to ask meaningful scientific questions and plan investigations, emphasizing the importance of testable questions in science.

What is the primary focus of asking questions in scientific inquiry?

• To avoid scientific methods

• To link questions to natural phenomena

• To entertain the audience

• To confuse the learners

Which of the following is NOT a scientific question?

• How does the release height affect motion?

• What happens if more than one sphere is launched?

• Did Newton invent the Cradle?

• How does temperature affect the speed of sound?

What is an investigative question?

• A question that has no answer

• A question that involves changing a variable

• A question that cannot be tested

• A question that is purely theoretical

What is the purpose of making predictions in scientific investigations?

• To confuse the results

• To anticipate outcomes based on changes

• To avoid conducting experiments

• To guess randomly

What happens when you increase the number of spheres released in Newton's Cradle?

• The spheres stop moving

• The spheres change color

• The number of spheres moving on the opposite side increases

• The spheres move in a circular motion

What is a rattleback?

• A device that rattles and changes direction

• A device that does not move

• A device that spins only clockwise

• A device that spins indefinitely

Which question about rattlebacks is NOT testable?

• Is it a magnetic phenomenon?

• Why does it want to spin counterclockwise?

• How does adding weight affect its motion?

• Are the rattlebacks unequally weighted?

What can be done to test if rattlebacks are unequally weighted?

• Spin them faster

• Add weights to one side

• Change their color

• Use a different material

What is the significance of testable questions in science?

• They are not important

• They are only for entertainment

• They are used to confuse scientists

• They help in planning investigations

What additional practice is suggested at the end of the lesson?

• Ignoring the lesson

• Reading a textbook

• Asking questions about drinking birds and bubble levitators

• Watching more videos
