Revising Scientific Explanations

Mr. Anderson's mini lesson focuses on constructing and revising explanations using evidence. The video guides viewers through the process of forming an initial explanation, gathering additional evidence, and revising the explanation with reasoning. Examples include a painted dog and a blue model in a container. The lesson emphasizes the scientific method of questioning phenomena and using evidence to form and refine explanations.

What is the primary goal when constructing explanations in science?

• To create new phenomena

• To memorize facts

• To ignore evidence

• To identify the cause of a phenomenon

In the painted dog example, what was the initial explanation based on?

• Personal opinion

• Available evidence

• Random guess

• Future predictions

What additional evidence was considered for revising the explanation of the painted dog?

• The dog's diet

• The dog's age

• The colors available and mixing tray

• The dog's breed

What was the revised explanation for the painted dog after considering new evidence?

• The dog painted itself

• The dog was painted by a machine

• Someone used mixed colors to paint the dog

• The dog was never painted

What is the initial explanation for the blue model in the container?

• The model assembled itself

• The model was assembled and then placed in the container

• The model was never assembled

• The model was assembled inside the container

What does the additional evidence suggest about the blue model in the container?

• The model is made of metal

• The model can be assembled inside the container

• The model is a single piece

• The model cannot be assembled

What role do magnets play in the revised explanation for the blue model?

• They make the model heavier

• They attract the pieces to self-assemble

• They repel the pieces

• They have no role

What is emphasized as crucial when revising explanations?

• Ignoring new evidence

• Using evidence and reasoning

• Relying on intuition

• Following tradition

What is suggested as a next step after learning to revise explanations?

• Forget the process

• Apply it to other examples

• Share it on social media

• Only use it in exams

What is the significance of the stickleback evolution example mentioned?

• It is a historical event

• It is an example to apply the learned process

• It is a complex puzzle

• It is unrelated to the topic
