Crafting Scientific Explanations with Claim Evidence and Reasoning

The video tutorial explains how to write scientific explanations using the Claim, Evidence, and Reasoning (CER) format. It begins with formulating a scientific question, followed by conducting research and experiments to gather data. The tutorial then guides viewers on crafting a claim, supporting it with evidence, and connecting the evidence to the claim using reasoning. The final step is to compile these elements into a coherent paragraph. The video emphasizes the importance of using specific data and scientific principles to validate claims.

What is the primary purpose of using the Claim, Evidence, and Reasoning format in scientific explanations?

• To make explanations more entertaining

• To ensure explanations are based on observations and logical reasoning

• To simplify complex scientific theories

• To avoid using scientific principles

When starting a scientific explanation, what is the first step according to the CER format?

• Gathering evidence

• Writing the reasoning

• Formulating a question about a phenomenon

• Conducting experiments

What should a claim in a scientific explanation include?

• Words from the question being addressed

• A summary of unrelated scientific principles

• A list of all possible outcomes

• A detailed description of the experiment

Why is it important to include numerical data in the evidence section of a scientific explanation?

• To confuse the reader

• To avoid using scientific terms

• To provide validity and clarity to the evidence

• To make the explanation more colorful

Which of the following is a better evidence statement?

• The car went faster when the ramp was higher.

• The ramp height was changed during the experiment.

• The car's speed was affected by the ramp height.

• According to the data, when the ramp height increased from 10 cm to 20 cm, the car's speed increased from 3 cm/s to 5 cm/s.

What role does reasoning play in the CER format?

• It describes the materials used in the experiment.

• It connects the evidence to the claim using scientific principles.

• It provides a summary of the experiment.

• It lists all possible outcomes of the experiment.

How does friction affect the movement of a soccer ball on different surfaces?

• Friction slows down the ball on rough surfaces.

• Friction has no effect on the ball's movement.

• Friction speeds up the ball on rough surfaces.

• Friction makes the ball move in a zigzag pattern.

What is the scientific principle used to explain why a soccer ball travels faster on synthetic turf?

• Magnetism

• Buoyancy

• Friction

• Gravity

What should you check after writing all three sections of a CER explanation?

• That the claim uses the same words as the question

• That the evidence includes actual numbers from the data

• That the reasoning links the evidence to the claim using the correct scientific principle

• All of the above

What is the final step in the CER process?

• Conducting more experiments

• Putting all sections together in one paragraph

• Revising the question

• Adding more evidence
