Exploring Claim Evidence Reasoning Techniques

Mrs. Murdock introduces the Claim, Evidence, Reasoning (CER) framework, a method for analyzing scientific experiments. She explains that a claim is a statement connecting an experiment's independent and dependent variables, similar to a hypothesis but made after the experiment. Evidence involves listing specific data supporting the claim, while reasoning requires explaining how and why the data supports the claim. The video uses an example of mice navigating a maze to illustrate these concepts, emphasizing the importance of understanding the underlying scientific principles.

What does CER stand for in scientific analysis?

• Claim, Evidence, Reasoning

• Claim, Experiment, Result

• Conclusion, Evidence, Research

• Claim, Evidence, Research

At what point in the scientific process is a claim made?

• Before analyzing the results

• After the experiment

• During the experiment

• Before the experiment

What is the main purpose of a claim in the CER process?

• To describe the experiment

• To connect the independent variable to the dependent variable

• To list the materials used

• To explain the hypothesis

In the given example, what is the independent variable (IV)?

• The maze

• The speed of the mice

• The type of food given to the mice

• The number of mice

What type of data is used in the 'Evidence' step?

• Hypothetical data

• General observations

• Specific data supporting the claim

• Background information

In the example, what qualitative evidence is provided?

• The experiment was timed

• The mice were of the same species

• The maze had many dead ends

• The mice that ate food A went twice as fast through the maze as those that ate food B

What is the most challenging part of the CER process according to the video?

Why is reasoning considered the hardest part of the CER process?

• It does not require any research

• It involves explaining and justifying the data

• It requires repeating the claim and evidence

• It is the first step in the process

What is the reason given for why mice on food A navigated the maze faster?

• Food A had more complex carbohydrates

• Food A was tastier

• Food A was given in larger quantities

• Food A had more simple sugars like glucose and fructose

What is the final step in the CER process?

• Explaining the reasoning

• Summarizing the experiment

• Collecting evidence

• Making a claim
