Study OutcomesCheat Sheet
Colorful paper art promoting Ace CER Questions, a practice quiz for middle school science students.

What is the role of a claim in the CER framework?
It provides a concise answer to a scientific question based on evidence.
It records the methods and materials used in an investigation.
It lists all experiments conducted.
It serves as a summary of unrelated observations.
The claim is the statement or conclusion that answers the initial question. It defines the purpose of the investigation and sets the foundation for supporting evidence and reasoning.
Which part of the CER framework involves using facts, data, or observations to support a claim?
Evidence
Claim
Conclusion
Procedure
Evidence consists of the specific data, observations, or measurements collected during an investigation. It is used to back up the claim with concrete examples from the experiment.
Which component of CER explains how the evidence supports the claim?
Reasoning
Method
Evidence
Hypothesis
Reasoning connects the evidence to the claim by describing the logic and underlying principles that justify the conclusion. It shows the relationship between the data and the proposed explanation.
Why is it important to include evidence in a CER argument?
Because it supports the claim with factual information.
Because it serves as a conclusion to the experiment.
Because it explains unnecessary details.
Because it replaces the need for a detailed claim.
Evidence provides the factual basis that supports a claim in a CER argument. Without evidence, the claim would lack the necessary backing to be considered valid.
What does the acronym CER stand for in scientific argumentation?
Claim, Evidence, Reasoning
Conclusion, Experiment, Result
Control, Experiment, Review
Cause, Effect, Reaction
CER stands for Claim, Evidence, Reasoning, which is a structure used to develop and communicate scientific arguments clearly. It helps organize thoughts and supports conclusions with appropriate data.
Which of the following is an example of a claim in a scientific experiment?
I watered the plants daily.
I observed the plants closely.
Plants need sunlight to grow.
The experiment was conducted in a lab.
A claim is a testable statement that serves as the conclusion or answer to a scientific question, such as stating that plants need sunlight to grow. The other options provide details that might be part of the evidence or methods, not the claim itself.
How does reasoning differ from evidence in the CER framework?
It summarizes the results without analysis.
It provides raw data collected during experiments.
It explains the connection between evidence and the claim.
It lists the materials used in the experiment.
Reasoning bridges the gap between the evidence and the claim by providing the logic behind the connection. Unlike evidence, which is raw data, reasoning explains why that data supports the claim.
Which statement best demonstrates the use of evidence in a CER argument?
The data showed that water temperature rose, indicating a relationship between light and heat.
The materials used were standard for all experiments.
The experiment was conducted in a controlled environment.
I believe that light has an effect on temperature.
A strong use of evidence explicitly presents data or observations that support the claim. The selected option provides a clear link between collected data and the observed phenomenon, which is central to the evidence component.
Why is linking evidence with reasoning crucial in making a scientific argument?
It solely focuses on the data collection methods.
It replaces the need for a detailed claim.
It demonstrates how the evidence logically supports the claim.
It increases the length of the argument without adding value.
Linking evidence with reasoning helps clarify the logical steps that connect observations to the claim. This connection is essential to demonstrate the validity and reliability of the scientific argument.
Which example best represents a complete CER argument?
Plants grow well, and I like it when they are healthy.
The experiment was fun and the lab was well-equipped.
The plant grows faster because it receives more sunlight; data showed a 20% increase in growth when exposed to sunlight, supporting the claim that sunlight enhances growth.
It is important to study plants because they are interesting.
A complete CER argument clearly states a claim, provides supporting evidence, and offers reasoning that logically connects the evidence to the claim. The chosen option meets all these criteria.
What is the primary purpose of the claim in a CER argument?
To answer the scientific question with a clear, testable statement.
To detail the experimental procedure.
To list all observed data collected during the experiment.
To describe the limitations of the study.
The claim is the core assertion of the argument that provides an answer to the scientific question. It is concise, testable, and serves as the foundation upon which evidence and reasoning are built.
Which of the following is an example of misusing evidence in a CER argument?
Presenting multiple data points from repeated experiments.
Citing findings from peer-reviewed studies.
Including evidence that is derived from controlled experiments.
Using personal opinions instead of reliable measurements.
Scientific arguments should rely on objective data rather than personal opinions or anecdotal observations. Using personal opinions undermines the reliability of the evidence and weakens the argument.
What is the significance of a testable claim in the process of scientific investigation?
It makes the argument applicable to every scientific field.
It eliminates the need for further analysis.
It allows the argument to be validated or refuted through experimentation.
It ensures that the experiments will always produce positive results.
A testable claim is one that can be supported or refuted through experimentation, making it a critical component in developing robust scientific arguments. It directs the focus of the investigation and helps in designing appropriate experiments.
Which component of CER explains why the evidence directly supports the claim in a scientific argument?
Evidence
Reasoning
Conclusion
Observation
The reasoning component explicitly details the connection between the evidence and the claim, explaining the underlying logic of how the evidence supports the conclusion. This is crucial in making a convincing scientific argument.
How does clarity in presenting CER components improve scientific communication?
It makes the argument unnecessarily simplistic.
It focuses only on the claim without supporting evidence.
It ensures that the logical connection between the claim, evidence, and reasoning is easily understood.
It limits the discussion to experimental procedures.
Clear presentation of each component in the CER structure allows others to follow the logical progression of the argument. By clearly linking the claim, evidence, and reasoning, scientific communication becomes more effective and persuasive.
A scientist claims that increasing the amount of fertilizer leads to faster plant growth. Which of the following is the best example of reasoning to support this claim?
Fertilizer makes plants look healthier.
All plants were planted in the same type of soil.
The experiment measured a 15% increase in plant height with increased fertilizer, aligning with known theories on nutrient uptake and growth.
The study was conducted over several weeks.
Option A provides a quantified observation and connects it to established scientific principles about nutrient uptake, exemplifying robust reasoning. The other options either lack quantitative evidence or do not explain the causal relationship.
In constructing a CER argument, how can one critically assess the validity of the evidence?
By focusing solely on the experimental results.
By accepting all data collected during the experiment as automatically valid.
By using only evidence that clearly supports the claim regardless of its origin.
By evaluating the source of the evidence, the data collection methods, and its consistency with established scientific knowledge.
Critical assessment of evidence involves careful evaluation of its source, collection methods, and alignment with existing literature. This thorough review ensures that the evidence used reliably supports the claim.
If a CER argument claims that water pollution is caused by industrial discharge, which reasoning flaw could significantly undermine this argument?
Citing experimental evidence from water quality tests.
Including data on chemical contaminants from industrial sources.
Assuming that all water pollution results solely from industrial discharge without considering other sources like urban runoff.
Comparing data from multiple polluted sites.
The reasoning flaw in this context is the failure to consider alternative sources of water pollution, such as urban runoff. Ignoring other potential causes can lead to an oversimplified and biased argument.
Which strategy most effectively enhances the quality of reasoning in a CER argument?
Providing unrelated background information.
Presenting evidence without explaining its relevance.
Explicitly linking the evidence to the claim using detailed explanations and addressing potential counterarguments.
Repeating the claim multiple times to emphasize it.
A strong reasoning strategy involves directly connecting evidence to the claim and anticipating counterarguments. This approach makes the argument more robust, logical, and convincing.
Why is it important to consider alternative explanations when evaluating a CER argument?
It distracts from the main claim.
It makes the argument unnecessarily complicated and confusing.
It only strengthens the case for the alternative explanations.
It reduces confirmation bias and strengthens the argument by demonstrating that the evidence robustly supports the claim over competing explanations.
Considering alternative explanations helps in critically analyzing whether the evidence uniquely supports the claim or if other factors could be responsible. This process minimizes bias and enhances the credibility of the argument.
