Essential Question:

Why is providing evidence important when making claims in science using the CER method?

Providing evidence is important when making claims in science using the CER (Claim-Evidence-Reasoning) method because it strengthens the validity and credibility of the claims. Science is based on the systematic gathering and analysis of evidence to support or refute hypotheses, theories, and claims. By presenting evidence, scientists can demonstrate the reliability and reproducibility of their findings.

1. Establishes Credibility and Reliability: Evidence provides a foundation for scientific claims and makes them more credible. It shows that the claim is not merely an opinion or speculation but is supported by empirical data. Scientists can use various types of evidence, such as observational data, experimental results, or research studies, to validate their claims. By including evidence, scientists establish themselves as trustworthy sources and increase the confidence of their peers and the wider scientific community.

2. Supports the Claim: Evidence acts as the backbone of a claim in the CER process. It helps to substantiate the claim and provides a rational basis for accepting or rejecting it. Without evidence, claims would be baseless and unsupported by any concrete facts or observations. Evidence can be in the form of quantitative data, qualitative observations, or scientific literature that supports the claim.

3. Allows Reproducibility: In science, reproducibility is essential. It ensures that the findings can be independently verified and validated by other scientists. By including evidence, scientists enable others to replicate their studies or experiments to see if they obtain similar results. This process of reproducibility enhances the integrity and reliability of the scientific claims.

4. Facilitates Peer Review: Evidence is crucial for the peer review process in science. Peer review involves experts in the field critically evaluating and critiquing the claims and methodologies presented in scientific research. Including evidence in a claim helps reviewers assess the validity of the claim and determine the quality of the underlying evidence. Critiques and suggestions provided during peer review can further strengthen the claim and help refine the scientific process.

5. Encourages Logical Reasoning: Evidence in the CER method encourages logical reasoning behind making a claim. The evidence is used to support the reasoning or logical argumentation made to arrive at the claim. It helps scientists provide a coherent explanation that connects the claim with the evidence. This logical reasoning is crucial for making informed conclusions and advancing scientific knowledge.

In summary, providing evidence is crucial when making claims in science using the CER method because it establishes credibility, supports the claim, enables reproducibility, facilitates peer review, and encourages logical reasoning. Evidence ensures that scientific claims are based on reliable data and can withstand critical scrutiny, leading to the advancement of scientific knowledge.

Step 1: The CER method

The CER method is a widely used approach in science for making claims, providing evidence, and explaining reasoning. CER stands for Claim, Evidence, and Reasoning. It ensures that scientific explanations are supported by evidence and logical reasoning.

Step 2: Making Claims

In science, a claim is a statement that answers a specific question or addresses a particular problem. It should be a clear and concise statement that can be supported or refuted through evidence.

Step 3: Providing Evidence

Evidence is the data, facts, and observations that support a claim. It can be quantitative (numerical data) or qualitative (descriptive data). Providing evidence is essential in science to back up claims and validate the conclusions drawn from experiments or observations.

Step 4: Importance of Evidence in Science

1. Support for Claims: Evidence helps validate the accuracy and reliability of claims made in science. It provides a foundation for the claim, making it more credible and convincing.

2. Reproducibility and Verification: Providing evidence allows others to replicate the experiments or observations to validate the claims independently. It ensures that scientific findings can be verified and trusted.

3. Objectivity and Peer Review: Evidence-based claims promote objectivity in science. Other scientists can examine the evidence and evaluate the validity of the claims through a process called peer review, ensuring scientific rigor.

4. Building Knowledge and Understanding: Evidence contributes to the accumulation of scientific knowledge. It helps scientists develop a deeper understanding of phenomena, theories, and concepts.

Step 5: Reasoning

The third component of the CER method is reasoning. It involves explaining the logical connections between the claim and the evidence provided. Reasoning helps scientists draw conclusions and make inferences based on the evidence presented.

Step 6: Conclusion

Providing evidence when making claims in science using the CER method is important because it ensures the accuracy, validity, and reliability of scientific explanations. Evidence supports claims, allows for verification and reproducibility, promotes objectivity, and contributes to building scientific knowledge and understanding.
