Module 6 – Capstone Design Biology Audit

Lesson 3: Writing Your Final Audit

This lesson shows you how to write the final capstone audit as a clear, disciplined document. Your goal is not to persuade with emotion. Your goal is to evaluate a claim with a process that another person can repeat.

A strong final audit reads like a structured investigation. It defines the claim, lays out the evidence, tests predictions, compares alternatives, and states what the evidence supports and what it does not.

Your final audit should be written so that a reader can answer one question. If I followed these steps, would I reach the same conclusion from the same evidence?

The Required Format

Your final audit should include these sections in this order.

Title
Claim Statement
Scope and Boundaries
Definitions
Evidence Summary
Severe Tests
Controls and Null Models
Alternative Explanations
Risky Predictions
Falsifiers
Findings and Conclusion
Limitations and Next Tests
References

Keep your writing direct. Keep paragraphs focused. Use short headings. Make your logic visible.

Step 1: Title and Claim Statement

Your title should name the claim being audited.

Example: “Audit of the Claim That X Can Produce Y Under Z Conditions.”

Your claim statement should be one to two sentences. It must be specific. It must include the proposed mechanism.

If your claim is vague, the entire audit becomes vague.

Step 2: Scope and Boundaries

State what you examined and what you did not examine.

Define the biological system. Define the time scale if relevant. Define which kinds of sources you used.

If your audit becomes too broad, you will lose depth and precision. Your capstone is about one claim, not the whole debate.

Step 3: Definitions

List the key terms in your claim and define them operationally.

Operational definitions explain how a term will be measured or recognized in evidence. Avoid dictionary definitions that do not change how you evaluate data.

Define words like:

information
function
regulation
control
system
random
selection
mechanism

If a term cannot be defined operationally, note that as a weakness in the claim.

Step 4: Evidence Summary

Present the evidence as observations first.

Separate:

What is measured from
What is interpreted

Use short paragraphs. Refer to specific experiments or findings. If data tables or figures exist, describe what they show in plain language.

Do not argue in this section. Report.

Step 5: Severe Tests

Now design or identify tests that the claim must pass.

A severe test challenges the claim at its core. It tries to expose failure, not just confirm success.

Explain why each test is severe. Explain what result would count as failure.

If you cannot describe a severe test for the claim, that is an important finding.

Step 6: Controls and Null Models

List what controls were used in the evidence and what controls should have been used.

Explain what the null model predicts if no special mechanism is operating.

Then state whether the evidence beats the null model in a meaningful way.

If the evidence does not exceed the null expectation, the claim is weaker than it appears.

Step 7: Alternative Explanations

List the strongest competing explanations.

Then test each alternative against the same evidence.

A strong audit does not create a strawman. It engages the best version of the alternatives and shows where they succeed or fail.

Step 8: Risky Predictions

Write what the claim predicts that competing explanations do not strongly predict.

Make these predictions specific and measurable.

Then check whether the evidence matches those expectations.

If the claim makes no risky predictions, it is not a strong scientific explanation.

Step 9: Falsifiers

State clearly what would falsify the claim.

Write at least one falsifier that is realistic and observable.

A claim that cannot be falsified is not being tested. It is being narrated.

Step 10: Findings and Conclusion

Now summarize the results.

Answer these questions plainly.

Did the evidence support the claim?
Did it support it strongly or weakly
Did the alternatives explain the evidence as well or better
Did the claim pass severe tests
Did it beat the null model

Your conclusion should fit the evidence you presented. Do not overstate.

Step 11: Limitations and Next Tests

Every audit has limits. State them.

Then propose the next best tests that would improve the evaluation.

Examples include:

better controls
broader data sets
more realistic conditions
different measurements
replication by independent groups

This section shows maturity. It also shows you are not trying to close the case by force.

Step 12: References

List your sources.

Prefer primary literature when possible. If you use summaries, identify them clearly.

Do not cite sources you did not read.

Submission Standard

Your final audit should be consistent, detailed, and repeatable.

If a reader can see your steps, your criteria, your tests, and your failure conditions, then you have done the assignment correctly.

In the next lesson, you will learn the submission guidelines and how your capstone will be assessed.

Lesson Summary

This lesson guides you through writing a final capstone biology audit as a clear, structured, and repeatable evaluation rather than an emotional argument. The audit systematically defines and tests a claim using evidence, controls, and alternatives to reach a valid conclusion.

Key Goals:

• Evaluate a specific scientific claim using objective tests and evidence.
• Create a transparent, logical investigation others can replicate.
• Avoid persuasion—focus on clear, direct writing and structured reasoning.

Required Format and Sections (in order):

• Title: Name the claim being audited, e.g., “Audit of the Claim That X Can Produce Y Under Z Conditions.”
• Claim Statement: One to two specific sentences including the proposed mechanism.
• Scope and Boundaries: Define what is and is not examined, system boundaries, time scale, and sources used.
• Definitions: Provide operational definitions for key terms that impact data evaluation.
• Evidence Summary: Present objective observations and measurements without interpretation or argument.
• Severe Tests: Identify robust tests designed to challenge and potentially falsify the claim.
• Controls and Null Models: List controls used and expected outcomes if no mechanism operates; assess whether evidence beats the null model.
• Alternative Explanations: Evaluate strongest competing explanations against the same evidence fairly.
• Risky Predictions: Describe specific, measurable predictions unique to the claim and compare with evidence.
• Falsifiers: Clearly state realistic and observable conditions that would falsify the claim.
• Findings and Conclusion: Summarize support for the claim, strength of evidence, comparison to alternatives, success of tests, and null model performance.
• Limitations and Next Tests: Acknowledge audit limitations and propose further studies or controls to improve evaluation.
• References: Cite primary literature and clearly identify any secondary sources used. Only cite what you have read.

Writing Tips:

• Keep writing direct, focused, and concise.
• Use short, clear headings for each section.
• Make reasoning transparent through stepwise logic.
• Separate factual evidence presentation from interpretation and evaluation.

Outcome: A well-constructed, detailed, and consistent audit enables readers to verify and possibly replicate your evaluation, strengthening scientific rigor and integrity.
