Unit 08 · Communicating & Defending Findings
A finding that nobody can follow changes nothing. This closing unit is about turning a finished investigation into something a reader can trust and a listener can question: a plain written report, a graph that actually backs the claim, and an out-loud defense that holds up when someone pushes back. A student lays out the paper-airplane data, ties every claim to a number and a reason, and answers an honest challenge without getting defensive. Mastery means your work persuades because the evidence is clear — not because you talked the loudest.
| Criterion | Not yet | Approaching | Mastered |
|---|---|---|---|
| Clear written report | Report is missing pieces — no question stated, or data and conclusion jumbled together. | Includes most parts, but the order is muddled or the method is too thin for a reader to follow. | Lays out the question, method, data, and conclusion plainly, so a reader can follow the whole investigation. |
| Visuals support the claim | Uses no table or graph, or picks one that does not fit the data. | Includes a graph but it is mislabeled, or it does not clearly connect to the point being made. | Chooses a table or graph that actually backs the claim — the right type, labeled, with the pattern easy to see. |
| Oral defense | Cannot explain the work aloud, or just reads the report back word for word. | Explains the gist but stumbles when asked to go past what is written down. | Explains the investigation aloud in their own words and answers questions about any part of it. |
| Claim–evidence–reasoning | States a conclusion with no data behind it, or lists data with no claim. | Connects a claim to data but skips the reasoning that links the two. | Ties every claim to specific data and to the reason that data supports it. |
| Responding to critique | Ignores a challenge, gets defensive, or swaps in whatever answer is suggested. | Hears the critique but cannot tell a fair point from an unfair one. | Handles a challenge to the results calmly and honestly — concedes a fair point, defends a sound one with evidence. |
| Integration (cross-domain) | Treats the skill as isolated; makes no connection to the year’s anchor. | Mentions the Semmelweis story but cannot say why his communication mattered as much as his data. | Connects clear communication to Semmelweis — he had the handwashing data but failed to persuade, and lives were lost — across History · Reading · Writing, and defends why it matters. |
“Here’s my claim: the wide-wing airplane flew farther. The evidence is this table — it averaged 4.2 meters against 3.1 for the narrow one. The reasoning is that more wing gave more lift, so it stayed up longer. And yes, one narrow throw went really far — probably a lucky gust — but I left it in the data anyway.”
“Um, the wide one is better. I have some numbers somewhere. I don’t really know how to explain why — it just went farther.”
You demonstrate this unit by presenting a finished investigation — a written report, a visual that backs it, and an out-loud defense — then fielding questions about it live, not on a multiple-choice test. A criterion counts as mastered only when a guide can watch you make the case: claim tied to evidence, evidence tied to a reason, and an honest answer when someone pushes back. Mastery is demonstrated, not awarded.
