Communicate Findings with Models

A finding nobody understands is a finding nobody can use. After scientists and engineers run an experiment, they have to share what they learned. They do that with models — physical objects, diagrams, graphs, simulations, and short written summaries. The right model turns raw data into a story the audience can follow. In this lesson you will pick a model, build it, and write a tight summary using the CER frame: Claim, Evidence, Reasoning.

The five main ways to share findings

• Physical model: a hands-on object built to scale. Good for shape, size, and how parts fit together. Example: a cardboard solar system.
• Schematic diagram: a labeled drawing of parts. Good for circuits, machines, body systems. Lines and labels matter more than looking pretty.
• Graph: numbers turned into a picture. Bar graph for categories, line graph for change over time, pie chart for parts of a whole.
• Infographic: one main idea with a few visuals and short text. Good for the public — at a glance, not for detail.
• Written summary: a paragraph using the CER frame. Always include this with any visual model.

Audience first

Before you choose a model, ask who is reading. A peer scientist wants the data table, the error bars, and the technical words. A friend or parent wants a clear picture, plain words, and one main idea. Same finding, different model. Pick the lowest-effort version your audience needs to understand the result.

Scale and labels

• Scale tells the reader how big the model is compared to the real thing. A scale of 1 cm = 1 m means every centimeter stands for one meter.
• Labels name every part. A diagram without labels is just a picture. Use short, accurate words.
• A title and a legend let a stranger read your model without you standing there to explain it.
• Units belong on every axis and every measurement: cm, s, deg C, kg.

The CER frame for a written summary

1. Claim: one sentence that answers the question. Example: The plant grows fastest in direct sunlight.
2. Evidence: the numbers and observations that support the claim. Example: Over 7 days the sun plant grew 4 cm; the shade plant grew 1 cm.
3. Reasoning: the science that links evidence to claim. Example: Sunlight powers photosynthesis, so more light means faster growth.

Honest models

A model can lie without meaning to. A graph that starts the y-axis at 80 makes a tiny gain look huge. A diagram missing the failed trial hides the truth. Honest communication shows the real numbers, the units, and the parts that did not work, not just the parts that did. If the audience cannot trust your model, the finding is wasted.
