Trust the Numbers? AI and Financial vs. Scientific Data
8–10 · Math / Science · 90 minutes
Kit: micro:bit + sample lesson plan — "Trust the Numbers? How AI Analyzes Financial and Scientific Data Differently" (grades 8-10, math/science). Students collect data, apply AI analysis, then examine how AI handles quantitative reasoning versus human analysts. Embedded AI literacy: AI as a tool that processes data but does not understand value — students learn the difference. Tailored to Charlotte's financial industry identity.
Without the PD, AI analysis is analysis. After: students collect data, run AI, and examine how AI handles quantitative reasoning vs. human analysts — and learn that AI processes numbers without understanding value, risk, or consequence. The Charlotte financial industry depends on that distinction.

What Students Do
Teams of 3+ collect a small dataset and analyze it for both numerical patterns and contextual meaning.
Don't standardize sensor placement across teams. Different microclimates make Phase 2 richer. Move between teams every 5 minutes; check that students are recording observations *and* numerical readings. The qualitative notes are the wedge they'll use to challenge AI in Phase 3.
Watch forTeams logging only numbers. Push them to write at least one observation per reading ("breeze picked up", "cloud passed over"). If the campus has visibly varied environments — shade vs. sun, paved vs. planted — push teams to spread out.
Teams query an AI tool to perform the same analysis. Compare AI output with the team's reasoning, paying particular attention to where AI handled the numbers but missed the meaning.
Frame the AI tool as a teammate, not an authority. When the AI prediction is wrong, students often default to "we'll fix our data." Interrupt that — the goal is to surface where AI and ground-truth diverge, not to reconcile.
Watch forTeams that find zero divergence. Either they're smoothing data unconsciously, or the AI is generic enough to match anything. Have them pick a single 5-minute window and compare in extreme detail.
Apply the verification protocol. Class produces a Charlotte-financial-industry-grade evidence base: AI processes numbers without understanding value, risk, or consequence.
The class trust guidelines are the deliverable. Push for specificity: not "AI is bad at humidity" but "AI underestimates humidity in conditions like ours when [specific local condition]." Local knowledge + data = the trust criteria.
Watch forGeneric statements ("AI is sometimes wrong"). Reject these gently — every guideline must reference a specific divergence the team observed.
A four-step verification protocol your teachers will build with us
A practice students learn once and apply to any AI output, in any subject, for the rest of their lives.
Where did the AI get its data? Is it the same data we used or generated?
How did the AI reach its conclusion? Can we follow the logic?
Does the output match what we observed with our own senses, instruments, or knowledge?
What might we have missed? What would we want a second opinion on?
More on the thinking behind this — the framework we built it from.
Materials
- micro:bit with sensors (included in kit)
- USB cables and student devices
- AI analysis tool access
- Financial-context scenario cards
- Comparison worksheet
Assessment
Each team produces a one-page artifact: their findings, the AI output they evaluated, and a written verdict on when this kind of AI work is worth trusting.
Evidence cites at least two cases where AI handled the math but missed the meaning, with the financial context for each.
For the Facilitator
Prior Knowledge Required
- Read and create simple data tables and bar/line graphs
- Distinguish between an observation (what we measured) and an inference (what we conclude)
- Familiarity with one-step variable assignment in block-based or text-based code
Exit Ticket
"Describe one moment today when your direct measurement told you something the AI missed. What did you measure, and what should the AI have done differently?"
Look for- Specific reference to a measurement (number + unit + location)
- Specific reference to what the AI output said
- A concrete claim about what the AI should have changed (input, comparison, caveat)
Anticipated Misconceptions
"If the AI says it, it must be right — it has access to all the data."
→ Show the AI a deliberately wrong dataset and have students predict the (wrong) output. Reinforce: AI confidence ≠ AI correctness. The AI processes whatever input it receives, including noise and bias.
"Our sensor data is wrong because it doesn't match the AI."
→ Have students re-measure with a second device or different location. Direct measurement is the ground truth — divergence with AI is a signal worth investigating, not an error to "fix."
"The AI is broken if it gives a different answer to the same question twice."
→ This is a feature, not a bug. Use it to discuss probabilistic vs. deterministic systems. Two valid outputs can describe the same data — students should learn to ask "what stayed the same?"
Differentiation
Pre-load the data table with column headers and one example row. Pair with a peer for the AI comparison phase. Provide a sentence frame for the evaluate phase: "We trust the AI when ___ because ___. We don't trust it when ___ because ___."
Standard procedure as written.
Add a fourth phase: students design a follow-up experiment that would resolve a specific AI-vs-observation disagreement they found. They write the protocol; they don't need to execute it in class.
Provide vocabulary cards in advance: sensor, prediction, observation, evidence, divergence. Allow team discussion in students' home language; final class artifacts can be authored bilingually. The verification protocol works in any language — emphasize that direct measurement and lived knowledge are the most authoritative inputs.
Slide Cues — 6 slides
- Collect real data on our campus
- Compare it with what an AI predicts
- Decide together when AI is worth trusting
- Source · Reasoning · Reality · Yourself
- You don't need to know how the AI works to check its work

Dear families, This week your student is learning a skill that will matter for the rest of their lives: how to decide when to trust an AI system. In this lesson, students used real sensors to measure conditions around our school and compared what they measured with what an AI predicted. The point is not that AI is bad — the point is that AI works best when paired with someone who knows the real situation. Your student is learning to be that someone. We call the protocol the verification protocol. It has four steps: check the source the AI used, check the reasoning, check the result against reality, and check yourself for what you might have missed. You can use this with your student at home — every time an AI assistant gives you an answer, ask: "How would we check this?"
