AI in the Real World: Intelligent Systems in Our Community
7–9 · Science / Technology · 90 minutes
Kit: micro:bit + sample lesson plan — "AI in the Real World: How Your Community Uses Intelligent Systems" (grades 7-9, science/technology). Students investigate AI applications in industries along the Columbus tech corridor, then build a simple classification system using micro:bit data. Embedded AI literacy: students evaluate AI decision-making in contexts their families work in daily.
Without the PD, AI applications in tech-corridor industries would be a career-day topic. After: students build a working classification system themselves and evaluate AI decision-making in contexts their families navigate every workday.

Content Objectives
- Connect classroom data investigation to real-world industry applications

AI Literacy Objectives
- Identify how AI classification systems work in industries familiar to the community
- Apply structured verification practice to industry AI decisions
- Articulate trade-offs between rule-based and learned classification
What Students Do
Teams choose an industry along the Columbus tech corridor (insurance, healthcare, logistics, finance) and identify a real AI application in that field. Use micro:bit data to simulate a small classification problem the industry might face.
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.
Each team builds a simple classification rule using their sensor data (e.g., "if temperature > X and motion = Y, classify as Z"). Test the rule against new data; record errors.
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 structured verification practice to AI decision-making in their chosen industry context. Compare a rule-based human classifier with an AI classifier — which is more transparent? Which is more accurate? Which would families in tech-corridor jobs trust?
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 tool access (chosen by each team)
- Industry/career application cards (Columbus tech corridor sectors)
- Data recording sheet and chart paper
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.
Final evaluation cites a specific industry, a specific classification problem, and a defensible position on rule vs. AI for that case.
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

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?"
