Hands-on

Interactive AI labs

Browser-based, deterministic labs designed for classrooms. Results can save to a student account for mastery tracking.

Representation & Reasoning

Decision Tree Builder

Build yes/no rule maps that classify situations — the foundation of rule-based reasoning.

Min band: K2

Machine Learning

Train a Classifier

Label examples, train a simple model, and read accuracy plus confusion counts.

Min band: G35

Ethical Design

Bias Explorer

Swap training distributions and watch fairness and accuracy metrics move.

Min band: G35

Machine Learning

Perception Lab

See how sensors capture signals and features differ from full understanding.

Min band: G35

Humans & AI

Prompt & Evidence

Practice verification: claim → evidence → confidence for generative outputs.

Min band: G68

Societal Impact

Recommender Toy

Adjust user histories and observe ranking feedback loops.

Min band: G68

Ethical Design

Model Card Writer

Document purpose, data, metrics, limits, and ethical notes for a system.

Min band: G35

Machine Learning

Neural Net Sandbox Lite

Toy network intuition: capacity, noise, and overfitting (HS/college).

Min band: G912

Humans & AI

Hallucination Hunter

Classify AI outputs as supported, false, or unverifiable — and learn the tells of invented confidence.

Min band: G68

Humans & AI

Prompt Architect

Build professional prompts: goal, constraints, format, critique loop, and refuse line.

Min band: G68

Societal Impact

Privacy Trail

Rate real-world sharing scenarios and practice safer data hygiene with AI tools.

Min band: G68

Ethical Design

System Tradeoff Studio

Set thresholds under uncertainty: false alarms vs missed harm, trust vs safety theater.

Min band: G912

Humans & AI

MCP Protocol Studio

Design tools, resources, and auth boundaries for a Model Context Protocol server — the FDE integration surface.

Min band: FDE

Machine Learning

Agent Orchestration Lab

Wire cheap→expensive model cascades with deterministic escalation gates and cost budgets.

Min band: FDE

Societal Impact

Customer Engagement Loop

Run the FDE loop: ambiguous brief → scope → prototype plan → eval criteria → handoff memo.
