Learning Objectives
- Describe how sensors convert physical signals into data.
- Prototype a sensor-based solution for a school or neighborhood challenge.
- Compare unplugged models with real microcontrollers (optional).
Sensor Quest
Students investigate how environmental sensors capture inputs and outputs through unplugged props or optional micro:bit kits.
Lesson Overview

Session Breakdown
Core Session
Sensor Scavenger Hunt
Teams explore stations (light, sound, air quality, movement) to identify real-world sensors and map input/output flows.
- Mini-lesson: sensor vocab + civic examples
- Activity: station rotations with observation cards
- Share-out: match sensors to community needs
Extension
Build & Pitch
Optional micro:bit or cardboard-prop build where students pitch a sensor concept and storyboard how data helps solve a challenge.
- Rapid prototyping + peer feedback loop
- Reflection: ethics + data stewardship
- Optional share with local partner
Materials & Prep
Stations
Sensor Cards
Printable cards describing the sense, signal, and sample civic use.
Laminate for reuse if possible
Optional Tech
Micro:bit Kits
Simple scripts for light, sound, and accelerometer demos.
Includes unplugged alternatives
Teacher Prep
Facilitator Script
Station timing guide, safety reminders, and discussion prompts.
Approx. 15 min prep
Assessment & Reflection
Artifacts
- Sensor pathway diagrams (input → process → output).
- Pitch cards describing the challenge, sensor idea, and impact.
- Exit tickets capturing one question about sensing data.
Extensions
- Invite STEM mentors to demo real instrumentation.
- Host a "sensor fair" where students present prototypes.
- Connect to science fair or community showcase.
