The MET & TeddyField Guides.Measurement through real-world adventure.
Ten themed volumes that turn measurement science into something students can see, touch, and care about — from the basketball court to the factory floor to the launch pad.

Measurement science through topics students already love.
The MET and Teddy Field Guide Series is a collection of ten themed volumes that present measurement concepts through real-world topics students already care about. Sports. Food and Cooking. Nature and Agriculture. Healthcare. Aerospace. Transportation. Manufacturing. Measurement Tools. Science Projects. Even Jokes.
Each volume is built on a single principle: measurement is everywhere, and once you start seeing it, you can’t stop. A regulation basketball must be inflated to 7.5–8.5 psi. The GPS guiding a spacecraft must be accurate to fractions of a meter. A pharmaceutical tablet’s mass tolerance is measured in milligrams. These aren’t trivia — they’re invitations to explore the science that holds the world together.
Every Field Guide volume includes MET and Teddy dialogues that bring concepts to life through character-driven conversation, Teddy Moments where Teddy’s curiosity opens new measurement doors, and glossaries sourced from VIM and GUM definitions — adapted into age-appropriate language for each certification level.
The result: a student who picks up the Aerospace Field Guide because they dream of space walks away understanding why precision matters at 25,000 mph, what measurement traceability means, and how calibration keeps astronauts alive.

Every fact, definition, and activity in the Field Guide Series is sourced from the MET Field Guide — the curated RAG knowledge base verified against ISO 17025, NIST GUM, VIM, and internationally recognized standards.
Three elements. Every Field Guide.
Each volume follows the same proven structure — blending character-driven narrative, interactive moments, and standards-sourced reference into a cohesive experience.
Ten volumes. One universe.
Each Field Guide connects a world students love to the measurement science hidden inside it.
Basketball inflation pressure, sprint timing accuracy, goal-line technology — measurement keeps every sport fair, safe, and thrilling.
Why 1/4 tsp vs 1/2 tsp changes everything. Temperature, mass, volume, time — the kitchen is a measurement laboratory hiding in plain sight.
Soil pH, rainfall gauges, crop yield measurement, pollination tracking — nature and farming are the original measurement laboratories.
Thermometers, blood pressure cuffs, dosage calculations, X-ray calibration — healthcare measurements are literally life-or-death.
Rocket thrust tolerances, orbital trajectory calculations, satellite positioning, atmospheric reentry angles — where a fraction of a degree changes everything.
Speedometer calibration, tire pressure monitoring, GPS navigation accuracy, bridge load tolerances — every journey depends on trusted measurements.
Dimensional tolerances, statistical process control, gauge R&R, quality inspection — how factories ensure every part fits and every product works.
Rulers, calipers, micrometers, scales, thermometers, multimeters — the tools themselves, how they work, and why resolution matters.
Pendulums, density towers, parallax experiments, bridge loading — real projects with real data that teach repeatability and uncertainty through doing.
Measurement puns, Teddy-based physical comedy, caliper wordplay, and uncertainty humor — the best-calibrated teaching tool there is.
MET and Teddy in the Aerospace Field Guide.
Here’s what it looks like when a student opens a Field Guide and asks a question. MET explains. Teddy reacts. Science happens.

Every topic hides a
measurement story.
Ten volumes. From the kitchen table to the launch pad to the factory floor. Hundreds of real-world measurement facts, MET and Teddy dialogues, Teddy Moments, and standards-sourced glossaries. Two Field Guides who make the science feel like an adventure worth taking.
