Education. Roof weather station; Seismograph; Campus 5G; Classroom air
Education · Sector explainer
Explainer
A weather station on the gym roof, a seismograph in the basement, a CO₂ sensor on the classroom wall, a statewide network run by the university down the road. Each chapter puts one education deployment on the stage, lets you change the input that matters and computes what a student would.
01 · University mesonet
Spatial density
A state or provincial mesonet run by a university puts identical towers across the territory so that every town is close to a reading. On a square layout the spacing is √(A/n), and the average distance from any point to its nearest station is about 0.383 times the spacing, the mean distance from a random point in a square to its centre. Set the area and the number of towers.
02 · School weather station
Psychrometry
A weather station on the school roof gives the class real numbers and gives the coach a call. The heat index combines temperature and humidity into how hot it feels in shade; this is the US National Weather Service algorithm, the Rothfusz regression with its low- and high-humidity adjustments, and its caution bands. Dew point from the Magnus formula.
03 · School seismograph
Seismology
A seismograph in the school basement records the P wave first and the slower S wave after it. The gap between them grows with distance: d = Δt · Vp·Vs/(Vp − Vs). With typical crustal speeds of about 6 km/s for P and 3.5 km/s for S, that is roughly 8 km for every second of S − P, the rule students use on their own records. Three schools with three distances locate the quake. Set the S − P time read off the trace.
04 · Classroom air
Mass balance
A CO₂ sensor on the classroom wall turns ventilation into a number the class can see. At steady state the room sits above outdoor air by the generation rate over the airflow: ΔC = G/Q, with G = 0.0052 L/s per seated adult (children breathe out less, so this errs high) and outdoor air at 420 ppm. The room approaches that level with time constant V/Q. Health Canada’s long-term exposure limit for indoor CO₂ is 1,000 ppm.
05 · Campus private 5G
Link budget
A campus network on shared mid-band spectrum, used for teaching and for research on the network itself. Free-space loss is 20 log d + 20 log f + 32.44 (d in km, f in MHz); buildings, trees and bodies add clutter loss on top. What the link budget leaves sets the cell radius, and hexagonal cells of radius r each cover 2.6 r². Set the band, the budget and the clutter.

Data literacy
What a school board asks to see, from the sector research. The data-literacy case is arithmetic: a station that reports every few minutes gives each class a full year of real, local records to plot, average and question.
Reporting interval
School stations, university networks and campus testbeds, installed safely, kept running and wired to the classroom.
