A classroom investigation platform lets Brazilian high-school students measure noise, heat, and air at their own school, then use the results to propose a concrete change.

Field notes

The site organizes classroom inquiry as a repeatable measurement workflow rather than a worksheet: groups collect readings, inspect variation and outliers, write from the resulting calculations, and record a proposed intervention. Its examples include a noise study comparing front and back rows and a heat study comparing concrete with tree-shaded areas. The homepage says a phone, ordinary thermometer, measuring tape, or manual entry is sufficient, with offline readings uploaded when connectivity returns.
