PSLE Science Reality Lab Vol No.295 | “Sensor Sensitivity = 20 mV/°C” — Is the Sensor 20% Accurate?
A massive Primary 5/6 PSLE Science Reality Lab guide on reading sensor sensitivity correctly: why mV/°C describes how output changes with the measured quantity, not a percentage accuracy claim.
-
PSLE Science Reality Lab Vol No.294 | “First Image of a Black Hole” — Was This One Ordinary Camera Photograph?
A massive PSLE Science Reality Lab guide for Primary 5/6 learners on the Event Horizon Telescope: how real radio measurements become a reconstructed black-hole image without being an ordinary single-camera photograph.
-
PSLE Science Reality Lab Vol No.293 | “UPF 50” — Does the Fabric Block Only 50% of UV?
A massive PSLE Science Reality Lab guide for Primary 5/6 learners on reading UPF 50 clothing labels as protection factors rather than percentages, while checking test conditions and coverage.
-
PSLE Science Reality Lab Vol No.292 | “100 W Equivalent” — Does This LED Use 100 Watts?
A massive PSLE Science Reality Lab guide for Primary 5/6 learners on reading “100 W equivalent” LED packaging without confusing brightness equivalence, lumens and actual electrical power.
-
PSLE Science Reality Lab Vol No.291 | “Listen to the Black Hole” — Did a Microphone Record This Sound in Space?
A massive PSLE Science Reality Lab guide for Primary 5/6 learners on data sonification: how to separate measured scientific data, mapping rules and generated audio without mistaking a representation for a microphone recording.
-
PSLE Science Reality Lab Vol No.290 | “River Gauge = 3.0 m” — Is the River 3 m Deep?
A massive PSLE Science Reality Lab guide for Primary 5/6 learners on reading river stage or gage height without mistaking a datum-based water-level measurement for river depth or streamflow.
