PSLE Science Reality Lab Vol No.404 | “Magnitude 6.1, Then 5.8” — Did the Earthquake Become Smaller After It Happened?
A massive Primary 5/6 evidence guide to revised earthquake magnitudes: why the physical event stays in the past while the scientific estimate can improve as more seismic data and analysis become available.

PSLE Science Reality Lab Vol No.403 | “Brightness Temperature = −43°C” — Did a Thermometer in the Cloud Measure −43°C?
A massive Primary 5/6 evidence guide to brightness temperature: why a satellite radiometer can report a temperature-like value without directly placing a thermometer in a cloud, surface or air layer.

PSLE Science Reality Lab Vol No.402 | “Sound Power Level = 90 dB” — Will a Sound Meter Read 90 dB Wherever You Stand?
A massive Primary 5/6 evidence guide to acoustic specifications: why sound-power level characterises a source while sound-pressure level depends on measurement position, distance and environment.
-
PSLE Science Reality Lab Vol No.401 | “Gas Flow = 10 Standard L/min” — Are Exactly 10 Litres Passing Each Minute at the Actual Temperature and Pressure?
A massive Primary 5/6 evidence guide to standard gas flow: why standard L/min expresses gas amount on stated reference conditions rather than necessarily the physical volume moving through a line each minute.

PSLE Science Reality Lab Vol No.400 | “Battery Nominal Voltage = 3.6 V” — Is the Cell Always at 3.6 V?
A massive Primary 5/6 evidence guide to nominal battery voltage: why a 3.6 V label is a representative specification rather than an exact voltage fixed at every instant.
-
PSLE Science Reality Lab Vol No.399 | “2× Vertical Exaggeration” — Are the Slopes Really Twice as Steep?
A massive Primary 5/6 evidence guide to vertical exaggeration: why stretched terrain relief can make slopes look steeper without changing the real elevations, distances or physical landscape.
