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.
-
PSLE Science Reality Lab Vol No.398 | “Pan-Sharpened to 15 m” — Were All the Colour Bands Measured at 15 m?
A massive Primary 5/6 evidence guide to pan-sharpening: how finer panchromatic spatial detail can be fused with coarser multispectral colour information without making every colour band a native 15 m measurement.

PSLE Science Reality Lab Vol No.397 | “The Trip Blank Contained Benzene” — Does That Prove the River Sample Contained Benzene?
A massive Primary 5/6 evidence guide to trip blanks: why a positive travelling control signals possible contamination without acting as a second environmental sample.
