PSLE Science Reality Lab Vol No.558 | “Depth to Water = 12 m” — Is the Aquifer Only 12 m Deep?
A massive Primary 5/6 PSLE Science evidence guide to groundwater well records: why “depth to water” is the distance to a water level, not the aquifer’s total depth, thickness or stored water.
-

PSLE Science Reality Lab Vol No.557 | “Genome Assembly N50 = 1 Mb” — Is the Genome 50% Accurate or Complete?
A massive Primary 5/6 PSLE Science evidence guide to genome-assembly N50: how to read a contiguity statistic without turning 50 into a percentage accuracy, completeness or correctness score.
-

PSLE Science Reality Lab Vol No.556 | “Human Reference Genome” — Is This the DNA Sequence of One Average Person?
A massive Primary 5/6 PSLE Science evidence guide to the human reference genome: why a reference sequence is a comparison framework, not one average, normal or ideal person’s DNA.
-

PSLE Science Reality Lab Vol No.555 | “The Satellite Map Shows Rainbow Rings” — Did the Ground Form Real Coloured Bands?
A massive Primary 5/6 PSLE Science evidence guide to InSAR interferograms: how repeating colour fringes encode relative satellite-to-ground displacement without becoming literal coloured rings on the ground.
-

PSLE Science Reality Lab Vol No.554 | “The Arrow Is Longer” — Does That Mean the Flow Is Faster?
A massive Primary 5/6 PSLE Science evidence guide to vector-field maps: why arrow length is not automatically speed, and how legends define whether direction, colour, length or classes encode a scientific quantity.

PSLE Science Reality Lab Vol No.553 | “Thermostat Set to 22°C” — Is the Whole Room Exactly 22°C?
A massive Primary 5/6 PSLE Science evidence guide to thermostat displays: how to separate a temperature setpoint from a sensor reading and from temperatures throughout a real room.
