PSLE Science Reality Lab Vol No.560 | “These Two Species Sit Next to Each Other at the Tips” — Are They the Closest Relatives?
A massive Primary 5/6 PSLE Science evidence guide to reading phylogenetic trees without mistaking page position or neighbouring tips for the closest evolutionary relationship.
-
PSLE Science Reality Lab Vol No.559 | “Peak Wave Period = 8 s” — Did Every Wave Arrive Exactly Eight Seconds Apart?
A massive Primary 5/6 PSLE Science evidence guide to reading a marine buoy or forecast label such as “peak wave period = 8 s” without mistaking one spectral summary for the timing of every individual wave.

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.
