PSLE Science Reality Lab Vol No.564 | “Tsunami Warning” — Does That Mean a Destructive Wave Has Already Been Observed?
A student-facing PSLE Science evidence guide to reading an official tsunami warning as a time-sensitive scientific communication object without confusing an early hazard alert with proof that a destructive wave has already been observed everywhere.

PSLE Science Reality Lab Vol No.563 | “Cloud Mask: Confident Clear” — Does That Prove the Pixel Was Completely Cloud-Free?
A student-facing PSLE Science evidence guide to reading satellite cloud-mask confidence labels without turning an algorithmic classification into proof that a pixel was perfectly cloud-free.
-
PSLE Science Reality Lab Vol No.562 | “Lake Residence Time = 10 Years” — Does Every Water Molecule Stay for Ten Years?
A massive Primary 5/6 PSLE Science evidence guide to reading “lake residence time = 10 years” without mistaking a system-level renewal or mean transport timescale for the exact stay of every water molecule.
-
PSLE Science Reality Lab Vol No.561 | “This Bond Line Is Twice as Long in the Molecule Drawing” — Is the Real Bond Twice as Long?
A massive Primary 5/6 PSLE Science evidence guide to reading a 2D chemical structure diagram without mistaking the drawn length of a bond line for a literal scale measurement of molecular distance.
-
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.
