PSLE Science Reality Lab Vol No.493 | “Lightning Count = 100” — Were There 100 Separate Flashes?
A massive Primary 5/6 PSLE Science Reality Lab guide to lightning-count evidence: learn why events, groups and flashes are different counting objects, how satellite detection rules create the reported number, and how to test claims before treating one count as 100 separate lightning flashes.

PSLE Science Reality Lab Vol No.492 | “The Funnel Plot Looks Asymmetrical” — Does That Prove Studies Were Hidden?
A massive Primary 5/6 PSLE Science Reality Lab guide to funnel plots: learn why asymmetry can signal a small-study pattern without proving hidden studies or publication bias, and how to test alternative explanations with scientific evidence.
-
PSLE Science Reality Lab Vol No.491 | “This Wind Streamline Curves Here” — Did One Air Parcel Follow That Exact Path?
A massive Primary 5/6 PSLE Science Reality Lab guide to reading wind streamline maps: learn why an instantaneous streamline is not automatically the trajectory of one air parcel, how animation can mislead, and what evidence is needed before turning a flow field into a path claim.

PSLE Science Reality Lab Vol No.490 | “Warm-Up Time = 30 min” — Can We Trust the Reading Immediately After Switch-On?
A massive Primary 5/6 PSLE Science Reality Lab guide to instrument warm-up: learn why a steady display immediately after switch-on may not mean stable measurement performance, and why warm-up is a test condition rather than a guarantee of perfect accuracy.
-
PSLE Science Reality Lab Vol No.486 | “MPN = 100 per 100 mL” — Were Exactly 100 Microorganisms Counted?
A Primary 5/6 evidence guide to Most Probable Number: how positive/negative test patterns produce a statistical concentration estimate rather than an exact direct microorganism count.
