A massive Primary 5/6 PSLE Science Reality Lab guide to solar-flare classes: learn why X2 is ten times M2 on the classification-flux scale, how A/B/C/M/X letter steps and numeric multipliers work, and why flare class does not determine every Earth effect.

PSLE Science Reality Lab Vol No.481 | “Earthquake Beachball” — Is the Black-and-White Circle a Map of the Fault on the Ground?

—

by

A massive Primary 5/6 PSLE Science Reality Lab guide to earthquake focal-mechanism beachballs: learn why the black-and-white circle is a scientific projection, not a ground map or fault footprint, and why two nodal planes require independent evidence.

PSLE Science Reality Lab Vol No.480 | “This Area Is Jurassic” — Did Every Rock Here Form at the Same Exact Time?

—

by

A massive Primary 5/6 PSLE Science Reality Lab guide to geologic maps: learn why a unit labelled Jurassic does not mean every rock formed at one exact time, and how age ranges, legends, contacts, sampling and map scale control the claim.

PSLE Science Reality Lab Vol No.479 | “Preserved Specimen Record: 1924” — Does That Mean the Species Still Lives There Today?

—

by

A massive Primary 5/6 PSLE Science Reality Lab guide to preserved-specimen biodiversity records: learn why an old specimen can prove historical occurrence without proving a species still lives there today, and how eventDate, basisOfRecord and current evidence control the claim.

PSLE Science Reality Lab Vol No.478 | “Earthquake Depth = 10 km” — Was It Really Measured Exactly 10 km Deep?

—

by

A massive Primary 5/6 PSLE Science Reality Lab guide to earthquake depth reports: learn why 10 km can be a fixed solution depth rather than an exact measurement, and how metadata, uncertainty and review status control the claim.
