A massive Primary 5/6 PSLE Science Reality Lab guide to fault-map symbols: learn why dashed, dotted or queried traces can communicate approximate, inferred or concealed locations rather than a fault disappearing, and why the legend controls the meaning.

PSLE Science Reality Lab Vol No.483 | “IP67” — Does That Mean a Device Is Waterproof at Any Depth for Any Length of Time?

—

by

A Primary 5/6 evidence guide to reading IP67 as a defined ingress-protection classification rather than an unlimited waterproofing promise.

PSLE Science Reality Lab Vol No.487 | “Species Distribution Map” — Does the Shaded Area Mean the Species Lives Everywhere Inside It?

—

by

A massive Primary 5/6 PSLE Science Reality Lab guide to species distribution maps: learn why a shaded range polygon is not proof that a species occupies every point inside it, and how to check map type, date, presence, origin, seasonality and supporting evidence.

PSLE Science Reality Lab Vol No.482 | “Solar Flare X2” — Is It Just Two Units Stronger Than M2?

—

by

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.
