PSLE Science Reality Lab Vol No.576 | “Volcanic Ash Polygon” — Is Ash Present Everywhere Inside the Shape?
A student-facing PSLE Science Reality Lab on how to read volcanic-ash advisory polygons without treating a forecast or observed ash area as a direct measurement of ash at every point inside it.
-
PSLE Science Reality Lab Vol No.575 | “This Soil Map Polygon Is Labelled Loam” — Is Every Spot Inside It the Same Soil?
A student-facing PSLE Science Reality Lab on how to read soil-survey polygons without treating a map-unit label as proof that every point inside the boundary has identical soil.
-
PSLE Science Reality Lab Vol No.574 | “This Electron Micrograph Is Blue and Green” — Were the Cells Really Those Colours?
A massive student-facing PSLE Science evidence guide to reading colourised electron micrographs without mistaking added, encoded or overlaid colours for the specimen’s natural visible colour.
-
PSLE Science Reality Lab Vol No.573 | “34-kt Wind Radius = 150 nm NE” — Does Every Place Within 150 nm Have 34-kt Winds?
A massive student-facing PSLE Science evidence guide to reading tropical-cyclone wind radii as quadrant-based maximum extents rather than a uniform circular wind field.
-
PSLE Science Reality Lab Vol No.572 | “This Star Has Eight Bright Spikes” — Are Those Real Beams Shooting From the Star?
A massive student-facing PSLE Science evidence guide to deciding whether bright spikes in a Webb telescope image belong to the star or to the telescope’s imaging system.
-
PSLE Science Reality Lab Vol No.571 | “The Air-Quality Map Is Orange Here” — Was AQI Measured at Every Point in the Orange Area?
A massive student-facing PSLE Science evidence guide to reading coloured air-quality contours as approximate spatial representations rather than direct measurements at every point.
