PSLE Science Reality Lab Vol No.516 | “This LiDAR Intensity Patch Is Bright” — Is the Ground Higher or Naturally Brighter?
A massive Primary 5/6 PSLE Science Reality Lab guide to LiDAR intensity: why a bright grayscale patch represents stronger recorded laser return, not automatically higher ground or ordinary visible brightness.
-
PSLE Science Reality Lab Vol No.515 | “This Seafloor Patch Is Bright on the Sonar Map” — Is It Shallower Water?
A massive Primary 5/6 PSLE Science Reality Lab guide to sonar backscatter: why a bright seafloor patch can mean stronger returned sound rather than shallower water.
-
PSLE Science Reality Lab Vol No.514 | “The Cloud Is Directly Above This Spot” — Could Satellite Parallax Shift Its Apparent Position?
A massive Primary 5/6 PSLE Science Reality Lab guide to satellite parallax: why a tall cloud or plume can appear shifted from its true ground position in an angled satellite view.
-
PSLE Science Reality Lab Vol No.513 | “This Water Is Brilliantly Bright in the Satellite Image” — Is Something Bright Floating on the Surface?
A massive Primary 5/6 PSLE Science Reality Lab guide to sunglint: why brilliant water in satellite imagery can come from Sun–surface–sensor geometry rather than bright material floating on the water.

PSLE Science Reality Lab Vol No.510 | “Composite Reflectivity = 55 dBZ” — Was 55 dBZ Measured at the Same Height Everywhere?
A massive Primary 5/6 PSLE Science Reality Lab guide to composite weather-radar reflectivity: why a 55 dBZ map value may be the maximum from different heights, not one common-altitude or direct ground-rain measurement.

PSLE Science Reality Lab Vol No.509 | “Pressure = 2000 dbar” — Is the Argo Float Exactly 2000 m Deep?
A massive Primary 5/6 PSLE Science Reality Lab guide to Argo ocean profiles: why 2000 dbar is sea pressure, not automatically an exact depth of 2000 metres, and how to evaluate units, conversion, quality flags and evidence boundaries.
