PSLE Science Reality Lab Vol No.581 | “Solar Wind Speed = 600 km/s” — Is Air Blowing Through Earth’s Atmosphere at 600 km/s?
A massive Primary 5/6 PSLE Science Reality Lab guide to reading real-time solar-wind speed as spacecraft plasma evidence, not ordinary atmospheric wind at Earth’s surface.
-
PSLE Science Reality Lab Vol No.580 | “Freezing Level = 3,000 m” — Is Everything Above That Height Frozen?
A massive Primary 5/6 PSLE Science Reality Lab guide to reading a freezing-level label as a 0°C air-temperature crossing, not a hard boundary where everything above is frozen.
-
PSLE Science Reality Lab Vol No.579 | “RONI = +0.8°C” — Is the Whole Tropical Pacific 0.8°C Warmer?
A massive Primary 5/6 PSLE Science Reality Lab guide to reading NOAA’s Relative Oceanic Niño Index as a defined three-month relative regional climate index, not a thermometer reading for the whole tropical Pacific.

Advanced Science Tutorials | 12-Week PSLE Science Revision Plan for Parents and Primary 6 Students
A structured 12-week PSLE Science revision plan covering diagnosis, active recall, application, open-ended questions, timed practice, error repair and final-week stabilisation.
-
PSLE Science Reality Lab Vol No.578 | “50.0 ± 0.5” — Is the True Value Guaranteed to Be Between 49.5 and 50.5?
A student-facing PSLE Science Reality Lab on how to interpret a measurement reported with expanded uncertainty without treating the plus-minus interval as an absolute wall outside which the measured quantity cannot lie.
-
PSLE Science Reality Lab Vol No.577 | “Bootstrap Support = 95” — Is That a 95% Chance the Branch Is True?
A student-facing PSLE Science Reality Lab on how to read bootstrap support on a phylogenetic tree without turning a resampling support value into a literal probability that one evolutionary branch is true.
