PSLE Science Reality Lab Vol No.172 | “95th Percentile = 42” — Were 95% of the Readings Exactly 42?
A Primary 5/6 PSLE Science Reality Lab guide to percentile values in scientific monitoring reports: learn why a 95th percentile of 42 is a ranked threshold, not a claim that 95% of readings equal 42.

PSLE Science Reality Lab Vol No.171 | “Turbidity = 20 NTU” — Does That Mean There Are 20 Particles in the Water?
A Primary 5/6 PSLE Science Reality Lab guide to turbidity: learn why 20 NTU is an optical light-scattering result, not 20 particles, and how to keep water-quality claims inside the evidence.

PSLE Science Reality Lab Vol No.171 | “These Data Are Provisional” — Does That Mean They Are Wrong?
A Primary 5/6 PSLE Science Reality Lab guide to provisional scientific data: learn why timely observations can be useful before final review without being treated as either wrong or final.
-
PSLE Science Reality Lab Vol No.170 | “Data Completeness = 95%” — Does That Mean the Measurements Are 95% Accurate?
A Primary 5/6 PSLE Science Reality Lab guide to data-completeness claims: learn why 95% complete means most expected observations are present, not that the measurements are 95% accurate.
-
PSLE Science Reality Lab Vol No.170 | “Relative Humidity = 80%” — Is 80% of the Air Water?
A Primary 5/6 PSLE Science Reality Lab guide to relative humidity: learn why 80% RH is not 80% water, how temperature changes the percentage, and what a weather display really supports.

PSLE Science Reality Lab Vol No.169 | “Wind Gust = 70 km/h” — Was the Wind Blowing at 70 km/h the Whole Time?
A Primary 5/6 evidence guide to wind reports: learn why a gust is a short peak or rapid fluctuation, not proof that the wind stayed at that speed for the whole observation period.
