PSLE Science Reality Lab Vol No.385 | “40% Chance of Above-Normal Rainfall” — Does That Mean 40% More Rain?
A Primary 5/6 evidence guide to reading a seasonal climate outlook without confusing the probability of an above-normal rainfall category with 40% more rain.
-
PSLE Science Reality Lab Vol No.384 | “1 m DEM” — Are the Elevation Values Accurate to 1 m?
A Primary 5/6 evidence guide to reading a digital elevation model label without confusing 1 m grid-cell size with 1 m vertical elevation accuracy.
-
PSLE Science Reality Lab Vol No.383 | “Storm-Surge Map Says 6 ft” — Is 6 ft the Exact Flood Depth That Will Happen There?
A Primary 5/6 evidence guide to reading a storm-surge inundation map without turning a reasonable worst-case preparation value into an exact flood-depth prediction.
-
PSLE Science Reality Lab Vol No.382 | “The Probe Says 40°C” — Could the Act of Measuring Have Changed the Temperature?
PSLE Science Reality Lab: learn how a measuring device can disturb the system it measures, why a displayed temperature may describe the probe-sample interaction rather than the undisturbed sample, and how to test for measurement loading.
-
PSLE Science Reality Lab Vol No.381 | “As Found: Out of Tolerance; As Left: In Tolerance” — Which State Describes the Measurements Made Before Calibration?
PSLE Science Reality Lab: learn how to read “as found” and “as left” calibration information, why a repaired instrument does not automatically repair old measurements, and how to evaluate earlier data without overclaiming.
-
PSLE Science Reality Lab Vol No.380 | “Dead Band = 0.2 Units” — Can the Measured Quantity Change While the Display Stays the Same?
PSLE Science Reality Lab: learn why an unchanged display does not always prove an unchanged quantity, how dead band differs from accuracy and resolution, and what evidence can reveal hidden small changes.
