PSLE Science Reality Lab Vol No.071 | “Tested for 10,000 Cycles” — Does an Accelerated Test Prove Years of Normal Use?
A Primary 5/6 Reality Lab guide to accelerated durability claims: how to separate test cycles from ordinary-use lifetime, inspect added stresses, compare failure modes and decide how far a laboratory result can travel.
-
PSLE Science Reality Lab Vol No.070 | “Three Sensors Agree” — Can They All Share the Same Bias?
A Primary 5/6 Reality Lab guide to a subtle evidence trap: several sensors can agree closely and still share the same measurement bias. Learn how to check agreement, references, calibration and shared conditions before treating consensus as correctness.

PSLE Science Reality Lab Vol No.069 | “This Time-Lapse Shows Fast Change” — Did the Video Speed Change the Apparent Rate?
A massive Primary 5/6 Reality Lab guide to time-lapse evidence: how to separate real elapsed time, frame interval and playback duration so a sped-up scientific video does not become a false claim about how quickly the process happened.
-
PSLE Science Reality Lab Vol No.068 | “The Result Is Robust” — Did It Survive Other Reasonable Ways of Analysing the Same Data?
A massive Primary 5/6 Reality Lab guide to robustness claims: how to ask whether a scientific conclusion survives other reasonable ways of analysing the same data, without confusing robustness with reproducibility or independent replication.
-
PSLE Science Reality Lab Vol No.067 | “Within Tolerance” — Does Passing the Limit Mean the Measurement Is Exactly on Target?
A massive Primary 5/6 Reality Lab guide to tolerance claims: how to separate a target value, an allowed range, a measured result and measurement uncertainty without mistaking “within tolerance” for “exactly correct”.
-
PSLE Science Reality Lab Vol No.066 | “This Image Was Enhanced” — Did Processing Reveal a Feature or Create an Artifact?
A massive Primary 5/6 Reality Lab guide to processed scientific images: how enhancement can reveal faint real features, how processing can also create misleading artifacts, and how to check what the underlying observations truly support.
