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.
-
PSLE Science Reality Lab Vol No.065 | “Open Data Available” — Does That Mean the Result Has Already Been Reproduced?
A massive Primary 5/6 Reality Lab guide to open scientific data: why making data available improves transparency, what another person can actually check, and why rerunning the same data is not the same as collecting new evidence.
-
PSLE Science Reality Lab Vol No.064 | “The Data Were Adjusted” — What Was Changed, and Why?
A massive Primary 5/6 Reality Lab guide to adjusted scientific data: why measurements may be corrected for known non-target shifts, how raw and adjusted records differ, and what evidence makes an adjustment trustworthy.
