PSLE Science Reality Lab Vol No.527 | “The Change Map Shows a Red Edge” — Did the Ground Really Change, or Were the Images Slightly Misaligned?
A Primary 5/6 evidence guide to scientific change maps: how tiny image misalignment can create false red-and-blue edges that look like real physical change.
-
PSLE Science Reality Lab Vol No.526 | “The Line Connects the Measurements” — Was the Value Measured at Every Moment Between the Dots?
A Primary 5/6 evidence guide to connected scientific measurements: how to separate observed dots from interpolated, smoothed or modelled values between them.
-
PSLE Science Reality Lab Vol No.525 | “Result Above Calibration Range” — Can We Trust the Exact Concentration?
A Primary 5/6 evidence guide to results above a laboratory calibration range: why extrapolated exact concentrations need method support and why dilution and reanalysis can restore valid quantitation.
-
PSLE Science Reality Lab Vol No.524 | “This Scatter Plot Shows 80 Visible Dots” — Were There Only 80 Measurements?
A Primary 5/6 evidence guide to scatter-plot overplotting: why visible dots can undercount measurements when records overlap, and how transparency, jitter and raw counts change what the graph shows.

Top 10 Debugging Skills Worth Learning
Learn 10 durable debugging skills: reproduce failures, compare expected and actual behaviour, locate the earliest divergence, reduce failing cases, test competing causes, trace intermediate state, apply minimal fixes and run regression checks.

PSLE Science Reality Lab Vol No.523 | “Sample Receipt Temperature = 4°C” — Was the Sample Kept at 4°C for the Whole Journey?
A Primary 5/6 evidence guide to sample receipt temperature: why a 4°C arrival reading is not automatically a continuous cold-chain history, and what evidence would strengthen the claim.
