PSLE Science Reality Lab Vol No.045 | “95% Accurate” — Accurate on Which Data?
PSLE-SCI-REALITY-0045. A massive Primary 5/6 Reality Lab guide to accuracy claims: ask which cases built the model, which cases truly tested it, whether test cases resemble real use, and what the headline percentage hides.

PSLE Science Reality Lab Vol No.044 | “The Model Fits the Data” — Does That Prove the Explanation?
PSLE-SCI-REALITY-0044. A massive Primary 5/6 Reality Lab guide to model-fit claims: separate observations from fitted lines, inspect the errors left behind, compare alternative explanations, and test whether the model predicts new evidence.

PSLE Science Reality Lab Vol No.043 | “The Blank Sample Was Clean” — What Contamination Did That Actually Check?
PSLE-SCI-REALITY-0043. A massive Primary 5/6 Reality Lab guide to blank samples: trace where the blank travelled, identify which contamination pathway it could detect, and keep a clean blank from becoming a universal guarantee.
-
PSLE Science Reality Lab Vol No.042 | “Blind Tested” — What Did the Tester Not Know?
PSLE-SCI-REALITY-0042. A massive Primary 5/6 Reality Lab guide to evaluating “blind tested” scientific claims: identify what information was hidden, what bias pathway that protects against, and what blinding still cannot prove.
-
PSLE Science Reality Lab Vol No.041 | “The Forecast Says 30°C” — Is That One Certain Future?
PSLE-SCI-REALITY-0041. A Primary 5/6 Reality Lab guide to scientific forecasts: distinguish a single displayed prediction from a range of plausible model outcomes, inspect spread and updates, and keep uncertainty inside the evidence.

PSLE Science Reality Lab Vol No.040 | “The Pixel Has a Number” — What Does Its Quality Flag Say?
PSLE-SCI-REALITY-0040. A Primary 5/6 Reality Lab guide to scientific quality flags: distinguish a displayed value from evidence about how trustworthy that value is before using it in a claim.
