A Primary 5/6 PSLE Science Reality Lab guide to evaluating “recyclable” claims by separating material possibility from real collection, sorting, contamination, processing and recovery conditions.

A Primary 5/6 PSLE Science Reality Lab guide to reading certification and standards marks scientifically: identify the exact requirement checked, the scope of the assessment, who assessed it, and which wider claims the mark does not prove.

A Primary 5/6 PSLE Science Reality Lab guide to evaluating claims that use foam as proof of better cleaning by separating a visible proxy from the target outcome, designing a fair comparison and checking whether the indicator is actually validated.

A Primary 5/6 PSLE Science Reality Lab guide to evaluating computer simulations by separating observations from model inputs, rules, outputs and predictions, then checking the model against real evidence.

A Primary 5/6 PSLE Science Reality Lab guide to evaluating “waterproof” claims by asking what was tested, under what water exposure, for how long, what counted as failure and how far the result can travel.

A Primary 5/6 PSLE Science Reality Lab guide to evaluating “up to” claims by separating the best observed result from typical performance, checking the full range, baseline, test conditions and how often the maximum occurred.
