A massive Primary 5/6 PSLE Science Reality Lab guide to astronomy-image evidence: learn why total exposure time can be accumulated from many separate frames, filters and observing periods, and how to distinguish a combined scientific image from one continuous photograph.

A massive Primary 5/6 PSLE Science Reality Lab guide to five-sigma science headlines: what 5σ does and does not say, why it is not a five-times-stronger signal claim, and how to evaluate the background model, evidence scope and alternative explanations.

A massive Primary 5/6 PSLE Science Reality Lab guide to lightning-count evidence: learn why events, groups and flashes are different counting objects, how satellite detection rules create the reported number, and how to test claims before treating one count as 100 separate lightning flashes.

A massive Primary 5/6 PSLE Science Reality Lab guide to funnel plots: learn why asymmetry can signal a small-study pattern without proving hidden studies or publication bias, and how to test alternative explanations with scientific evidence.

A massive Primary 5/6 PSLE Science Reality Lab guide to reading wind streamline maps: learn why an instantaneous streamline is not automatically the trajectory of one air parcel, how animation can mislead, and what evidence is needed before turning a flow field into a path claim.

A massive Primary 5/6 PSLE Science Reality Lab guide to instrument warm-up: learn why a steady display immediately after switch-on may not mean stable measurement performance, and why warm-up is a test condition rather than a guarantee of perfect accuracy.
