PSLE Science Reality Lab Vol No.144 | “This Is an Artist’s Impression” — Did a Telescope Actually Photograph the Scene?
A Primary 5/6 PSLE Science Reality Lab guide to artist impressions in science: learn how measurements, models and illustrative choices combine—and why a scientifically informed image is not automatically a direct photograph.
-
PSLE Science Reality Lab Vol No.143 | “The Camera Trap Took 1,000 Photos” — Does That Mean 1,000 Animals Were There?
A Primary 5/6 PSLE Science Reality Lab guide to camera-trap evidence: learn why photographs, detection events, camera locations and unique animals are different scientific quantities, and how sampling effort changes what a wildlife count can support.
-
PSLE Science Reality Lab Vol No.142 | “The Microscopy Image Is Brighter” — Does That Prove There Is More of the Fluorescent Target?
A Primary 5/6 PSLE Science Reality Lab guide to scientific image brightness: learn why brighter fluorescence can reflect more target, different exposure or gain, background, saturation or calibration—and how to decide what the image can really support.
-
PSLE Science Reality Lab Vol No.141 | “The Strange Result Was Repeated and Confirmed” — Does One Verified Outlier Become the General Rule?
A Primary 5/6 PSLE Science Reality Lab guide to verified outliers: learn how to separate evidence that an unusual result is real from evidence that it is typical, common or general enough to support a broad scientific claim.
-
PSLE Science Reality Lab Vol No.140 | “42 Samples Were Positive” — How Much Did the Cutoff Create the Count?
A Primary 5/6 PSLE Science Reality Lab guide to scientific cutoffs: learn how continuous measurements become positive/negative or pass/fail counts, why cases near a threshold can switch category without changing physically, and what a headline count can really support.
-
PSLE Science Reality Lab Vol No.139 | “This Map Cell Is Blank” — Does Blank Mean the Value Is Zero?
A Primary 5/6 PSLE Science Reality Lab guide to missing scientific data: learn why a blank map cell, table entry or sensor gap is not the same as a measured zero, and how quality flags and provenance change the claim.
