PSLE Science Reality Lab Vol No.471 | “Phase-Folded Light Curve” — Is This One Continuous Orbit?
A massive Primary 5/6 PSLE Science Reality Lab guide to phase-folded light curves: learn why repeated cycles can appear as one tidy curve, how to recover the original time evidence, and how to test whether the pattern supports the claim.
-
PSLE Science Reality Lab Vol No.470 | “Research Grade” — Does That Mean the Species Identification Is Definitely Correct?
A massive Primary 5/6 PSLE Science Reality Lab guide to Research Grade citizen-science observations: learn what the status criteria mean, why community agreement is useful but not infallible, and how provenance and scope control scientific claims.
-
PSLE Science Reality Lab Vol No.469 | “GPS Track” — Did the Animal Really Walk Along Every Straight Line on the Map?
A massive Primary 5/6 PSLE Science Reality Lab guide to animal GPS tracks: learn why recorded fixes are evidence while straight connecting lines are representations, and how time gaps, missing fixes, location error and obstacles limit route claims.
-
PSLE Science Reality Lab Vol No.468 | “Data Deficient” — Does That Mean the Species Is Safe, Rare or Unstudied?
A massive Primary 5/6 PSLE Science Reality Lab guide to IUCN Data Deficient status: learn why insufficient extinction-risk evidence does not mean safe, threatened, rare or wholly unstudied, and how to identify the missing evidence.
-
PSLE Science Reality Lab Vol No.467 | “Holotype” — Is This Specimen the Average Member of the Species?
A massive Primary 5/6 PSLE Science Reality Lab guide to holotype labels: learn why a name-bearing reference specimen is not automatically an average or typical member of its species, and how additional evidence is needed before generalising.
-
PSLE Science Reality Lab Vol No.466 | “Raw Image” — Is This Exactly the Original Science Data From the Spacecraft?
A massive Primary 5/6 PSLE Science Reality Lab guide to scientific images labelled “raw”: why a quick public image can be largely unprocessed yet still not be the original archival science-data product, and how provenance, metadata and processing control what the image can prove.
