PSLE Science Reality Lab Vol No.222 | “In the Habitable Zone” — Does That Mean the Planet Is Habitable?
A Primary 5/6 PSLE Science Reality Lab guide to the habitable zone: learn why orbital location can make surface liquid water possible without proving a planet is habitable or inhabited.
-
PSLE Science Reality Lab Vol No.221 | “High Landslide Susceptibility” — Is a Landslide Forecast for This Place?
A Primary 5/6 PSLE Science Reality Lab guide to landslide maps: learn why high susceptibility marks terrain more prone to landsliding, not a time-specific forecast that a landslide is imminent or certain.
-
PSLE Science Reality Lab Vol No.220 | “Organic Molecules Detected” — Does That Mean Scientists Found Life?
A Primary 5/6 PSLE Science Reality Lab guide to astrobiology headlines: learn why detecting organic molecules is chemical evidence, not by itself proof that living organisms made them.
-
PSLE Science Reality Lab Vol No.219 | “Earth-Sized Exoplanet” — Does That Mean Another Earth?
A Primary 5/6 PSLE Science Reality Lab guide to exoplanet headlines: learn why “Earth-sized” describes size evidence, not proof of an Earth-like atmosphere, surface, habitability or life.
-
PSLE Science Reality Lab Vol No.218 | “Tornado Rated EF3” — Was the Wind Speed Directly Measured?
A Primary 5/6 PSLE Science Reality Lab guide to tornado EF ratings: learn why an EF3 rating is inferred from surveyed damage and estimated wind ranges, not a direct wind-speed reading everywhere along the tornado path.
-
PSLE Science Reality Lab Vol No.217 | “Specific Gravity = 3.0” — Is Every Piece Three Times Heavier Than Water?
A Primary 5/6 PSLE Science Reality Lab guide to specific gravity: learn why SG 3.0 is a density ratio to a reference and only implies a 3:1 mass ratio for equal volumes, not arbitrary objects.
