PSLE Science Reality Lab Vol No.224 | “Tensile Strength = 500 MPa” — Can Any Object Made From It Hold the Same Load?
A Primary 5/6 PSLE Science Reality Lab guide to tensile-strength claims: learn why MPa describes stress under a defined test, not one fixed load every object can carry.
-
PSLE Science Reality Lab Vol No.223 | “Suitable Habitat” on the Map — Is the Species Actually Present Everywhere It Is Coloured?
A Primary 5/6 PSLE Science Reality Lab guide to habitat-suitability maps: learn why coloured suitable habitat is modelled potential, not proof a species occupies every mapped place.
-
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.
