PSLE Science Reality Lab Vol No.093 | “No Added Substance Q” — Does That Prove the Final Product Contains None?
A Primary 5/6 PSLE Science Reality Lab guide to “no added” claims: learn to separate a manufacturing-process statement from a measurement claim about what is present in the final product.
-
PSLE Science Reality Lab Vol No.093 | “No Added Substance Q” — Does That Prove the Final Product Contains None?
A Primary 5/6 PSLE Science Reality Lab guide to packaging language: learn to distinguish a statement about what was not deliberately added during manufacture from evidence that none is present in the final product.
-
PSLE Science Reality Lab Vol No.092 | “Measured to 12.347” — Do Extra Decimal Places Mean the Experiment Measured That Precisely?
A Primary 5/6 PSLE Science Reality Lab guide to false precision: learn why calculator output and extra decimal places can show more digits than the original measurements actually support.
-
PSLE Science Reality Lab Vol No.091 | “We Used the Same Test Surface for Both” — Did the First Trial Change the Starting Conditions for the Second?
A Primary 5/6 PSLE Science Reality Lab guide to sequential product demonstrations: learn to check whether the first trial changed the shared surface, specimen or apparatus before the second test began.
