PSLE Science Reality Lab Vol No.013 | “Energy-Saving” — Were Both Devices Doing the Same Job?
A Primary 5/6 PSLE Science Reality Lab guide to evaluating energy-saving claims by checking useful output, test duration, operating conditions, system boundaries and whether lower energy use still means a fair comparison.
-
PSLE Science Reality Lab Vol No.012 | “Biodegradable” — Under What Conditions, and How Long Does It Take?
A Primary 5/6 PSLE Science Reality Lab guide to evaluating biodegradable claims by checking test conditions, time, what was measured, what remained after testing and whether one environment supports a wider disposal claim.
-
PSLE Science Reality Lab Vol No.011 | “No Germs Detected” — Does That Mean There Were None?
A Primary 5/6 PSLE Science Reality Lab guide to understanding non-detection: what was sampled, how sensitive the method was, what controls were used and why “not detected” is not automatically the same as “none exist”.
-
PSLE Science Reality Lab Vol No.010 | “Lab Tested” — Does the Result Still Hold Outside the Laboratory?
A Primary 5/6 PSLE Science Reality Lab guide to evaluating “lab tested” claims by checking tested conditions, changed real-world conditions, measured outcomes, alternatives and how far the conclusion can travel.
-
PSLE Science Reality Lab Vol No.009 | “Every Trial Worked” — Were the Failed Trials Left Out?
A PSLE Science Reality Lab guide for Primary 5 and 6 learners on evaluating impressive success claims by asking how many trials were attempted, what counted as success and whether the complete record is visible.
-
PSLE Science Reality Lab Vol No.008 | “Three Websites Say the Same Thing” — Is That Three Pieces of Evidence?
A PSLE Science Reality Lab guide for Primary 5 and 6 learners on tracing repeated claims back to their evidence source and distinguishing repeated reporting from independent scientific evidence.
