PSLE Science Reality Lab Vol No.025 | “Eco-Friendly” — Which Environmental Result Was Actually Measured?
A Primary 5/6 PSLE Science Reality Lab guide to evaluating broad “eco-friendly” claims: turn the slogan into measurable outcomes, identify the comparison and system boundary, look for trade-offs, and keep conclusions within the evidence.
-
PSLE Science Reality Lab Vol No.024 | “50% Recycled Material” — 50% of What?
A Primary 5/6 PSLE Science Reality Lab guide to reading recycled-content percentages: identify the product part, material and denominator, then separate composition evidence from recyclability, durability and wider environmental claims.
-
PSLE Science Reality Lab Vol No.023 | “We Tested 100 Samples” — Were They All From the Same Batch?
A Primary 5/6 PSLE Science Reality Lab guide to evaluating large-sample claims: distinguish many measurements from representative coverage, check batches and sources, and limit conclusions to what was actually sampled.
-
PSLE Science Reality Lab Vol No.022 | “Look at the Before and After” — Are the Two Pictures Really Comparable?
A Primary 5/6 PSLE Science Reality Lab guide to evaluating before-and-after photographs: check viewpoint, scale, lighting, timing, object identity and measurement conditions before treating a visual difference as scientific evidence of change.
-
PSLE Science Reality Lab Vol No.021 | “The Picture Is Twice as Big” — Does a Bigger Icon Mean a Bigger Scientific Effect?
A Primary 5/6 PSLE Science Reality Lab guide to evaluating infographics that resize pictures or icons: return to the numbers, distinguish length from area and volume, check the visual scale, and stop decoration from exaggerating a scientific effect.
-
PSLE Science Reality Lab Vol No.020 | “The Company Paid for the Study” — Does Funding Decide Whether the Result Is True?
A Primary 5/6 PSLE Science Reality Lab guide to evaluating sponsored research without treating funding as automatic proof or disproof: examine the method, transparency, outcome choices, reporting and independent evidence.
