AI is here to Stay
Mr E used to spend her Sunday nights bent over a stack of exam papers, red pen in hand, the same tired questions staring back at her year after year. Then one afternoon a colleague mentioned something odd: an AI had drafted a full memo for chemical equilibrium in the time it took her to […]
Aether
Title: A Digital Globe Worth Spinning: Exploring Earth with Aether Every so often a small web tool comes along that’s just fun to play with — and happens to be useful for teaching too. Aether is one of those. It’s an interactive 3D globe, built with Grok, showing Earth at night with lights scattered across […]
Where the Marks Actually Are: Breaking Down the Physics Paper 1 Weighting
If you’re revising for Physical Sciences Paper 1 and dividing your time equally across every topic, you’re probably studying wrong — not because the other sections don’t matter, but because the mark distribution isn’t equal, and it never has been. Here’s how a typical 150-mark Physics Paper 1 breaks down: Mechanics — 65 marks Electricity […]
Simulation: Percentage Purity
# A New Way to Practise Percentage Purity — Without the MessGrade 11 learners doing the Quantitative Aspects experiment this term know the drill: crush the chalk, add it to the acid, watch the mass drop as CO₂ escapes, then work backwards to find how pure the sample really was. It’s a good practical, but […]
Percentage Purity: A Complete Guide with Worked Examples
Percentage purity is one of those topics that looks simple on paper but trips learners up in the exam room — usually because the question hides an extra step before you can even use the formula. This guide walks through the concept from the ground up and works through four increasingly demanding examples. What is […]
Organic Chemistry Errors: 2024 vs 2025 NSC Diagnostic Reports Compared
The Department of Basic Education’s NSC Diagnostic Reports break down exactly where Physical Sciences candidates lose marks, question by question. Comparing the organic chemistry sections — Questions 2 to 4 in Paper 2 — across the 2024 and 2025 reports shows how much of the same ground keeps getting lost, and where new problems are […]
Back Titration: What It Is and When You Need It
Some substances don’t titrate well on their own. Maybe the reaction with your usual reagent is too slow, maybe there’s no clear endpoint, or maybe the substance you’re testing is insoluble and won’t react cleanly in solution. Back titration exists for these cases. The idea is simple, even if it feels roundabout the first time […]
