The chemistry calculation builder generates calculation questions with worked solutions, laid out step by step. Five scaffold levels run from a full worked example down to blank lines for independent practice.
A hand-built replica of the real builder page, not a screenshot. Every control shown exists in the product.
The demo question asks for a relative formula mass from moles and mass. Level one reveals the worked solution a step at a time. Level two blanks one value per step, level three blanks every value including the equation itself, and levels four and five strip the working back to labelled and then bare boxes for pupils to attempt.
Each question is generated with clean numbers, so the arithmetic never gets in the way of the method. Choose the calculation and what to make the subject, from moles and masses to concentrations and gas volumes, and generate a fresh question whenever the class needs another go.
Diagnostic multiple choice. Each answer reveals what the class does and doesn't understand.
Click a number and watch it land on a question at random. Built for cold-call questioning.
Automate show, cover, and recall tasks. Great for memorising diagram features or keywords.
Questions beside a visual stimulus. A YouTube clip, diagram, graph, or a paragraph to read closely.
Shell diagrams for atoms and ions, with dots or crosses, hidden electrons and side-by-side comparison.
Dot-and-cross diagrams for ionic and covalent bonding, with a stepped build-up, hidden electrons and labels.
Curated, balanced GCSE reaction equations, ready to blank for recall.
Every tool turns a few inputs into a clean, exam-ready diagram.
Practical results tables with repeat readings, a mean and an optional anomaly, plus curated reference data.
Upload any diagram and the labels are suggested for you to drag, edit and blank.
