Chemistry graph builder
The graph builder draws accurate chemistry graphs for the board, sized for the room and free to download. Reaction profiles come ready made for named GCSE reactions, and rate of reaction graphs come with experimental data and an anomaly on a toggle.

Why this works in Chemistry
A reaction profile sketched freehand never quite keeps its levels straight, and pupils read meaning into the wobble. Here the curve is computed from the reaction data, the activation energy arrow and overall energy change are placed where they belong, and each label switches off when you want the class to add it.
Reading data from a graph is a key skill in the specification, and exam standard graphs give it far more depth than a sketch. Download the finished graph for a worksheet or assessment, or use it in questions within Plenary Studio with a free account.

Multiple choice questions
Diagnostic multiple choice. Each answer reveals what the class does and doesn't understand.
Random number match
Click a number and watch it land on a question at random. Built for cold-call questioning.
Memorise and recall
Automate show, cover, and recall tasks. Great for memorising diagram features or keywords.
Stimulus questions
Questions beside a visual stimulus. A YouTube clip, diagram, graph, or a paragraph to read closely.
Electron configuration
Shell diagrams for atoms and ions, with dots or crosses, hidden electrons and side-by-side comparison.
Bonding diagram
Dot-and-cross diagrams for ionic and covalent bonding, with a stepped build-up, hidden electrons and labels.
