Feedback and what you get

Questions are marked automatically as pupils answer: a sound and a character reaction show straight away whether they are right, and correct answers earn points, with a results screen at the end. Sentence-writing tasks are for pupils' own answers and are not marked automatically.

A 22-slide interactive lesson that runs in any web browser on a computer, tablet or interactive whiteboard. Members open it online from their year group page. Buying it on its own gives you a .zip download to unzip and open.

Some reactions warm things up and others make them cold — from cooking gas flames to instant ice packs. This 22-slide interactive lesson on exothermic reactions takes pupils from first ideas to exam-style explanations, with 13 self-marking activities and nothing to prepare beforehand.

Teaching Exothermic and Endothermic Reactions in GCSE Chemistry

Pupils classify reactions as exothermic or endothermic from temperature changes, link them to uses such as hand warmers and cold packs, and interpret reaction profiles including activation energy. They explain energy changes in terms of breaking and making bonds, calculate overall energy changes from bond energies, and explain why the temperature change practical uses an insulated cup.
