A complete, ready-to-teach lesson: animated PowerPoint, interactive AfL activity, a worksheet and a scaffolded worksheet (both with answers) and homework. The whole of Physical chemistry pulled into three threads: energy, collisions and catalysts. Pupils finally see how ΔH, rate, activation energy and yield connect. After the three threads and a “Which is bigger?” activity, pupils sit an 18-minute timed section in silence, then swap and mark a partner’s sheet with the answers. The plenary puts a full explanation in order, and the homework is final revision on two reactions the lesson never uses.
