I've been teaching A-level biology for years and have spent several hours developing resources to the highest possible standard. They are designed to maximise class time - spending less time on learning facts, with a focus on application and the processing of information.

PowerPoint introducing gas exchange in fish. Brief animation to explain the countercurrent mechanisms, but it's quite a short PowerPoint (hence the price) and is really designed to be used with the class notes for this topic. The PPT contains notes with most of the answers to the questions on the PPT. Also included is a model students can make of fish gills, including lamella. The idea is they draw on the direction of the blood flow and direction of water movement across the gill filament.
