Evaporation and transpiration - complete lesson (GCSE 1-9)

A full differentiated lesson based on the new AQA B4.8 SOW. The lesson covers the stomata, diffusion of gases, guard cells and transpiration. Student knowledge is applied to a differentiated question grid with a opportunity to ‘stretch’ towards a PP GCSE question - rewards are useful here! Students then take part in a simple practical where they use nail varnish, tape and microscopes to observe and count the stomata on a leaf, comparing the topside to the bottom side. A video is included to show how this is done but a demonstration is useful here. There is then a review of ‘what the students should of found’ followed by a plenary which encourages students to reflect on their progress against the learning objectives. All answers incorporated into the slides to facilitate self/peer marking and correction
