How the digestive system works - complete lesson (GCSE 1-9)

This lesson is based on the new AQA SOW (B3.6) but can be used for others. This lesson includes the required practical. The lesson outlines key information relating to the digestive system and enzymes, students fill in a table handout during the presentation of these slides. The table is then self/peer marked to ensure key information is present. The practical is then introduced (a brief demonstration may be beneficial here) to and conducted by the students. Those who finish in good time are prompted to draw a graph and identify the variables within the experiment. An extra stretch is based on students suggesting improvements to the techniques used during the experiment. This is followed by a discussion of results and ‘what should of been seen’. The plenary is based on students reflecting on their progress against the learning objectives, and sharing this with the class.
