THIS RESOURCE IS FREE (AND EVERYTHING ELSE IN THIS TOPIC) I believe it is our collective responsibility to deliver this topic with as much impact as possible, ensuring that students truly grasp the significance of human influences on ecosystems on an international scale. By giving students a voice to discuss these issues and empowering them to actively contribute to the creation of a sustainable future, they can start to inspire change in themselves, the people around them and (hopefully one day) the wider world. ✓ Engaging presentation ✓ Recaps previous learning ✓ Lots of short AFL tasks ✓ Exam question examples This lesson on Food Supply is designed for KS4 Science students enrolled in the CIE Cambridge IGCSE Biology 0610 (2023-25) course. This is the first lesson in the topic 20 Human Influences on Ecosystems. The lesson recaps previous learning from other linked topics to ensure students have a strong foundation before diving into the material. It also includes concise and easy-to-understand information and a variety of quick assessment for learning tasks to help students solidify their understanding of the topic. There is a strong emphasis on answering exam questions, with examples and the mark scheme included in the presentation. Objectives: Describe how humans have increased food production, limited to: (a) agricultural machinery to use larger areas of land and improve efficiency (b) chemical fertilisers to improve yields © insecticides to improve quality and yield (d) herbicides to reduce competition with weeds (e) selective breeding to improve production by crop plants and livestock Describe the advantages and disadvantages of large-scale monocultures of crop plants Describe the advantages and disadvantages of intensive livestock production This lesson would also be adaptable for all GCSE students (whether AQA, Edexcel, OCR) and great for KS3 Science or as a GCSE revision resource.
