The document outlines a Year 5 science lesson plan about food chains for 30 pupils. The lesson involves identifying animals' food sources, defining producers and consumers, explaining the concept of energy transfer through a food chain using plants and arrows, and demonstrating food chains using animal masks. Students will observe, classify, infer, communicate, predict, sequence, relate, attribute and generate ideas. The goals are for pupils to understand how to construct food chains and identify producers and consumers.
