The document summarizes a lesson plan about food chains that was implemented in a 5th grade class. The teacher introduced the concept of food chains through an introductory text and discussion. To help students understand what would happen if part of the chain disappeared, the teacher had them discuss it in pairs and share their reflections. The lesson included an online game about food chains and an assessment activity where students answered questions about a food chain picture in pairs. Based on reflections, the teacher realized students needed more practice with food chains, so changed the final activity to be done collaboratively rather than individually.
