1) The document outlines a lesson plan about food chains for 5th grade students. The teacher implemented some changes during the lesson, including having students discuss in pairs what would happen if parts of the food chain disappeared instead of working individually. 2) The lesson included an introductory discussion, explaining food chains using a photocopy, an online game about food chains, and an assessment activity where students answered questions about a food chain picture in pairs. 3) The teacher reflected that practicing in pairs for the assessment worked better than individually, as some students were able but others struggled, and collaborating prevented discouragement. The experience was a good opportunity to plan, teach, and reflect on a CLIL lesson.
