This document discusses teaching content about light using CLIL (Content and Language Integrated Learning) methods. It lists potential biology, physics, astronomy, and environmental topics related to light including photosynthesis, phototropism, bioluminescence, units conversion, nature of light, light pollution, and energy sources and uses. It proposes developing cognitive skills and having students explore their prior knowledge about light through an activity called "Map in the Middle" which involves students individually and collaboratively mapping what they remember about light on a large paper.
