This document discusses teaching content about light using CLIL (Content and Language Integrated Learning) methods. It lists potential topics like photosynthesis, bioluminescence, astronomy, the nature of light, light pollution, energy uses and sources. It proposes developing cognitive skills through an activity where students build a "map in the middle" to explore their prior knowledge on the topic. It suggests including cultural elements like a visit to the National Botanic Garden and creating a "photosynthesis song". The document thanks the readers at the end.
