This document discusses using the KWL strategy to teach about global warming. It begins with an introduction to KWL charts and how they work by having students identify what they Know, Want to know, and have Learned. It then provides a sample KWL chart on global warming where students listed what they already knew about causes and effects of global warming, questions they had, and space to add what they learned. The document defines key terms, lists causes and effects of global warming with images, and proposes solutions. It concludes by directing students to watch an explanatory video and complete the final L column of the KWL chart.

- 27. • Greenhouse Gas: A gas which traps the sun's heat: • Water vapor (H2O) • Carbon dioxide (CO2) - exhaust from cars and power plants (electricity). • Methane (CH4) - from decomposing organic matter. 27
- 28. 28 - The greenhouse effect is when the temperature goes up, on Earth, since the sun’s heat and light energy is trapped in the earth’s atmosphere. - While the heat from the sun enters our atmosphere, the heat has trouble leaving back out our atmosphere
