In this lesson, students discussed the concept of the universe, focusing on how the sun is at its center and how planets, including Earth, revolve around it. They examined the idea of global warming, its causes—which include burning fossil fuels and deforestation—and its effects, such as rising temperatures, extreme weather events, and sea-level rise due to ice melting. The lesson highlighted the consequences of global warming, including the risk of animal and plant extinction, and the social implications like food shortages and health issues. Finally, the importance of transitioning to cleaner energy sources as a solution was emphasized.
