Objective: This worksheet aims to educate students about the greenhouse effect, including its natural process, causes, effects, and methods of mitigation, with a specific focus on one greenhouse gas.

Content and methods: The worksheet begins by prompting students to brainstorm their existing knowledge about the greenhouse effect and organize it into a mind map. A sample mind map is provided for teachers, outlining causes, greenhouse gases, effects, and mitigation strategies. Students then watch a YouTube video titled "What Is the Greenhouse Effect?" and fill in blanks in a summary text, covering how the greenhouse effect warms Earth, the role of greenhouse gases, human activities' impact, and global warming. A detailed informational text about a selected greenhouse gas follows, describing its properties, origin, occurrence, and significant contribution to the greenhouse effect. Students are asked to fill out a profile for the greenhouse gas based on this text. Finally, a crossword puzzle challenges students to recall terms related to the gas and the greenhouse effect.

Competencies:

• Knowledge acquisition about the greenhouse effect, greenhouse gases, and climate change
• Reading comprehension and information extraction
• Information organization through mind mapping and profile completion
• Vocabulary recall and puzzle-solving
• Understanding of scientific concepts and their real-world implications

Target group: 7th-10th grade

SDGs:

• 13th goal (“Take urgent action to combat climate change and its impacts”): The worksheet explains the greenhouse effect as a natural process intensified by human activities like burning fossil fuels, which leads to global warming. It specifically highlights the high potency of methane as a greenhouse gas and emphasizes that controlling its emissions is a priority for climate mitigation.
• 15th goal (“Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss”): The material discusses methane origins from biological activities within terrestrial ecosystems, such as wetlands and the digestion processes of ruminant animals. It underscores that understanding these natural and human-induced emissions is essential for protecting the planet for future generations.
