Description: This video introduces the water sowing technique, which is used by a coffee grower in Antioquia, Colombia to conserve water sources on his farm. A mixture of sea salt, brown sugar and gravel or river stones stimulates water retention and filtration in the soil, making it available over time. The documentary emphasizes the importance of the water cycle and the necessity of managing this resource sustainably.
Teaching ideas: The title’s question is an ideal entry point for in-class discussion. Before watching, students can discuss in pairs what they think the phrase means and whether they consider it possible, practicing structures for expressing opinions, hypotheses and possibility. After watching, students can explain the water sowing technique in their own words as if describing it to someone unfamiliar with it, using the present tense and instructional vocabulary to convey how the mixture of salt, sugar, and gravel works to retain and filter water in the soil. Through the video’s YouTube comment section students can work with authentic, informal Spanish: they can read and categorize comments as positive, skeptical, informative, or argumentative, identifying qualifying adjectives and opinion markers, and then use this language to stage a brief class debate about whether the technique could be applied more widely. Finally, students can reflect on what the coffee grower’s example suggests about the relationship between small-scale agricultural knowledge and broader climate adaptation strategies, practicing connectors for drawing conclusions.
