Purpose

Students will engage in a collaborative jigsaw activity that highlights different sustainable farming techniques and their impacts on soil health. Working in expert groups, students will research and evaluate various methods, such as crop rotation, cover cropping, and organic composting. Then, through peer-teaching in jigsaw groups, they will discuss how these practices can reduce soil erosion and enhance soil fertility compared to traditional agriculture. This hands-on experience encourages critical thinking and problem-solving as students connect theoretical knowledge with real-world applications.

Learning goals

Students will investigate various farming practices to understand their impact on soil health, analyzing differences between traditional and sustainable methods. They will work in groups to research real-world examples, focusing on how sustainable practices like crop rotation, cover cropping, and no-till farming can prevent soil degradation. Each group will present their findings, discussing how sustainable farming can enhance soil quality and recommending strategies for improving agricultural practices.

Products

Students will collaboratively create a jigsaw infographic that illustrates various soil degradation issues caused by traditional agriculture, such as erosion, compaction, and loss of fertility. Each group will research a specific sustainable farming method, like crop rotation, cover cropping, or agroforestry, and present real-world solutions and their impact on soil quality improvement. The completed infographics will be shared in a gallery walk format, where students will engage with peer presentations and discuss the potential benefits and challenges of implementing sustainable practices in their own communities or school gardens.

Launch

Begin the lesson with a hands-on soil observation activity by providing small soil samples from different farming methods, such as conventional, organic, and permaculture. Have students use magnifying glasses to observe and record characteristics like color, texture, and moisture. Prompt students to discuss their observations in small groups, considering how each sample might affect plant growth and soil health. Conclude the launch with a brief round-robin where each group shares one observation that might relate to sustainable farming and soil quality.

Exhibition

Students will work in small groups to create visual presentations that demonstrate their insights into sustainable farming methods and their impact on soil quality. Each group will design an engaging display board or digital slideshow that includes data, images, and compelling arguments for why specific sustainable practices could effectively address soil degradation issues. These presentations will culminate in a gallery walk, where students move between stations to discuss and critique each other's work. Guests from the local farming community could be invited for feedback and to provide real-world context to the students' findings.
