Students act as urban agriculturalists to combat local food insecurity by designing a 'Smart Crop Guardian' garden optimized for their specific climate. Through a blend of geometric modeling, climate data analysis, and ethical AI integration, learners develop nutrient-dense agricultural solutions aligned with the UN Sustainable Development Goal of Zero Hunger. The project culminates in a 3D prototype and pitch that demonstrates how human-led technological auditing can maximize community health and sustainability.

Entry Events

Events that will be used to introduce the project to students

The 2030 Broadcast: A Call for Digital Guardians

Students receive a 'glitchy' video transmission from a (fictional) 'Global Food Security Network' in the year 2030. In the video, a digital activist explains that the world successfully reached SDG 2 (Zero Hunger) thanks to young 'Ethical AI Guardians' who documented their inventions. The transmission ends with a call to action: 'We need your story to show the world how technology and empathy saved our food supply.' A local media producer then enters the room to explain that the students' task is to research climate-resilient crops, build a 'Smart Crop Guardian' prototype, and star in a professional-grade advocacy video that proves AI can be used for good.

The Ethical AI Film Festival Challenge

An invitation arrives from the 'Global Youth Tech-for-Good Film Festival.' The festival is looking for 6th-grade teams who can solve two problems: 1) Designing an AI-powered urban garden (The Smart Crop Guardian) and 2) Producing a persuasive video that teaches others how to use climate data ethically. Students watch a high-energy trailer for the festival and are told their final 'Smart Crop Guardian' prototype must be the centerpiece of their film. They realize that their research and math-based garden layouts aren't just for a grade—they are the 'script' for a video that could inspire a global audience.

Portfolio Activities

Portfolio Activities

These activities progressively build towards your learning goals, with each submission contributing to the student's final portfolio.
Activity 1

The Urban Hunger Hunt: Identifying Local Needs

Before designing a solution, students must understand the problem of food insecurity within their own community. In this activity, students investigate local 'food deserts' and the socio-economic barriers that prevent neighbors from accessing nutrient-dense food. They will use digital maps and local news sources to identify areas in need and connect these findings to the UN Sustainable Development Goal 2.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Use an online mapping tool (like the USDA Food Access Research Atlas) to identify low-access census tracts in your city or county.
2. Research local statistics on poverty rates and the proximity of grocery stores vs. fast food outlets in these areas.
3. Write a summary explaining how a lack of fresh produce in these specific areas contributes to the 'Zero Hunger' challenge.

Final Product

What students will submit as the final product of the activityA 'Community Food Security Profile' consisting of an annotated digital map and a 1-page summary of local barriers to nutrition.

Alignment

How this activity aligns with the learning objectives & standardsAligns with SDG 2: Zero Hunger (understanding food security) and ELA Research Inquiry and Synthesis (conducting research to answer a question).
Activity 2

Climate Detectives & Nutrient Heroes

Students act as 'Climate Detectives' to gather local environmental data (average rainfall, sunlight hours, and temperature ranges) for their specific zip code. They then cross-reference this data with a 'Nutrient Hero' database (plant growth charts) to select three high-yield, nutrient-dense crops that are most likely to thrive in their local urban conditions.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Access local weather databases to find the average high/low temperatures and rainfall for the last three growing seasons.
2. Research the 'Nutrient Density' of various vegetables (e.g., kale, sweet potatoes, beans) and their specific growth requirements.
3. Select three 'Hero Crops' that match your local climate profile and justify your choices based on the data.

Final Product

What students will submit as the final product of the activityA 'Crop Suitability Matrix' that matches local climate data points with specific plant requirements.

Activity 3

Plotting Productivity: The Geometry of Space

Using the crops selected in the previous activity, students must now design a physical layout for their garden. They will be given a specific urban 'plot' (a complex polygon shape, like an L-shaped rooftop or a triangular vacant lot). Students must calculate the total area and partition the space for their different crops based on required spacing for maximum yield.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Draw your assigned urban plot on graph paper or a digital drawing tool, ensuring it is a complex polygon (e.g., a combination of rectangles and triangles).
2. Decompose the complex shape into simpler quadrilaterals and triangles to calculate the total square footage.
3. Allocate specific 'zones' for your Hero Crops based on the area each plant needs to grow successfully, ensuring no space is wasted.

Final Product

What students will submit as the final product of the activityA scaled geometric blueprint of the garden plot with all area calculations shown and labeled.

Alignment

How this activity aligns with the learning objectives & standardsAligns with Mathematics: Area and Geometry (finding area of polygons by composing/decomposing shapes).
Activity 4

AI Co-Designer: The Ethical Auditor Lab

In this activity, students will use an AI image generator or a layout optimization tool to suggest improvements to their geometric blueprints. However, they must act as 'Ethical Auditors.' They will compare the AI's suggestions against their own research to see if the AI ignored local climate constraints or prioritized aesthetics over nutrient yield. They will also discuss the ethics of using AI in agriculture (e.g., who owns the data?).

Steps

Here is some basic scaffolding to help students complete the activity.
1. Input your garden dimensions and crop choices into an AI tool (like a generative image tool or a specialized garden planner) to see its 'ideal' layout.
2. Critically evaluate the AI's output: Did it place a sun-loving plant in a shaded area? Did it ignore water access? Annotate these errors.
3. Reflect on the 'Human-in-the-Loop' concept: Why is it important for a human agriculturalist to make the final decision rather than just trusting the AI?

Final Product

What students will submit as the final product of the activityAn 'AI Audit Report' featuring the AI-generated layout, a list of corrections made by the student, and a reflection on the ethical use of AI.

Alignment

How this activity aligns with the learning objectives & standardsAligns with Computer Science: Ethical Use of Technology (identifying bias and ethical concerns) and SDG 2 (using technology to solve hunger).
Activity 5

The Guardian Blueprint: Final Prototype Reveal

Students will combine their research, math, and AI-assisted designs to create a final physical or 3D digital prototype of their 'Smart Crop Guardian.' This guardian is not just a garden; it's a system. The prototype must demonstrate how it uses data to protect crops and maximize yield to help the community achieve Zero Hunger. They will present their 'Guardian' to the Chef from the entry event.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Build or digitally model your garden layout, including features like rainwater collectors, 'smart' sensor locations (represented by markers), and specific crop zones.
2. Create a 'Data Dashboard' display for your prototype that shows the climate data and math calculations that informed your design.
3. Prepare a 2-minute pitch explaining how your design ethically uses AI and local data to provide food for the community.

Final Product

What students will submit as the final product of the activityA physical 3D model (using recycled materials) or a detailed 3D digital model (using CAD software) of the 'Smart Crop Guardian' garden, accompanied by a pitch presentation.

Alignment

How this activity aligns with the learning objectives & standardsAligns with all standards, specifically Research Synthesis and Science (designing a method to minimize environmental impact).
