Hydroponics: Sustainable Food for Our School

Grade 6Science2 days

In this project, sixth-grade students design and implement a sustainable hydroponic garden at their school to conserve water and provide healthy food options while minimizing environmental impact. Through a series of activities, students research different hydroponic systems, the nutritional needs of plants, and their role in a balanced diet. They create nutritional profiles and meal plans using hydroponically-grown produce, and present their findings, highlighting the science, health, and sustainability benefits of hydroponics. This hands-on project integrates science, health, and environmental education, encouraging innovation and real-world application.

Inquiry Framework

Question Framework

Driving Question

The overarching question that guides the entire project.How can we design and implement a sustainable hydroponic garden at our school to conserve water, provide healthy food options for students, and minimize environmental impact?

Essential Questions

Supporting questions that break down major concepts.

How do hydroponic systems conserve water compared to traditional gardening methods?
What are the key nutrients plants need, and how can hydroponics provide them?
What design considerations are important for a successful hydroponic garden in our school environment?
How can we create a balanced meal plan using the produce from our hydroponic garden?
What are the environmental and economic benefits of hydroponic gardening?

Standards & Learning Goals

Learning Goals

By the end of this project, students will be able to:

Students will be able to design and build a functional hydroponic system.
Students will be able to explain the water conservation benefits of hydroponics.
Students will be able to identify the essential nutrients plants need and how hydroponics delivers them.
Students will be able to design a balanced meal plan incorporating produce from their hydroponic garden.
Students will be able to evaluate the environmental and economic impacts of hydroponic gardening.

Entry Events

Events that will be used to introduce the project to students

A World Without Soil

**Hook:** Imagine a world where water is scarce, but fresh produce is abundant, even in the middle of a city. Could we grow our own food without soil and using minimal water? Present a futuristic video showcasing hydroponic farms in urban settings. **Core Question:** How can we design and implement a sustainable hydroponic garden to address water scarcity and promote healthy eating habits within our school community? **Connection to Standards:** Designing a hydroponic system requires understanding plant needs and nutrient solutions (science). Maintaining a functioning system involves calculating water usage and nutrient ratios. Students will learn how to design balanced meal plans using the produce they grow (health/nutrition). **Engagement:** The futuristic scenario taps into students' imagination about the future of food. The real-world application of building a garden for their school provides a tangible impact and sense of ownership. **Investigation Pathways:** 1. Research different hydroponic systems (e.g., deep water culture, nutrient film technique) and select the most suitable one for the school environment. 2. Experiment with various nutrient solutions to determine the optimal formula for specific plants.

Portfolio Activities

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

Activity 1

Nutrient Investigators

Students will research the nutritional value of different plants suitable for hydroponics. They will select a variety of plants to ensure a range of nutrients in their potential harvest. They will use online resources and nutritional databases to analyze the vitamin, mineral, and macronutrient content of their chosen plants.

Steps

Here is some basic scaffolding to help students complete the activity.

1. Research and select 3-5 plants suitable for your hydroponic system.

2. Use online resources (USDA Food Composition Databases, etc.) to find the nutritional information for each plant.

3. Create a chart or table summarizing the nutritional value of each plant.

4. Write a paragraph explaining how these plants contribute to a balanced diet and which food groups they represent.

Final Product

What students will submit as the final product of the activityA Nutritional Profile Chart for each chosen plant, including key vitamins, minerals, and macronutrients. A short paragraph explaining how these plants contribute to a balanced diet.

Alignment

How this activity aligns with the learning objectives & standardsAddresses the "Design a balanced meal plan..." standard by focusing on the nutritional aspects of the chosen plants and their role in a balanced diet.

Activity 2

Hydroponic Chefs

Students will use the nutritional information they gathered to create balanced meal plans incorporating the produce from their planned hydroponic garden. They will consider portion sizes, dietary recommendations, and different meal combinations to ensure a healthy and varied diet.

Steps

Here is some basic scaffolding to help students complete the activity.

1. Review the nutritional profiles of your chosen plants.

2. Create three balanced meal plans (breakfast, lunch, and dinner) incorporating your hydroponic produce.

3. Specify portion sizes for each meal component.

4. Explain how each meal plan contributes to a balanced diet and provides essential nutrients.

Final Product

What students will submit as the final product of the activityThree sample meal plans (breakfast, lunch, and dinner) featuring the hydroponically grown produce. Each meal plan will include portion sizes and a brief explanation of how it meets nutritional guidelines.

Alignment

How this activity aligns with the learning objectives & standardsAddresses the "Design a balanced meal plan..." standard by having students create meal plans using the plants they've researched.

Activity 3

Hydroponic Showcase

Students will design a presentation to share their hydroponic garden design and meal plans with the class. They will explain the health benefits of hydroponics and how their project promotes sustainable food production.

Steps

Here is some basic scaffolding to help students complete the activity.

1. Compile your research, nutritional profiles, and meal plans.

2. Create a visually appealing presentation showcasing your project.

3. Prepare a script or talking points explaining the science behind hydroponics, the nutritional value of your chosen plants, and the sustainability of your design.

4. Practice your presentation to ensure clarity and engagement.

Final Product

What students will submit as the final product of the activityA presentation (PowerPoint, poster, oral presentation) explaining their hydroponic system, chosen plants, meal plans, and the overall health and environmental benefits of their project.

Alignment

How this activity aligns with the learning objectives & standardsAddresses the "Design a balanced meal plan..." standard. It also reinforces the science aspects of the project by connecting plant growth to human health.
