Eco-Engineers: Designing the Sustainable Cities of Tomorrow

Grade 5ScienceEnvironmental Science5 days

In this environmental engineering project, fifth-grade students are tasked with designing and building "Resilience City," a sustainable urban model capable of surviving a simulated future power crisis. Students research renewable energy sources, analyze geographic constraints, and apply the engineering design process to create a 3D model featuring green spaces and carbon-neutral infrastructure. The experience culminates in a professional presentation where students defend their design choices using scientific evidence to promote local environmental protection.

Standards & Learning Goals

Learning Goals

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

Explain the concept of urban sustainability and identify how specific green technologies contribute to a reduced carbon footprint.
Compare and contrast different renewable energy sources (solar, wind, hydroelectric) and justify their placement within a city model for maximum efficiency.
Apply the Engineering Design Process to brainstorm, prototype, and refine a physical or digital model of a sustainable city.
Analyze the relationship between urban planning and environmental health, specifically focusing on the role of green spaces in supporting biodiversity and air quality.
Present and defend city design choices using evidence gathered from research on environmental science and engineering principles.

Entry Events

Events that will be used to introduce the project to students

The 2075 Blackout Broadcast

Students enter a darkened classroom to see a simulated 'Emergency Broadcast' from the Year 2075. A frantic mayor explains that the old power grid has permanently failed due to fossil fuel depletion, and the students are the lead architects recruited to build 'Resilience City'—the world's first fully self-sustaining urban center.

📚

Portfolio Activities

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

Activity 1

The Power Grid Pro-Con Challenge

In this activity, students evaluate different renewable energy sources (solar, wind, hydroelectric) to determine which are best suited for their city's specific geography. They will create a comparative matrix to weigh the efficiency of each source against the needs of their urban population and the availability of green space. This helps them make data-driven decisions for their model.

Steps

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

1. Research three types of renewable energy: Solar, Wind, and Hydroelectric. Record the environmental requirements for each (e.g., wind needs open space, hydro needs moving water).

2. Analyze a 'City Site Card' (provided by the teacher) describing their city's climate and terrain to determine which energy source is most efficient.

3. Create a rough zone map that balances industrial areas (power plants) with residential green spaces to ensure high air quality.

Final Product

What students will submit as the final product of the activityAn 'Energy Matrix & Zoning Map'—a color-coded chart comparing energy sources and a rough sketch of where these power plants and green spaces will be located.

Alignment

How this activity aligns with the learning objectives & standardsAligns with NGSS 3-5-ETS1-2 (Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria).

Activity 2

Resilience City Rising

This is the hands-on construction phase. Using recycled materials (cardboard, plastic bottles, etc.), students bring their 2D blueprints to life. As they build, they will inevitably encounter structural or spatial challenges, requiring them to iterate—changing their design on the fly just like real engineers. They must ensure that their green spaces are integrated and their energy sources are clearly represented.

Steps

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

1. Gather 'green' building materials from the classroom makerspace or recycling bins.

2. Construct the city's base and major infrastructure (roads, energy plants, buildings) according to the blueprint.

3. Incorporate 'Green Elements'—using moss, green felt, or painted materials to represent parks and carbon-absorbing vegetation.

4. Test the layout: If a building is too far from a green space or the power source looks unstable, adjust the model and note the change in a 'Design Log.'

Final Product

What students will submit as the final product of the activityA physical 3D model of 'Resilience City' built primarily from recycled and sustainable materials.

Alignment

How this activity aligns with the learning objectives & standardsAligns with the 'Developing and Using Models' science practice and the 'Plan and Carry Out Investigations' component of the Engineering Design Process.

Activity 3

The Sustainability Scout Report

To begin their journey as environmental engineers, students must investigate how real-world cities are currently fighting climate change and resource depletion. Students will work in 'Urban Engineering Teams' to research specific sustainable practices such as vertical farming, greywater recycling, and carbon-neutral transportation. This activity builds the foundational knowledge needed to decide which features their own 'Resilience City' must include.

Steps

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

1. Assigned to a team, students use a curated list of digital resources (articles/videos) to find three different ways communities currently protect natural resources.

2. For each method found, students must write down one 'Pro' (benefit) and one 'Con' (challenge) related to implementing it in a large city.

3. Teams select their top three favorite ideas to include in their future city and present their reasoning to the class.

Final Product

What students will submit as the final product of the activityA 'Sustainability Scout Report' featuring a list of three must-have technologies for their city, backed by research facts and citations.

Alignment

How this activity aligns with the learning objectives & standardsAligns with NGSS 5-ESS3-1 (Obtain and combine information about ways individual communities use science ideas to protect Earth’s resources) and CCSS.ELA-LITERACY.W.5.7 (Conduct short research projects to build knowledge).
