Week 1: Introduction to Sustainable Cities
Learning Objectives Understand the concept of sustainable cities. Identify global urban sustainability challenges. Form project teams and select a specific problem to address.
What Makes a City Sustainable? Key factors : Energy, waste management, transportation, water, green spaces. Examples of sustainable cities worldwide (e.g., Copenhagen, Singapore). Grades 4-6 Grades 7-9
What does Sustainable Cities Mean? Protecting the Earth: Sustainable cities use energy that doesn’t harm the environment, like solar energy from the sun. They also reduce waste by recycling and planting more trees to keep the air clean and healthy. Saving Resources: These cities try to use things like water and electricity carefully. For example, they build homes that stay warm in winter and cool in summer, so people don’t have to use too much energy. Healthy and Safe Living: Sustainable cities make sure people are healthy by offering places to walk, ride bikes, or use buses and trains instead of always driving cars. This helps reduce air pollution and makes the city safer for everyone. Fair for Everyone: In sustainable cities, everyone should be able to live in a home, go to school, and have access to healthcare. These cities try to make sure no one is left out, no matter how much money they have. Environmentally Friendly : Sustainable cities are designed to reduce pollution and waste. This means using clean energy (like solar or wind power), recycling, and making sure there is less trash. Cities might also have more trees, parks, and green spaces, which help the environment and make life better for people. Resource Management : A sustainable city uses its resources wisely. This means saving water and energy, building homes and buildings that are good at keeping heat in (to save energy), and making sure food and resources are used without waste. Healthy Living : These cities make sure people live healthy lives. For example, there may be good public transportation so people don’t need to drive cars, which helps reduce air pollution. There are also places for people to walk or bike, keeping them active. Affordable and Fair : Sustainable cities care about all people. This means making sure that everyone can live there, no matter how much money they have. There should be enough homes for everyone and easy access to schools, health care, and jobs. Grades 4-6 Grades 7-9
Project Kick-off Group formation. Problem selection: Brainstorm global/local sustainability issues. Key focus: Global challenges (pollution, energy efficiency, etc.)
Homework & Next Steps Answer questions on Sustainable City Worksheet Research sustainable cities Read articles and watch videos on urban sustainability. Prepare initial team ideas for next week’s discussion.
Mastery Check: What Makes Cities Sustainable
Week 2: Research and Problem Definition
Learning Objectives Conduct research on sustainable city solutions. Define and narrow down a specific problem for the project.
How to Research Choose a Topic Pick something you’re curious about or interested in, like animals, space, or your favorite hobby. Ask Questions Think about what you want to learn. Write down questions like “Why?” “How?” or “What?” Find Information Use books, websites, or ask a teacher or parent for help. Make sure the sources are reliable and safe for kids. Take Notes Write down the most important facts. Use your own words to make it easier to understand later. Organize Your Ideas Group similar facts together. You can use a chart, list, or mind map. Make Something With What You Learned Create a poster, write a short report, or share your findings in a fun way, like a drawing or presentation. Check Your Work Make sure your information answers the questions you had. Add more details if needed. Share Your Research Tell a friend, family member, or teacher what you’ve learned. You can also present it to your class!
Activity: Examples of Sustainable Cities Read about the following cities. Choose one city from this list and write a paragraph about why this city is sustainable Vancouver, Canada Renewable Energy: Vancouver was the first big city in North America to plan for 100% renewable electricity. By 2023, it already reached 95%! Eco-Friendly Design: The city uses "eco-density," meaning it builds taller buildings instead of spreading out. This reduces the need for cars and helps save the environment. Olympic Legacy: Hosting the 2010 Winter Olympics inspired Vancouver to start many green projects. These projects still help the city stay sustainable today.
Activity: Examples of Sustainable Cities Winnipeg, Canada Our Winnipeg 2045 vision. This plan focuses on six important areas: Leadership and Good Governance : Making smart decisions to help everyone.

Research Focus Key Aspects of Sustainability: Energy : We need to use clean energy that doesn’t harm the planet. Clean energy comes from sources like the sun, wind, and heat from the Earth. Using this energy helps stop pollution and climate change. Example : Solar panels that use sunlight to make electricity. Transportation : To make cities better for the environment, we need to use transportation that doesn’t pollute. This includes using buses, bikes, and electric cars. Example : Bike-sharing programs where people can borrow bikes to travel instead of using cars. Waste : Reducing the amount of waste is very important. We can recycle things like paper, bottles, and plastic. Instead of throwing everything away, we can reuse and recycle to save resources. Example : Programs that encourage recycling and composting food waste. Water Management : It’s important to use water carefully and not waste it. Cities can save water and make sure it is clean. This helps keep the environment healthy. Example : Collecting rainwater to use for gardens or cleaning.
Group Work R esearch existing solutions (e.g., smart grids, green roofs). Define a clear problem to address. Collect data via surveys, interviews, or secondary research.
Write the Problem Statement State the problem clearly : Explain the problem in simple words so that people can easily understand it. Focus on the main issue that needs solving. Example : "Many people in our community don’t recycle their plastic bottles, which leads to a lot of waste." Describe why the problem is important : Help people understand why the problem matters and why it should be fixed. Example : "This is important because plastic waste can harm animals and pollute the environment." Explain who is affected by the problem : Show how the problem impacts people, animals, or the world. Example : "This problem affects animals in the ocean who can get hurt by plastic waste." Suggest a solution (optional) : While not always necessary in the problem statement, sometimes you can suggest how to begin solving the problem. Example : "We need to encourage people to recycle more so we can reduce waste and protect the environment." Here’s a full example: Problem Statement : "Many people in our community don’t recycle their plastic bottles, which leads to a lot of waste. This is a big problem because plastic waste can harm animals and pollute our environment. If we all recycle more, we can help reduce pollution and keep the Earth clean."
Write your Hypothesis Grade 7-9 Formulate your hypothesis : A good hypothesis predicts the relationship between variables. It often follows this structure: If (cause or change) then (effect or outcome). Example hypothesis : "If plants receive more sunlight, then they will grow taller." Make it testable : Your hypothesis should be something that can be tested with experiments or observations. It should be specific and measurable. Example: "I will measure the height of the plants after four weeks of exposure to different amounts of sunlight." State your independent and dependent variables : Independent variable : What you change in the experiment (e.g., the amount of sunlight). Dependent variable : What you measure (e.g., plant growth). Example Hypotheses: Simple hypothesis : "If I water the plant every day, then it will grow faster." Comparative hypothesis : "Plants grown with natural light will grow taller than plants grown under artificial light." Grades 4-6
Homework & Next Steps Use your research to create a problem statement & Hypothesis on the worksheet . Prepare a project proposal for next week’s review.
Week 3: Ideation and Conceptualization
Learning Objectives Brainstorm and develop potential solutions to address the problem. Create initial sketches or models of your prototype.
Class Activity: Brainstorming Questions to help you brainstorm: What are some things you already know about this topic? What’s a new way to look at this issue? Who might be affected by this issue? How can we improve things? What are different solutions we can try? Grades 4-6 Grades 7-9
Organize Your Ideas Look at all the ideas you wrote down. Are there any similar ideas? Can you group ideas into categories or themes? This will help you see your ideas more clearly. Examples of Categories: Ideas for Action : What can we do? People to Involve : Who can help us? Resources Needed : What do we need? Challenges to Overcome : What might be difficult? Goals : What do we hope to achieve? Group your ideas: Category 1: _________________________________________________ Idea 1: _________________________________________________ Idea 2: _________________________________________________ Category 2: _________________________________________________ Idea 1: _________________________________________________ Idea 2: _________________________________________________
Evaluate Your Ideas Now, look at your grouped ideas. Which ones seem the best? Which ones are most realistic or practical? Which ideas do you think will make the biggest impact? Evaluate your ideas: Which ideas are easy to try? Which ideas need more research or planning? Which ideas would be the most fun? Which ideas might need help from others?
Next Steps After brainstorming, it’s time to figure out what to do next. Choose one or more ideas to move forward with and make a plan. What will you do with your best ideas? Next Step 1: _______________________________________________ Next Step 2: ________________________________________________ Next Step 3: ________________________________________________
Reflection What surprised you during brainstorming? What idea are you most excited to try? Who could you talk to for more ideas or advice?
Prototype Conceptualization Step 1: What is Your Idea?: Step 2: Draw Your Idea: Step 3: What Does It Need? Step 4: Build a Model: Step 5: Test It: Step 6: Make Changes Step 7: Share Your Prototype Grades 4-6 Grades 7-9
Prototype Conceptualization Step 1: What is Your Idea?: First, think about what you want to create. Is it a new toy, a helpful tool, or maybe a new kind of transportation? Example: "I want to create a robot that helps clean my room." Step 2: Draw Your Idea: Once you know what you want to make, try drawing it. This doesn’t have to be perfect, just a simple picture that shows what your idea looks like. Tip: You can draw your idea from different angles, like front, side, or top views. This will help you understand how it works. Step 3: What Does It Need? Think about the things your idea needs to work. What parts will you need? For a toy robot, maybe you'll need motors, sensors, and wheels. Example: "My robot will need wheels to move, sensors to detect dirt, and a motor to make it go." Step 4: Build a Model: Using materials you have, like paper, cardboard, clay, or even Legos, build a simple model (or "prototype") of your idea. This doesn’t need to be perfect—it’s just to help you see how it might work. Tip: You can use things you find around the house to create your model, like boxes, plastic bottles, or even old toys!
Prototype Conceptualization Step 5: Test It: Once you have your simple model, try using it. Does it work the way you thought? If not, don’t worry! You can make changes to improve it. Example: "I tried my robot, but it didn’t move well on the carpet. Maybe I need bigger wheels." Step 6: Make Changes: If something isn’t working the way you imagined, think about how you can make it better. Maybe you need to change the design, use different materials, or add more parts. Example: "I’m going to add stronger wheels to my robot, and make the sensors better so it can detect more dirt." Step 7: Share Your Prototype: Once your model works the way you want, you can share it with your friends or family. Tell them what it does and how it works. You might even get new ideas from them! Tip: You can also take photos of your model and create a presentation to explain your prototype to others. NEXT, Begin conceptualizing possible solutions (e.g., water filtration systems, eco-friendly transportation). Sketch rough designs of the prototype.
Next Steps Use the worksheet to finalize your design concept. Prepare a plan and material list for prototype creation.
Week 4-5: Prototype Development
Learning Objectives Develop a detailed plan for creating and testing the prototype. Identify materials and resources required. Begin building your prototype. Test the prototype for functionality. Make adjustments to the prototype based on testing. Ensure the prototype works as intended.
Detailed Design Finalize your prototype design. Include materials list, tools, and resources needed.
Planning Assign team roles and responsibilities. Project Manager (Organize and lead the team, Keep track of deadlines.) Researcher (Find information and ideas for the project, Share useful details with the team.) Designer (Create the look and plan of the prototype, Decide on materials.) Builder/Engineer (Build the prototype, Test it as it’s being built.) Tester (Test the prototype to make sure it works., Suggest improvements.) Presenter/Communicator (Prepare and present the project, Answer questions about it.) Documenter (Keep track of the project’s progress, Write down important steps and changes.)

Testing and Refining Conduct initial testing of the prototype. Make adjustments as needed based on feedback. Review the prototype and identify any weaknesses. Modify the design as needed to improve performance.
Testing for Feasibility Test the prototype with different variables or scenarios. Collect data on how well the solution addresses the challenge.
Homework & Next Steps Finalize your prototype. Collect any final data to evaluate effectiveness.
Week 6: Data Collection and Analysis
Learning Objectives Collect data through tests and experiments. Analyze the data and determine how well your solution works.
Why is Data Collection Important? Understand the Problem Data helps you know more about a problem. You can see patterns or things that happen often. Measure Success Data shows if your work is helping. For example, it helps compare "before" and "after" results. Make Better Decisions Data helps you choose what to do next based on facts, not guesses. Fix Problems Data shows what is not working. You can use it to improve your ideas or plans. Work Together Teams can share data to understand the same problem and find a solution together. Show Evidence Data makes your work stronger. It proves your ideas are based on facts. Plan for the Future Data helps you guess what might happen next so you can get ready. Example : If you test a project, like a wind-powered car, you can record how fast it goes and if it works well. The data helps you know if the design is good or if it needs fixing.
Common Data Collection Methods Surveys What it is : Asking people questions to get their opinions or ideas. Example : "What is your favorite way to save energy?" Observations What it is : Watching and writing down what happens. Example : Watching how many people recycle in your school. Interviews What it is : Talking to someone and asking them questions. Example : Asking a teacher how they save water at home. Experiments What it is : Testing an idea to see if it works. Example : Testing if solar panels give enough power for a light bulb. Documents What it is : Using information from books or reports. Example : Reading a report about clean water in your city. Social Media or Online Data What it is : Looking at what people share online. Example : Checking how people talk about climate change on Instagram.
How to create survey questions Potential Survey questions examples General Awareness How important is sustainability in your daily life? Do you think our city is sustainable? Why or why not? Transportation How often do you use public transportation, bikes, or walk instead of driving? What improvements would you like to see in transportation options in the city? Energy Use Do you use renewable energy (like solar panels) at home or work? Would you consider using renewable energy if it became more affordable? Waste Management Do you separate your trash for recycling? Why or why not? What changes would encourage more people to recycle in your community? Water Management Do you take steps to save water at home, such as fixing leaks or using water-efficient devices? What do you think are the biggest challenges for managing water in your city?
Data Analysis Tools Use graphs, charts, and tables to analyze your results. Create a graph with your survey questions
Homework & Next Steps Finalize your data analysis. Start working on the final presentation.
Week 7: Presentation Preparation
Learning Objectives Prepare a compelling presentation. Rehearse your presentation as a group.
Simplified Tips for Creating a Display Board Keep it Simple Avoid glitter or extra decorations. Focus only on what is required. Limit Colors Use 2-3 colors. Too many colors can make the board look messy. Follow a Layout Print a board layout to guide you step by step. Use Rubber Cement It’s easy to fix mistakes. If glue leaks, it can be rubbed off. Simple Labels Use clear and easy-to-read titles. Try a template to make your labels neat. Highlight Sections Use colored paper behind your work to make sections stand out. Plan Before Gluing Use tape or putty to check the layout before gluing everything down. Include Good Pictures Show the experiment and supplies. Add pictures of exciting moments. Display Your Work Put your notes and drafts in a folder in front of the board. Judges like to see the work behind the project. Practice Your Presentation Once your board is ready, rehearse explaining it. View Larger
Examples
Tips for a Final Presentation Start with Confidence Greet your audience with a smile and introduce yourself clearly. Stand straight, make eye contact, and speak with a steady voice. Explain Your Project Clearly Start with the problem or question you wanted to solve. Explain your hypothesis, process, and findings step by step. Use simple language to make it easy to understand. Use Visuals Effectively Point to charts, pictures, or sections of your display board when explaining. Make sure visuals support your explanation, not distract from it. Practice Timing Keep your presentation within the time limit. Rehearse to make sure your speech is not too fast or too slow. Answer Questions Calmly Listen carefully to any questions from the audience or judges. If you don’t know the answer, it’s okay to say, “That’s a great question. I’ll look into it!” Show Enthusiasm Be excited about your project! Share why you chose the topic and what you learned. Be Prepared for Feedback Thank the audience or judges for their comments and ideas. Use feedback to improve your future presentations. Stay Organized Bring all materials you may need (notes, prototypes, or folders). Double-check that your display board is complete and neat. End Strong Summarize your findings in a sentence or two. Thank your audience for listening and invite questions.
Week 8: Final Adjustments and Testing
