Water Challenges in Our World
Water Challenges in Our World
Water is one of the most important resources on Earth. Every living thing depends on it, yet many communities around the world face serious challenges related to water. Some people do not have access to clean drinking water, while others deal with pollution, flooding, or water shortages.
In this project, you will explore real-world water challenges that affect cities and communities. You will think like engineers and problem-solvers by investigating these issues, asking questions, and designing possible solutions.
As you explore each challenge, consider how science, technology, and human decisions all play a role. There is no single “right answer.” Instead, your goal is to understand the problem deeply and develop creative, practical solutions that could make a real difference.
Choose a challenge that interests you and begin your journey to designing a better future.
Clean Drinking Water Access
Clean Drinking Water Access
Challenge
Many communities around the world do not have access to safe drinking water. People may rely on rivers or unsafe sources, which can lead to serious health issues.
Project Idea
Design a low-cost water filtration or purification system that can be used in a small community.
Deep Thinking Questions
What makes water unsafe to drink, even if it looks clean?
How can we design a solution that is affordable for everyone?
What materials could be used if advanced technology is not available?
How would your solution be maintained over time?
Who is responsible for ensuring clean water access in a community?

Water Pollution (Plastic and Waste)
Water Pollution (Plastic and Waste)
Challenge
Rivers, lakes, and oceans are polluted by plastic, chemicals, and human waste. This pollution harms animals, ecosystems, and human health.
Project Idea
Create a system to reduce or collect pollution in water, such as a floating trash collector or filtration barrier.
Deep Thinking Questions
Where does most water pollution come from?
How does pollution travel through water systems?
What are the long-term effects of pollution on ecosystems?
Is it better to clean pollution or prevent it? Why?
How can communities change their behavior to reduce pollution?

Water Waste in Cities
Water Waste in Cities
Challenge
Cities waste large amounts of water due to leaks, overuse, and inefficient systems.
Project Idea
Design a smart system that monitors water usage and reduces waste in homes or cities.
Deep Thinking Questions
Where does most water waste happen in a city?
How can technology help people use less water?
What trade-offs might exist between comfort and conservation?
How can we encourage people to change their water habits?
Should water usage be limited or regulated? Why or why not?

Flooding and Stormwater Management
Flooding and Stormwater Management
Challenge
Heavy rainfall can cause flooding in cities because water cannot drain or be absorbed quickly enough.
Project Idea
Design a system to manage excess rainwater, such as improved drainage, green roofs, or water storage solutions.
Deep Thinking Questions
Why do cities flood more easily than natural environments?
How does urban design affect water movement?
What role can nature play in solving flooding problems?
How can we design systems that work during extreme weather?
What are the social and economic impacts of flooding?

Drought and Water Shortage
Drought and Water Shortage
Challenge
Some regions experience long periods without rain, leading to water shortages that affect people, agriculture, and ecosystems.
Project Idea
Create a system that stores, conserves, or reuses water in areas affected by drought.
Deep Thinking Questions
What causes droughts, and how are they connected to climate change?
How can water be stored effectively for long periods?
What are the most important uses of water during a shortage?
How can communities prepare before a drought happens?
How do water shortages impact food production and daily life?

Water Quality and Testing
Water Quality and Testing
Challenge
Water may appear clean but still contain harmful bacteria, chemicals, or pollutants that are not visible.
Project Idea
Design a simple and effective way to test water quality or detect contamination.
Deep Thinking Questions
What are the most important indicators of water quality?
Why is it difficult to detect some contaminants?
How can testing be made accessible to all communities?
How often should water be tested, and who should do it?
What actions should be taken if water is found to be unsafe?
