X-Raying the Hydrosphere – Diagnosing Water Problems

Introduction

Radiologic Technologists are trained to look beyond the surface and diagnose problems using imaging techniques such as X-rays, CT scans, and MRI. In this activity, you will apply your diagnostic thinking skills to environmental science by treating the Earth’s hydrosphere (all water systems) as a “patient.”

Water systems around the world face serious problems such as pollution, flooding, contamination, and climate change effects. Just like diseases affect the human body, these issues weaken and damage the hydrosphere.

Through this WebQuest, you will creatively analyze a water-related problem and visualize it as a radiologic image.

Task

Your task is to:

  1. Choose one water-related problem.

  2. Create a drawing that represents the problem as if it were an X-ray, CT scan, or MRI image.

  3. Include labels and a short diagnosis explaining the problem.

  4. Present your work and suggest possible “treatments” (solutions).

Final Product:

  • A labeled diagnostic-style drawing

  • A short written explanation (1–2 paragraphs)

  • A brief class presentation

Process

Follow these steps:

Step 1: Select a Topic

Choose one:

  • Water pollution (plastic, chemical, oil spill)

  • Ocean acidification

  • Groundwater contamination

  • Flooding and erosion

  • Climate change effects on water systems

  • Waterborne diseases (e.g., cholera, dysentery)

Step 2: Research the Problem

Use the provided websites (see Resources section) to:

  • Understand the causes

  • Identify effects on humans and ecosystems

  • Find possible solutions

Take notes.

Step 3: Plan Your “Diagnostic Image”

Imagine the hydrosphere as a human body.

Decide:

  • What body part represents your chosen water system?

  • How will the problem appear in an X-ray-style image?

Sketch your idea before final drawing.

Step 4: Create Your Artwork

  • Draw a clear X-ray/scan-style illustration.

  • Use labels.

  • Make it creative but scientifically accurate.

Step 5: Write the Diagnosis

Include:

  • Description of the problem

  • Why it is harmful

  • Possible treatments/solutions

Step 6: Present and Reflect

  • Explain your drawing.

  • Share your “diagnosis.”

  • Discuss solutions like a medical treatment plan.

 

Resources

Use the following reliable educational websites:

  • United Nations Environment Programme – Water and Pollution Resources

  • World Health Organization – Waterborne Diseases Information

  • National Geographic Society – Ocean and Environmental Science Articles

  • U.S. Environmental Protection Agency – Water Pollution and Groundwater Information

(You may also use other credible educational or scientific websites.)

Conclusion

Through this WebQuest, you explored environmental issues in a creative and professional way by applying radiologic diagnostic thinking to real-world water problems. By visualizing the hydrosphere as a patient, you strengthened your analytical skills, environmental awareness, and problem-solving abilities.

Radiologic Technologists play an important role in healthcare, but understanding global health issues such as water safety and environmental sustainability is equally important. Reflect on how diagnostic thinking can be applied beyond the medical field.
