Nonrenewable Resources

Nonrenewable Resources

Nonrenewable resources are natural materials that cannot be replaced quickly once they are used up. These include fossil fuels like coal, oil, and natural gas, as well as minerals like copper and gold. They formed deep in the Earth over millions of years from ancient plants, animals, and geological processes. Because they take so long to form, they are limited in supply. Learning about nonrenewable resources helps us understand how human activities affect Earth’s systems and why it’s important to use energy wisely and look for alternatives.

Science and Engineering Practices (SEP): Asking Questions and Defining Problems

Scientists and engineers study nonrenewable resources by asking questions like: How much is left? How is it being used? What problems can happen if we use too much? They also define problems like pollution, land damage, and climate change caused by using these resources. By thinking critically and asking your own questions, you can better understand how nonrenewable resources impact the environment and explore ways to reduce our dependence on them.

Activity Ideas:

• Resource Debate – Discuss the pros and cons of using coal, oil, or natural gas and consider what would happen if we ran out.
  
• Fossil Fuel Footprint – Track how much energy is used in your home or school and consider how much comes from nonrenewable sources.
  
• Problem-Solution Poster – Identify an environmental issue caused by a nonrenewable resource and design a poster showing ways to solve or reduce the problem.
  

Crosscutting Concept (CCC): Cause and Effect

The use of nonrenewable resources often leads to environmental changes. When we burn fossil fuels for energy, we release greenhouse gases into the air, which trap heat and change the climate. Mining for minerals can destroy habitats and pollute water. By understanding the cause-and-effect relationships, we can see how our actions have long-term consequences on Earth’s systems.

• Cause: Burning coal for electricity
  Effect: Releases carbon dioxide, contributing to climate change.
  
• Cause: Drilling for oil in the ocean
  Effect: Risk of oil spills that harm marine life.
  
• Cause: Mining for metals
  Effect: Can remove vegetation and pollute soil and water.
  

When we connect what we use to what happens in nature, we can make smarter choices and help protect Earth’s future.
