Why Fossil Fuels Run Out

About this printable Why Fossil Fuels Run Out science reading passage, NGSS-aligned (Grades 3-5)

This 250-word reading passage introduces fourth-grade students to the concept of nonrenewable energy resources, specifically focusing on fossil fuels. Aligned with NGSS standard 4-ESS3-1, the passage explains why fossil fuels like coal, oil, and natural gas are called nonrenewable resources. Students learn that fossil fuels formed millions of years ago from ancient plants and animals that were buried and compressed over time. The passage emphasizes that because this formation process takes such an incredibly long time, fossil fuels cannot be replaced within a human lifetime or even many lifetimes. Once we use these energy sources, they are gone forever. The reading uses age-appropriate language and relatable examples to help students understand the concept of nonrenewable resources. Audio integration supports diverse learners by providing text-to-speech functionality. Accompanying activities include multiple-choice comprehension questions, writing prompts, and graphic organizers that reinforce understanding of cause and effect relationships and compare renewable versus nonrenewable resources. This educational resource helps students build foundational knowledge about energy resources and prepares them for hands-on investigations and classroom discussions about energy conservation and sustainability.

Sample passage and quiz from Why Fossil Fuels Run Out

Dead plants buried under layers form coal, oil, and gas. — Fossil fuels form underground from buried plants and animals over time.

Fossil fuels are energy sources that formed from plants and animals that lived millions of years ago. The three main types are coal, oil, and natural gas. We use these fuels to power cars, heat homes, and make electricity.

When ancient plants and animals died, they were buried under layers of dirt, sand, and rock. Over millions of years, heat and pressure from the earth changed these remains into fossil fuels. This process took so long that scientists measure it in millions of years, not hundreds or thousands.

Fossil fuels are called nonrenewable resources because they cannot be replaced once we use them. A nonrenewable resource is something that takes so long to form that we cannot get more of it in our lifetime. Think of it like a cookie jar that takes a million years to refill. Once you eat all the cookies, the jar stays empty for your entire life.

Every time we drive a car or turn on lights powered by fossil fuels, we use up some of these resources. Since it took millions of years for them to form, we cannot make more fossil fuels to replace what we use. When they are gone, they are gone forever. This is why scientists and engineers work to find other energy sources that can be replaced, like wind and solar power.
