Learning about Finite Energy Sources (Primary School)
Objective: This worksheet aims to teach students about finite energy sources, specifically on one example, its properties, uses, and the advantages and disadvantages associated with its use.
Content and methods: The worksheet defines finite energy sources and provides specific examples. It then focuses on one example of a finite energy source, detailing its origin, quantity on Earth, historical use, primary applications, and advantages. Subsequently, it presents its disadvantages, while also highlighting its finite nature. The methods include reading informational texts and filling out a profile for an energy source, followed by questions that prompt critical thinking and class discussion.
Competencies:
- Reading comprehension
- Understanding of scientific concepts (finite energy sources, fossil fuels)
- Analysis of advantages and disadvantages
- Critical thinking and evaluation
- Discussion and communication skills

Learning about Finite Energy Sources (Primary School)
What is a finite energy source?
In this worksheet, you will learn about different types of finite energy sources. But what exactly are they?
Finite energy sources are energy sources that are not available indefinitely. These include, for example, oil, coal, and gas. These energy sources form over millions of years and are eventually depleted when we use them. This means that they do not regenerate or renew quickly. Therefore, it is important to use them sparingly and also look for other energy sources.

Learn more about one type of finite energy sources
Read a text about one type of finite energy sources. Then fill out the profile on the following page.
Coal
Coal is a black or brownish-black rock found deep underground. There are about 1.1 trillion tonnes of coal on Earth. This fossil fuel comes from ancient plant matter that decayed millions of years ago and was buried under layers of soil and rock. People have been using coal for thousands of years, but it became very important during the Industrial Revolution, around 200 years ago.
Coal is mainly used to produce electricity and heat. It is also used in some industries, like making steel. One big advantage of using coal is that it provides a lot of energy, helping to power factories and homes.

Disadvantages of the energy source
As you have learned, using this energy source can have advantages. But can it also have disadvantages? Read the following text, then answer the questions.
The disadvantages of using coal
Source: World Economic Forum
Hello, I'm Daniel Yergin, an energy analyst. Coal is used a lot because it helps generate electricity and power industries. But there are big problems with using it. Right now, burning coal makes dirty air, which can cause health problems like asthma and lung disease. It also releases a lot of carbon dioxide, which leads to climate change and global warming. In the future, coal will run out because it is not endless, and this means we won't have it forever. Also, the pollution from coal will continue to harm the planet, making the air and water dirty. To protect our environment, many people are trying to find cleaner energy sources like wind and solar power. They want to stop using coal to ensure a healthier planet for future generations.
Class discussion
Think about these questions and make notes below:
- Does the use of this energy source have more advantages or more disadvantages?
- Would you support its continued use?
- If yes, why? If no, why not?
Discuss your thoughts in class.
