1 Stored energy in fuels 4 KEY QUESTIONS • What are fuels? • What is needed to burn fuels? • How can we safely burn fuels? • How can we prevent fires and what must we do if there is a fire? 1.1 What are fuels? In Grade 4, we learnt that there are many dierent types of energy. This year we are going to learn about stored energy and how we can use the stored energy to do something useful. QUESTIONS What do you understand by the term fuel? Discuss this word with your partner and write down your own definition below. Learner dependent answer (A material such as coal, gas, or oil that is burned to produce energy) There are a few dierent definitions for fuel. There are three main categories that you can use to investigate fuels. Some fuels can be burnt to create heat and light Wood is often collected and burnt to give us heat and light. On a cold evening it is wonderful to sit around a fire to tell stories and warm yourself with friends.
This man has made afire to keep warm and provide light. 1 Cooking meat on afire made from wood in Khayelitsha. 2 Wood comes from plants, especially trees. When plants are growing, they use the light energy from the sun as well as carbon dioxide and water to grow. Plants take the energy and store it in their leaves, roots and all parts of the plant. Wood also contains this energy stored by plants. Burning wood allows us to change this stored energy into light and heat which is useful to us. Energy from the sun is stored in the tree's wood which is released as light and heat when we burn the wood. Chapter 1. Stored energy in fuels VISIT Formation of fossil fuels (video). goo.gl/y04lH 5
