    In this lesson, students will learn about the transformation of kinetic and potential energy to electricity, the major energy sources including fossil fuels, and the importance of fossil fuels. Students will also understand that the transition to new energy sources is a long and slow process.\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    This lesson starts with a simple demonstration and students brainstorming what energy can we use to rotate the turbine to generate electricity. Then, students will learn about how engines and thermal power stations work. An important part of the lesson is for students to learn about how hydropower and wind power stations transform kinetic and potential energy to electricity. After a quick introduction to a variety of\u00a0energy sources, students will work in groups to explore the three types of fossil fuels: what are they? Why are they important? How are they used? Students will also learn about energy use from a historical perspective: the change of energy sources is a slow and long process, and that\u2019s why we cannot immediately give up using fossil fuels.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

                There are three sections in the article: coal, oil, and natural gas. Divide your class into three groups. Each group will be assigned to read one type of fossil and fill in the corresponding column on Page 3. After the group work, ask two students to stay at the table, other students go to the other tables to learn about the other two fossil fuels. They will need to bring back now knowledge learned at the other tables and share it with their groups.<\/p>

                Note:<\/strong> Direct your students’ attention to the first paragraph of the article.<\/p>

                Read the graphs about the global energy consumption and energy consumption in the US and in Israel. Emphasize that fossil fuels are our major energy sources.\u00a0<\/p>

                \u00a0<\/p>

                Ask students:\u00a0<\/p>

                • Do you think that fossil fuels have always been the largest energy source?\u00a0<\/li>
