Hydroelectricity is one of the world’s most popular sources of renewable energy. Not only is it efficient in producing usable power, but it is also relatively clean, safe, and eco-friendly. As a teacher, imparting knowledge about hydroelectricity and its benefits to your students can be an exciting opportunity to stimulate their interest in science, technology, engineering, and math (STEM) subjects. Here are some useful tips for teaching students about hydroelectricity.
Introduction to Hydroelectricity:
Begin by explaining what hydroelectricity is and its workings. Hydroelectric power is electricity generated by the kinetic energy of falling or moving water. Hydropower plants convert the energy contained in moving water into electricity by using electricity generators. Students need to understand the basics of electricity, including electric circuits, voltage, current, and power to comprehend hydroelectric power.
The Science Behind Hydroelectricity:
The concept of hydroelectricity is an excellent topic to introduce students to various STEM fields. In a physics class, for example, your students can learn about water potential energy which is converted to kinetic energy as it flows through turgo turbines. They will learn about how a dam is constructed, how water is controlled through sluice gates, and how turbines work.The impact of gravity on the water flow also forms an essential element in the production of hydroelectricity.
Environmental Impact of Hydroelectricity:
Teaching students how hydroelectricity is obtained plays a huge role in raising awareness about the significance of eco-friendly energy. While it is a clean form of energy, hydroelectricity can also have its negative consequences, like negating aquatic habitats and altering river ecosystems. You can raise topics about the impact of the construction of large dams on economies surrounding the dam site. Introducing such themes will be beneficial as your students can generate ideas on how to make hydroelectricity environmentally friendly.
Benefits of Hydroelectricity:
Hydroelectricity comes with several benefits, among them, being an inexpensive way of generating electricity. It also considerably reduces the reliance on fossil fuels like coal and oil, which are environmentally harmful. Additionally, it is a reliable source of energy that can be harnessed every day of the year, making it a profitable business. Educating your students on these benefits will help them appreciate the importance of hydroelectricity in the global energy market.
