We explore how the electric energy is coming into our houses and we realize that electric energy has a big cost, i.e. not only the cost of the energy that we consume but also there is an environmental cost for the Earth. Therefore is crucial for every country to replace electric plants that operate with fossil fuels with renewable energy sources such are photovoltaic systems or wind turbines. Unfortunately, climate change is here and we have to take actions in order to change it.
Teachers: Mario Di Fonza in collaboration with Sabrina Nappi, Riccardo Di Pietro, Rosanna Busiello
Age: 14-16 years old. February-march
Let’s start with some questions!
Which kind of lamps can we buy after the old incandescent bulb, invented by Edison, has retired? Which are the energy-efficient light bulbs and which ones emit less CO2 in the environment? Which parameter helps us understand how much light a light bulb really emits? How much money can we save using led lamps compared to incandescent lamps? How long can we keep the incandescent lamp on? How long does it take to pay back a led purchase? Students will learn different types of light bulbs on the market in order to know the consequent energy and money savings.
This activity could be introduced on April 22nd, “Earth Day”, a celebration ofthe environment and the protection of the Earth.
We chose Inquiry Based Science Education (IBSE) methodology in which research is the most important task of pedagogical approach because it encourages students to ask questions and develop actions to solve problems and understand phenomena.
