Learning Objectives

  • 1. Associate the physical quantities to their respective units of measure
  • 2. Know the various ways of obtaining electric energy
  • 3. Understanding the relationships between the social process and the evolution of technologies
  • 4. Recognize the materials and wastes used in the production and consumption system and how they can be assimilated by ecological systems

Guiding Ideas

The activities began by means of a conversation wheel in which the students should raise hypotheses about how the electric energy arrives in their houses. Then graphs and tables were analyzed on simple attitudes that can save electrical energy. With this data, the students systematized the information, made records and solved exercises about how the electricity bill is calculated by the company that provided the service.

Later, the students analyzed the map of the planet Earth and identified which are the most common energy matrixes in Brazil and in the World. They found that in 2016 the Brazilian energy matrix was divided into 66% hydric, 19% fossil, 5% wind, 9% biomass and 1% nuclear.

Student Activities

The teacher created a world in the creative mode and the students entered this virtual environment with the goal of building a hydroelectric plant. They used the game's own chat to communicate about the best strategies for finishing the project.

First they dug the river bed and raised the banks with blocks of earth forming small plateaus. Then they put blocks of water to fill the open hole. Part of the students built the river while others built the ciliary forest with fauna and flora. When they finished, they all focused on dam construction, piston placement, and redstones to simulate water movement.

 

Performance Expectations

Students should describe the energy transformations involved in each stage of electricity generation and realize that the potential energy of the water stored in the dam is transformed into kinetic energy, moving the turbines and being transformed into electrical energy in the generator.

They should also understand why it is necessary to form large dams for the operation of a hydroelectric plant and how it can impact the environment
