4. Contextual (cultural) elements
The development of practical applications of electricity marked a new phase in industrial activity in the late 19th century.
Electric energy, which in principle was another form of energy, at the time when steam was at its peak, eventually prevailed thanks to its great versatility: it was an energy that was easy to generate, transmit, apply and control.
In addition, electrical energy can be obtained from various sources and can be used for a wide variety of uses, from lighting to heat generation or movement.
5. Cognitive (thinking) processes
Relate the effects of electrical energy and its conversion capacity in other energy manifestations. Know how electricity is generated and transported, describing how schematically the operation of the different renewable and non-renewable power plants.
Design, build and control technical solutions to simple problems, using mechanisms and circuits.
Know and assess the environmental impact of the generation, transport, distribution and use of energy, promoting greater efficiency and energy savings.
6. Methodology
Organization and class distribution / timing
To impart all these contents I will apply an active and participatory methodology, in which the students are made the protagonists of the teaching and learning process.
The development of these activities will be carried out in different groups of students, so we will work in a way:
- individual
- in pairs
- Small group
- the class group
This unit is developed in 8 sessions
Resources / Materials
-materials collected in my technology symbaloo
-Exercises and materials from the class book
-circuits that we will use in practice
