Although
humans have Known electricity since ancient times, its applications
were not discoverd until the nineteenth century. Electricity is
essential to modern life and we can see this just by looking around
us. For example, how many times a day do you press a switch to turn
on a light that uses electricity?
Esta
unidad didáctica está dirigida a alumnos de 3º ESO y
la materia de TecnologÃas.
La
unidad que se presenta tiene el objetivo de introducir a los alumnos
en el tema de la electricidad: fundamentos, usos, ventajas y
peligros. Para ello se introducen gradualmente conceptos que permitan
la comprensión progresiva de un fenómeno que no es fácil de
asimilar. Se empezará explicando la naturaleza eléctrica de la
materia a partir de la estructura del átomo, que conducirá al
concepto de corriente eléctrica y al de circuito.
