Good afternoon. This lighthouse is a schoolwork done by Badre, Laura, Valeria and Roberto to show next-year students from Las Canteras how an electrical circuit works with light and sound.

00:00:17,829 --> 00:00:30,829
Our electrical circuit is parallel. It is composed by a cell that supplies electrical energy to the rest of the circuit, through some wires, that act as conductors.

00:00:30,829 --> 00:00:37,460
Apart from this, there are a lamp and a buzzer.

00:00:37,460 --> 00:00:47,799
It also has a one-way switch to turn on the lamp and a push switch to emit the sound.

00:00:47,799 --> 00:00:59,740
We have chosen the lighthouse for our project because it seemed like a very practical and original idea.

idea. The lighthouse is made of foam board, EVA foam, plastic straws and cloth. Our circuit

is a following circuit.
