For our electrical invention, Kate and I decided to do choice cards. At first we decided on something else but we later decided that it would be too difficult. At the back of the choice cards, two paper fasteners are connected together with an electrical wire. We made a normal series circuit that included: a power pack, electrical wires and a buzzer. The buzzer goes off when the two wires connect with the metal paper fasteners.
Something positive about making the invention is that it gave us a opportunity to showcase what we know. The only negative thing, was that it tested our patience on some occasions. An interesting thing that I noticed was that wiring can be confusing.
