Speakers...and other things

We have made so many different experiments so far such as, testing batteries, lighting lightbulbs, learning about circuits, generating motors and making speakers. We have learned about parallel circuits which is electricity with multiples for the electricity to travel, and series circuits with one path for electricity to travel and it can use a switch. We also learned that there are 4 different ways to light a lightbulb. The switching of the wires between the positive and negative and then touching the battery to the foot of the lightbulb or the silver, metal ring. We made DC motors and learned about the energy, the magnet and battery that are all connected. Once the wire ring starts moving, the energy from the battery and electrons make it keep spinning. But most recently we have made speakers. We used 2 paper plates, magnets, wire, notecrads, and glue. We wrapped wire and 2 strips of paper around the magnet. We glued it all in place and then pulled the first piece of paper and the magnet out. Glue the magnet to the back of one plate and the wire coil to the back of the other plate. Then make the cards into accordions and glue them to each plate so the plates are glued together. The magnet needs to be sure to slip in and out of the wire coil to create vibrations. The wires need to stick out of the sides of the plates so they can be sanded down so the wires can connect to alligator clips and the amp that plays the music. The magnet, wire and clips all connect together to make the sound and create the speaker.
