[2015] Sarah G (Room 6 Projects): Electricity and Magnetism

Static electricity happens when an item rubs off the outside layer of an atom and gives the item a small negitive charge. When something is being repelled, it is being drawn away. If something is being attracted, it is being drawn foward. An example of static electricity is when you rub your feet across the carpet, a static charge begins to build inside you. Then when you touch something metal, you will feel a small shock.

Electricity And MagnetismBy Sarah

A circuit is a path for electrons to flow through. A closed circuit is a path that allows electrons to flow through. An open circuit is a path that does not allow electrons to flow. For example, if you turn a light off, the path forms a gap that the electrons are not able to cross.

Electric current is created by electric charges. An atom is what makes up matter. Atoms have smaller particles called protons, neutrons, and electrons. Electrons orbit the center of atoms. Protons have a positive charge while electrons have a negitive charge. Protons repel other protons and electrons repel other electrons.

When magnetic forces and electric currents interact with each other, it creates an electromagnet. One way to make an electromagnet is to wrap a wire around an iron nail then put the two ends of the wire on a battery. Then you can use paper clips to see the magnet in action!

In a parallel circuit, there is more than one way for electrons to flow through. In a series circuit, there is only one way for the electrons to flow.

A conductor is an object that is still able to allow the electrons to flow through the wire. An insulator is an object that blocks the electrons from flowing trough the wire. An insulator can also be a coating over the wire that protects you from electricity.

You might not know it, but we use electromagnets in our daily lives! Two examples of elctromagnets that we use in our daily lives is doorbells and loudspeakers. Doorbells have electromagnets because when you ring the doorbell, an electromagnet is connected to an electric circuit. Loudspeakers use an electromagnet because the sound that comes out of the speaker comes from an electromagnet.
