Introduction

Hello, this article Teaches you

• tell the difference between a conductor and an insulator
• why a wire has both a plastic covering on it and a strip of medal
• Describe the transfer of energy in a circuit made of wires bulb,and a battery
• Describe the charges of a rubbed balloon and a object that is attracted to it
• Describe a electromagnet
• draw of make a circuit which contains battery wires a switch, and a light bulb
• identify parts of a atom
• identify electricity in household objects
• what a open and closed circuit is

conductors and insulators

a conductor is a material that lets electricity flow through it a insulator is a material that stops electricity from flowing a wire has plastic wrapped around the wire so the electricity doesn't jump to you (your a conductor by the way) and shock you or burned for example:

Describe the transfer of energy in a circuit made of a battery, wires, light bulb

in a closed circuit, the transfer of energy begins with the battery which changes chemical energy begins with the battery which changes chemical energy into electrical energy. the wires are transport for the electrical energy.the light bulb changes the electrical into both heat and light.

describe the changes of a rubbed balloon and the object that is attracted to it

a rubber balloon has a negative charge it has gained electrons from the the object that was rubbed on it. since opposites attract, the object that is attracted to the ballon a positive charge

describe a electromagnet

an electromagnet is a temporary magnet that is created when electricity flows in wires coiled around a iron bar. electromagnets are created when electric circuits produce magnetic field

make a basic circuit

let's make a circuit that lights up a light bulb it's pretty simple: make sure the wire is touching the light bulbs metal part. and make sure the bulb is touching a conductor --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- you could also add a switch like this ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

draw and label an atom

atoms should include protons(positive charge) and neutrons(neutral) in the nucleus(center of the atom) with electrons(negative) on the outer rings For example,

identify the energy transfer that occurs in household objects

here is a example of some household objects:

• a iron converts electrical energy to heat
• a buzzer electrical energy to sound
• a lamp converts electricity into heat and light

• open and closed circuits

  a open circuit is a circuit that has a gap that prevents electricity from flowing. A closed circuit is a circuit with no gaps so electricity will flow through
