Electricity is our focus this week! We will look at what electrical energy is, how and what it needs to travel, and ways that it can make things happen. I have attached many readings, some worksheets, notes, and even intervention materials used this week. I will update the notes as we take them.
Electrical energy is charged particles. When these charge particles move as a current in a circuit ( path) we can use it!
Resources relating to electricity:
CURRENT
The FLOW of energy ( think of the flow of cars in traffic, or of water through a river)
CIRCUIT
The actual PATH, the road or driveway, that the electric CURRENT( flow of electrical energy) travels along.
Circuits need:
---An energy SOURCE ( where the electricity comes from, usually a battery or a wall outlet)
---WIRES to travel along ( wires are made of conductors such as copper or another metal, but are covered in an insulation such as rubber or plastic to stop people from shocking themselves)
---an object that uses the electricity to PRODUCE other forms of energy ( for example, a fan that uses electricity to turn and produce mechanical energy)
SOMETIMES CIRCUITS DON'T WORK!!!
This is called an OPEN or INCOMPLETE circuit.
It can happen because:
a bulb has burned out
a battery is dead or there is no source
because a wire is not connected!
COMPLETE or CLOSED circuits allow electricity to travel to where is needs to be.
ELECTRICITY CAN CHANGE INTO OTHERS FORMS OF ENERGY!
----A microwave is plugged into the wall. Electricity travels through the wires to the microwave. The microwave then uses the electricity to create thermal energy, mechanical energy, light energy, and even sound energy!
