Electricity & Energy Transformations
What is Energy?
The Definition:
Energy is the ability to do work or cause a change in matter.
Electrical Energy:
The movement of electrons (tiny particles) through a conductor.
Stored vs. Moving
Potential Energy
Energy that is stored and ready to be used.
Example: A battery sitting on a shelf.
Kinetic Energy
Energy in motion.
Example: Electricity flowing through a wire to a lightbulb.

Light/Heat Energy
"Energy cannot be created or destroyed, it only changes forms."
Energy at Home
Kinetic to Electric
Wind turbines turn movement into electrical energy.
Electric to Mechanical
A mixer turns electrical energy into motion (spinning).
Electric to Thermal
A toaster turns electrical energy into heat.
Quick Check
If you turn on a flashlight, what energy transformation is happening?
Discuss with your neighbor!

Invisible Forces & Attraction
What is a Magnet?
A magnet is an object that creates an invisible force called magnetism.
Key Characteristics:
Has two poles (North & South)
Attracts certain metals (Iron, Nickel, Cobalt)
Can pull or push without touching

"The magnetic field is the area around a magnet where its force can be felt."
The closer you are to the poles, the stronger the force!
Magnets Everywhere
Navigation
The Earth itself is a giant magnet! Compasses use it to find North.
Technology
Computer hard drives and credit cards use magnetism to store data.
Electricity
Spinning magnets are used in power plants to create electricity!
Magnetic Challenge
If I cut a bar magnet in half, do I end up with one North piece and one South piece? Or two smaller magnets with both poles?
Make your prediction!

Building the Flow
The Complete Loop
An electric circuit is a closed path that allows electricity to flow from a source to a device and back.
Essential Ingredients:
1. Power Source: Battery or Outlet
2. Conductor: Wires
3. Load: Lightbulb, Motor, Speaker
4. Controller: Switch (Optional)
The Path
Closed = ON | Open = OFF
Type 1: Series Circuit
The Single Lane
All components are connected in a single path. Electricity has only one way to go!
The Problem:
If one bulb breaks, the whole circuit fails (like old holiday lights).
BATT
Everything shares the flow!
Type 2: Parallel Circuit
The Multi-Lane Highway
Electricity has multiple paths to take.
The Benefit:
If one bulb breaks, the others stay lit! This is how your house is wired.
Each branch is independent!
Can it Flow?
Conductors
Materials that allow electricity to flow easily.
Copper Aluminum Water
Insulators
Materials that block or resist the flow of electricity.
Rubber Glass Plastic
Circuit Lab
We are going to use batteries, wires, and bulbs to build our own working circuits!
Let's get connected!

Part 2: Build & Compare
1. Series Circuit
Draw a circuit with one battery and two lightbulbs in a single loop.
Question: If you unscrew one bulb, what happens to the other?
2. Parallel Circuit
Draw a circuit with one battery and two lightbulbs in two separate paths.
Question: If you unscrew one bulb, what happens to the other?
Part 3: Conductors vs. Insulators
Test three classroom objects by placing them in your circuit path. Do they let the bulb light up?
