1. Electricity Learning Targets: Define electron and electricity.
Define contact point.
Create circuits using a D-battery, wire and flashlight bulb.
Explain what is required to allow for the flow of electricity.

2. Lets think about electricity!
Is electricity important?
What are a few things that we use electricity for?
How would the world be different without electricity?

3. Background/Review We know matter is made up of atoms.
Each atom contains protons, neutrons, and electrons.
Protons are positively charged.
Neutrons are neutral.
Electrons are negatively charged.

5. Electrons
If the number of protons in an atom equal the number of electrons then it is balanced. (example = carbon)
Electrons can move from one atom to another making the atoms positively or negatively charged.

6. Electricity
A current of electricity is created when electrons move between atoms.
Electricity is the flow of electrons.

7. Insulators
Materials that want to hold on to their electrons and restrict the flow are insulators.
Examples
Rubber, plastic and wood

8. Conductors
Materials that loosely hold on to their electrons and easily allow the flow of electrons are conductors.
Examples:
Metal(iron, steel, copper), water, people

9. Electrical Circuits

10. Circuits
Circuits are a “bridge” between the negative electrons and the positive atoms.
Connecting a wire to create the bridge allows the flow of electrons from the negative end to the positive end.
Think of a draw bridge.

11. Contact Point
A contact point exists where a conductor (ex. wire) is in contact with another conductor to allow the flow of electrons.
Where were the contact points in your circuits?
Battery-positive and negative ends
Bulb-side and bottom

12. Setting up our SISN 
You will need two pages in your SISN to complete the next part of our class.

13. Circuit Activity
In your bags you have: 3 wires, a D battery, a battery holder, a switch, and a light board.
Arrange these materials in a way that you think you will make the light bulb glow.
Use ALL materials with respect! Do NOT use the materials in an inappropriate way.
When you have made the light bulb turn on, draw what you have done in your SISN.

14. Please get this into your notebook and then we will put one more chart in your notebook.
