Introduction
Introduction:
We have already learned about
- What electricity is
- Electrical charges
- Static electricity
- Current electricity
Today we will be learning to create our our Electrical Circuit and understand how electricty affects us everyday.
Task
Students will view the video https://www.youtube.com/watch?v=VnnpLaKsqGU
Next students will pretend that they are electricians and they have been hired to fix an electrial circuit that is not working and teach the homeowners about electricity costs.
Process
Our newly appointed electricians will begin to understand more about their job and how to do it.
Materials You Will Need:
- Wire that is already attached to battery holder
- Light bulb holder
- Small light bulb
- Battery holder
- D size Battery
- Paperclip
How to Build a Simple Complete Circuit:
1. Gather all materials.
2. Set the battery aside. Take the battery holder and attach the red wire to one contact point on the light bulb holder and the black wire to the other contact point on the light bulb holder.
2a. Optional: If you would like to use a switch, attach the switch to the middle of the red wire or use a paperclip.
3. Place the small light bulb inside the light bulb holder. Screw it in.
4. Put the battery inside the battery holder if you are not using a switch. As soon as the battery is in tight, the light bulb should light up since there is a complete electric circuit
5. Make sure the switch is in the off position if you are using one. Place the battery inside the battery holder and turn the switch on. The light bulb should light up since there is a complete electric circuit.
Remember when the circuit switch is open, the current does not flow to the bulb. If you used a switch, press down on the switch (paperclip) with your finger. By doing this you are closing and completing the circuit so the electricity can flow to the bulb.

Evaluation
Answer each of the following questions to test your comprehension.
What does the battery do?
The battery supplies the power.
What do the wires do?
The wires transport the electricity from one place to another.
What does the light bulb do?
The light bulb uses the electricity to provide light.
Conclusion
Conclusion:
Today we learned about electrical circuits and hopefully who much it costs to run all of it.
Science is FUN!!
