Electric Circuits

What was the point of this activity?
Demonstrate electrical circuit during a series and parallel circuit.
•Explain how you would introduce this to your class.
 First, we will learn about the different types of circuits. I will use the electrical circuit simulator to demonstrate each circuit and how the number of bulbs affects a series and parallel circuit.

•Where do you see a student having difficulty with this?
 -Understanding why each circuit result is different while using the same amount of bulbs.
-Confusing the different circuits with each other.
•What changes or extensions could you do to this activity?
-allowing students to guess what occurs if the circuit is connected to the parallel and series circuit
– Allow students to use more than 3 bulbs and observe what happens during each electrical circuit.
Scientific Principles:
Series circuits appear dimmer because they have a lower voltage that is being dispersed throughout each bulb. While in a parallel circuit, the voltage is not shared between each bulb. Each bulb will have the same amount of voltages; this allows the lights to be the same level of brightness. In a parallel circuit, the light bulbs are placed on a separate branch line while a series circuit is placed along the same branch.
