PROBLEM: What is the difference between a parallel and series circuit?

PREDICTION:

PROCEDURE:

Follow the diagrams below and compare a series circuit with a parallel circuit. Then use your classmates and an alien ball to make your human series and parallel circuit. The electrons flow through the surface of your body, so in fact you act as a wire.

1. How many paths of current does the series circuit have? 
     
2. How many paths of current does the parallel circuit have? 
      

Draw how you made your series and parallel circuit with your classmate. Use stick figures to represent students.

CONCLUSIONS:  
Explain the difference between series and parallel? 

Which one do you think is used in our society? Explain.
