Objective:

Pupils will be exposed to the uses of batteries and bulbs.  Pupils will be able 
to explain the difference between series and parallel circuits. 

Materials Needed:

batteries
bulbs
wire
2 switches
6 sockets
plywood 16"x24"

Strategy:

Pupils will have hands on experience with the batteries and bulbs. They will 
have to make series circuits with one wire and then two wires.  The same will 
apply to a parallel circuit.  The teacher will make two models on the plywood; 
one will consist of three sockets wired together to represent a series circuit. 
The other will also consist of three sockets wired together to represent a 
parallel circuit.  Each will be controlled by their own switches. 

Performance Assessment:

Pupils will be able to light bulbs with the batteries using the different 
combinations.  Also while the teacher holds up the example she/he has made on 
plywood.  Pupils on a sheet of paper will tell the teacher which example is the 
series circuit and which one is the parallel circuit.                       

Conclusions: 
 
Students will have a better understanding of the power of electricity and 
batteries.
