Four Parts of a Circuit
Ideally, students will have supplies to build their own simple circuits, or alternatively, the teacher will have one set and performance a demonstration for the class. These supplies would include:
-
9V battery
-
battery clip
-
alligator clip wires
-
switch
-
incandescent lamp
Build a simple circuit and allow students see to how all four parts are necessary for the circuit to function.
