See if they can connect it into the circuit to make the light come on and off. Discuss how electricity flows. Again, each pair must draw what they have done. This completes the thinking process and makes the learning more personal. Electrical motors can also be added.
Students enjoy making small fans out of the motors.
Each pair of students can exchange their light bulb and socket for a small electric motor and try to connect it into the circuit. Torn or cut paper makes great fan blades. Let the students experiment to find the best size and shape to make the fan go very fast. The role of the teacher in this activity is to be a facilitator. Please refrain from your urge to teach.
