Output

In this activity, students will build a simple circuit using an LED light, a battery,
a resistor, and a switch. When the switch is activated, the LED will light up,
demonstrating how electricity travels through the circuit to power the light.

This hands-on activity helps students understand how electronics, such as
lights, function in everyday life.

Concepts

Electricity and Circuits: Students will discover how electricity moves

through a circuit to make devices like lights work. The battery supplies the
power, and the LED lights up when the switch is turned on. This is similar to
how lights and toys in our homes function

The Purpose of a Resistor: The resistor controls the flow of electricity to

the LED, ensuring it does not receive too much power. This protects the LED
from burning out and teaches students that sometimes we need to reduce
the energy in a circuit to keep things safe.

Observations

While doing the “Creating a Working Circuit” activity, students will observe
the following:

The LED lights up when electricity flows through the completed circuit.

The resistor ensures the LED receives the right amount of energy to operate
safely.

The switch controls the electricity, turning the light on or off.

Application

Home Lighting Systems: The

circuit they create is similar to
the way lights in our homes work.
The switch in their circuit mimics

a light switch those controls
whether the light is on or off.
