Step 5 Attach a connecting wire from the negative of led to the resistor.

Output

In the Sunshine Indicator activity, students will create a simple circuit that

uses a Light Dependent Resistor (LDR) to detect sunlight. When the sunlight
shines on the LDR, it will cause an LED to light up, indicating the presence
of sunlight. This hands-on project helps students understand how light can

control electrical devices.

Concepts

In the Sunshine Indicator activity, students will create a simple circuit that
utilizes a Light Dependent Resistor (LDR) to detect sunlight. When exposed
to light, the LDR decreases its resistance, allowing electricity to flow and

illuminating an LED.

Observations

During the Sunshine Indicator activity, students will observe:

The LED lights up when the LDR is exposed to sunlight or bright light from
the torch.

When the light source is removed or the brightness decreases, the LED turns

off.

The switch allows them to turn the circuit on and off, providing control over
when they want to test the LDR’s response to light.
