    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.

                                                                            Introduction to Electronics and Circuits  49
