Step 6 See the result.

Output

In this Laser Beam Light Circuit activity, when the push button is pressed,

the battery powers the LED, which emits a focused beam of light resembling a
laser. The resistor controls the current flow, ensuring the LED is protected from
excess current. The magnetic board helps connect and hold the components in

place.

Concepts

1. Current Control and Resistance: You will understand how resistors help
regulate the flow of electricity through the circuit, preventing the LED from

being damaged by too much current. This introduces the concept of electrical
resistance and its importance in circuits.

2. Light and Electronics: The activity demonstrates how electrical energy is
converted into light energy using an LED, linking to the concept of energy

transformation in science.

Observations

In the Laser Beam Light Circuit activity, students will observe how pressing
the button completes the circuit and powers the LED to emit a bright beam of

light. They will see how resistors play a role in controlling the current, ensuring
