Getting to Know the Components

Now test your knowledge by building a circuit.

• Interactive activity: Build a simple circuit with just a battery, LED, and wire.

Optional: With a more advanced kit try building a series circuit with a switch and resistor.

Learn more! Do your research to find out what is a resistor, LED, battery, switch, and wire?

Exploring Simple Circuits

• Open vs closed circuits (What happens when a circuit is broken?)
• How does a switch work? (On/Off in a circuit)

Hands-on project: Create a basic circuit with a light that turns on and off using a switch.

Series vs Parallel Circuits

• What’s the difference between a series and parallel circuit?

Activity: Compare two circuits, one in series and the other in parallel, and see how they affect the LEDs.

Learning About Resistors

• What do resistors do in a circuit?

Activity: Use different resistors to control the brightness of an LED.

You are correct if you said resistors limit the flow of current. That is one way engineers use Math in electronics. Resistors have different values measured in Ohms. The higher the value the dimmer the light bulb.
