LEVEL 1: Coin Cell

3

Volts

A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work.

THE BATTERY

1.8 - 3.3

Volts

A light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it. LEDs have positive (+) and negative (-) sides to them. For an LED to work it needs to be connected to a voltage source with the correct side.

THE LED

By pinching the two wires coming out of LED on either side of the 3V button cell battery, we can create a circuit by connecting the + side of the battery to the - side of the battery, which results in the flow of electrons through the wires and the Light Emitting Diode.

THE SIMPLEST CIRCUIT

Electrons jumping from atom to atom in the metal (a conductor material) is the flow of electricity.

STUDENTS EXAMPLE

LEVEL 2: SIMPLE CIRCUIT

ACTIVITY MATERIALS

A switch is an electrical component that can disconnect or connect the conducting path in an electrical circuit. Interrupting the electric current turns the LED off, connecting the current turns it on. 

THE SWITCH

An LED circuit requires three basic elements. The light, the wires that create a loop, and a battery. 

A switch can also be added to allow you to open and close the circuit, turning on and off the light.

a switch is an electrical drawbridge when the bridge is up the electrons can't go anywhere

the Light Emitting Diode [LED] will provide our light

the battery holds the electrons

BUILDING A SIMPLE CIRCUIT

Securing the wires to the switch

Attach the metal ends of wires through holes of switch prongs

Secure each side with tape - make sure the wires aren't touching each other!

There is an option to replace wires with copper tape and insert a coin cell on the corner left

Techniques for Paper Circuits

Use folding action to complete the circuit

Lay battery flat and attach copper tape to the top and bottom

Make sure the positive terminal of the LED is connected to the positive terminal of the batter, and vice versa.

LEVEL 3: Motors

To Create a Motor Circuit

Power Supply

(Batteries)

Motor

(Takes electricity and uses it to spin)

Connector

(Conductive Wire)

Connecting the Circuit

Either use crocodile clips

or

if you have a battery pack use the wires to connect the battery to the DC motor

ARDUINO

Arduino Board

Breadboards

Allows you to connect different components together when you need to share things like POWER (5V and GND).

Arduino is a small computer that uses code to tell it what to do, like turning lights on and off.
