4th Grade Lesson
THE NEW JEDI ORDER

Picture

CONGRATULATIONS!

Your planet fought bravely with the other planets in the galaxy and were victorious in defeating the Empire!  Now, you need to help the new Jedi Order construct light sabers so that they can restore peace in the galaxy.  You are a photonics engineer on your planet.  You have been hired by your planet’s government to help the Jedi construct new light sabers so that they can maintain peace in the galaxy.

Guiding Question

How do toy manufacturers make lightsabers?  

It Is All About Circuits 

In today’s lesson, you will learn how toys are powered with electric circuits.

Terms to Know

circuit:  a complete path around which electricity can flow

open circuit:  a break along the circuit line that causes the current to stop (off)

closed circuit:  when there are no breaks in the circuit line allowing electric current to flow 

conductor:  a material in which electricity can flow through

Light Emitting Diode:  (LED) or a bulb that emits light when energy flows through it

Today's Challenge

You have been given a Lightsaber Construction Kit.  Watch the video below on constructing an LED Lightsaber.  Follow the directions to construct your saber.  Think about what you learned about circuits. 

Reflection

  1. What is the power source in your toy lightsaber?
  2. Describe how the circuit works in your lightsaber. 
  3. Explain what happens with the circuit when you turn your light saber on and off.
