BENERGY Module 1: Lesson 3

Energy Basics: How Energy Gets from the Original Source to Your Home 

Approximate completion time: 50 min

Lesson Objectives

By the end of this lesson, you will:

  • Traced how energy moves from natural sources (coal, natural gas, solar, wind, etc.) to usable electricity in your home. 
  • Explored the efficiency, reliability, and tradeoffs of different energy sources. 
  • Engaged in inquiry-based questioning, project-based exploration, and a citizen science connection. 
  • Learned persuasion and communication techniques to clearly explain and influence how others perceive energy systems. 

Part 1: How Does Energy Get to You?

Think

Every time you flip on a light in your house, what invisible chain of events had to happen—sometimes thousands of miles away—for that light to turn on? 

Watch

Watch the short video that follows and consider the impact that even a short (25 hour) citywide energy blackout can have on American citizens.

Write

In your notebook, write down your thoughts on where you think energy in your home actually comes from.

  • How does it travel to your light switch? 
  • What parts of this chain are invisible to most people? 

Part 2: What the Heck is the Grid?

Watch – How Electricity Gets to Our Homes (The Grid!)

Discover what the Grid is and how it works.

Create

In your notebook, build a simple flow chart of energy moving from source → generation → transmission → distribution → your home.

Here’s an example:

Part 3: Share What You Know

Share (Citizen Science + Influence Training) 

Students present their flow chart and persuasive “most critical step” to the family or homeschool group. Here are some hints:

  • Speak with authority (clear, confident voice). 
  • Add a story (“Imagine a coal miner digging in Wyoming, and hours later, that energy is making your fridge hum here in Texas…”). 

Extension (Project-Based / Citizen Science) 

  • Research your local electric and natural gas utility: 
  • What percent of electricity comes from natural gas, coal, wind, solar, etc.? 
  • How is it transmitted to your community? 

Part 4: America in the Dark
