Introduction to the Electric Grid – Starter Pack
Summary
This electric grid vocabulary worksheet builds the core language students need to understand how electricity is generated and delivered. Students watch the Introduction to the Electric Grid video while defining key terms and completing a quiz and cloze notes that reinforce the main concepts.
This starter pack is part of the full Electric Grid lesson plan. Use this after the bell ringer and before the data set activity.
Key concepts students learn
- What the electric grid is and what it does
- How generators produce electricity in power plants
- Why voltage is stepped up for transmission and stepped down for safe use
- What substations, transformers, operators, and regulators do
How to use it
- Use as direct instruction with guided notes
- Assign the quiz for a fast check of understanding
- Use cloze notes for differentiation or support

Vocabulary
Instructions: Watch the Introduction to the Electric Grid video and listen for the vocabulary words.
| Word | Definition | Example |
|---|---|---|
| Generator | noun; a machine that converts mechanical energy into electrical energy | “Ninety-nine percent of the electricity for homes, schools, buildings and factories is made in power plants by generators.” |
| Transmit | verb; to send or carry energy or signals from one place to another | “Then it’s transmitted across a massive network we call the electric grid.” |
| Electric Grid | noun phrase; a network of power plants, wires, and equipment that distribute electricity to homes and businesses | “Then it’s transmitted across a massive network we call the electric grid.” |
| Voltage | noun; the force that pushes electric current through a wire or circuit | noun; the force that pushes electric current through a wire or circuit “The generator makes electricity, which gets stepped up into extremely high voltage . . .” |
| Power Lines | noun phrase; wires that carry electricity over large distances from power plants to homes and businesses | “ . . . and then moved across long distances by large power lines.” |
| Distribution Center | noun phrase; a facility in the electric grid that steps high-voltage electricity down and sends it to smaller substations for local delivery | “These go to a distribution center, which steps the voltage down, and sends it out to many smaller substations.” |
| Substation | noun; a facility that lowers voltage from high-voltage transmission lines so electricity can be safely used | “These go to a distribution center, which steps the voltage down, and sends it out to many smaller substations.” |
| Transformer | noun; a device that increases or decreases the voltage of electricity | “Transformers step it down yet again to a household voltage, where it finally goes in your home for use.” |
| Utility Operator | noun phrase; a person or company that manages the delivery of electricity to customers | “This long journey is controlled by utility operators . . .” |
| Regulator | noun; a person or organization that sets and enforces rules for energy systems | “ . . . which are overseen by a regulator.” |
| Quantities | noun; amounts or numbers of something that can be measured | “Remember that electricity can’t be stored in huge quantities, so we have to generate it right when we need it.” |
Quiz & Cloze Notes
Instructions: Circle the correct answer based on what you learned in the Introduction to the Electric Grid video, and then fill in the blanks using the word bank.
Q1. What does the electric grid do?
- Moves electricity from where it’s made to where we use it
- Transforms electricity from high voltage to low voltage
- Balances how much electricity is made with how much is needed at any given time
- All of the above
Q2. What is the primary way electricity is generated for homes and buildings?
- Solar panels on rooftops
- Giant batteries located near cities
- Generators in power plants
- Wind turbines in neighborhoods
Q3. Why are utility operators essential to the functioning of the electric grid?
- They store large amounts of energy for later use.
- They predict electricity demand and manage power generation in real time.
- They build new power lines when needed.
- They repair household wiring.
Q4. What is NOT a part of the electric grid?
- Outlet
- Transformer
- Substation
- Power lines

Electricity is mostly generated in _________________________ by large _________________________, and then carried long distances across the electric _________________________. To travel safely, the voltage is first _________________________ to extremely high levels, and later _________________________ as it gets closer to homes and buildings. Because electricity can’t be _________________________ in large quantities, utility operators must constantly _________________________ how much power people will need, and _________________________ power plants to produce the right amount.
