This electricity starter pack combines a vocabulary list with a quiz and a note-taking guide to reinforce key concepts from the video. The quiz assesses students’ understanding of how electricity is produced and measured, while the vocabulary list defines essential terms like nucleus, proton, electron, and electromagnetic force.
Instructions: Answer the prompt provided by your teacher.
Instructions: Watch the Introduction to Electricity video and listen for the vocabulary words.
| Word | Definition | Example |
|---|---|---|
| Atom | noun; the smallest building block of matter, with a center called a nucleus, surrounded by electrons | “Atoms, of course, are tiny building blocks that make up every substance in the universe.” |
| Substance | noun; a kind of matter made up of atoms, which can be solids, liquids, or gases | “Atoms, of course, are tiny building blocks that make up every substance in the universe.” |
| Positive Charge | noun phrase; a type of electric charge, which happens when something has more protons than electrons | “In the center of every atom is a nucleus with a positive electrical charge.” |
| Electron | noun; a tiny, negatively charged particle that moves around the nucleus of an atom | “Around [the positively charged nucleus] are electrons with a negative charge.” |
| Negative Charge | noun phrase; a type of electric charge, which happens when something has more electrons than protons | “Around [the positively charged nucleus] are electrons with a negative charge.” |
| Electromagnetic Force | noun phrase; a kind of force that happens between objects with electric charge, that can either pull together or push apart | “Positive and negative charges attract, and it’s this electromagnetic force that holds the atom together . . .” |
| Gravity | noun; the invisible force that pulls all objects toward one another | “. . . it’s this electromagnetic force that holds the atom together – sort of like [how] gravity holds planets in orbit around the Sun.” |
| Orbit | noun; the oval-shaped path an object takes as it moves around another object | “In some things, electrons bounce randomly from one orbit to the next.” |
| Charged Particle | noun phrase; a tiny piece of matter that has a positive or negative electric charge | “Remember that electrons are charged particles. They’re essentially like super tiny magnets . . .” |
| Electricity | noun; a form of energy that comes from the movement of charged particles, especially electrons | “Electricity happens when we get electrons to line up and all flow together.” |
| Ampere | noun; a unit used to measure electric current – how much electricity is flowing per second | “To get one ampere of electricity requires over six quintillions of [electrons] all flowing per second.” |
| Quintillion | noun; a number that is a 1 followed by 18 zeros – 1,000,000,000,000,000,000 | “To get one ampere of electricity requires over six quintillions of [electrons] all flowing per second.” |
Instructions: Circle the correct answer based on what you learned in the Introduction to Electricity video and then fill in the blanks using the word bank.
Q1. What do we call the positively charged center of an atom?
Q2. What is the force that holds atoms together?
Q3. How do we make electrons move to produce electricity?
Q4. To generate one ampere of electricity, how many electrons per second must flow?
| ampere | electricity | electrons | magnets |
| negatively charged | nucleus | positively charged |
_________________________ is the flow of many tiny particles called _________________________ that flow from the orbit of one atom to another. Inside every atom is a center called the _________________________, which is _________________________. Around the nucleus are electrons that are _________________________. To make electrons flow in one direction, we usually use _________________________, which can push or pull electrons. The amount of electricity flowing is measured in a unit called an _________________________.
