Instructions: Watch the Science of Electricity video and listen for the vocabulary words.
| Word | Definition | Example |
|---|---|---|
| Silicon | noun; A natural element from sand and rocks that can act as a semiconductor, used in electronics and solar panels to help turn sunlight into electricity. | “This [way] uses silicon – like in a computer chip – to turn light into electricity.” |
| Computer Chip | noun phrase; a tiny electronic part typically made of silicon that processes or stores information in computers and other devices | “This [way] uses silicon – like in a computer chip – to turn light into electricity.” |
| Generator | noun; a machine that converts mechanical energy into electrical energy | “The other 99% comes from generators.” |
| Copper | noun; a metal that easily conducts electricity and is used in wires and motors | “A generator is just magnets surrounding a core of coil wire, usually copper.” |
| Coil | noun; a loop or series of loops of wire, often used in electric devices to create a magnetic field | “The coil turns within the generators and makes electricity…” |
| Turbine | noun; a machine that spins when water, air or steam flows through it to generate electricity | “Water makes steam, and steam turns the turbine.” |
Quiz
Instructions: Circle the correct answer based on what you learned in the Science of Electricity video.
Q1. According to the video, 99% of the world’s electricity is produced using which of the following?
- Silicon
- Copper wire
- Generators
- Solar
Q2. Which of the following correctly shows the sequence of how heat is used to generate electricity, according to the video?
- Silicon chips heat up in sunlight; a turbine transfers heat to boil water; steam produces electricity.
- Heat boils water to make steam; steam turns a turbine, which runs a generator to make electricity.
- Sunlight heats silicon chips; silicon chips produce steam; steam turns turbines to make electricity.
- Copper coil heats up in sunlight; a turbine transfers heat to boil water; steam produces electricity.
Q3. According to the video, what percentage of the world’s electricity comes from water flowing through a dam (hydropower)?
- 4%
- 24%
- 16%
- 58%
Q4. Which of the following lists common sources of heat used by large power plants to generate electricity, according to the video?
- silicon chips, coal, or nuclear
- natural gas, copper wire, or coal
- coal, natural gas, or nuclear
- sunlight, silicon chips, or geothermal
