Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the scientific classification?Strike Termination Device / Air Terminal
2. What is the primary function?To intercept lightning strikes and conduct electrical current safely to the ground
3. What is a lightning rod and why does it help protect buildings?A lightning rod is a metal stick placed at the top of a building that gives lightning a safe path to the ground. It helps stop fires and damage by letting the electric current flow into the earth instead of through the building.
4. How does a lightning rod work?Lightning wants to travel the easiest route to the ground. The metal rod is very conductive and is the highest point, so the spark starts there and goes straight down through a wire into the earth.

Impedance: The total opposition to alternating electric current, including resistance and reactance.
Atmospheric Electricity: Electrical phenomena occurring in the Earth's atmosphere, such as lightning and static charge.
Conductor Cable (Down Conductor): A wire or strap that carries lightning current from the air terminal to the ground.
Grounding Electrode: A conductor buried in the earth to provide a low-resistance connection for electrical current dissipation.
