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 element symbol?Dy
2. What is the atomic number?66
3. Why do electric cars need Dysprosium?Dysprosium is added to the magnets in electric‑car motors. It makes the magnets stronger and keeps them working well when the motor heats up. This helps the car run smoothly and efficiently.
4. How does Dysprosium help wind turbines?The big magnets that spin wind‑turbine generators use Dysprosium to stay powerful. With Dysprosium, the magnets keep working even at high temperatures, so the turbines can produce clean energy reliably.
