1. What is the distinction?
2. Why does breaking a candy cane make it sparkle?
3. How does triboluminescence differ from other light tricks like piezoluminescence?

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 distinction?Differs from piezoluminescence, which emits light upon deformation rather than fracture
2. Why does breaking a candy cane make it sparkle?Breaking the candy cane creates tiny cracks that separate electric charges inside. When those charges reunite, they release a quick flash of light.
3. How does triboluminescence differ from other light tricks like piezoluminescence?Triboluminescence happens when something breaks or is rubbed, while piezoluminescence is light that comes from squeezing or deforming a material without breaking it.

Mechanoluminescence: The emission of light from a solid material due to mechanical action.
Triboelectric Effect: The generation of static electricity when two materials are brought into contact and then separated.
Charge Carriers: Particles within a material (like electrons or ions) that carry an electric charge.
