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 material composition?Primarily unvulcanized rubber, characterized by high plasticity and tackiness
2. What is the erasure principle?Operates via adhesion and absorption, lifting pigment particles into its matrix
3. How does a kneaded eraser lift pencil marks?Its sticky surface grabs loose graphite, charcoal, or pastel particles and pulls them into the eraser instead of wearing away the paper.
4. Why is a kneaded eraser gentler than a regular eraser?It uses adhesion instead of friction, so it doesn’t scrape or damage the paper, making it safe for delicate drawings.

Unvulcanized rubber: A polymer that retains flexibility and tackiness, crucial for its absorptive properties.
Plasticity: The inherent ability of a material to deform permanently and retain its new shape.
Subtractive drawing: An artistic method involving the removal of material to create form and light.
Pigment particles: The microscopic grains of color material (like graphite or charcoal) that form a drawing.
