Stretching Rubber Bands

Stretching Rubber Bands

We can use common household objects to measure properties that match physical laws. This experiment takes a very common household item, the rubber band, and applies physical laws (Hooke’s Law and the Young’s Modulus) to them in a hands-on way.

Themes: Student Projects

Topics: Deformations, Experiments, Hooke's Law, Materials, and Young's Modulus

Grades: 11-12
