Activity 3B: Snapback! Exploring Elasticity Lab

Students will investigate Hooke's law by studying the elastic properties of various sized tubing, especially the relationship between a force that stretches an elastic body and the length the elastic body stretches. Students will apply a known force to several elastic tubes and measure resulting changes in the diameter and length. Once students acquire a basic understanding of elasticity, they will relate this concept to the cardiovascular system.

Objectives: 
  • Investigate the properties of elastic bodies
  • Measure how changes in force may affect the amount of extension (stretch) in an elastic body
  • Distinguish between extension (strain) and force of weight (stress)
  • Provide a definition of Hooke's law
  • Apply the principle of elasticity to human blood vessels
