Product Details

Simple, yet very dramatic. A thin white pine stick is placed over the edge of a table. A sheet of tissue paper is placed over the stick and spread out on the table. When the overhanging portion of the stick is hit sharply with a hammer it breaks. The other end of the stick remains stationary and the paper is not torn. The large surface area of the tissue paper provides 15 psi of pressure resisting the movement of the stick. When struck, the stick cannot withstand the pressure and breaks. Students will be amazed at the results. Enough materials are provided for 10 demonstrations.

Concepts: Air pressure, surface area, inertia.
Time Required: 20 minutes
Note: A hammer is required, but not included.

Performance Expectations

MS-PS1-1: Develop models to describe the atomic composition of simple molecules and extended structures.
MS-PS1-2: Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
MS-PS3-2: Develop a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the system.
HS-PS2-1: Analyze data to support the claim that Newton’s second law of motion describes the mathematical relationship among the net force on a macroscopic object, its mass, and its acceleration.
