1. This bundle is compiled of three labs assesing student knowledge on potential energy. BALL BOUNCE LAB:Students explore how the drop height (GPE) of a ball affect the bounce height (KE) of the ball. They compare dropping a ping pong ball vs. a golf ball at varying heights.CAN CRUSH LAB:This resource

Students explore elastic potential energy by determining the relationship between the distances a slinky connected to a four wheel cart is stretched and the speeds in which the four wheel cart travels.

Materials Needed: Halls Cars, Slinky, Meter Stick, Stopwatches

NGSSMS-PS3-1
Construct and interpret graphical displays of data to describe the relationships of kinetic energy to the mass of an object and to the speed of an object. Emphasis is on descriptive relationships between kinetic energy and mass separately from kinetic energy and speed. Examples could include riding a bicycle at different speeds, rolling different sizes of rocks downhill, and getting hit by a wiffle ball versus a tennis ball.
NGSSMS-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. Emphasis is on relative amounts of potential energy, not on calculations of potential energy. Examples of objects within systems interacting at varying distances could include: the Earth and either a roller coaster cart at varying positions on a hill or objects at varying heights on shelves, changing the direction/orientation of a magnet, and a balloon with static electrical charge being brought closer to a classmate’s hair. Examples of models could include representations, diagrams, pictures, and written descriptions of systems. Assessment is limited to two objects and electric, magnetic, and gravitational interactions.
