Richland High physics students observe how a 50 gram weight extends the length of a spring. The students added mass in 50 gram increments and measured how far the spring extended in each instance.

"Students are learning about graphical analysis and proportions," explains teacher John Bittinger. "In this lab, the extension of a spring is directly proportional to the mass applied. Students graph their data to discover a direct proportion. Later in the unit, we'll apply this knowledge of Hooke's Law to more complex scenarios - like bungi jumping."
