"Science classes are hands down the most important in your education. Make sure to take most of the classes offered and extracurricular activities such as ROV 🤙. You won't retain all of the information shoved at your brain, but the concepts and skills you learn are basically with you forever." -Josiah Rondeau - Class of 2019 The Goal For Today Learn about and experiment with graphing conservation of momentum.

A group of 3rd grade girls involved in the YMCA gymnastics program are trying to discover a way to reduce injuries when they fall off the uneven parallel bars because they know increased force causes increased injuries.
Group 1: This group has named themselves the unicorns and have decided to increase the amount of padding on the uneven bar platform. For their experimentation, they drop a 20 kg weight onto the padding and use a Pasco accelerometer to record the time of impulse as the weight stops. From these trials, they have discovered that for every 10 cm of traditional padding they add, the impact time is increased by .05 seconds. They were then able to apply this discovery to calculate Force of impact.
Group 2: This group is focusing on type of padding. They have decided to use traditional padding, EVOx Memory foam padding, and CTR Type A Ultraboost padding. From their experimentation, they have discovered that 10 cm of traditional padding, EVOx Memory foam padding, and CTR Type A Ultraboost padding provide .05 seconds, .08 seconds, and .03 seconds of of impulse stopping time respectively. They were then able to apply this discover to calculate Force of impact.
Group 3: This group is focusing on how the height of the uneven parallel bars. For their experiment, they dropped a 30 kg weight from 5 different heights (1.0, 1.5, 2.0, 2.5, and 3.0 meters) onto traditional padding and used a Vernier Dual Sense Force Meter to record the force of impulse as the weights stopped on the mats. From this experiment, they learned the force of impact for the heights were as follows: 1 m = 2683 N, 1.5 m = 2906 N, 2.0 m = 3125 N, 2.5 m = 3345 N and 3.0 m = 3601 N .
