Using Marbles to Learn Velocity

Battle High School Math teacher, Justin Burns, took his students outside to calculate the velocity of a marble released at 45 degrees and test their equations.

"We launch marbles at certain angles and measure the time it takes to land and the distance that it travels to calculate the initial velocity of the marble," Burns said.

Then students use the initial velocity and vary the launch angle to get time and distance data for different angles. 

Once the students have several sets of data, they create a model of launch distance as a function of launch angle and test the equations with the ultimate goal of hitting a target 10 feet away. 

"Talk about 100% engagement as everyone had their own role," BHS Math Department Chair Samantha Bratcher said.
