Sarah's Tennis Ball Launch Experiment

What did Sarah do to test her new slingshot in launching tennis balls? Sarah was trying to see how far her new slingshot would launch tennis balls. She launched all of the tennis balls at the same angle, from the same location, but she did change how far back she pulled the slingshot each trial and recorded the horizontal distance for each trial.

Sarah's experiment with her new slingshot launching tennis balls sounds like a lot of fun! By changing the distance she pulled the slingshot for each trial, Sarah was able to observe how the horizontal distance the tennis balls traveled varied with the pulling distance. This is a great way to test the effectiveness of the slingshot and to gather data on its performance.

It's important in experiments like this to have controlled variables, which in Sarah's case were the size, shape, and color of the tennis balls, as well as the launch angle and location. By keeping these factors constant, Sarah could focus on the impact of the pulling distance on the distance the tennis balls traveled.

Through her observations and recorded data, Sarah was able to determine the relationship between the independent variable - the distance she pulled the slingshot - and the dependent variable - the horizontal distance the tennis balls traveled. This kind of hands-on experiment is a great way to learn about variables and the scientific method in a fun and engaging way!
