Give Me A Holler

INGREDIENTS

2 Tennis Balls
Tennis Racket

I INSTRUCTIONS
STEP 1: Using the tennis racket, hit one of the tennis balls, without making a noise.

STEP 2: Make observations of the tennis ball to provide evidence that a pattern can be used to predict the future motion of the ball.

STEP 3: Using the tennis racket, hit the other tennis ball, this time, make an intense noise, while hitting the tennis ball.

STEP 4: Make observations of the tennis ball to provide evidence that a pattern can be used to predict the future motion of the ball.

EXPLANATION
The tennis ball hit while making an intense noise will go a greater distance. Engaging your lungs and your trachea or windpipe can give you more power. Some scientists say, this allows you to concentrate and causes a surge in adrenaline, allowing you to apply more force, increasing the speed of the ball, and causing the ball to go a greater distance.
