Hooked on science: give me a holler
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.
