By, Ethan James Dec.6

2. Question
Which ball can I hit the farthest with a bat a baseball, softball, or tennis ball?

3. Background
Why I chose this is because I love sports.I play baseball so I can hit the ball.I was curious which ball would go furthest.I got it from the internet.

4. Hypothesis
If I hit a tennis ball with a bat, it will go the furthest.

5. Variables Independent- I will change the type of ball.
Dependent- Which ball will go the furthest, when hit with the bat.
Constant- The bat.How I hit the ball.How fast the ball goes when pitched.

6. Material Baseball, Softball, Tennis Ball Baseball bat Dad Tape measure
Baseball Field

7. Procedure
What ball can you hit the farthest baseball, softball, or tennis ball.
I will go to baseball field.
I will have my dad pitch.
I will hit the ball.
I will measure with a tape measure and graph it.

8. Data

9. Data The Baseball Averaged 85.6 feet The Softball Averaged 80 feet
The Tennis ball Averaged 83.6 feet

10. Conclusion
Which ball can I hit the furthest with a bat a baseball, softball, or tennis ball.
What I did was I went to baseball field and followed my procedures. I hit each ball three times then averaged them.That was on my data.
What happened is the baseball averaged 85.6 feet.Then I switched to softball. That averaged 80 feet.Then I did the tennis ball.That averaged 83.6 feet.
My hypothesis was wrong.My data showed that the baseball went the furthest.The tennis ball was 2 feet from being more than the baseball.
I learned that a baseball will go further than a tennis ball.I thought it would be the tennis ball.I also learned a lot of mistakes can occur.
Some problems that occurred were the pitch was too low. Sometimes the ball would get stuck in mud.What I would change is i would use a pitching machine. So the pitch was perfect every time.
