Stephanie and Javier wanted to find out what type of baseball bat would hit the ball

farther. Javier thought that a metal bat would hit the ball farther, while Steven

thought the wooden bat would hit the ball farther. The coach said, “Let’s find out

who is right.” The coach had each boy hit 50 balls with the metal bat and 50 balls

with the wooden bat every day during practice for five days. Each day both boys

hit the ball farther using the metal bat. “Ha, ha,” said Javier, “a metal bat does hit

the ball farther.”

Match the word to the answer.
