What Should I
Measure?
The manager or the Chicago Cubs has
asked you to find out which travel farther after they are
hit by a bat, cold baseballs or warm baseballs.
How can you use the listed materials
to answer that question?
First decide what needs to be measured
and how you can gather all the data you need.
Here are some things to keep in mind
as you plan:
- To conduct the experiment
efficiently, people need to be assigned jobs to
do. Some of the jobs are obvious (batter,
pitcher, catcher, outfielders). Other jobs are
less obvious. Think about what other jobs can be
assigned to make everything run
smoothly.
- Marking off the field in
some way will make measuring the flight of each
hit go faster.
- Keep the cold baseballs
in a container with ice but don't let them get
wet.
- Keeping the batter from
knowing the temperature of the ball should be
easy.
- Keeping the pitcher from
telling a warm ball from a cold ball is almost
impossible.

How could you use a batting tee to
make this a double-blind experiment?
