5. COR – Minimizing Handle Forces activity* for those unable to do before
   4/3/08 there will be a setup available before the game. See the above
   description of this activity.
6. Finding a Sweet Spot of a bat activity* for those unable to do before
   4/3/08 there will be a setup available before the game. See the above

3. Hustle Award (Hustle Award)
4. Whew! Runner’s speed to first (Whew)
5. Estimated attendance. Students will be asked to predict. Prizes will be awarded for best prediction from each school.
6. Determine/estimate the ball speed off the bat and/or maximum height in air for first base hit in a designated inning. (Students need to know time in air and horizontal distance from home to where ball lands). This determination will be for a designated inning and there prizes will be awarded for best prediction from each school.
7. Work and Power activity (see above description of activity)
