Grade and Content Area: 8th Grade – Physical Science —


Participate in a home run derby challenge while learning the concept of velocity along the way. Three difficulty levels are provided by the game. Easy throws slow pitches down the middle, Medium slightly increases the pitch speed and allows the ball to be thrown anywhere in the strike zone, Hard throws the ball very fast all over the strike zone and even allows for curve balls. Once the difficulty level is selected, six of the best home run hitters in baseball history are given as character options.

Lesson Plan

Description of the Science Content of the Module: Velocity Park will provide plenty of practice for velocity problems in an interactive and fun way.  The students use their knowledge of unbalanced forces in the everyday activity of baseball to connect force and velocity.

When it is most appropriate to use the Module: This game is designed to be played once the concept of velocity / speed has been introduced. Students should be familiar with rounding and long division.

Game Play: Velocity Park gives the user 15 total pitches. Pitches are hit by aligning the cross-hair with the ball on the screen and left-clicking with the mouse. If the user is successful, the ball will be hit. Some hits will simply be ground outs, resulting in a low amount of points. Other hits will be fly outs and home runs. Points are awarded based on the distance of the hit. Bonus points can then be earned by calculating the velocity of the ball. A successful calculation (rounded to the nearest tenth) will earn the user 150 bonus points, while an incorrect velocity will cost the user 25 points (to discourage not calculating the velocity).

National Science Education Standards: Physical Science – Standard B

  • The motion of an object can be described by its position, direction of motion, and speed. That motion can be measured and represented on a graph.
  • An object that is not being subjected to a force will continue to move at a constant speed and in a straight line.
  • If more than one force acts on an object along a straight line, then the forces will reinforce or cancel one another, depending on their direction and magnitude. Unbalanced forces will cause changes in the speed or direction of an object’s motion.

Ohio Content Standards: 8th Grade Physical Science Standards #2, #3

2. Explain that motion describes the change in the position of an object (characterized by a speed and direction) as time changes.

3. Explain that an unbalanced force acting on an object changes that object’s speed and/or direction.

Comments from STEAM Teachers: “Velocity Park was the most popular game that my students played.They enjoyed the competitive challenge of the game."
