basic dribbling/ball handling skills

Suggested Grade Level:


Materials Needed:

soccer balls (roughly one per student), large open area (gym or coned off area outside), whiteboard with pens

Physical activity:


Description of Idea

This game is similar to "Monkey in the Middle." Select 5-6 students (Free Radicals) to start without a soccer ball (electron). Everyone else (stable molecule) will have a ball (electron). As the molecules move throughout the space with their electron, the free radicals try to stablize themselves by stealing (simply touching the ball with their feet) the electron. When they do, they become a stable molecule and the student who loses their electron becomes a free radical.

The object of the game (learning) occurs when the connection is made about too many free radicals or extra antioxidants. The students need to play each way and then have them make the determination of what is happening in the body when there are more or less of the free radicals (antioxidants.)

Elaborate on these topics, depending on your classes' level of comprehension.


You can slowly remove electrons from the game to demonstrate how the body can be greatly affected by too many free radicals, just like the game is negatively affected when few have a ball.

Assessment Ideas:

* Observation of the game and how they follow directions.
* Question and answer period (either informal conversation individually or as a class, or a formal quiz with paper and pencil)

Adaptations for Students with Disabilities:

* Nerf style balls can be used to slow down the ball to make it easier to control the ball.
* Noise-producing balls may be used for vision impaired students.
