Land and Water




What percentage of the Earth is land?
Discuss names of continents and oceans with students.

Use an inflatable globe .


Designate 5 or 10 students as Catchers and position them around the room.


Assign an equal number as Markers. They record


name______


Land ____ Water ____


on the classroom board.


Assign other students as Checkers. They will verify if the Catchers right thumb is on land or water.

Toss ball to first Catcher.

The
Catcher and Checker tell the Marker whether the Catcher's right thumb is on land or water.


The Catcher tosses the globe to the next Catcher.

After 10 tosses you will have recorded 50 or 100 catches. This will give you an estimate of how much of the Earth is covered with salt water.
