Tuesday, February 16, 2010 Oceans: Earth Ball Catch Beg, borrow,
steal or buy an inflatable globe or other spherical
representation of the Earth that can be tossed around the
classroom. Have students throw the globe to one another around
the room. When a student catches the globe, he/she should look
to see if his/her left thumb is on water or land. The student
will call out "land" or "water" and the teacher (or another
student) keeps a tally of land and water catches on the board.
At the end of the game, analyze the data and you should find
that about 70% of the time, the student's thumb was on water. A
great introduction to a study of oceans and water - emphasizing
the large percentage of the Earth that is covered with water.
