Taking A Global View
students play the same game! (More >>)
Does our Earth have more land or
water? Spin or toss a globe to find out!
you'll need: An inflatable globe
or a spinning globe
or water? If
you have an inflatable globe,
stand in a group. One student should toss the globe to someone
else. The catcher should look at where his or her right-hand index
finger lands. Is it on water or land? Put a
mark on the board in one of those two labeled columns.
(If you have a spinning globe, have one student
spin it, with eyes closed, and move a finger up and down next
to the globe. After 5 seconds, someone says "stop" and
the student puts his or her finger on the globe.)
or water? Your conclusion. After 20 tosses (or spins),
tally your results. What can you conclude
about the amount of land on Earth compared to the amount of water?
(About 75% of Earth's surface is covered with water. Only 25%
is covered with land. What percentages do you get from your numbers?)
is the land? Look down at the Northern Hemisphere from
the north pole (top of the globe). Next, flip the globe and look
at the Southern Hemisphere from the South Pole. Which hemisphere
seems to have more land?
Northern Hemisphere from the North Pole
Southern Hemisphere from the South Pole
