Earth's Surface: Land and Water Percentages
(activity)
Source: Environmental Science Teacher
Purchase giant inflatable globe: $24.95
Have the class
form a large circle. Teacher tosses an inflatable Earth globe to
a student, specifies a hand (L or R), and finger (1-5), and
records whether land or water is beneath that finger. Repeat. 25
tosses should generate enough data to show that 70% of Earth's
surface is covered by water. |
