Thirsty Thursday Activity:
How Much H20 on Campus?

---

Florida has an average of over 50 inces of rain each year. How many square inches of rain falls on our campus in an average year?

Example: Lake Alfred Middle School covers 37.5 acres.

1 acre=43560 square feet
1 sq ft=144 square inches
so 1 acre=6272640 square inces of land

this means that Lake Alfred Middle School has:
6272640 x 37.5 acres=235224000 square inches of land

235224000 x 50 inches of rain=11761200000

The amount of rain that falls on Lake Alfred Middle School in an average year is 11761200000 square inches.

Once the students have calculated the amount of rain, they can discuss where it all goes, supporting their ideas with details.

From this lesson plan out of the Florida Geographic Alliance's Geography Awareness Week November 12-18, 2000 packet, Donna Ellis and Mary Ellen Adlam came up with this activity.
