Lesson II: The Hydrosphere: Water Location, Distribution, Quantity
Introduction:
Water is continually moving around, through, and above the Earth
as water vapor,
liquid water, and ice. In fact, water is continually changing
its form. The Earth is pretty much a "closed system," like a terrarium.
That means that the Earth neither, as a whole, gains nor loses
much matter, including water. Although some matter, such as meteors
from outer space, are captured by Earth, very little of Earth's
substances escape into outer space. This is certainly true about
water. This means that the same water that existed on Earth millions
of years ago is still here.
Objectives:
At the end of this lesson, the students will be able to answer
the following:
- Where is the
Earth's water located?
- How is Earth's
water distributed?
- How much water
is there on (and in) the Earth?
- How much water
is useable by humans?
- What is the role of the
ocean in climate changes?
- What is the connection between
clouds and climate?
- Can k-6 lesson
plans related to lesson be developed from NC Standard Course of Study?
Activities:
- Students will
study information on the website:
http://ga.water.usgs.gov/edu/earthwherewater.html.
- Each cooperative
learning group will present information learned from research
that answers the above queries.
- Students will
share related lesson plans and units found that can be used
in elementary
classrooms (grades K-6).
- Students will
review and demonstrate knowledge learned from the following
NASA websites by developing hands-on activities for K-6 lesson
plans:
