Weeks 10,
11, and 12 make up a three-week cycle about water. Currently, you are
in Week A: Teacher As Researcher.
This week you should
refer to the resources listed under Readings & References, and you
need to complete the assignments listed under Assignments & Rubrics.
This week’s assignments focus on…
|
Individual:
- Doing an
activity with your students.
- Catch
a Globe: How Much of Earth Is Covered with Water
- Evaporating
Water: Now You See It, Now You Don't!
- Freezing
Water: Ice is Nice
- The
Proportion of Water on Earth That Is Fresh
- Posting
reflections about what students learned from the activity.
- Responding
to teammates' reflections.
- Suggesting
criteria for effective concept-building activities.
Team:
- Developing
criteria for effective concept-building activities and the learning
and teaching strategies that make them work.

Readings
& References
Read:
Earth seems to have a lot of water. In fact, 75% of the planet is covered
by water. Since water is everywhere (even in the deserts), and all life
requires water to be alive, it can be considered the circulatory system
of Earth. Not only is "food" for life on Earth obtained from
water, but water also provides the solution to transport nutrients to
and within living organisms. The unique characteristics of water as a
universal solvent and its behavior when changing states seem almost counter
intuitive and even miraculous.
Water is deposited
on (or moved to) dry land because of the "water
cycle." Water is a major contributor to shaping the lithosphere
and also provides energy to drive the atmosphere. Further investigation
reveals, however, that in spite of this apparent limitless resource, Earth
does not really have much water as a percentage of its total volume (a
3-foot diameter model of Earth would have only one cup of water). Thus,
water is actually relatively very scarce.
In this three-week
cycle, you will explore liquid water as a big part of Earth, and in the
next three-week cycle, you will explore Earth's atmosphere. Through participation
in both cycles, you will develop experiences needed to recognize and understand
the water cycle and its interaction with other spheres as an Earth dynamic.
