Topic Overview
Quick Facts
Water is key to all life on Earth. The oceans
occupy over 317 million cubic miles.
Humans rely heavily upon potable water from
rivers. Earth has about 300 cubic miles of river water.
Texas’
Gulf Coastal region is over 300 miles long.
Nearly 500 species, including neotropical
migratory birds, shorebirds, raptors, and waterfowl, can be found along the
last 275 miles of the Rio Grande River Valley.
South Texas is home to over 300 species of
butterflies.
Balmorhea State Park, located in west Texas is
home to a rare desert wetland.
Artesian wells in the west Texas desert are home
to many unique speices and even allow recreational scuba diving.
Caddo Lake State Park in northern Texas, near
the Louisiana border is home to one of the most spectacular wetlands in Texas.
Begin the Lesson
When you think of aquatic environments in Texas,
what environments can you name? Rivers, lakes, wetlands, marshes and the Gulf
of Mexico should come to mind. These are the subject of our lesson
– those regions and the animals found within. An interactive map that you might
wish to use at various points of the introduction can be found at:
http://www.traveltex.com/TexasMap.aspx Whole Class Introduction to the Lesson
You will need at least one
computer with Internet connectivity and a projection device, a classroom with
more than one computer, or access to a computer lab. This introduction will
take approximately 10 minutes to complete.
Present pictures of several aquatic environments in Texas
to the learners.
(several images can be found on: http://www.texasexplorer.com/) Ask them to identify what each can be classified as (a river, lake, marsh/wetlands, or Gulf Coast). Discuss the difference between each and the importance of each to humans. Sample Questions:
Where does the water originate that flows across
Texas? Answers will vary but the
learners should realize that the oceans are the ultimate source of water on
this planet and water is recycled to the land by the water cycle.
Which way do the rivers flow in Texas?
Can you prove it? The rivers flow towards the Gulf of Mexico.
What characteristics might an animal living
in/near water in northern Texas
have from an animal living in Gulf of Mexico waters near
Brownsville? The animal living near
Brownsville must be adapted to salt
water. The animal living in Northern Texas must be
adapted to fresh water and to greater annual temperature variations.
As part of the introduction, you may want to review some of the
glossary terms in advance of students going online. At this point you can
launch the WebLesson as whole-class activity using a projection device, or you
can assign students to work individually or in teams in a computer lab.

Introduction From the western high plains and prairies to the Gulf Coast and the coastal wetlands, Texas is a large and biologically diverse state. The pages that follow enable you to explore the river systems that carry water across the state, the kinds of life found within and along those rivers, and how conditions change as one approaches the brackish and salt waters found along and near the coastline. The coastal region is also dotted with extensive wetlands. Wetlands are marshy regions that host a wide variety of life forms, including animals that live there year-round and migratory birds that spend their winters in the Texas coastal wetlands and then migrate north in the Spring. The lesson ends with an opportunity to learn about the impact of the recent floods seen across much of the state and the long-term effects of these floods.
Scenario You are a journalist for a national science magazine. You are on an expedition in Texas chronicling aquatic life across the state. What aquatic animals are dominant in the interior? What animals are found near or along the coastline? Watch for opportunities to create journal entries as you take a virtual journey across the state of Texas.

Travel Texas - Gulf Coast
http://www.traveltex.com/Region.aspx?ID=4 Conclusion & Project
Conclusion Texas is home to literally thousands of miles of surface water. The water is as varied as conditions across Texas. Freshwater rivers dominate in Texas higher elevation interior. As land elevations decrease, the rivers flow towards the coast. Large segments of several Texas rivers are threatened by various pollutants. Texas can be divided into several regions, each with its own characteristic climate and surface environment. Aquifers are found in the middle of the state. Aquifers contain highly adapted species to this unique environment. Within about 50 miles of the coast, the land flattens out and extensive wetlands occur. Near the coast, interaction between tidal forces and flowing river waters results in the formation of brackish waters in the form of brackish wetlands or estuaries. These wetlands are home to many varied species from shrimp to catfish.
Project Study your journal entries; create a summary that describes how conditions change from west Texas and the panhandle region to the Gulf Coast region. Identify specific species found in each region. Describe how they are adapted to their environment.

Differentiated LearningHere are some projects that can be used after the students have
completed the online assignment or as a complement to your lesson. The students
can use any media deemed appropriate for the project. Each has been recommended
with specific student groups in mind.
AS-All Students
GT-Gifted/Talented
ESL-English Second Language
SN-Special Needs
Individual and Group Projects
Select a river system and create a poster
describing all aspects of it. SN, ESL
Create a powerpoint presentation illustrating
all aspects of a river system, include members of the community and how they
interact. AS, GT
Create a picture food web that exists within a habitat
found within a river system, wetland region or in the Gulf of Mexico.
Identify the kinds of interactions between the organisms and label these on the
food web. AS, ESL, SN
Select a river system, wetland region or the Gulf
of Mexico and identify the endangered species found within that
biome. Report on actions being taken to protect those species. AS
Prepare a report detailing the environmental
issues being faced in a biome of your choice. Identify possible solutions to
those environmental issues, including those currently being employed by local,
state and federal governments. AS, GT
Final Activity – Whole Class
For each Texas region identified on page three of the lesson,
select one species and prepare a poster that includes a picture of the species
you selected. Write about that species’ ideal habitat including what it eats
and what eats it. Write a brief summary describing how it is well suited to the
region in which it lives. The learner should then present their poster(s) to
the class.
To complete this project, the learners will need Internet
access and will need to know how to search the web for information. Encourage
students to use digital libraries such as the National Science Digital Library
(www.nsdl.org) A printer should also be
available. Each poster will likely require between at least 30 minutes to
prepare. If time is a consideration, break the learners into small teams and
have each take ownership of one region.

Quiz Questions & Answers
Project
Study your journal entries; create a summary that describes how conditions change from west Texas and the panhandle region to the Gulf Coast region. Identify specific species found in each region. Describe how they are adapted to their environment.
Rubric
Excellent (30 – 20)
An excellent student response meets all the project requirements and demonstrates that the student absorbed key lesson concepts and gave them thoughtful consideration. The response shows original thinking, creativity, and a strong sense of purpose. Ideas are organized and clearly articulated according to the proper conventions of writing (at this grade level).
Satisfactory (20 – 10)
A satisfactory student response meets most of the project requirements but overlooks one or more important elements. It reflects a general understanding of the key lesson concepts but shows little depth. The response shows little creativity or originality. Ideas are somewhat disorganized and difficult to follow, and there are numerous grammatical and mechanical errors.
Needs Improvement (10 – 0)
The student response is perfunctory, showing little or no effort. It is unclear if the student thought about or even read any of the lesson content. Ideas are scattered or off-topic. If possible, ask the student to revisit the lesson with a peer or mentor and then rewrite his or her response. |
