The Teacher Guide is available to educators for free download at the following website addresses: Texas Parks and Wildlife: Texas State University: Teacher Guide Description Students are introduced to the wide variety of aquatic ecosystems through science investigations, games, models, cooperative learning activities, Internet projects, readings from the student guides, short videos, science journals, and field based assessments of water quality and environmental conditions in a variety of field trips. Predators range in size from tiny zooplankton to 300 pound alligator gar. Rainfall varies from over 50 inches per year in East Texas to less than 10 inches per year in the west. These photographs in turn inspired an essay by writer Rick Bass that takes him back to his own memories of fog—in the Texas Hill Country and elsewhere. H2O is funded by the , San Antonio.
Grazers feed on the algae. The fast moving water between riffle areas and pools is called a run. The Sabine held a reputation as a haunt for a handful of hunters and loggers, more than a few water moccasins, swarms of mosquitoes, and the occasional black bear lumbering through swamp oak and cypress knees. It is a 12th-order stream when it reaches the Atlantic Ocean.

How can you help marine mammals or sea turtles? With lots of rainfall in the east and north, East Texas streams have more diverse aquatic communities than streams in arid West Texas. Sensitive species are often called indicator species. Each lesson includes an opportunity for students to apply what they have learned by synthesizing the information and demonstrating their learning by developing creative products or performances.

Fish such as shiners have streamlined bodies that allow them to remain stable in currents. Puedes leer cualquier libro en línea o guardarlo en tus dispositivos. Leaves and land insects falling into the water from vegetation on the banks provide organic matter for aquatic food webs.
Activities are designed to be inexpensive and to use the materials that are already in most classrooms. What might you see on a Texas beach? As the plant diversity increases, shredders begin to decrease. New Book Used Book Cheapest Book How long of a rental duration do you need? Streams and rivers contain flowing water. Why is it important to have plenty of plants growing alongside a stream? The presence of pollution sensitive species generally indicates good quality water. Student science journals are also useful for formative and summative assessments.

Covering aquatic science research in education, students and others in attendance were introduced to the multiyear evolution of Texas Aquatic Science. The open-ended questions have many possible answers. Each lesson covers a major subject area and is broken down into short sub-topic video presentations.
They are home to more than 250 species of fish, including about 25 non-native species. The riparian zone is the transition area between the stream edge and the uplands and typically has trees and smaller plants extending outward on either side of the stream. Whiteside Foreword by Fran Gelwick Preface by Andrew Sansom Containing habitat information, physical descriptions, photos, and range maps for more than 150 species of freshwater fishes found in Texas, is an indispensable reference and research tool for ichthyologists, professional fisheries biologists, amateur naturalists, and anglers alike.

Assessment Each chapter provides multiple opportunities for assessment. The plants and animals living in them exist in balance with the processes that recycle nutrients and other aquatic resources essential for life in aquatic communities. Educational Perspective Lessons in each chapter begin with an activity to allow the teacher to assess what students know about the concepts to be studied. The project was conceived in the course of developing means to integrate use of various new mobile and interactive technologies into middle and high school curricula about water from headwaters to the Gulf of Mexico, but researchers heard that to effectively integrate new technology and materials into regular use that there needed to be a context for use. Determined to travel the rest of the river, Ferguson and Botter loaded their gear and launched into the stretch of river that charts the line between the states and ends at the Gulf of Mexico.
Roots help hold the stream banks together, reducing stream bank erosion. For teachers, the Teachers Guide is loaded with science investigations, games, models, cooperative learning activities, Internet projects, readings from the student guides, short aquatic science education videos, science journals, and field based assessments of water quality and environmental conditions in a variety of outdoor education field trips. Certain species of stoneflies, caddisflies and mayflies are sensitive to pollution, as are certain fish and mussels. This first small stream channel is called a first-order stream. Sewage from our towns and cities is cleaned in wastewater treatment plants and often released into nearby streams and rivers.
