Aquatic Communities - Teacher's Guide

   Episode Overview
FrogIn the first segment, Patrice looks at life in lakes, streams, and wetlands. Next Patrice and Dave look at a snapping turtle. Then we take an up-close look at wetlands. Finally, Marissa and Benjamin join biologist Beth Malcolm and help inspect the growth of animal and plant life in a wetland environment.
   Program Objectives
Students will:
1. Will understand that environments support a diversity of living organisms and that they all share limited resources.

2. Describe how freshwater life varies depending on a variety of factors like temperature and water motion.

3. Describe adaptations exhibited by freshwater life.
   Vocabulary
Community
Bog
Wetland
Peat
Evaporation
Fen
Vapor
Swamp
Transpiration
Vernal Pond
   Previewing Activity

Have students name some freshwater communities in their area like lakes, ponds, rivers, streams and marshes.

   Post-Viewing Activities

1. Have students do a "wetland" survey of the school yard. Ask them to identify areas of the school yard that they think will hold water for a short period of time after it rains.

2. Have students research their area and find out what their local watershed is and what issues face it.

3. Using a local map, have students identify local freshwater communities.

   Hands-On:Water Power

In this episode of NatureWorks, students learned about aquatic environments. In this activity students will learn how the movement of rivers can change the landscape.

   Materials Needed

Coffee can and lid
rocks
water
ear plugs (for the teacher)

   Procedure

Divide class into groups of 3-5 students. Give each group a coffee can and lid and a handful of rocks. Place the rocks in the can and fill the can with enough water to cover the rocks. Have each student in the group shake the can for about a minute. After each student has had a turn shaking the can, have students take the lid off and examine the water. Is it still clear or are there now pieces of rock in the water? How is this similar to and different from what happens in rivers.
