PROGRAM OUTLINE (2 HOURS)
This program allows the students to examine the interrelationship between
non-living things, plants, and animals in a pond community. With the
activities in this study, we hope to develop a respect for life, an
awareness of the interdependence of living things and an understanding
of pond food chains.
The program addresses expectations for the strand "Habitats and
Communities". Expectations addressed include-
INTRODUCTION- Food Chain Game
Eighteen wooden signs depicting a variety of pond plants and animals
are scattered throughout the playing area. After the rules of the game
have been explained, students move through the playing area recording
a specific food chain, e.g. plankton, snail, diving beetle, trout. All
the food chains are then recorded by connecting string on a summary board
to construct a food web. This is an excellent game to get students investigating
the interconnectedness of a pond community.
POND VISIT
LIVING COMPONENT- Students use nets to catch a variety of animals that
live in the pond. They are encouraged to look for both vertebrates and
invertebrates. Emphasis is placed on respect and careful handling of
all specimens which are kept in a water tub for observation. Hand lenses
and viewing boxes are used for closer observation. Students use a checklist
with pictures and handbooks to identify their finds. After collecting,
the class is brought together to share special finds.
NON-LIVING COMPONENT- Students measure and record the temperature and
depth of the water.
· Students observe and record the movement of the water and the appearance
of the bottom of the pond.
