Through the wonders of close-up photography, this unique CD-ROM brings
students face-to-face with the inner workings of a freshwater pond, the myriad creatures
and plants that reside there, and the dynamic interactions that go on beneath the surface.
This disk features a library of reference information, images, illustrations, clip art, video
clips and more!

Section One provides a general overview of ecosystems in general and the pond
ecosystem in particular, and introduces the various life forms that reside there. These
include emergent and submerged rooted water plants, microscopic and small
macroscopic animals, aquatic insects, molluscs, amphibians, reptiles, birds and
mammals. Spring and fall overturns are explained and numerous links lead students to
images and text that round out their understanding.

Section Two delves into microscopic pond life in great detail, covering: the
different types of cells, eubacteria, cyanobacteria, euglenoids, diatoms, desmids,
dinoflagellates, flagellates, amoebas, ciliates, suctorians and green protists. Eye
stopping photographs of many examples accompany detailed information.

Section Three presents pond plants and information about how they grow and
reproduce, an what lives on and among them: larch, weeping willow, paper birch, poplar,
alder, jewelweed, ferns, mosses, phragmites, aromatic water lily, variable pond weed,
floating heart, submergent rooted plants, cardinal flower, sundew.

With more striking close-up photographs, Section Four presents the small
invertebrate life that is so plentiful amid the shallow water vegetation and pond sediments:
rotifers, gastrotrichs, hydras, flatworms, nematodes, bryozoans, microannelids,
cladocerans (water fleas), and microcrustaceans. Again, numerous links connect these
creatures to other members of the pond community.

Section Five introduces food chains and trophic levels, photosynthesizers,
herbivores, carnivores, omnivores and decomposers. In the process, the numerous pond
vertebrates—fish, amphibians, reptiles, birds and mammals—are reintroduced and
presented in depth, along with the microlife forms previously covered. Life styles, feeding
behavior, mating and reproduction, as well as their dependence on other pond life are
presented for the vertebrates.

Section Six provides Field Trip and Laboratory tips. Various classroom and field
projects, ways to collect and preserve specimens, how to calculate a diversity index,
safety considerations, etc.

Section Seven is a unique curriculum section that provides the means to link the
vast library of resources to key, curriculum-based science topics.
