A Closer Look at Pondlife

Producer: Educational Images, Ltd.

Using close-up photography, this 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. The disk features a library of reference information, images, illustrations, clip art, videoclips and more. Section 1 provides an overview of ecosystems in general and the pond ecosystem in particular, and introduces the life forms that reside there. Section 2 delves into microscopic pond life; it covers the different types of cells, eubacteria, cyanobacteria, euglenoids, diatoms, desmids, dinoflagellates, flagellates, amoebas, ciliates, suctorians and green protists. Section 3 presents pond plants and information about how they grow and reproduce, and what lives on and among them. Section 4 presents the small invertebrate life that is so plentiful amid the shallow water vegetation and pond sediments; it covers rotifers, gastrotrichs, hydras, flatworms, nematodes, bryozoans, microannelids, cladocerans (water fleas), and microcrustaceans. Section 5 introduces food chains and trophic levels, photosynthesisers, herbivores, carnivores, omnivores and decomposers. Section 6 provides field trip and laboratory tips. Section 7 is a unique curriculum that provides the means to link the vast library of resources to key, curriculum-based science topics.
