While engrossed in observing the food capturing and feeding methods used by predatory flatworms, the Cyclops crew becomes trapped by the tentacles of Hydra where they receive a visible lesson in the process of digestion.
Subjects: Biology
-
White Water Adventure
Trying to return to duck weed base, the Cyclops is channeled into the pond outlet, where they tumble into a rapidly flowing stream and discover a world of aquatic insects adapted for life in flowing water–even waterfalls.
-
Discovering a Forest Microcosm
Washed onto a sandbar, the Cyclops crew assembles their terra-rover and discovers a world dominated by bacteria, fungi, and tiny invertebrate animals–a forest floor community on which the trees and other plants depend for processing nutrients needed for plant growth.
-
Backyard Biodiversity
The micronauts discover that gardens support an amazing community of small life including herbivorous and predatory insects, pollinating insects and giant earthworms. They tour the worm’s innards while developing theories on the vital roles earthworms play in terrestrial ecosystems.
-
The Biology of Lakes, Ponds, Streams, and Wetlands
This program introduces students to organisms that live in weedy shallows, open water, bottom debris, stream habitats and wetland habitats. The observations include the classical organisms studied in biology. Download free guide from our website.
-
The Biology of Seashores
The Biology of Seashores modular approach makes it ideal for teaching concepts of life science and ecology by focusing on intertidal ecology and the diversity of life found at the seashore. The program can be used as an introduction or review of a general unit on ecology, animal biology, or marine studies, or a unit that concentrates on seashore studies.

Echinoderms
Echinoderms are one branch of the deuterostome line of animal evolution, the branch to which Chordates also belong. Narrated modules cover phylum characteristic and key biological details for five classes: sea stars; brittle stars and basket stars; sea urchins and sand dollars (including developmental stages); sea cucumbers; and crinoids (feather stars).
-
The Genetic Code and Its Translation
Modules: The Protein Nature of Life, Protein Structure, Transcription, Translation and Protein Synthesis, Gene Regulation in Prokaryotes, Classes of Eukaryote DNA, Exons and Introns, Mutations, Renegade DNA – The Viruses.
-
Chordates
The Phylum Chordata includes tunicates, sea lancelets, hagfish, and all familiar vertebrate animals. This program explores how these seemingly diverse animals evolved and how the group is unified by four characteristic structures: a hollow dorsal nerve chord, a supportive notochord, gill silts, and a post-anal tail. Key milestones in vertebrate evolution included improvements in swimming and feeding, the evolution of paired fins and a primitive lung, movement onto the land, and the amniotic egg.

The Domains of Life: Life’s Three Great Branches
The Domains of Life updates the five kingdoms classifications scheme with the latest understanding of life’s organization based on DNA, fossil, and biochemical evidence. The video programs use concise animations and superb microscope footage of primitive cells to describe events that shaped life as we know it today. Includes teacher’s guide.
