Looks at how the male and female bodies are prepared for their task of continuing the human race. Shows the characteristics of sperm and ova and how each contains a partial blueprint for the future offspring. The mechanism of cell division is shown through exceptional microphotography, and the mechanisms of heredity are carefully described. NOTE: Shows some nudity.

This transmission electron micrograph of a mitochondrion shows an oval, outer membrane and an inner membrane with many folds called cristae. Inside of the inner membrane is a space called the mitochondrial matrix. Unlike prokaryotes, eukaryotic cells have a nucleus and other membrane-bound organelles that allow the cell to compartmentalize different functions. These videos will provide an overview of eukaryotic cells and will take you through the structures and functions of the various organelles found within the plasma membrane.

Labelled parts of the Human Inner Ear
One of the fifteen parts of the "Farm to Market" series. Fruits such as bananas, papayas, pineapples, and coconuts grow in warm tropical areas. Shows how these fruits and others are grown, harvested, and transported to market.
Discusses the various feeding strategies and adaptations of the different species of microorganisms. Some form symbiotic relationships with one another while others are predatory. One of nine segments in a series, with all nine available on a DVD.
Part of a series that features a wide variety of video footage, photographs, diagrams, graphics, and labels. Also concludes with a critical thinking question. For this particular video, students will focus on the diverse group of eukaryotic organisms known as protists. Part of the Science Video Vocab series.
Many microorganisms thrive in the polluted water that is abundant with their food: bacteria and other protists. One of nine segments in a series, with all nine available on a DVD.
Explores the microscopic organisms known as the ciliates. They are named for the tiny hairs that cover their bodies. Discusses different species, their habitats, and how they survive. One of nine segments in a series, with all nine available on a DVD.
Part of the "The Biology Classics" series. The cross-eyed flatworm, planaria, is both scavenger and predator, depending upon opportunity. Details food-seeking behavior, the flatworm's feeding method, locomotion (produced by a carpet of cilia), internal anatomy, and reproduction through the remarkable process of regeneration.
Part of the "Branches on the Tree of Life" series. The bacteria section uses compelling microscopy of living bacteria to examine their structure, physiology, behavior, and the vital roles these microbes play in the biosphere.
Rotifers are found in still waters, and there are over 2,000 species. They all have two crowns of cilia that work in sync to help them move and gather food. One of nine segments in a series, with all nine available on a DVD.
Part of the "The Biology Classics" series. Paramecia are a group of unicellular ciliate protozoa. Shows how paramecia move, feed, digest, assimilate nutrients, achieve water balance, deploy defensive weapons, reproduce, and engage in the sexual exchange of genetic material. Utilizes state-of-the-art microscopy techniques to present a compelling new picture of the life of paramecia.
Scientists investigate the microbes found in Yellowstone National Park hot springs, geysers, and other pools of water. Micro life is thriving in the extreme environments of the hot springs, and microbiologists believe the diversity of life found at Yellowstone will aid in studying life beyond our planet. Segment of video from Wild Chronicles Series.
Genes, those traits passed down to us by our parents, are the things that make each of us different from the others. This question-answer format covers basic information about genes, chromosomes, cell division, dominant and recessive genes, and fertilization. Illustrates Mendel's rules of heredity. Covers advances in the fields of DNA, genetic engineering, and gene therapy. Reviews major points.
Part of the "Inside the Living Cell" series. Describes the properties of the plasma membrane, how it governs the kinds of molecules that go in and out of cells, and how cells feed by engulfing (phagocytosis) and drinking in (pinocytosis) fluids. Also reviews membrane structure, osmosis, transport proteins, active transport, cell eating, cell drinking, and receptor proteins.
There is a massive southern ocean current almost two miles below the ocean's surface. Recent measurements found it’s the strongest current ever recorded at this depth and transports 40 times as much water as the Amazon River. The current carries dense, oxygen-rich water and has a direct influence on temperatures around the world. Part of the "News of the Day" series.
Climb aboard the Cyclops, a microscopic research vessel, and investigate an amazing hidden world on which all living things depend. The Cyclops houses a team of scientists known as the Micronauts and guides them through their discoveries of biological classification, diversity, and ecology. In this episode, the Cyclops is washed out of the pond and tumbles into a rapidly flowing stream. In the rapids, they discover aquatic insects living under rocks. Through their careful observations, the Micronauts learn the insects are adapted for living on water-swept rocks. Part 7 of the Microscopic Monsters Series.
Students explore the various properties of magnets and the characteristics of magnetic force. Graphics and real-life footage explain how magnets are used in generating electricity. Electromagnets and their many uses are demonstrated as well. Other terminology includes: magnetic poles, magnetic field, electric motor, generator, solenoid, and electromagnetism.
Climb aboard the Cyclops, a microscopic research vessel, and investigate an amazing hidden world on which all living things depend. The Cyclops houses a team of scientists known as the Micronauts and guides them through their discoveries of biological classification, diversity, and ecology. In this episode, the crew continues to observe a variety of bacteria. They discover that bacteria is the food of choice for large single celled protists in the pond. Their observations lead them to make conclusions about the food chain found in the pond. Part 6 of the Microscopic Monsters Series.
Diagram of the internal view of the female reproductive system. Design modalities for the image include braille with and without labels, print with and without labels in greyscale, color, and texture.
