What happens to the body during sleep? Explores the mystery of REM sleep, shows a computer display of the waves that sweep across the brain during sleep, and presents extraordinary footage of a cat "acting out" its dreams. The analogy of comparing sleep to a ship on automatic pilot graphically illustrates how some functions must and do continue while the conscious brain is asleep.

A cycle or rhythm is a repetition of behaving in a regular pattern. There are many natural cycles for living and nonliving things on earth. Covers circadian rhythm (behavior based on a 24-hour cycle), annual rhythm (based on a yearly cycle), the water cycle, and the oxygen and carbon cycle. Highlights familiar examples of each. Quiz after summary.

Explores the strange and relatively unknown world of sleep-a world in which we spend approximately one-third of our lives. Shows how the discovery of REM (Rapid Eye Movement) during our dream period in the early 1950s by Dr. Nathaniel Kleitman at the University of Chicago brought about an understanding of the mechanism of sleep. Before his discovery, it was believed that during sleep the brain was in a state of rest. Also, overviews the nature and frequency of dreams and nightmares, and sleep disorders such as insomnia, apnea, and narcolepsy that affect millions of Americans.
Living things go through changes in the course of their lives, referred to as life cycles. This program explains the life cycles of living organisms, specifically focusing on plants and animals. Video footage and colorful animations illustrate how living things change. Important terminology includes egg, seed, growth, metamorphosis, germination, stage, larva, pupa, nymph, and adult.
Learn the differences between sedimentary, metamorphic, and igneous rocks.
The cell cycle, or cell-division cycle, is the series of events that take place in a cell that cause it to divide into two daughter cells. In this episode, Pinky and Petunia discuss the steps of the cell cycle and what happens when the cell cycle doesn't work correctly. Part of "The Amoeba Sisters" series.
Rocks, a naturally formed material that covers the earth, are classified by their origin. Discusses rocks' composition, three types (igneous, sedimentary, and metamorphic), how they are formed, and how they are changed. The rock cycle is a slow, ongoing process.
Features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. Begins with a simple definition, and this helps clarify pronunciation and provides opportunities to transfer words from working to long-term memory. Also concludes with a critical thinking question. For this particular clip, students will focus on water cycle.
Students explore the life cycle of plants. This video discusses the process of plant development from a small seed to a mature plant.
Students examine the rock cycle. The major characteristics of igneous, sedimentary, and metamorphic rocks are highlighted through vivid footage and colorful animations. Important terminology includes rocks, granite, limestone, marble, shale, slate, molten rock, lava, magma, and sediments.
Physical activity and quality sleep are both vital for healthy bodies, as well as healthy brains. Viewers learn the relationship between activity, boredom, and sleep and how each plays a role in healthy development of children. Part of "The Brain" series.
Most bacteria grown by fission, one cell dividing into two. When nutrients are abundant, this can result in exponential growth, with a large increase in the number of cells over a surprisingly short period of time. Bacterial cell division and the characteristics of exponential growth are illustrated with four, 3D printable models

Part of a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. Begins with a simple definition of the term and concludes with a critical thinking question. For this particular video, students will focus on the lunar cycle. Part of the Science Video Vocab Series.
With support from the National Science Foundation, neurologist Ken Paller and his team at Northwestern University are studying the connection between memory and sleep, and the possibilities of boosting memory storage while sleeping. A lot of the evidence has shown that slow-wave sleep is particularly important for some types of memory, and Paller’s goal is to better understand the fundamental brain mechanisms responsible for memory. And that, in turn, may help people with memory problems, including those who find themselves more forgetful as they age. Part of the National Science Foundation Series “Science Nation.”
The cell cycle is the series of events that cells go through as they grow and divide. This title provides a discussion on each of the stages of the cell cycle: prophase, metaphase, anaphase, telophase, and cytokinesis. Part of the "Biology" series.
Crisp, vivid video footage illustrates how living things change throughout their lives. Focuses on the life cycles of plants, insects, and frogs.
