Molecules form when individual atoms create bonds by sharing electrons. Understanding how atoms combine to make molecules allows scientists to predict many of the physical and chemical properties of substances. Since the outermost eight electrons are key to forming compounds, this unit shows how the Octet Rule provides a basis for predicting how atoms may gain, lose, or share electrons to fill the slots in their outer shells. A fundamental understanding of how electrons form bonds leads to the three-dimensional shapes of molecules and has implications in all aspects of chemistry. Part of the series Chemistry: Challenges And Solutions.

What are explorers? What do they do? What skills do they need? Is exploring done today? How can students be explorers? Following a summary of the 18-month Lewis and Clark expedition, elementary students learn about Will Steger, contemporary arctic explorer. Emphasizes the importance of keeping a journal to record what is seen and heard. Students explore nearby woods and share their discoveries.
Since the time of the ancient Greeks, humans have been using spider silk to dress wounds. Scientists now know spider webs not only have healing qualities, they can be stronger than steel. University of Wyoming Molecular Biologist Randy Lewis adds an almost science fiction aspect to the study of spider silk: making large quantities of it by “growing it” in goat’s milk. With funding from the National Science Foundation, Lewis has cloned and sequenced genes for the proteins that make up five different spider silks, some stronger than Kevlar, others more elastic than nylon.
Sharks have been swimming the ocean for 400 million years. But today, many species of sharks are in deep decline due to overfishing and shark finning. A healthy ocean needs sharks. Thankfully awareness of their importance is growing. Part of the "Endangered Ocean" series.
Academy Award winner Jeff Bridges, scientists, and profound thinkers discuss how biology, physics, economics, and politics have contributed to ongoing crises such as climate change and resource depletion. This film features interviews with Wesley Clark, Daniel Goleman, Bob Inglis, Oren Lyons, Leonard Mlodinow, Timothy Morton, Mark Plotkin, Ian Robertson, Piers Sellers, and others.
Nazinga Game Reserve is the success story of one man's determination to restore indigenous wildlife to a dying savannah. Clark Lungren's innovative message to the local tribes in Burkina Faso resulted in increased wildlife and native hunting. Features baboon, hartebeest, antelope, elephant, waterbuck, and warthog. The government and resident natives help protect the sanctuary from poachers.

Covers the concept of ratios and proportions, the correct way to express and write ratios and proportions, ratios and proportions in their simplest form, and comparing ratios and proportions. Provides real-life situations in which ratios and proportions would be applied, such as mixing paint, reading and interpreting map scales, and calculating map distances.
What are the characteristics of frogs and toads? What kinds of habitats do they live in? What are some of the common myths and beliefs about them? Answers these questions and explains how frogs and toads differ. Describes ways humans have revered and slandered frogs throughout history. Provides facts that explain their role in folklore. Discusses the decline in the current frog population and its serious consequences. Includes discussion topics and activities.
Explores the world of butterflies and bees. Segment 1, The Lives of Butterflies and Moths. Describes the four stages of the life cycle of the butterfly and moth: egg, larva (caterpillar), pupa, and adult butterfly or moth. Shows how their diet and defense systems are necessary for survival. Segment 2, Bees and Plants. Explains pollination and why plants depend on bees for survival. Suggested classroom activities follow each segment.
Presents three key concepts about chemical reactions and energy changes: exothermic and endothermic reactions, reaction rates involving temperature and concentration, and catalysts. Each concept is illustrated with a variety of experiments and computer animation to illuminate what is happening both visibly and at the molecular level.
Students learn and explore the major features of the skin, skeletal, and muscular systems. Special attention is given to the care and maintenance of skin, skeletal, and muscular systems. Concepts and terminology include: integumentary system, layers of skin, sweat glands, bone, osteocytes, periosteum, marrow, cartilage, ossification, types of joints, ligaments, types of muscle tissue, and voluntary and involuntary muscle.
Presents three key physics concepts about force and motion: constant speed, acceleration, and gravity and falling. Each concept is illustrated with a variety of experiments and computer animation to illuminate what is happening both visibly and at the molecular level.
Turn light source on to explore. Observe what happens in the observation window as you set up different combinations of light source and molecule. Note this simulation is the first to support our zoom and magnification feature, so zoom in for a closer look, if you need to.

Genetic modification of organisms and cloning is controversial. Looks at the way humanity has modified genomes of plants and animals used for food since the dawn of agriculture. As knowledge of cells and genetics has increased, so has humanity's ability to alter genomes. Shows animations of how genetic engineers are now able to construct and insert genes for desirable characteristics into plants and how technology is used to increase numbers of animals with desirable traits and screen out those with disease or lower food yields.
Uses microphotography and graphics to examine different kinds of plant and animal cells, discussing their structures and tissues. Defines mitosis and meiosis as forms of cell division and illustrates each. Video has three 5-minute segments for convenience.
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.
Understanding the interatomic forces that give structure and properties to different types of solids is essential for the creation of new alloys, the development of useful polymers, and the creation of many other kinds of materials. Chemistry is not only an excellent entry point to predicting how a new material behaves but is also a continuous process of innovation and discovery.

Storyteller Heather Forest uses song, pantomime, games, and discussion to introduce young students to the human body. Talks about key body parts and how they move; how the heart, lungs, and brain keep the body running; how the bones, joints, and muscles hold the body up and help it move; and how our senses help us enjoy the world. Introduces principles of healthy eating, daily exercise, and adequate rest.
