During a trip to CERN in Geneva, Switzerland, host Dianna Cowern discusses dark matter with a theoretical physicist. Scientists at CERN are using the Large Hadron Collider to search for dark matter. Part of the "Physics Girl" series.

How does paper change when it is torn up? Or what happens to ice as it melts. These are examples of physical changes in matter, and students explore some of the different ways matter changes physically. Concepts and terminology discussed include: freezing, melting, condensation, boiling, and evaporation.
The formation of molecular bonds is an essential part of keeping matter together. The sharing of charges between atoms helps them become more stable. Other topics covered include sharing electrons, bonding tendencies, isomers, VSEPR theory, and molecular geometry. Part of the "Chemistry" series.
Nano expert Lisa Friedersdorf from the National Nanotechnology Coordination Office provides information on nanomaterials that have existed throughout history. She also gives additional information on the nanoscale. Part of the “Ask a Scientist” series.
What are the differences between solids, liquids, and gases? In this program, students will investigate real-life examples of the various phases of matter. Colorful animations illustrate how these states differ based on the movement of particles. Other topics covered include plasma, crystalline and amorphous solids, viscosity, freezing, vaporization, evaporation, and condensation.
Thermodynamics deals broadly with the conservation and conversion of various forms of energy. It also describes the relationships between energy and the changes in properties of matter. Other topics covered include Hess's law, the laws of thermodynamics, and the Gibbs free energy. Part of the "Chemistry" series.
Dark matter is a scientific mystery. But physicists like Dan McKinsey theorize it must exist because without it, the universe would look quite different. With support from the National Science Foundation, McKinsey and a team of scientists from across the U.S. and Europe are hard at work on the Large Underground Xenon, or LUX, experiment. Nearly a mile straight down an old mine shaft at the Sanford Underground Research Facility in Lead, South Dakota, the team searches for the existence of one possible type of dark matter called weakly interacting massive particles, or WIMPs. Part of the National Science Foundation Series “Science Nation.”
Solutions are uniform mixtures of molecules in which any of the phases of matter can be dissolved in another phase. Whether solids, liquids, or gases, solution chemistry is important because most chemical reactions, whether in the laboratory or in nature, take place in solutions. In particular, solutions with water as the solvent are the core of all biology. Extending the particle model of matter to solutions enables chemists to predict what will happen to a deep-sea diver who breathes different mixtures of gases or to the life forms in the ocean as carbon dioxide levels rise in the atmosphere. Part of Chemistry: Challenges and Solutions Series.
Students learn the process of weighing common objects. Concepts and terminology include matter, mass, weight, scale, and metric system.

Waves are all around. They are a disturbance that travels through space and matter transferring energy from one place to another. Find out about the nature, shapes, and impacts of waves in this animation.
Bill Nye demonstrates simple experiments that can be done at home. These show scientific ideas about air pressure, weighing gas, bending light, static electricity, and others. Emphasizes that a good experiment is repeatable.
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 different states of matter. Part of the Science Video Vocab Series.
Will we be able to grow all of our fuel in the future? Uncovers a biofuel jet truck, a record-breaking flying machine, and a unique car made almost entirely of organic matter. Also, explores new ways of harvesting energy from biomass.
Students learn how chemicals from pharmaceuticals and personal care products are entering the waterways upstream from fish, crabs, and drinking water intakes. There is evidence that some members of these species are becoming intersex due to estrogenic compounds being disposed of improperly. Please note: Preview of this title is highly encouraged due to sensitive subject matter.
Joyce Poole, elephant researcher and conservationist, shares her insights and convictions about this large, dignified animal. Closeup photography support her discussion about elephant family units, mating rituals, behaviors, and "vocabulary." Recently lifted bans on elephant ivory means this endangered animal is even more at risk.
A black hole is a region of space having a gravitational field so intense that no matter or radiation can escape. In this episode, host Dianna Cowern leads a discussion on black holes and reviews Stephen Hawking's last paper on black holes. Part of the "Physics Girl" series.
This video explains the vital role elements and compounds play in making up matter. Everyday examples of different types of mixtures help students realize the important role they play in daily life. Other topics covered include elements, compounds, homogeneous and heterogeneous mixtures, colloid, suspension, solution, solvent, and solute.
A scientist from NASA explains how to build an icy model of a comet, complete with shooting jets. This activity provides an opportunity for students to make observations, discuss changing states of matter, and demonstrate measuring skills. Part of the “DIY Space Classroom Activities” series.
Marli Lintner, an avian veterinarian, shares her expertise on choosing a pet bird, common species, bringing a bird home, proper housing, nutrition and diet, health matters, trimming wings and nails, and taming a bird.
