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.

Introduces the concept that everything is made of matter, and examines the three states of matter. Defines and examines a range of solids, liquids, and gases. Uses graphics to show the effects of heat on atoms and molecules in solids. Summarizes each segment.
Anything that takes up space or has mass is matter. Under certain conditions matter can be a solid, liquid, gas or plasma. Different states of matter can be combined in suspensions, and solutions and mixtures can be taken apart. Exploring the physical and chemical properties of matter provides insight into nature and a glimpse at how scientists and engineers use this knowledge to shape our world.
Water commonly exists in three different forms: ice, liquid, and vapor. The different phases of water serve as the foundation to teach students about solids, liquids, and gases. Other common everyday examples of solids, liquids, and gases are also featured. Concepts and terminology discussed include: particles, volume, shape, and temperature.
A teenage narrator presents general information about matter: its characteristics, qualities, properties, and states and changing states. Gives definitions and a review.
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. Part of the series: Chemistry: Challenges And Solutions.
Longitudinal waves carry energy through air, water, and solids. They compress and expand the medium in the same direction as the energy is transferred.
This segment answers the questions surrounding the origins of Earth. Scientists use clues from the past to help explain how Earth formed. Other topics covered include matter, minerals, and rocks. Part of the "Earth Science" series.
Introduces water and its properties and uses. Shows water's three forms: liquid, gas, and solid and how it changes form through evaporation, condensation, and freezing. Emphasizes that all living things need water to survive. Demonstrates the water cycle and discusses ways people use this essential liquid.

Silicon is a chemical element with the symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic lustre.
Students explore the concept of volume and ways to measure it. Concepts and terminology include liquid, solid, liter, milliliter, cubic centimeter, beaker, and graduated cylinder.
Erbium is a chemical element with the symbol Er and atomic number 68. A silvery-white solid metal when artificially isolated, natural erbium is always found in chemical combination with other elements.
Iodine is a chemical element with the symbol I and atomic number 53. The heaviest of the stable halogens, it exists as a lustrous, purple-black non-metallic solid at standard conditions
Lithium is a chemical element with the symbol Li and atomic number 3. It is a soft, silvery-white alkali metal.Under standard conditions, it is the lightest metal and the lightest solid element.
How can substances, such as water, exist in several dramatically different phases? Easy-to-understand examples illustrate how phase changes occur. Additional concepts and terminology include states of matter, particles, solid, liquid, gas, plasma, melting, freezing, vaporization, boiling, evaporation, condensation, and sublimation.
What's the difference between thermoplastics and thermoset plastics? The primary physical difference is that thermoplastics can be remelted back into a liquid, whereas thermoset plastics always remain in a permanent solid state. Part of the "Ask a Scientist" series.
Colony formation on semi-solid medium is basic characteristic of many different bacteria and an important property for microbiologists. These models illustrate the different types of colonies formed, what a colony reflects at the cellular level, how microbiologists obtain isolated colonies, and what happens when cells swarm instead of forming colonies.

Hawaii is a state in motion, formed by magma-spewing volcanoes that turn into basalt. The native population of Hawaii considers hot lava an instrument of creation even if it destroys everything in its path. Viewers trace the ever-changing landscape of the Hawaiian Islands due to the active tectonic forces of the region.
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 what it means for substances to freeze. Part of the Science Video Vocab Series.
