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 properties of liquids. Part of the Science Video Vocab Series.

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.
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.
A teenage narrator presents general information about matter: its characteristics, qualities, properties, and states and changing states. Gives definitions and a review.
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.
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.
Caesium has the atomic number 55 and symbols Cs. It is an alkali metal with a silvery-gold color and the only liquid metal from the group of elemental metals, which is liquid near or at room temperature.

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.
The concept of propulsive thrust to move objects over large distances is ancient. Yet, the technology to move an automobile forward or a rocket into space was invented less than two centuries ago. The invention of the solid fuel propulsion system combined with Newton's Third Law is the simplistic basis for modern rocketry. Students will review the history of propulsion and explore its use as a viable energy source of the future.
Acids and bases are important to many chemical processes: maintaining a stable internal environment in the human body, baking a delicious cake, or determining whether a lake can support aquatic life. Reactions involving acids and bases can be described through the transfer of protons. The reactions of acids and bases, which can be monitored with indicators, can range from corrosive behavior to neutralizations that leave no acids or bases behind. To understand the controlling of pH of solutions, buffers are discussed in the laboratory and in the chemistry of the bloodstream. Part of Chemistry: Challenges and Solutions Series.
Lab experiments test for oxygen and show its reaction to iron and carbon.
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.
Lab experiments show how magnesium, zinc, iron, and copper react with hydrochloric and nitric acids. Also shows the displacement of two metals from salts.
Students demonstrate the process for making cheese and how the composition of milk aids the cheese making process.
Matter is everywhere. Students learn how to describe, observe, and measure matter. Additional concepts and terminology include mass, weight, volume, density, hardness, texture, shape, flammability, size, and physical and chemical properties of matter.
Gallium is a chemical element with the symbol Ga and atomic number 31. Elemental gallium is a soft, silvery metal at standard temperature and pressure; however in its liquid state it becomes silvery white.
Bromine is a chemical element with the symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured gas.
