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 term mass. Part of the Science Video Vocab Series.

Part of the "Gunther's ER" series. As Dr. Gunther von Hagens makes clear, a shortage of blood can mean that insufficient oxygen is reaching the major organs, usually resulting in shock and organ failure. Opens with a graphic bleeding demonstration, re-creating injury to blood vessels in the hand of a cadaver. Also examines the consequences of blood loss in the body's vital organs by creating knife wounds in the torso of a frozen body, then sawing it into slices to reveal the path of the blades and the shocking extent of the damage. Also explores a lesser well-known cause of blood loss-fractured bones-which von Hagens illustrates in an experiment in which a femur dissected from a fresh cadaver is made to bleed as it would in life. NOTE: Viewer discretion is advised. Contains clinically explicit language and nudity.
Using a balanced chemical equation to calculate amounts of reactants and products is called stoichiometry. It is a super technical-sounding word that simply means using ratios from the balanced equation. Topics covered in this program include the metric system, balancing equations, molar conversions, mass percent, empirical formulas, and limiting reactants. Part of the "Chemistry" series.
The Standard Deviants discuss the three laws of Sir Isaac Newton. This branch of study is also known as Newtonian physics, and it applies to everyday conditions of speed, time, and gravitational pull. Other topics covered include forces in equilibrium, mass as opposed to weight, inertia, static and kinetic friction, and tension. Part of the "Standard Deviants School: Physics" series.
Visualize the gravitational force that two mass spheres exert on each other. Move spheres in meters, change mass in kilograms, and observe changes to the gravitational forces that m1 and m2 exert on each other.

Weather is the state of the atmosphere, and it refers to the day-to-day temperature and precipitation activity. The difference between air pressure, temperature, and moisture influence weather-related phenomena. Other topics covered include evaporation, relative humidity, clouds, precipitation, rain gauge, air mass, front, thunderstorm, hurricane, tornado, weather forecast, meteorologist, and satellite imagery.
Part of the "Chemistry in Action" series. Numerous real-life examples of elements are exemplified in the table. Animations and graphics illustrate concepts not easily achieved through other instructional strategies. Specific patterns in the periodic table are highlighted. Introduces the following terminology: atomic structure, atomic number, atomic mass, periods, and families.
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.
This creature was found 1,800 feet deep in the ocean. It’s called a basket star. This extraordinary invertebrate has a mass of twisting and turning arms that can measure a meter long. Each branch has tiny sharp hooks allowing the creature to capture prey, and it feasts mainly on zooplankton. Basket stars are able to grow their limbs back if they are broken or chopped off by predators. Part of the "Creatures of the Deep" series.
Earth’s climate is changing in a big way, and it’s because there's more carbon dioxide in the atmosphere than at any point in human history. But Earth’s climate has changed before. How are scientists studying the impact of human behavior on climate? They are collecting ice cores and analyzing the tiny bubbles of ancient atmosphere trapped in the cores. Part of the "It's Okay to Be Smart" series.
How did 20th-century physics change long-held notions of light's makeup and behavior? This group of 12 concise computer-animated videos illustrates Einstein's monumental contributions to the study of light. Shows how rudimentary ideas of material wave motion yielded to more advanced concepts of electromagnetic waves by detailing Einstein's conclusions about the speed of light and his conception of time, which-given his findings on mass and energy-proceeds according to variable frames of reference. Conveys relativistic thought experiments through helpful animation, which demonstrate simultaneity, time dilation, length contraction, and relativistic mass.
In nuclear physics, nuclear fusion is a nuclear reaction in which two or more atomic nuclei come close enough to form one or more different atomic nuclei and subatomic particles (neutrons and/or protons). The difference in mass between the products and reactants is manifested as the release of large amounts of energy. This difference in mass arises due to the difference in atomic "binding energy" between the atomic nuclei before and after the reaction. Fusion is the process that powers active or "main sequence" stars, or other high magnitude stars.

Dr. Carolyn Brinkworth addresses a famous science fiction scenario in this episode. She discusses the three requirements for planets to form around binary stars. Part of the "Ask an Astronomer" series.
Students learn the process of weighing common objects. Concepts and terminology include matter, mass, weight, scale, and metric system.
Students will learn about force and the effects of force on objects. Visual examples and real-life demonstrations promote an understanding of how things move. Important terminology includes force, work, friction, gravity, mass, and acceleration.
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.
Aluminium is a chemical element with the symbol Al and atomic number 13. It is a silvery-white, soft, non-magnetic and ductile metal. By mass, aluminium is the most abundant metal in the Earth's crust.

Over the many billions of years of the Earth's history, the planet has never stopped changing shape. Massive tectonic forces have sculpted and resculpted the world in a never-ending process. This episode chronicles the Himalayas, investigates how Siberia joined other land masses, and discusses tectonic activity that impacts Japan and Indonesia. Part of the "Voyage of the Continents" series.
Students explore the relationship between observations and measuring things in science. Specific ways of measuring length, mass, volume, and temperature are demonstrated using tools common to the classroom. Other terminology includes unit of measurement, meter stick, metric ruler, balance, graduated cylinder, and thermometer.
