Does the wax of a candle melt or burn? In this scientists conduct an experiment to determine what really happens when a candle is lit. They also develop a method to calculate the amount of hair on a head. Part of the House of Science Series.

Explores how studying the atom forced us to rethink the nature of reality itself, encounters ideas that seem like they're from science fiction but in fact are a central part of modern science, and discovers there might be parallel universes in which different versions of us exist and finds out that empty space isn't empty at all, but seething with activity. The world we think we know, the solid, reassuring world of our senses, turns out to be a tiny sliver of an infinitely weirder and more wonderful universe than we had ever conceived of in our wildest fantasies.
What is an atom? It is the smallest particle of an element, and everything is made up of atoms. They consist of three basic particles: protons, electrons, and neutrons. The scientific community has experienced significant breakthroughs which have contributed to the understanding of atoms. Other topics covered include atomic number, atomic mass, Bohr model, electron cloud, and isotope.
Part of a series that features a wide variety of video footage, photographs, diagrams, graphics, and labels. For this particular video, students will focus on the measurements of the International System of Units (SI). Part of the Science Video Vocab series.
There is a massive southern ocean current almost two miles below the ocean's surface. Recent measurements found it’s the strongest current ever recorded at this depth and transports 40 times as much water as the Amazon River. The current carries dense, oxygen-rich water and has a direct influence on temperatures around the world. Part of the "News of the Day" series.
In this episode, Dr. Varoujan Gorjian explains the mind-boggling expansion of the universe. He uses a balloon to demonstrate how space is expanding. Part of the "Ask an Astronomer" series.
Features different systems of measurement and their value to science in five separate segments. Stardust Elements: Looks at the life cycles of stars and explains how the death of a star seeds the universe with all the elements of the periodic table. End of Dinosaurs: Debates several scientific theories about why and how dinosaurs became extinct. Earthly Thermometers: Demonstrates how the Fahrenheit, Celsius, and Kelvin scales measure the same thing in different ways and why we need precise measurements of temperature. Frozen in Time: Pieces together the past of a 5,300-year-old man whose body was preserved in ice in the Italian Alps. Hurricanes Take the Heat: Follows researchers who study how hurricanes form and try to predict where the next one will strike.
Students explore the smallest, but most important units of life: cells. They also gain an understanding of common cell parts through lifelike animations. Additional concepts and terminology include building blocks of life, animal cell, cell membrane, nucleus, cytoplasm, plant cell, photosynthesis, cell wall, chloroplasts, organelles, and role of cells in the body.
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.
When she was young, Danielle Sumy rode a roller coaster that simulated an earthquake. Her experience on the roller coaster launched her quest to understand how earthquakes happen. She describes how this encounter and her early love of science motivated her to become a geophysicist. Part of the “EarthScope Chronicles” series.
The study of thermodynamics can lead to predicting how chemical reactions will proceed or how much energy is required or released during the reactions. To better understand chemical reactions, a new thermodynamic value called “enthalpy” is introduced. Students will examine the practical applications of bond enthalpies, calorimetry, and other measurements of the energy in chemical reactions. They will also see how the understanding of thermodynamics and enthalpy is helping scientists optimize the use of crop waste for biofuels and build more efficient automobile engines. Part of Chemistry: Challenges and Solutions Series.
Part of the "A 3-D Demonstration" series. Looks at physics principles behind AC and DC generators. Examines the relationship between a changing magnetic field and the induction of electric current. A hand rule is introduced to predict the generator effect in a linear length of conductor exposed to a changing magnetic field. The behavior of a rotating coil in a magnetic field leads to the practical construction of an AC motor. Introduces split-ring commutator generators, as well as the more common alternator as a means of generating DC electricity. Specific modules include Generating Electricity, Inductors, Generator Left-Hand Rule, Generator Electromotive Rule, AC Generators, and DC Generators. Correlates to all National CTE Organizational Standards (including the provisions of the Perkins Act).
With support from the National Science Foundation, Center Director Doug Keszler and his team in the College of Science at Oregon State University are developing the next generation of electronic circuits, starting with the basic computer chip. In the manufacturing process, they want to replace bulky carbon compounds with metal oxides, in order to put more transistors onto a chip. The new process would be cleaner, faster and cheaper. Part of the National Science Foundation Series “Science Nation.”
Photogrammetry is the science of making precise measurements by the use of photography. United States Geological Survey (USGS) geologist Angie Diefenbach describes how she uses a digital camera and computer software to understand the growth rate of lava domes during a volcanic eruption.
Firefighters risk their lives every time they run into a burning building. But, new technology may soon be watching their backs, no matter how far they venture into the flames and smoke. With support from the National Science Foundation, TRX systems is developing a new sensor system that can track firefighters where GPS units often fail.
What does a mirror tell us about light? Illustrates 11 computer-animated video units for one aspect of light's behavior-reflection. Euclid's geometric optics and his findings on the perception of distance and perspective lead to a discussion of the Law of Reflection, linking angle of incidence with angle of reflection, and the concepts of absorption, transmission, and diffuse reflection. Explains the principles involved with plane, concave, and convex mirrors, including vertex, principle axis, center of curvature, radius of curvature, and virtual image. Shows a group of "mirror equations" how an object's location can be determined by using the laws of reflection.
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.
While the human brain and nervous system are wired with hundreds of billions of nerve cells, or neurons, sea slugs can get by with tens of thousands. Ironically, sea slugs reveal a lot about the chemistry of the human brain and nervous system. In fact, they are ideal as study subjects for research on learning, memory, and how neurons control behavior. With support from the National Science Foundation, analytical chemist Jonathan Sweedler and his team at the University of Illinois are working to develop new measurement tools that enable insights into the function of individual cells in the central nervous systems of slugs and other animals in order to uncover novel neurochemical pathways. Part of the National Science Foundation Series “Science Nation.”
What is physics? The Standard Deviants introduce students to some of the basic vocabulary and concepts found in physics. Topics covered include scientific notation, numbers, units, scalars, and vectors. Part of the "Standard Deviants School: Physics" series.
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 wave. Part of the Science Video Vocab Series.
