Lab experiments test for oxygen and show its reaction to iron and carbon.
Oxygen is the chemical element with the symbol O and atomic number 8. It is a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds.After hydrogen and helium, oxygen is the third-most abundant element in the universe by mass.

New research finds that hummingbird species living at high altitudes have evolved hemoglobin with enhanced oxygen-binding properties so they can thrive in oxygen-poor environments. A team of scientists demonstrate how hummingbirds adapt to life at high altitudes.
Figure 2.9 (OpenStax, Biology 2e) caption: Two or more atoms may bond with each other to form a molecule. When two hydrogens and an oxygen share electrons via covalent bonds it forms a water molecule.
Illustration showing the carbon cycle using animals and plants.
Ocean “dead zones” along the Washington and Oregon coasts are threatening critical U.S. fishing areas. These oxygen-depleted regions, that loose virtually all of their marine life in the summer, are expanding, and new ones are appearing in the Pacific Ocean. With support from the National Science Foundation, Oceanographer Jack Bath is also using an impressive new tool, an unmanned underwater glider that provides round the clock monitoring of these zones.
Figure 2.27 (OpenStax, Biology 2e) caption: These functional groups are in many different biological molecules. R, also known as R-group, is an abbreviation for any group in which a carbon or hydrogen atom is attached to the rest of the molecule.
Part of the "Gunther's ER" series. The human brain suffers irreversible damage if deprived of oxygen for even a few minutes-a fact Dr. Gunther von Hagens demonstrates by utilizing human cadavers as examples. Simulating an artery injury to illustrate oxygen depletion through blood loss, von Hagens then focuses on problems affecting the trachea, the top priority for ER doctors. In order to show the major structures of the airway and how they can be blocked by foreign objects, von Hagens inserts an endoscope into his own throat and saws a frozen body's throat in half, revealing the major structures of the airway and their potential weaknesses. Red Cross first-aid expert Emma Rand explains simple techniques for clearing the airway, while emergency medicine consultant Dr. John Heyworth shows how paramedics treat complex trachea damage. NOTE: Viewer discretion is advised. Contains clinically explicit language and nudity.
Students explore the diversity of plants and the important characteristics they have in common. The importance of plants in everyday life is stressed. Terminology includes oxygen, fruits, vegetables, seeds, and spores.
Protactinium (formerly protoactinium) is a chemical element with the symbol Pa and atomic number 91. It is a dense, silvery-gray actinide metal which readily reacts with oxygen, water vapor and inorganic acids.I
Ollie and Hanna receive a lesson on breathing. Suzi, with the help of a friend, explains why all living things must breath. Part of "My Little Planet" series.
Students learn how to differentiate mixtures, solutions, elements, and compounds. Additional concepts and terminology discussed include: element, pure substance, properties, atoms, molecule, compounds, types of mixtures, suspension, colloid, and alloy.
Explains the scientific concepts of photosynthesis, respiration, and enzymes. Laboratory experiments demonstrate: the rate of photosynthesis in greenhouse plants; the amount of oxygen used by the body during respiration at varying speeds; and the reaction times of different enzymes.
What happens when an organism can't perform aerobic cellular respiration because oxygen isn't available? Explore fermentation with Pinky and Petunia. This episode focuses on alcoholic fermentation and lactic acid fermentation. Part of "The Amoeba Sisters" series.
Figure 2.15 (OpenStax, Biology 2e) caption: When we mix table salt (NaCl) in water, it forms spheres of hydration around the ions.
Learn about some of the bold and brilliant ideas researchers and conservationists have to rescue corals and coral reefs from disaster. Part of the "Coral Comeback" series.
Often hard-to-understand concepts of air, gases, air pressure, and layers of the atmosphere are plainly explained in this video. Concepts and terminology: oxygen, nitrogen, layers, weather, jet stream, and northern lights.
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 air. Part of the Science Video Vocab Series.
