Organic acids, found in common foods, appear as citric acid (lemons), acetic acid (vinegar), and malic acid (apples). Also shows esterification and the formation of an ester.

Lab experiments demonstrate a variety of ways to detect carbon and hydrogen in organic substances. Burns hexane, benzene, cyclohexane, and naphthalene; shows properties of a propane-butane mixture.
A woman with osteoporosis shares her experience, how she copes, and steps she's taken to prevent further bone loss. Physicians explain the disease, the risks and statistics, and the importance of calcium, exercise, and vitamin D earlier in life. Demonstrates a bone density test.
Experiments show the production and properties of carbon dioxide and its use as a fire extinguisher. The second part demonstrates the effect of surface area, temperature, and concentration on chemical reaction rates.
From cyclists to race cars, the motion of an object is determined by the sum of the forces acting on it. An aeronautics engineer works with Newton's three laws of motion to test the best bicycle posture and helmet in a wind tunnel.
This organic chemistry tutorial is divided into two parts. Part 1, "Selected Derivatives, Hydrocarbons," focuses on the properties of glycerol and phenol; Part 2, "Synthetic Substances," demonstrates properties of polyethylene and the depolymerization of polyethylene.
Host Alex Dainis highlights the uses and history of parafilm. It is commonly used in health care, pharmaceutical, and research laboratories for covering or sealing vessels such as flasks, cuvettes, test tubes, beakers, Petri dishes, and more. Scientists and researchers use it in the lab since it is ductile, malleable, nontoxic, and self-sealing.
A soccer stadium is perfect to put to test the principals of physics, math, biology and technology. How to generate certain effect by kicking a ball? With what angle are we able to achieve the longest distance? How is a fixture put together for an Argentine soccer tournament?
One of the harshest environments on earth exists at the place where the sea meets the rocky shore. Students will examine the wide variety of animal and plant life that survive these difficult conditions that are caused by pounding waves during the ebb and flow of the tides.
NASCAR corners are divided into three parts because the car's grip changes in different parts of a turn. The center of gravity in the car challenges crew chiefs to minimize weight shift around a turn. Equipment like the seven-post rig helps, but the ultimate test is on the track. Part of "The Science of Speed" series.
How do horseshoe crabs keep humans healthy? They have blue, copper-based blood, which quickly clots in the presence of bacterial toxins. Medical researchers use it to test intravenous drugs, vaccines, and medical devices, ensuring that they are free of bacterial contamination. Part of "The Remarkable Horseshoe Crab" series.
Presents three key concepts about chemical reactions and energy changes: exothermic and endothermic reactions, reaction rates involving temperature and concentration, and catalysts. Each concept is illustrated with a variety of experiments and computer animation to illuminate what is happening both visibly and at the molecular level.
Increasing the time of a collision from a tenth of a second to two tenths of a second can make a huge difference in the number of "G's" a driver experiences. The car, the track, the seat belts, and seat construction spread out the force of impact and save lives. Part of "The Science of Speed" series.
On the windswept tarmac of the former Alameda Naval Air Station, an inventive group of scientists and engineers are test-flying a kite-like tethered wing that may someday help revolutionize clean energy. Students explore the potential of wind energy and new airborne wind turbines designed to harness the stronger and more consistent winds found at higher altitudes.
Researchers see promise in using an off-the-shelf fabric in athletic coaching and physical therapy, and another group of scientists are studying how pyroclastic flows defy friction. Other segments include new techniques to test for viral infections and the design of a new robot. Part of the "4 Awesome Discoveries You Probably Didn't Hear About This Week" series.
Showcases innovative teaching techniques in higher education as performed by science and math professors at Hampshire College, the University of Massachusetts, and Springfield Technical Community College. Techniques include interactive learning, giving pyramid exams (a two-step exam that turns a test into an interactive learning experience), problem-based cooperative group work, using technology (as opposed to lecture), and more collaboration between colleagues.
Dr. Randall Hughes is conducting an experiment into how well black mangrove propagules from both local and south Florida trees grow in Saint Joseph Bay. Following a harsh winter, she is able to more thoroughly test the survivorship of black mangroves in northern Gulf marshes. Part of the series In "The Grass, On The Reef."
Elephants can communicate over long distances using low-frequency sounds that travel both in the air and through the ground. Scientists are studying whether elephants can hear and interpret these ground vibrations. Using amplifiers, speakers, geophones, and video cameras, scientists have designed an experiment to test how elephant herds respond to an alarm call when it is played back through the ground.
This program is devoted to the senses that bring information of more distant events. The camera shows a reckless driver careening down a road—and then takes the viewer inside his eye, where the image of the potential crash site is pictured. The camera enters the ear, showing how the linked bones vibrate in response to a sound, and by using a computer graphic sequence, shows how the eye focuses on an image.
Dr. David Kimbro and Dr. Randall Hughes investigate a new idea: can crabs hear? They design an experiment to test their new theory and explore the effects it may have on the crabs. Part of the series "In The Grass, On The Reef."
