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.

Organics are carbon-based molecules and key ingredients to life. Scientists want to know if organics can be found on Mars. However, finding organics is difficult because they easily break down when exposed to harsh things like extreme radiation and chemical oxidants. These broken down particles give the Martian surface its rusty color. Part of the “Mars in a Minute” series.
Learn how organic farmers diversify their crops and control pests with natural enemies in order to farm without chemicals. Viewers also explore the economics and impacts of traditional and organic farming. Part of "The Botany of Desire" series.
What happens to waste after it is discarded? Treating discarded waste consumes many resources and hours of man power. A walk through the facilities of CEAMSE reveals what happens to discarded items and the residue they leave behind.
How does organic farming differ from other methods? A team explores soil conditions, water availability, climate, and different techniques.
Part of the "Green Careers" series. Provides an inside look at an organic farm and an organic retail store. Discusses the daily challenges and rewards of working in this field. Organic farming includes a wide range of jobs in production, marketing, and distribution. Jobs profiled include the following: farm manager, retail sales manager, and organic produce buyer.
Human beings, like every living organism, are driven by two inherent needs: to survive, and ultimately, to reproduce. To accomplish the goals of survival and reproduction, we have inherited bodies crafted by evolution so that every individual human organism is an organic super factory, a living machine made up of systems that process fuel, build products, repair damage, expel waste, and defend against invaders. Introduces the complex physiological systems of the human body: muscular movement, digestion, circulation, respiration, nerves, glands, immunity, and reproduction. Also, illustrates and explains the cellular basis of life and the importance of carbon in organic chemistry.
Think of earthworms and a few things come to mind: they make great bait for fishing, they aerate the soil, and they’re an excellent addition to a compost pile. But, what a lot of people don’t know is many earthworms are actually invasive species. Earthworms may be small but when they take over a forest, the impact is dramatic. They cause the rapid incorporation of organic material into the soil, changing its structure, chemistry and nutrient dynamics. What's known as the duff layer is suddenly removed, and this duff, or decaying organic material on the forest floor, is habitat for several species of insects, spiders, small vertebrates, bacteria and fungi. It is also the primary rooting zone for most plants.
Focuses on organic chemistry experiments that demonstrate the preparation and properties of ethanol. Additional experiments review ethyne (acetylene), and naphthalene.
This UNC TV segment explores the intricate interactions between organisms which are the building blocks of the freshwater ecosystem. These include the relationships between insects and the environment, predator and prey, water and organic waste, and nutrients and underground channels.
In this episode, Pinky and Petunia explain the organic compound ATP. It provides the energy to living organisms that drives the many processes in cells. Part of "The Amoeba Sisters" series.
Part of the "Visualizing Cell Processes" series. Includes the following modules: "The Cell Machinery," "A Variety of Cells," "Organic Molecules: The Building Blocks of Life," "Prokaryote Evolution and Diversity," and "Independently Living Eukaryotic Cells."
At Lake Seminole Farm, David Krause and Breck Dalton discuss mushroom production and their role in forest ecology. They grow organic shiitake and oyster mushrooms on trees found in the forest. Part of the "EcoAdventures in North Florida" series.
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.
Carbon is the basis of all organic molecules. It is also one of the most abundant elements in the universe. This video segment illustrates the special characteristics of carbon that make it an essential ingredient for life.
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.
Will we be able to grow all of our fuel in the future? Uncovers a biofuel jet truck, a record-breaking flying machine, and a unique car made almost entirely of organic matter. Also, explores new ways of harvesting energy from biomass.
Part of the "Chemistry in Action" series. Demonstrates how chemical compounds are placed into groups so that they may be studied easier. Explores acids and bases, emphasizing their nature and common everyday uses. Discusses carbon compounds, and introduces the following terminology: acid, base, pH, salt, carbon, organic, and hydrocarbon.
It was once believed that organic compounds, light, and water were needed to sustain life, but life has been found in complete darkness underwater. National Geographic Explorer Bob Ballard discovered Lost City, an underwater mountain range, and it is teaming with life. Segment of a video from Wild Chronicles Series.
Nourish is an educational initiative designed to open a meaningful conversation about food and sustainability, particularly in schools and communities. In this clip, farmer Nigel Walker discusses the skills needed to be a productive worker in the agricultural fields. Part of the Nourish Short Films Series.
