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.

Experiments illustrate the presence and properties of: 1) saccharides (glucose and starch) in fruits and vegetables; 2) lipids (fats) in nuts and vegetable oils; and 3) proteins in eggs, meat, and milk. Emphasizes that chemistry is all around us.
A team conducts different experiments with food substances to show the chemical reactions that take place when exposed to air, heat, or extreme cold. They provide a close up on cooking technology and food chemistry from the kitchen of a restaurant. Part of Invisible Science and Technology Surrounding Series.
Cosmetics are big business. They are used by almost every person walking on the Earth. Shows how cosmetics are made and how they have been used for thousands of years. Outlines bases, bulking agents, coloring agents, fragrances, and preservatives. Demonstrates the making of an emulsion and explains the processes of distillation or solvent extraction.
Sherlock Olmos uses his famous detective skills to solve his mysterious case of how the periodic table is structured. With a touch of humor, he investigates electrons, valences, and the physical and chemical properties of some of the elements. Part of Chemistry: Solved by Sherlock Olmos Series.
Very little in the physical world around us occurs without chemical reactions being involved. Takes an in-depth look at five common products that are in use all around us. Also, explores the chemistry behind their manufacture and/or use, including chemical equations. The products are soap, polystyrene, aluminum, paint, and car batteries.
Sherlock Olmos decides to dig deeper into dark corner of this great house to investigate the suspicious behavior of some chemical elements. The exchange of electrons and the characteristics of hydrogen, fluorine gas, and the noble gases are the primary subjects of his investigation. Part of Chemistry: Solved by Sherlock Olmos Series.
Part of the "Chemistry in Action" series. Describes and illustrates the process of chemical bonding through live action footage and animations. Provides an overview of the role atomic structure plays in the process of bonding. Provides examples of how chemical bonding, including ionic bonds, covalent bonds, and metallic bonds, affects the characteristics of matter. Introduces the following terminology: element, atomic structure, energy level, valence electrons, ionic bonds, crystal lattice, covalent bond, and metallic bond.
Researchers explore how different types of biomass can be used to produce fuel. One researcher is building reactors to grow algae used to create biofuel. A different study examines how leafcutter ants break down biomass in order to convert cellulose in plants to a fermentable sugar used to make ethanol. Finally, an engineer uses chemistry and heat to turn sawmill waste into bio-oil and gasoline.
Are humans the accidental products of an uncaring universe? Or are they the beneficiaries of a cosmic order that was planned beforehand to help them flourish? This documentary explores growing evidence from physics, chemistry, biology, and related fields that our universe was designed for large multi-cellular beings like ourselves. Geneticist and author Michael Denton investigates the special properties of carbon, water, and oxygen that make human life and the life of other organisms possible.
Science laboratories present a whole range of potential hazards to people's health and well-being, and it is critical that both teachers and students are fully aware of their responsibilities to ensure the learning environment is kept safe at all times. Aims at viewers who are not new to science laboratories. Covers a range of safety areas, including general safety in these laboratories and specific areas of potential risk in chemistry, biology, and physics labs.
As scientists discovered more and more chemical elements, they began developing systems to organize the elements by their chemical properties, leading to the modern periodic table. Through its organization, the periodic table makes clear the underlying chemical and physical trends among the elements. The periodic table is being continually updated even today as scientists strive to create new elements in laboratories. Part of the series Chemistry: Challenges And Solutions.
Beginning with Alchemy's attempt to find the recipe for gold, scientists have strived to unearth the basic building blocks of our world. These building blocks became smaller and smaller as scientists including Isaac Newton and Albert Einstein studied the world. From elements, to the atom, to subatomic particles, the study of our natural world has led to inventions both deadly and fantastic, including X-Rays, MRIs, calculus, and the atomic bomb.
To manipulate chemical reactions on a large scale, scientists use stoichiometry to quantify those reactions. The use of stoichiometry ensures there are the right amount of reactants and products. Without it, reactions can be incomplete, with expensive materials wasted and harmful byproducts created. Using stoichiometry, scientists are creating chemicals that take the place of petroleum in fabricating sustainable materials. At a different lab, scientists are mimicking the process of photosynthesis to convert the sun’s energy into storable chemical energy. Part of Chemistry: Challenges and Solutions Series.
Some chemical reactions happen spontaneously, like metal rusting. Other reactions are non-spontaneous and need to absorb energy in order to occur. Using the Second Law of Thermodynamics, the principle of entropy, and the calculation of Gibbs free energy, scientists can predict which reactions will occur and vary the conditions to make more of the desired products. In equilibrium reactions, both products and reactants are always present. Equilibrium reactions in the human body are essential for life and can be exploited in chemical manufacturing as well. Part of the series Chemistry: Challenges And Solutions.
Using light as a probe, scientists found innovative ways to make inferences about the inner structure of the atom. In this unit, scientists discuss the change from believing the atom was a single indivisible particle to later understanding the atom is composed of subatomic parts. This new picture of matter lead to the development of the quantum model of the atom, as well as ways to identify traces of chemical elements, whether on earth, in the sun, or in a distant galaxy. Part of the series Chemistry: Challenges And Solutions.
Human babies drink milk; it's the food especially provided for them by their mothers. Various cultures have also added the milk of other mammals to their diet, and adults think nothing of downing a glass of cows' milk. But worldwide, only a third of adults can actually digest lactose, the sugar in milk. Human geneticist Spencer Wells tracks down the genetic changes associated with the ability to digest lactose as adults. Combining genetics, chemistry, and anthropology, this story provides a compelling example of the co-evolution of human genes and human culture.
As scientists delved deep into the atom, into the very heart of matter, they unraveled nature's most shocking secrets. They had to abandon everything they believed in and create a whole new science, which today underpins the whole of physics, chemistry, biology, and maybe even life itself. Tells a story of great geniuses, like Albert Einstein and Werner Heisenberg who were driven by their thirst for knowledge and glory. It's a story of false starts and conflicts, ambition, and revelation, a story which leads us through some of the most exciting and exhilarating ideas ever conceived of by the human race.
