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 chemistry. Part of the Science Video Vocab Series.
Nate explores the "Chemistry of Color" exhibit at the Indianapolis Museum of Art to find out more about color and pigments. The exhibit charts the relationship between chemistry and art over a period of more than 4,500 years. Part of the "Artrageous With Nate" series.
Since the beginning of time, humans have used chemical reactions without understanding them. For example, ancient Greek artisans were able to smelt metal, dye fabrics, and make glass. The attempt to transform simple metal into gold and silver was known as alchemy (the forerunner of chemistry as we know it today). By mixing elements, alchemists created chemical reactions which produced new compounds. While alchemists were never able to transform anything into gold or silver, their trails helped shape the science of chemistry. Part of Chemistry: Solved by Sherlock Olmos Series.
The state of matter is the form taken by matter at a given temperature and pressure. A phase of matter is uniform with respect to its physical and chemical properties. Matter undergoes phase transitions to change from one phase to another. Part of the "Chemistry" series.
The formation of molecular bonds is an essential part of keeping matter together. The sharing of charges between atoms helps them become more stable. Other topics covered include sharing electrons, bonding tendencies, isomers, VSEPR theory, and molecular geometry. Part of the "Chemistry" series.
Thermodynamics deals broadly with the conservation and conversion of various forms of energy. It also describes the relationships between energy and the changes in properties of matter. Other topics covered include Hess's law, the laws of thermodynamics, and the Gibbs free energy. Part of the "Chemistry" series.
A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. Topics covered include precipitation reactions, oxidation-reduction reactions, kinetics, equilibrium, and nuclear reactions. Part of the "Chemistry" series.
Solutions are classified as acidic or basic based on their hydrogen ion concentration relative to pure water. An acidic solution has a higher concentration of hydrogen ions, and a basic solution has a lower concentration of hydrogen ions. Other topics covered include chemical reaction basics, properties of acids and based, acid-base reactions, and other mixtures. Part of the "Chemistry" series.
A solution is a homogeneous mixture of two or more substances. It contains a solute and and solvent. Solubility is the maximum quantity of a solute that can be dissolved in a given amount of solvent at a specified temperature. Other topics covered include concentration, Raoult's law, colligative properties, and non-ideal behavior. Part of the "Chemistry" series.
Using a balanced chemical equation to calculate amounts of reactants and products is called stoichiometry. It is a super technical-sounding word that simply means using ratios from the balanced equation. Topics covered in this program include the metric system, balancing equations, molar conversions, mass percent, empirical formulas, and limiting reactants. Part of the "Chemistry" series.
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.
Tests the heat zones of a Bunsen burner and shows some elements' coloration when placed in the flame. Notes that chemistry is everywhere, in both natural and man-made components.
What the microscope did to unlock the secrets of biology, the chemiscope is intended to do, to revolutionize chemistry. The ultimate goal is to observe chemistry in the act, to see the making and breaking of bonds in real-space and real-time. Part of the National Science Foundation Series “Science Nation.”
What makes a glow stick glow? And why doesn't it heat up from the light? The answer lies in the processes taking place during chemiluminescence.
The rate of a chemical reaction is affected by a number of factors, including temperature and the concentration of reactants at the beginning of the reaction. While the chemical equation may show reactants turning into products as a straightforward process, it is actually involved and precise. How exactly do reactants turn into products? Sometimes, the answer is as simple as two atoms bumping into each other and forming a bond. Most of the time, however, the process is much more complex. Controlling the rate of reactions has implications for a variety of applications, including drug design and corrosion prevention. Part of the series Chemistry: Challenges And Solutions.
The endocrine system maintains the body's delicate chemical balance. Describes the location, function, and effects of the major endocrine glands, and notes their close relationship to the nervous system. Some discussion of diabetes and hormonal imbalances.
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.”
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.”
Solar panels are becoming a familiar site in communities across the United States, but what about solar fuels? A solar fuel is produced from sunlight through artificial photosynthesis, mimicking what Mother Nature has been doing for billions of years. Many chemists and chemical engineers are working to make solar fuels a viable option in the future. Part of the National Science Foundation Series “Science Nation.”
