Mercury is a chemical element with the symbol Hg and atomic number 80. It is commonly known as quicksilver and was formerly named hydrargyrum. It is the only metallic element that is liquid at standard conditions for temperature and pressure.

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.
Students explore the relationship between observations and measuring things in science. Specific ways of measuring length, mass, volume, and temperature are demonstrated using tools common to the classroom. Other terminology includes unit of measurement, meter stick, metric ruler, balance, graduated cylinder, and thermometer.
What is concentration? Explore the relationships between moles, liters, and molarity by adjusting the solute amount, solution volume, and changing solutes to compare different chemical compounds in water.

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.
Chemistry experiments with salts demonstrate the following: neutralization; neutral, alkaline, and acid solutions; preparing zinc sulfide and sodium chloride; and the formation of ammonium chloride.
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.
Professor Michael Sailor hopes to dramatically change how cancer is being treated. With support from the National Science Foundation, he is on a quest to create nanoparticles that travel the bloodstream, latch onto cancers in their earliest stages, and destroy them.
How can substances, such as water, exist in several dramatically different phases? Easy-to-understand examples illustrate how phase changes occur. Additional concepts and terminology include states of matter, particles, solid, liquid, gas, plasma, melting, freezing, vaporization, boiling, evaporation, condensation, and sublimation.
What's the difference between thermoplastics and thermoset plastics? The primary physical difference is that thermoplastics can be remelted back into a liquid, whereas thermoset plastics always remain in a permanent solid state. Part of the "Ask a Scientist" series.
In this episode, Dr. Fus from Ohio State University discusses some of his science experiments. He also explains the chemistry behind some chemical reactions. As a finale, Dr. Fus demonstrates his "elephant toothpaste" experiment.
One of the fifteen parts of the "Farm to Market" series. Bees gather nectar from flowers and use it to make honey. Demonstrates bee behavior, beekeeping, honey harvest, and packaging. Follows the process from start to finish, including footage of bees inside their hive.
Experiments demonstrate the electrolysis of copper sulfate and the factors leading to corrosion. Other demonstrations focus on the chemical reactions of iron nails in water, sulfuric acid, sodium hydroxide, sodium chloride, and air.
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 different states of matter. Part of the Science Video Vocab Series.
Dr. Chris races against the clock after a policeman’s pet is deliberately poisoned. Also, the clinic takes in a malnourished penguin after severe storms wash it ashore, and a seven month old puppy faces a scary operation after a run in with a car.
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 what it means for substances to freeze. Part of the Science Video Vocab Series.
Part of the "Chemistry in Action" series. Chemicals interacting with each other are one of the most fascinating topics in chemistry. Fireworks, burning flares, and rusting all illustrate chemical reactions. Describes the different types of reactions as well as the process of balancing chemical equations. Introduces the following terminology: chemical equations, Law of Conservation of Mass, decomposition and synthesis reactions, replacement reactions, and reaction rates.
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.
Matter is made up of tiny particles called molecules. Host, Max Orbit, helps students learn all about the different properties, qualities, and characteristics of matter. He also discusses solids, liquids, and gases. Part of the "Way Cool Science" series.
