Authentic archival illustrations and photographs are used to bring 19th Century medical advancements to life. The film notes key figures from Louis Pasteur, Robert Koch and Joseph Lister to Florence Nightingale, Elizabeth Garrett, Octavia Hill,...Show More

Accuracy

The royal archery contest begins! Everyone expects Robin Hood to win, since he is an accurate and reliable archer. But what do the terms accuracy and reliability mean? This lesson will explore accuracy and systematic errors, including how to...Show More

Acids and Bases

Acids are sour in taste, while bases are bitter in taste and feel soapy. Acids and bases are present in a variety of things around us.

Acids and Carbonates

In this episode, we describe what carbonates are and explain how they react with acids. If it wasn't for carbonates, our own stomach acid would kill us, acid rain would have destroyed our forests, and—worst of all—our pancakes wouldn't be as...Show More

Acids in Industry

In Acids in Industry, we look at what acids are, how they're made, and how they're used in steel making and agriculture. We also take a quick trip back to the 1770s to look at how acids were used by Captain James Cook to save his crew from the...Show More

Addition Reaction of Carbon Compounds

An addition reaction involves a combination of two or more reactants, like ethyne and hydrogen, to form a single product, like ethane. Addition reactions are a characteristic property of unsaturated hydrocarbons.

Adenovirus after 24 Hours

Penetrating the cell's defences, learn about how a virus develops in the nucleus after 24 hours.

Adenovirus Entry

It can be inhaled from a simple sneeze. Discover how adenoviruses attack the cell.

Adenovirus: Journey to the Nucleus

Follow the adenovirus as it journeys to its destination - the nucleus.

Advanced Acid-Base Chemistry

In this episode, we take a deeper look at pH and explain how the numbers on the pH scale are actually related to the number of H⁺ or OH⁻ ions present in an acid or a base. We then descend even deeper down—to the atomic level—to explain...Show More

Alchemy to the Birth of Chemistry

Deep within the vaults of London's Royal Society, learn about the history that birthed the world's first chemist.

Application of Colloids in Everyday Life

Colloids are heterogeneous mixtures. Colloids play a very important role in our daily lives. Some examples of colloids which we use in our daily lives are - milk, cheese, medicines like antibiotics, milk of magnesia, and solutions soap and detergent.

Atomic Absorption Spectrophotometry

Chemical analysis is integral to modern society. The testing of consumer goods, industrial products and food relies upon a number of different techniques. This program will investigate the analytical techniques of chromatography, mass...Show More

Atomic Hook-Ups: Types of Chemical Bonds

Atoms are a lot like us - we call their relationships "bonds," and there are many different types. Each kind of atomic relationship requires a different type of energy, but they all do best when they settle into the lowest stress situation possible.

Avogadro's Law

In 1811, Amedeo Avogadro studied the relationship between volume of a gas to the number of molecules at constant temperature and pressure. This relationship known as Avogadro’s law. Avogadro’s law states that, ‘At constant temperature and...Show More

Blueprints for the Cell's Destruction

In its initial entry into the cell, the adenovirus begins to destroy the nucleus.

Bohr's Model of the Atom

This programme focuses on Neils Bohr, who worked with some of the best physicists of the 20th century to devise his atomic model. Students will gain an understanding of the historical developments in atomic theories up to Bohr, a brief outline of...Show More

Bond Another Day

In a secret location, Copper and Silver separate Chlorine from Potassium. Gold and Chlorine return to Carbon’s secret school – but cannot find Fluorine and Oxygen. Carbon appears, and Gold and Chlorine flee to a nearby bond shop where they...Show More

Bonding in Carbon Compounds

Carbon is a versatile element. Its tetravalent nature, to form strong covalent bonds and the property of catenation enables it to form a large number of compounds.

Buffers: The Acid Rain Slayer

In this episode, Hank talks about how nutty our world is via Buffers! He defines buffers and their compositions and talks about carbonate buffering systems in nature, acid rain, pH of buffers, and titration. Plus, a really cool experiment using...Show More
