The World of Chemistry
Take
your class inside a single atom — then watch as billions of
atoms react explosively! The World of Chemistry explores the foundations
of chemical structures and behavior using effective computer-generated
simulations, interviews with distinguished scientists, and fascinating,
highly reactive experiments and demonstrations that are often beyond
the scope of a high school lab. Students will also visit industrial
and research labs nationwide to observe the application of chemistry
in everything from cosmetics to genetics.
Episode Descriptions
1
The World of Chemistry — The relationships of chemistry
to the other sciences and to everyday life are presented.
2 Color — The search for new colors in the mid-1800s
boosted the development of modern chemistry.
3 Measurement: The Foundation of Chemistry — The distinction
between accuracy and precision and their importance in commerce
and science are explained.
4 Modeling the Unseen — Models are used to explain phenomena
that are beyond the realm of ordinary perception.
5 A Matter of State — Matter is examined in its three
principal states--gases, liquids, and solids; relating the visible
world to the submicroscopic.
6 The Atom — Viewers journey inside the atom to appreciate
its architectural beauty and grasp how atomic structure determines
chemical behavior.
7 The Periodic Table — The development and arrangement
of the Periodic Table of Elements is examined.
8 Chemical Bonds — The difference between ionic and
covalent bonds are explained by the use of scientific models and
examples from nature.
9 Molecular Architecture — The program examines isomers
and how electronic structure of a molecule's elements and bonds
affects its shape and physical properties.
10 Signals from Within — Chemists' knowledge of the
interaction of radiation and matter is the basis for analytical
methods of sensitivity and specificity.
11 The Mole — Using Avogodro's law, the mass of a substance
can be related to the number of particles contained in that mass.
12 Water — The special chemical properties of water
are explored, along with the need for its protection and conservation.
13 The Driving Forces — Endothermic and exothermic reactions
are investigated and the role of entropy is revealed.
14 Molecules in Action — Observing molecules during
chemical reactions helps explain the role of catalysts. Dynamic
equilibrium is also demonstrated.
15 The Busy Electron — The principles of electrochemical
cell design are explained through batteries, sensors, and a solar-powered
car.
16 The Proton in Chemistry — Demonstrations explain
pH, how it is measured and the important role of acids and bases.
17 The Precious Envelope — The earth's atmosphere is
examined through theories of chemical evolution, ozone depletion,
and the greenhouse effect are explained.
18 The Chemistry of the Earth — Silicon, a cornerstone
of the high-tech industry, is one of the elements of the earth highlighted
in this program.
19 Meatless — Malleability, ductility, and conductivity
are examined, along with methods for extracting metals from ores
and blending alloys.
20 On the Surface — Surface science examines how surfaces
react with each other at the molecular level.
21 Carbon — The versatility of carbon's molecular structures
and the enormous range of properties of its compounds are presented.
22 The Age of Polymers — How chemists control the molecular
structure to create polymers with special properties is explored.
23 Proteins: Structure and Function — The program examines
proteins--polymers built from only 20 basic amino acids.
24 The Genetic Code — The structure and role of the
nucleic acids DNA and RNA are investigated.
25 Chemistry and the Environment — Dump site waste management
demonstrates chemistry's benefits and problems.
26 Futures — Interviews with leaders from academia and
industry explore the frontiers o
