World of Chemistry, The
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.
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. CC
10. Signals from Within — Chemists’ knowledge of the interaction of radiation and matter is the basis for analytical methods of sensitivity and specificity. CC
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
