Description
Introduces young readers to the science of chemistry through a series of step-by-step guided experiments they can do safely, if a little messily, in their backyards, including making a geyser out of mint candy and soda, giant bubbles with dish soap, cornstarch, glycerin, and baking powder, and making bricks out of mud, grass, and an egg carton. Includes a glossary.

Description
In a series of fun and involving hands-on chemistry experiments, kids learn how and why a volcano erupts, why there are holes in bread slices, why pennies turn green, how to separate milk into its solid and liquid parts, and how to grow fluffy white crystals. They will also determine and demonstrate how air is cleaned by absorbent chemicals, how to change hydrogen peroxide into water and oxygen with the help of a potato, and how and why evaporation...

Description
An explanation of how a mass spectrometer works is followed by a demonstration of a mass spectrometer in action. The analysis of simple mass spectra is discussed-simple splitting of hydrocarbons, the effect on splitting of heteroatoms in alcohols and ethers, and the McLafferty rearrangement. Discussion of the spectra of isotopic mixtures, such as chlorine and bromine, and the use of accurate masses is also included.

Description
An explanation of the theory of infrared absorption is followed by showing a series of spectra demonstrating the major absorption peaks. Shifts within the carbonyl group, and their explanation, are discussed. The N.M.R. portion of the program covers the ideas of integration, chemical shift, and splitting in proton spectra in a logical process of development of the subject.
