Although the first real unifying theory of chemistry was developed in the late 17th and early 18th centuries, the 20th century saw many advances in this field as well. From its Asian and Arabic roots in mystical and spiritual alchemy to the creation of nanochips for computers, the field of chemistry has come a long way in scientific discovery.

Presenting 20 new and innovative full-color science projects in a clear, easy-to-understand style, the new Chemistry Experiments gives middle and high school students a firm grasp on this branch of science in a fun, hands-on way. Topics covered include ozone depletion, wood alcohol, heat energy, purifying water, and levels of sugar.
