Chemistry

March 21, 2016
A timeline that stretches from the speculated existence of atoms by the Greek philosopher Democritus to the 2010 discovery of the element ununseptium greets readers at the beginning of this addition to the Inquire and Investigate series. Mooney offers a thorough overview of what chemistry is and why it matters, in chapters exploring atoms, states of matter, compounds, chemical reactions, and more. Sidebars define terms and explain concepts like density and scientific notation; reader-directed questions and QR codes that link to online resources provide opportunities for outside discussions and investigation. Comics sequences featuring an adult scientist and three students offer breaks from the extensive information provided, while the dozen or so experiments let readers learn about condensation, test for acidic and basic properties, and create a battery from a lemon. Ages 12–15.

Gr 6-9-This title introduces readers to the wonders of chemistry and its far-reaching effects on our lives, from the carbonation in soda to nuclear reactions. A time line at the beginning of the book highlights scientific discoveries from the introduction of the idea of matter in the form of particles by Democritus in 460 BCE to the discovery of a new element in 2010. Each chapter explains an aspect of chemistry such as atoms, states of matter, compounds, and reactions. An "Inquire and Investigate" section in each chapter offers problems to solve and experiments to try. QR codes placed throughout lead to primary sources on the Internet. Those with a science bent will find the information easily accessible and concise, while those with little interest will be drawn to the colorful graphic illustrations and highlighted sidebars. The experiments provided will inspire and encourage further discovery of the world of science. VERDICT An additional purchase where science materials are in demand.-Denise Moore, formerly at O'Gorman Junior High School, Sioux Falls, SD
