From Greek Atoms to Quarks: Discovering Atoms

Gr 6–9— These titles link discoveries and inventions to earlier and contemporaneous ones, revealing the "chain reactions" that are often involved in advancements in technology and in knowledge. Ballard defines energy and its sources and traces its development from steam in the Industrial Revolution to nuclear energy and subatomic particles. Morgan tells the story of the atom, including its discovery, structure, power, and future in subatomic particles. In the third book, she focuses on alternative energy sources and includes wind, solar, water, nuclear, geothermal, biopower, and fuel-cell technologies. Archival and full-color photos and reproductions appear on nearly every page. Solid presentations.—Michael Giller, South Carolina Governor's School for the Arts and Humanities, Greenville
