Scientific research is about questions and observations. It is the process of discovery; it strives for facts and conclusions unencumbered by bias, distortion, and political sensibilities. Although sometimes the methods and motivations are flawed, science attempts to develop a body of knowledge that can guide decision makers, enhance daily life, and lay a foundation for future generations. The Inside Science series provides students with a sense of the painstaking work of scientific researchùwhether it involves microscopic cells cultured in a lab or identifying planets far beyond the solar system. It examines how scientists work and where that work leads them. Through clear and vivid narrative, carefully selected anecdotes, and direct quotes each book in the series reinforces the role of scientific research in furthering learning and creating a more livable world.
