Essential to life, water can be found in different forms all around us. This important book explains how the Earth's supply of water moves from bodies of water, to the atmosphere, and to land in a process called the water cycle . Accessible text and detailed images help explain such processes as transpiration, evaporation, condensation, and precipitation, as well as the important roles of sunlight and gravity in the water cycle. Feature boxes highlight examples of the ways in which human activity creates shortages of clean water and interferes with the water cycle. Readers are encouraged to find ways to take action and find solutions.

Albert Einstein was a theoretical physicist and an intellectual giant of the twentieth century. This fascinating biography reveals Einstein's life story, and how his theories changed the way we looked at the universe. Born in Germany in 1879, Einstein focused his studies on science and mathematics. He won a Nobel Prize in Physics and was instrumental in persuading U.S. President Roosevelt to pursue the development of the atomic bomb in World War II. Einstein published hundreds of research papers, articles, and books and lectured at universities in Europe and the United States until his death in 1955. Einstein's name is synonymous with genius, and, not surprisingly, his brain has been preserved for study.

Before they spearheaded the musical phenomenon called "the British Invasion," John Lennon, Paul McCartney, George Harrison, and Ringo Starr were just four kids from Liverpool. Throughout the 1960s, however, they embodied, as the Beatles, the musical, artistic, social, and spiritual promise of an entire generation. After their stormy breakup in 1970, the Fab Four became four solo artists, at times even appearing on each other's recordings. In addition to the millions of records each band member has sold on his own since their breakup, more than 40 Beatles compilation albums have been released and continue to sell millions of copies. To this day, more than one billion Beatles recordings have sold, and thousands of books, academic papers, blogs, and websites are dedicated to the group. Despite being the Beatles for only a decade, John, Paul, George, and Ringo together formed the most successful - and arguably the most influential - musical group in history.

Readers will discover that the natural element carbon is found in all living things, including people. This fascinating book explains how the Earth's supply of carbon moves among Earth's oceans, atmosphere, ecosystem, and geosphere in a process called the carbon cycle. Accessible text and detailed images help explain such processes as photosynthesis, respiration, and decomposition. Feature boxes highlight examples of the ways in which human activity, such as burning fossil fuels, releases too much carbon dioxide into the air disrupting the balance of the carbon cycle. Readers are encouraged to find ways to take action and find solutions.
