Widely regarded as the father of modern genetics, Austrian friar and scientist Gregor Mendel discovered that inherited traits do not blend together, as people once believed. By cultivating thousands of pea plants in his monastery garden and statistically analyzing the results, he was the first to determine how genes (which he called "heredity factors") function, and he coined the terms "dominant" and "recessive." This title traces the amazing ...

This "particle" of light energy and its discovery revolutionized our understanding of subatomic physics and led to the theory of quantum physics. Through this new book, readers will learn about these minute packets of electromagnetic radiation and the scientists such as Max Planck and Albert Einstein, who figured out how they work.

The electron is the lightest stable subatomic particle that carries a negative charge, the basis of electricity. This new high/low book explains the inner workings of the electron as well as its discovery in 1897 by British physicist J. J. Thomson, and how that discovery led to the eventual model of the structure of the atom.

The neutrino, with no electric charge and little or no mass, is the most elusive subatomic particle of them all. Only 1 in 10 billion reacts with a proton or neutron. This book is sure to enlighten those curious about this unique subatomic particle and its importance in explaining the Sun's energy.

Do you love to watch WX Geeks on The Weather Channel? This how-to book for junior meteorologists is co-written by WX Geeks host Dr. J. Marshall Shepherd along with award-winning children's science author Dr. Fred Bortz. The two show kids how to predict the weather in their own backyards using simple, inexpensive, self-built meteorological instruments that add up to a fully operational weather station. Based on Shepherd's state science fair win...

Are we alone in the universe? Is Earth the only planet that's a suitable home for life? These questions have long motivated scientists as central issues in astrobiology, the search for life in the universe. Astrobiologists compare life on Earth to signs of life on other planets. They test meteorites for evidence of alien bacteria. They collect soil and atmospheric samples from other planets. They study photographs taken on space missions. And ...

As space exploration advances, scientists develop technologies to observe, record, and use information gained in those explorations. This book looks at seven modern space technology wonders--the Great Observatories (orbiting telescopes such as Chandra X-Ray Observatory), the International Space Station, Earth-observing satellites used in GPS tracking, weather tracking, communications, and other applications, technology used in the search for l...
