Every child who performs these 50 fabulous feats will feel like a magician--but the magic here is really science at play. Every trick in the book has a sound, easy-to-understand scientific explanation that will stimulate kids’ understanding of basic concepts. Even as they’re having fun, children will wow the crowd by poking a skewer through a balloon without making it pop, or balancing a penny on a coat hanger. Nothing’s cooler than watching a real egg get sucked into a glass bottle, picking up ice without even touching it, or whipping up fizzy and colorful solutions that any mad scientist would prize. Wild optical illusions will boggle the mind and astound the eye.
Get kids interested in science while making toys and doing magic tricks with the unique experiments in this book. Make a "genie" in a bottle, a flame that jumps, a toy electric motor, and more. Readers will learn chemistry and physics while having fun. Many experiments include high-interest ideas to get young people involved in science fairs. Students can ace their next science project or test using magic and toys.
What is friction? What is the coriolis force? Young scientists will explore the physics of forces and motion with the great experiments in this book. Full-color illustrations highlight key points to make science a snap. Many experiments are followed by ideas for science fair projects. Help students ace their next physics project or test.
"Learn about air pressure, the laws of gravity, optical illusions and more"--
Help students develop and practice the skills they need to compare and contrast fiction and nonfiction passages. After each of the 25 pairs of passages, students are asked both multiple choice and open-ended questions.
The fundamental question of how an undifferentiated progenitor cell adopts a more specialized cell fate that then contributes to the development of specialized tissues, organs, organ systems and ultimately a unique individual of a given species has intrigued cell and developmental biologists for many years. Advances in molecular and cell biology have enabled investigators to identify genetic and epigenetic factors that contribute to these processes with increasing detail and also to define the various molecular characteristics of each cell fate with greater precision. Understanding these processes have also provided greater insights into disorders in which the normal mechanisms of cell fate ...
This exceptional collection provides new insight into the life of North Carolina writer and activist Paul Green (1894-1981), the first southern playwright to attract international acclaim for his socially conscious dramas. Green, who taught philosophy and drama at the University of North Carolina at Chapel Hill, won the Pulitzer Prize in 1927 for In Abraham's Bosom, an authentic drama of black life. Among his other Broadway productions were Native Son and Johnny Johnson. From the 1930s onward, Green created fifteen outdoor historical productions known as symphonic dramas, thereby inventing a distinctly American theater form. These include The Lost Colony (1937), which is still performed toda...
