A black hole is an object in space that cannot be seen because it sucks in everything near it, including light. It looks like a totally black area in space because no light escapes from it or bounces off it. Astronomers learn about black holes by observing the materials swirling around them and what happens to these materials. A black hole has a huge amount of gravity that pulls materials into it. A black hole can form when a big star reaches the end of its life in a supernova and explodes with the material from the supernova collapsing in on itself and falling into a tiny area.

Produktbeschreibung
A black hole is an object in space that cannot be seen because it sucks in everything near it, including light. It looks like a totally black area in space because no light escapes from it or bounces off it. Astronomers learn about black holes by observing the materials swirling around them and what happens to these materials. A black hole has a huge amount of gravity that pulls materials into it. A black hole can form when a big star reaches the end of its life in a supernova and explodes with the material from the supernova collapsing in on itself and falling into a tiny area. Having such a huge amount of material in such a small space creates a huge amount of gravity strong enough to pull whole stars into the black hole. Astronomers think that anything that gets too near a black hole will undergo a process called spaghettification in which the object is pulled into the black hole and stretched out like a piece of spaghetti until it is pulled apart. It is likely that most galaxies have a black hole at the center with all the stars and other objects circling it. Pronunciation guide included. 24 pages filled with engaging, colorful illustrations.

Autorenporträt
Dr. Rebecca Woodbury received her PhD in biophysical chemistry from the University of New Mexico in 1992. She was awarded a National Science Foundation postdoctoral fellowship in the Department of Molecular Biology at the University of New Mexico, followed by a Burroughs Wellcome Fund Postdoctoral Fellowship in the Department of Molecular Biology at the University of California, Berkeley. While home schooling her three children, Dr. Woodbury was unable to find a curriculum that provided a solid foundation in science. She left academia, and using her scientific background coupled with her love of learning, she developed a series of science books for kids. The Real Science-4-Kids curriculum provides students with a solid foundation in science and gives them the tools to evaluate scientific data on their own. "We should not rely on the 'experts' but instead learn how to critically evaluate every scientific claim," states Dr. Woodbury. "In these uncertain times with so many social, scientific, and economic problems, it is not enough to teach our kids what to learn. We must also teach them how to learn, and we must encourage our kids to learn from others. Part of learning from others is to know how to engage in productive debate." The Real Science-4-Kids curriculum, with its engaging, kid-friendly Student Textbooks; Laboratory Notebooks full of real science experiments; and easy to use Teacher's Manuals, provides kids with a solid science education in chemistry, biology, physics, geology, and astronomy. This curriculum is used in all 50 states in the US and many other countries. Dr. Woodbury and her publishing team continue to develop and test new products at the Real Science-4-Kids Albuquerque headquarters.
