It had an illustration that captivated him–a diagram showing Earth’s interior as it would look if you cut into it with a large knife and removed about a quarter of its bulk. The idea of lots of startled cars and people falling off the edge of that sudden cliff (and 4,000 miles is a pretty long way to fall) was what grabbed him in the beginning, but gradually his attention turned to what the picture was trying to teach him: namely that Earth’s interior is made up of several different layers of materials, and at the very centre is a glowing sphere of iron and nickel, as hot as the Sun’s surface, according to the caption. And he very clearly remembers thinking: “How do they know that?”Bill’s storytelling skill makes the “How?” and, just as importantly, the “Who?” of scientific discovery entertaining and accessible for all ages. He covers the wonder and mystery of time and space, the frequently bizarre and often obsessive scientists and the methods they used, and the mind-boggling fact that, somehow, the universe exists and against all odds, life came to be on this wondrous planet we call home.

     The National Aeronautics and Space Administration, better known as NASA, began in 1958. With its creation, the United States hoped to ensure it won the space race against the Soviet Union. Author Sarah Fabiny describes the origins of NASA, the launching of the Apollo program that landed the first human on the moon, and the many missions and discoveries that have taken place since then. NASA has a rich history and still plays an important role in uncovering the mysteries of the universe. Readers are sure to get sucked into this book.

    Born in Pisa, Italy, in the sixteenth century, Galileo contributed to the era's great rebirth of knowledge. He invented a telescope to observe the heavens.

ATTENTION, PARENTS: Yes, your kids may need your help with a few experiments. And yes, sometimes it may get a tad messy. But it’s not pure mayhem. The balloon rocket whizzing through the garden? It demonstrates Newton’s Third Law of Motion. That chunk of potato launched across the kitchen from a tube? Welcome to Boyle’s Law. Every experiment demonstrated real science, at its most memorable.

    For thousands of years, humans believed that Earth was at the center of the Universe, but all of that changed in the 17th century. Astronomers like Nicolaus Copernicus, Galileo Galilei, Johannes Kepler, and Isaac Newton proposed the unthinkable theory that Earth and the other planets actually revolved around the Sun. This engaging book chronicles the beginning of the modern age of astronomy, then follows later discoveries, including NASA's current missions in space.
