Australia is a land of extremesfrom the bustling city of Sydney to the wild lands of the outback. Learning about this land allows readers to explore important topics in both social studies and math curricula. As they read, they use fun facts and stats to solve math problems, which can then be checked with a comprehensive answer key. Readers also explore colorful maps of the continent that are designed to enhance their geography skills. Colorful photographs of life in Australia are presented in an eye-catching way designed to hold the interest of readers.

Simple text and illustrations introduce the basic concepts associated with graphing.

Discusses the mathematics surrounding butterflies and moths.

"From teleportation and space elevators to alien contact and interstellar travel, science fiction and fantasy writers have come up with some brilliant and innovative ideas. Yet how plausible are these ideas--for instance, could Mr. Weasley's flying car in Harry Potter really exist? Which concepts might actually happen--and which ones wouldn't work at all? Wizards, Aliens, and Starships delves into the most extraordinary details in science fiction and fantasy--such as time warps, shape changing, rocket launches, and illumination by floating candle--and shows readers the physics and math behind the phenomena. With simple mathematical models, and in most cases using no more than high school algebra, Charles Adler ranges across a plethora of remarkable imaginings, from the works of Ursula K. Le Guin to Star Trek and Avatar, to explore what might become reality. Adler explains why fantasy in the Harry Potter and Dresden Files novels cannot adhere strictly to scientific laws, and when magic might make scientific sense in the muggle world. He examines space travel and wonders why it isn't cheaper and more common today. Adler also discusses exoplanets and how the search for alien life has shifted from radio communications to space-based telescopes. He concludes by investigating the future survival of humanity and other intelligent races. Throughout, he cites an abundance of science fiction and fantasy authors, and includes concise descriptions of stories as well as a glossary of science terms. Wizards, Aliens, and Starships will speak to anyone wanting to know about the correct--and incorrect--science of science fiction and fantasy"--.

"Fun pictograms and infographics about planet Earth make learning about math topics such as volume, scale diagrams, division, and number lines easy and fun. In this book, readers go on a mission to protect threatened areas around the world and use their mathematical skills to measure geysers, protect forests, and check on glaciers. Math puzzles and exercises help children build confidence in their math skills."--.
