What will the weather do today? In this book, readers in grades 4-9 will learn about ways people have developed to predict the weather, from looking at the sky to running models on a computer. Temperature, pressure, and wind speed are among the factors that determine whether to look out for sunshine or a tornado. Weather prediction not only helps you plan your day, it can even save lives! This series features a variety of science topics aligned to NGSS standards. From mixing matter to the study of sound waves, each informative book includes a glossary, comprehension questions, and an activity for home or the classroom.
