Explore mind-boggling images and learn the science behind what makes them work. Then, take a turn making your own optical illusion. Get ready to be eye-mazed!
Did you know that the International Space Station is the largest human-made space object? Something that big might seem like it can't move fast--but the ISS cruises through space at about 5 miles (8 km) per second! Spend some time on this massive, speedy space station to learn about how ISS crew members work on incredible science experiments and stop their food from floating away in low gravity. Discover extreme facts about the International Space Station in this fun and kooky book.
Hurricanes are battering the coastlines, heat waves and droughts are drying up crop fields, wildfires are tearing through ancient forests, and winter storms are sending deep freezes into parts of the world where the mercury rarely drops that low. What on Earth is causing these terrible storms? As Earth's climate is changing, storms are becoming more intense and frequent--and in some cases are making matters worse. Uncover the problems of climate change, explore its impact on severe storms, and dive into what we can do to help. Approachable text and engaging images bring this timely topic to life.
