Big discoveries also come with big risks. The excitingly designed Dangerous Journeys series (6 titles) presents both the thrills and dangers of exploration in a high-low format that combines short, boxed text passages with colorful, dramatic photos of explorers in action. Each volume describes an extreme destination, why it's perilous, and how explorers prepare for the dangerous mission. Exploring the Deep Sea focuses on the technology needed to make the extreme cold and pressure of this environment safe for human explorers. Each book features a variety of infographics, from a map of the destination and a spotlight of a notable explorer to a chart with potential dangers (e.g., "What Happens When You Breathe Carbon Monoxide?") and a "Planning Your Journey" page with thumbnail photos of key steps. A concluding glossary and related resources extend the learning in this high-interest series with special appeal for reluctant readers.
