When Thomas Jefferson negotiated the Louisiana Purchase in 1803, he needed a team to survey that vast, unknown expanse of land. He chose Meriwether Lewis and William Clark. Together, they led the Corps of Discovery, a team of intrepid explorers across a wild, dangerous country. Readers will understand the impact Lewis and Clark''s expedition had on American history in this detailed account. Follow their journey across roaring rivers, vast plains, and untrod paths, and learn about the Native Americans they met, the fierce wildlife that threatened their lives, and the hunger, sickness, and injury that dogged them from start to finish.

As spectacular as its creation was, the fall of the Mongol Empire was just as remarkable. Its descent into chaos was signaled by inter-family rebellion across the four khanates established by Genghis Khan. As weaker Mongol leaders struggled to retain control, drought, flood, famine, and the bubonic plague eventually contributed to the collapse of each khanate. As this volume amply demonstrates, though the Mongols were fierce warriors, their legacy also includes a culture of honor and discipline, centralized government structure, trade promotion and communication routes, and religious tolerance—all of which helped spread wealth, information, and technology across two continents.

Most scientists agree that Earth is warming rapidly. Glaciers are melting and rising seawaters are submerging islands and coastal cities. In the coming decades, millions will likely have to escape extreme weather caused by climate change. Some scientists say we need to act faster and with radical new technologies—now—to save our planet. They propose geoengineering, or "engineering Earth," to reset our global thermostat. Ideas include thickening clouds with chemicals to reduce the amount of sunlight and pulling carbon dioxide from the air with machines. However, critics say that geoengineering could backfire and create even worse weather. Is geoengineering too risky? Or is it our best hope of survival?

Have you ever tried to come up with ways to solve a problem in your community? Wangari Maathai worked to solve an environmental crisis and help people at the same time. When Maathai was young, it was unusual for girls in Kenya to go to school, but she was determined to learn more about science and nature. As an adult, she noticed that people were cutting down too many trees. Maathai knew that forest loss was bad for the health of the environment and people. She started the Green Belt Movement, which educated women in rural villages and paid them for every tree they planted. The program helped plant millions of trees and brought money to the villages. For her environmental and human rights work, Maathai became the first African woman to receive the Nobel Peace Prize.

After local fishers noticed a large swarm of fish in an unlikely area in the Gulf of Mexico, a team of divers found a unique, thriving ecosystem, full of fish, crustaceans, and other unusual organisms. The region did not contain a reef, a shipwreck, or similar habitat that would attract these creatures. Why were they there? They were feasting on the remains of an ancient cypress forest. The ancient trees had been undisturbed for more than fifty thousand years before finally being uncovered by Hurricane Ivan in 2004. But how did this forest come to be underwater? And what other treasures might be discovered there? A group of scientists wanted to investigate this unusual site. Some were interested in an organism found in the underwater forest—the shipworm—that could potentially be used for the creation of life-saving medicines. Others wanted to learn what the forest might reveal about climate change. Follow along as Jennifer Swanson explores the wonders of the lost forest, from its history and discovery to the scientists’ expeditions to collect samples and map the forest.

Everything moves! Kids run around the playground, cars drive on the road, and balls fly through the air. What causes all this motion? Physics! Forces and motion rule the way everything moves through space. In Explore Forces and Motion! With 25 Great Projects, readers ages 7 through 10 discover that the push and pull of every object on the planet and in space depends on how a force acts upon it. Things float because of a force called buoyancy, we stick to the ground because of a force called gravity, and we make footprints in sand because of a force called pressure. Physics becomes accessible and interactive through activities such as a experimenting with a water cup drop, building a bridge, and spotting magnetic field lines. Simple machines such as levers, pulleys, and wedges are used as vehicles for discovery and comprehension of the foundational concepts of physical science. Using a theme familiar to everyone—motion—this book captures the imagination and encourages young readers to push, pull, twist, turn, and spin their way to learning about forces and motion.

A women-led team of scientists protect the Amazon rainforest from destruction as readers get a firsthand account of real-life fieldwork in action. A compelling, nonfiction, photo-illustrated STEM read for 8-12-year-olds who aspire to be future scientists, environmentalists, and conservationists! Over 22 years, a team of scientists from the Field Museum in Chicago has helped conserve 28.9 million acres of the Amazon rainforest. Follow the team as they race to gather data over three precious weeks in the field. During rapid inventory, information is gathered in two ways: Biologists trek through mud and rain and count every animal and plant they see, recording everything that flies, swims, crawls, slithers, or walks. They then look at key plant and animal groups to assess the health of the ecosystem. Social scientists visit villages, speaking with local people about their desires and goals for the land, as each community has developed its own way of taking care of its environment. The team then makes a compelling, evidence-based case for conservation. Developed in partnership with the Field Museum, this action-packed book focuses on Rapid Inventory 30, which is conducted in Colombia with the help of local and Indigenous scientists and community members. Photographs from the scientists themselves give readers a glimpse into real-life fieldwork in the Amazon that will captivate STEM readers and the next generation of scientists.
